Full textAbstract:
L'usage de l'informatique dans le secteur de la santé et des services sociaux ne constitue pas seulement une réforme technologique de la gestion des services publics. L'informatisation des services sociaux s'insère dans un processus sociopolitique qui influence les pratiques institutionnelles et, par le fait même, les citoyens et citoyennes qui bénéficient des services. Afin de comprendre cette influence, l'auteur analyse, d'un point de vue communautaire et critique, le rôle de la loi 120 dans une perspective d'informatisation idéologique de la production sociale des services publics et communautaires. Il nous présente sa conception de la productique sociale comme un processus dynamique liant la communautique (forme de socialisation contrôlée), l'épidémiologie sociale (la programmation) et le social automatisé (gestion du travail social assisté par ordinateur) en tant que pratiques modernisées de la gestion technocratique. Selon cette conception, ce type de gestion aurait des effets de désocialisation et d'exclusion des espaces institutionnels et communautaires sur les personnes particulièrement marginalisées, telles que les jeunes.

El objetivo de la investigación es determinar la relación entre la gestión pedagógica directiva y los Proyectos Educativos Productivos en las Instituciones Educativas del distrito de Azángaro provincia de Yauyos –Lima, 2020. Para su desarrollo se consideró la investigación correlacional en la que se analizarán el vínculo estadístico entre dos variables, aplicándose un cuestionario para cada variable aplicado a una muestra de 88 docentes, cuyos datos recolectados fueron procesados mediante el programa estadístico SPSS, además se empleó Rho de Spearman con un margen de error 5%. Los resultados hallaron un nivel de correlación de 0,904 evidenciando relación entre gestión pedagógica directiva y proyectos educativos productivos, debido a los resultados mayoritarios de la gestión pedagógico directivo considerado de indiferente por el 73.9%, lo cual está vinculado a los proyectos educativos productivos visto por el 71,6% con una frecuencia de a veces. Del mismo modo, se confirmó la relación de la primera variable con las dimensiones pertinencia, objetividad, compromiso y creatividad. Por ello, se concluyó que una gestión intermedia de los directivos dentro de la institución limita el interés institucional (docentes, estudiantes y padres de familia), para el desarrollo efectivo de los proyectos educativos.

Swine housing must promote an adjusted environment for thermal comfort and high animal productivity without negatively affecting the sow performance and reproductive response. This study evaluated the use of distinct environmental cooling equipments on sow performance, both on the gestation and on nursing in open sided housing. Two treatments were tested in the gestation building: natural ventilation and mechanical ventilation associated to fogging; while in the nursing rooms three treatments were tested: natural ventilation; mechanical ventilation; and evaporative cooling with forced ventilation. Sows were randomly chosen from the same genetic lot form six combined treatments. The evaporative cooling system in the farrowing room differed for piglet performances, at birth (4% higher) and on daily weight gain (15% higher), and also for sow physiological response improving the respiratory rate (8%) and back fat thickness (3%), without influencing skin temperature. The use of evaporative cooling directed to the sow head during nursing improved the physiological and productive results.

L'étude phytosociologique de la forêt classée de Pahou au Sud du Bénin a été réalisée dans une perspective de gestion durable. L'évaluation des communautés végétales a été menée suivant une approche de phytosociologie synusiale intégrée. Les sols ont été caractérisés d'après leurs profils pédologiques et leurs propriétés physico-chimiques. Les paramètres sylvicoles ont été collectés au sein de placettes temporaires, chacune de 300 m² de surface, installées au sein de sites représentatifs de la forêt. Cette étude a permis d'identifier et de décrire cinq phytocénoses (communautés végétales). Deux cent quarante-sept (247) espèces de plantes ont été inventoriées dans le sous-bois des plantations d'Acacia auriculiformis de la forêt de Pahou ; elles appartiennent à deux cent neuf (209) genres et soixante et onze (71) familles. Les accroissements moyens annuels en diamètre et en hauteur variaient respectivement de 1,2 à 3,1 cm/an et 1,4 à 4,2 m/an. Ces résultats ont montré que les plantations d'acacias de Pahou sont parmi les plus productives d'Afrique de l'Ouest. Les relations entre les facteurs écologiques et la productivité des différentes communautés végétales, ont permis d'identifier et de cartographier quatre types de forêts dont la plus productive est représentée par la communauté végétale Barteria nigritana et Rauvolfia vomitoria et la moins productive par la communauté à Axonopus compressus et Scleria depressa. Des recommandations ont été faites pour utiliser ces indicateurs phytosociologiques en tant qu'outils de gestion durable de la forêt. (Résumé d'auteur)

The Canadian Council of Forest Ministers (CCFM), established in 1985, is composed of the federal, provincial and territorial Ministers responsible for forests. Its role has evolved into one that stimulates the development of policies and initiatives for strengthening the forest sector, including the forest resource and its use. One of the most important functions of the CCFM is that it sets the overall direction for the stewardship and sustainable management of Canada's forests by addressing issues and stimulating joint initiatives. Under its guidance, four successive National Forest Strategies and three Forest Accords have been developed. Another major achievement has been the development of the CCFM Criteria and Indicators Framework: Defining Sustainable Forest Management - A Canadian Approach to Criteria and Indicators. Today, the CCFM works under five strategic themes: sustainable forestry; international issues; forest communities; science and technology; and information and knowledge. The ongoing, positive cooperation between the two levels of government helps maintain healthy and productive forests and their sustained contribution to Canadians' economic, environmental and social well-being over the long term.

The study was conducted at Sylhet Govt. dairy farm to evaluate the productive and reproductive performance of Jersey× Frisian (J×F), Jersey × Local (J×L) and Sahiwal × Local (SL×L.) crossbred during the period of April 2007 to August 2009. Data on milk yield and different reproductive traits like lactation length, milk yield, length of dry period, service per conception, gestation length and post-partum heat period were evaluated. Results indicated that milk yield, length of dry period, service per conception and post-partum heat period were significantly affected (P<0.01) by different crossbred. However, lactation length and service per conception were significantly affected (P<0.01) by parity and interaction of breed × parity. The highest lactation length was observed for the genotype Jersey × Friesian (J×F) and the lowest was Jersey × Local (J×L) in the first and second lactation. The highest milk yield was observed for the genotype J×F and the lowest was J×L. The highest length of dry period was observed in SL× L and lowest was J×F. Furthermore maximum services were required for J×F. The highest gestation length was observed for genotype SL×L. The highest post-partum heat period was observed J×F. The overall reproductive performance of different crossbreds were varied.DOI: http://dx.doi.org/10.3329/pa.v22i1-2.16466 Progress. Agric. 22(1 & 2): 47 - 54, 2011

The present work aims to propose a model of knowledge management for agricultural teaching based on ontologies. Through identification of the business model, business processes, intellectual capital and ontologies, the relationships between each of the parts of the model are described, and the technological elements that support it are presented. From the point of view of knowledge management and ontologies, the model that guides the innovative university is developed, where Santa Lucía Campus of the Universidad Politécnica Territorial de Mérida (UPTM) is the case study. This model describes the elements that define the knowledge of an Agricultural Production Unit from the university, so that it can incorporate the know-how of knowledge management and collaborative learning articulated with ICT applied to educational-productive management in the agricultural sector. Ontology is used as the main mechanism to represent knowledge, defining within a context or domain the meaning of the terms and their relationships. Through the model the technological bases and knowledge necessary in the teaching of agriculture in a university nucleus are structured.Keywords: Ontology, Knowledge Management, Agro-business, Business Model.

This study was undertaken to assess the reproductive performances of sheep at field level of Rajshahi and Mymensingh district of Bangladesh during January to December, 2016. A total of 52 farms (26 each in Rajshahi and Mymensingh) were selected for determining the reproductive parameters of ewes. Ewe lambs in Mymensingh reached puberty at significantly (P<0.03) younger age (186.9±18.4 days) than in Rajshihi (199.9±24.9 days). The average age at first pregnancy was 201.4±20.0 days in two regions. Similarly, the ewes in Mymensingh was lambing at significantly (P<0.002) early age than ewes in Rajshahi (356.0±6.8 days vs. 372.7±27.8 days). The observed duration of oestrus at Rajshahi and Mymensingh was 36.0±6.7 hrs and 36.0±7.3 hrs, respectively. The gestation length varied from 145 to 150 days. The average gestation length was 147.9±3.4 days in two regions. The gestation length was not significant (P˃0.05) in the ewes between Rajshahi and Mymensingh (148.7±3.4 and 147.1±3.2 days; respectively). The pooled over litter size was 1.6±0.2 in two regions. However, there was no significant (P>0.05) difference in litter size of ewes in Rajshahi and Mymensingh region (1.7±0.2 vs. 1.6±0.2). The pooled lambing interval was 193.9±21.7 days in two regions. Mean birth weights of lambs, weaning weight and mature weight were 1.7±0.6 vs. 1.3±0.1 kg; 8.9±2.7 vs. 6.9±1.0 kg and 24.9±7.3 vs. 19.4±2.7 kg in Rajshahi and Mymensingh, respectively. These reproductive parameters were significantly higher (P<0.001) in Rajshahi compared with in Mymensingh. The reproductive parameters are almost similar between confined and the traditional management system if the farms are well managed.Asian J. Med. Biol. Res. March 2018, 4(1): 63-68

In this study, a maternal feed restriction (MFR; 105 g/d) in primiparous rabbit does was applied from day 0 to 7 post artificial insemination (AI) (R07, n = 96), from day 7 to 21 post AI (R721, n = 92), from day 0 to 21 post AI (R021, n = 94) or fed ad libitum during whole pregnancy (Control, n= 92). Feed intake (FI) was measured after MFR was over. On day 28 of gestation, fetoplacental development was evaluated (n = 11/group) and the productive parameters of the remaining dams were analyzed. Plasma free tri-iodothyronine (T3) and thyroxine, glucose, insulin, non-esterified fatty acids (NEFA), and corticosterone were analyzed during gestation and lactation (n = 5/group). After MFR, all groups significantly increased their voluntary FI. The longer MFR was, the lower the weight and length of the fetuses, but no long-term effects over litter performance were observed. R021 groups had the lowest T3 and the highest NEFA concentrations during pregnancy and showed insulin resistance at the end of gestation, but during lactation, energy homeostasis was balanced in all groups. MFR did not affect corticosterone concentrations. In conclusion, the ration setting applied slightly involved the energy homeostasis and metabolism of the animals, but their overall metabolic condition, productive performance and welfare were not compromised.

An experiment was conducted at AZ-Zahra Farm, Sandakan, Sabah, Malaysia to investigate the productive and reproductive performance of Saanen dairy goat. Body weight at different ages were collected once while birth weight was collected when does gave birth. On the other hand, milk production of each individual per day was received continuously for three months. The data on reproductive parameters such as length of estrus cycle, duration of estrus period, age at puberty, gestation length, age at first kidding, litter size, birth weight and kid mortality were noted. Descriptive statistics such as number, percentage, mean, standard deviation were performed. T-test was also conducted to know the statistical difference between the groups. Result demonstrated that body weight increases significantly (p<0.01) with the advancement of the age. The highest daily milk yield was found in 2-3 years of age. Dam with multiple kids produced more milk than dam with single kid. Estrus cycle of Saanen goats was found 21 days, the average estrus period duration was 2.75 days, age at puberty was 8.33 months, first kidding age was 14.2 months and gestation period was 150 days on an average. With the increase of the age of dam litter size increased. Meanwhile average birth weight increased as age of dam increased from 2.85 kg in 1 year to 3.26 kg in 3 years. Male kids born heavier than females (3.23±0.62 vs. 2.75±0.58 kg) and single kids were heavier than twin kids (3.07±0.66 kgvs2.70±0.28 kg). Low mortality rate of kids was recorded in this study (6.4%). It can be concluded that the overall productive and reproductive performances of Saanen goat at AZ-Zahra farm were within the acceptable level and the variation recorded in different parameters is very much usual.

Cet article examine les développements récents de la négociation collective et de l'organisation du travail dans l'industrie québécoise du papier. L'analyse des négociations menées ces dernières années par les syndicats du papier affiliés à la CSN révèle le caractère central des stratégies de flexibilisation du travail chez les employeurs, et de protection de l'emploi du côté syndical. La flexibilité fonctionnelle constitue l'aspect essentiel des changements en cours dans cette industrie depuis la fin des années 1980, les employeurs cherchant à améliorer l'efficacité productive par une rationalisation des tâches et une réduction des emplois. Dans certaines usines, la réorganisation du travail a suscité un renouveau de l'action syndicale à travers l'implication des salariés et de leur syndicat dans la gestion de l'entreprise.

Full textAbstract:
Nutritional management during gestation is critical to optimize the efficiency and profitability of beef production systems. Given the essentiality of trace minerals to fetal developmental processes, their supplementation represents one approach to optimize offspring productivity. Our research group investigated the impacts of supplementing gestating beef cows with organic-complexed (AAC) or inorganic sources (INR) of Co, Cu, Mn, or Zn on productive and health responses of the progeny. Calves born to AAC supplemented cows had reduced incidence of bovine respiratory disease and were >20 kg heavier from weaning until slaughter compared to unsupplemented cohorts. Complementing these findings, heifer progeny born to AAC supplemented cows had accelerated puberty attainment. Collectively, research demonstrates supplementing trace minerals to gestating beef cows may be a strategy to enhance offspring productivity in beef production systems.

Abstract Supplementation with fatty acids (FA) during late gestation regulates offspring development; however, its effect in the first third of gestation is unknown. The objective of this study was to evaluate the effects of with eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) supplementation during the first third of gestation on productive performance and hypothalamic neuropeptides on the offspring. Seventy-nine post-weaning lambs, born of sheep supplemented in the first third of gestation with 1.5% Ca salts rich in monounsaturated FA (MUFA) or PUFA [DHA and EPA; Dam supplementation (DS)], were distributed in a 2x2 factorial arrangement of treatments to finishing diets containing MUFA or PUFA [Lamb supplementation (LS)]. The experiment last for 56 d. Measurements dry matter intake (daily), body weight and plasma metabolites (every 14 d) were taken. Twenty-four lambs were slaughtered and hypothalamus were obtained for mRNA concentration. The data were analyzed with a mixed model in SAS (9.4) using repeated measurements. There was a DS x LS interaction for BW (P < 0.10) where LS with PUFA born from DS with MUFA were heavier than the other 3 treatments. Lambs born from DS with MUFA have a greater DMI (P < 0.01). There was a time x DS effect (P < 0.05) for plasma glucose and non-esterified fatty acids (NEFA) concentration, due to a greater concentration for glucose and lower for NEFA on the lambs born from DS-MUFA at weaning but not on d 56. Lambs born from MUFA supplemented dams had a greater (P ≤ 0.05) hypothalamus mRNA concentration for CART, GH-receptor, KISS-1, leptin receptor, POMC, and NPY receptor Y1. There were no LS effects (P > 0.05) for these neuropeptides. These results indicate that supplementation with fatty acids during early pregnancy change productive performance, metabolic, and neuropeptides of lambs independently of the final diet.

Full textAbstract:
The aim of this study was to investigate the long-term effects of increasing feeding allowance during mid-pregnancy in sows. A total of 103 PIC pregnant sows (mixed parity) were allocated to two treatments: control (C, n = 49) were fed 2.5-3.0 kg d-1 (12.1 MJ ME kg-1) and extra-fed (E, n = 54) received +2.0 kg d-1 of the same feed from day 45 to 85 of gestation over three consecutive cycles. Body weight, backfat thickness (BF) and loin depth were measured on days 45 and 85 of gestation, farrowing and weaning. Litter and sows performance were recorded during lactation and post-weaning. Overall culling rates were 61 and 67% for C and E groups, respectively. After three cycles, E sows showed a positive BF balance in contrast to C sows (E = +1.46 mm and C= -1.81 mm, P < 0.05). In cycle 3, E sows presented greater piglet birth weights than C sows, being mainly evident in sows that were nulliparous at the onset of the experiment (P < 0.05). Extra-fed sows showed a greater incidence of mastitis-metritis-agalactia syndrome than C sows (P = 0.003). Thus, increasing feeding allowance during mid-pregnancy positively affected BF balance and birth weight in nulliparous, but impaired the sows’ ability to produce milk in the long-term.

This paper analyzes the relationship between the productive efficiency and the Online Social Networks - OSN in the Spanish telecommunications firms. First, a data envelopment analysis (DEA) is used and several indicators of business "Social Media" activities are incorporated. In a second stage, a logistic regression model regression is applied to characterize the efficient enterprises. Results show that the company's ability to absorb and utilize this OSN is a key factor in improving the productive efficiency. These results on the combined use and different management capabilities of OSN point to a definition of OSN as a heterogeneous resource. This paper presents a model for assessing the strategic performance to address their presence and activity in OSN.

The productive and reproductive efficiency of Red Chittagong cattle (RCC) reared at the Bangladesh Livestock Research Institute (BLRI) farm was evaluated. A total of 46 RCC of different categories were considered under this study. Parameters studied were birth weight, weight at 3, 6 months of age and adult body weight, growth rate, daily milk yield, lactation length, lactation yield, age at puberty, weight at puberty, age at first calving, post partum estrus period, service per conception, calving interval and gestation length of RCC were collected and recorded. The birth weight differed significantly (p<0.01) between male and female and the average birth weight of RCC calves at farm level was 14.87 kg. The growth rates and adult body weight also differed significantly (p<0.05 and p<0.01) between male and female except in growth rate from 3 to 6 months of age. The average daily milk yield, milk yield per lactation and lactation length of RCC were 2.24 kg, 526.81 kg and 238 days, respectively. The age at puberty, service per conception, post partum estrus period and calving interval of RCC heifers and cows were 15 months, 1.15, 40 days and 11 months, respectively. It can be concluded that the RCC is a genetically and economically superior variety of Bangladesh.DOI: http://dx.doi.org/10.3329/pa.v18i2.18166 Progress. Agric. 18(2): 109 - 114, 2007

Full textAbstract:
This paper aims to show the trajectory of the “campesino” notion in the Colombian institutional context. “Campesino” has been used as a territorial management strategy to organize a set of technologies, populations, crops, and soil use. Peasant organizations in Colombia today seek to position this notion as a category of effective citizenship, and social ordering of their territories. To do this, we carried out a descriptive study of the configuration of the figure of the peasant from the institutional level facing the context of Nariño. Methodologically, we used different qualitative research tools to dig in an ethnographic perspective of the agrarian, environmental, and social organization history of the region. We raise some reflections on current uses and disputes through institutional frameworks that seek, or omit, their recognition as an agrarian and citizenship category. Finally, we provide some reflections on the strategies and frameworks to regulate rural spaces based on subject-centered categories and territorial policies. The importance of this analysis is the visibility of the strategies of community organizations to build, from their local experience, notions of peasantry focused on the recognition of citizenship, beyond the functional and productive character posed by the State.

Full textAbstract:
Dans les troupeaux allaitants, les projets techniques des éleveurs associés à leurs pratiques d’élevage conduisent à une grande variabilité des productivités animales et des répartitions de la production dans le temps. A partir de la synthèse de six études portant sur le fonctionnement de troupeaux allaitants, l’objectif de cet article est d’analyser l’intérêt de la notion de trajectoire productive des femelles reproductrices pour formaliser le fonctionnement du troupeau. Dans une première partie, les six conduites de la reproduction et du renouvellement/réforme sont présentées en lien avec différents projets techniques. Dans la deuxième partie, l’analyse montre que les pratiques d’élevage visent à réduire ou au contraire à amplifier la diversité intra-troupeau des trajectoires productives des femelles reproductrices. Les conséquences pour la modélisation du fonctionnement du troupeau sont analysées dans la troisième partie. Formaliser le fonctionnement du troupeau nécessite d’intégrer à la fois les décisions de l’éleveur et les comportements biologiques des femelles. Pour simuler la construction des performances du troupeau, il est alors nécessaire de représenter au moins les groupes de femelles ayant les mêmes comportements productifs, ainsi que les entités de gestion rendant compte des mouvements de femelles entre ces groupes. La trajectoire productive est un indicateur pour l’expression des règles de réforme, mais aussi un indicateur de performance. Les interactions entre les décisions de l’éleveur et la biologie des individus impliquent de tenir compte des effets différés des pratiques sur la pérennité des effectifs de reproductrices.

Background: The Black Bengal goat (BBG) is well adapted food animals with profitable productive and reproductive traits being naturally reared to enhance economic status and food security in rural people. Bangladesh government has taken program through establishment of ‘Government Goat Development Farms’ (GGDF) to enhance the goat rearing activities of the smallholders at rural level but the research reports on the productive and reproductive performances of goats in these GGDF are very limited. Objective: The main objective of this study was to evaluate the productive and reproductive performances of the BBG reared in semi-intensive system at the Rajshahi GGDF Materials and Methods: The Rajshahi GGDF had 398 goat populations of which 121 does were selected to study the productive and reproductive performances during the period from July 2010 to June 2011. The age of first estrus, conception rate by natural service, gestation length, post-partum heat, kidding interval, litter size, survivability of kids, morbidity and mortality of kids and their seasonal influence were studied. Results: The age of young female BBG showed 1st estrus varied from 180 to 270 with an average of 204 27 days. The conception rate varied from 88 to 100 with an average of 97% with natural services. The gestation length varied from 145 to 182 with an average of 150 5 days. The post-partum heat period varied from 60 to 90 days with an average of 69 7 days. The kidding interval varied from 199 to 268 with an average of 219 13 days. The litter size varied from 1 to 3 with an average of 2. Out of 234 kids borne, 47.44% were male and 52.56% female with higher mortality in male (10.81%) than female (5.69%) with an overall average mortality of 8.12%. There was no significant influence of season and parity on the birth weight of kids. However, the heavier birth weight of kids was recorded in male (1.38 kg) than female (1.17kg) kids. The birth of twin kids (56.41%) was found significantly (p < 0.0001) highest in comparison to triplets (26.92%), single (11.54%) and quadruplet (5.13%). Conclusions: The results support promising breeding and reproductive efficiency of BBG under local environmental conditions and therefore, there is a need to be improved milk yield of dam and control of morbidity and mortality in BBG kids. It may be concluded that the productive and reproductive performances of the BBG reared by using semi-intensive system of management appears to be encouraging at the Rajshahi GGDF which could be extended and compared to research findings with other four GGDF in Bangladesh.

It specifically analyzes how it is carried out and how the management of water resources can be improved for its integral management. It is emphasized that what is really important is to give a comprehensive treatment to the water system, its collection and evacuation basins, regardless of whether the management system itself is integrated or not. To facilitate the analysis a systemic approach is used. The conceptual framework provides a classification of management levels into four categories: scientific-environmental, economic-productive, technical-normative and political-social; these levels are associated with different management areas. In order to conduct environmental management processes, in particular for management of water resources for multiple use, two delimitation criteria must be taken into account: the political-administrative and the geographical-ecological. If management systems are brought together in relation to these two limits, it is possible to arrive at a more effective form of environmental management.

Aim. To investigate the vitamin D status in highly productive cows during winter housing period and effect of cholecalciferol by various ways of vitamin D 3 injection to cows in last days of gestation and after calving. Methods. Enzyme-linked immunoassay, spectrophotometry. Results. It has been stated that intramuscular injection of cholecalciferol into cows caused increase of the vitamin D 3 active metabolite – 25-OHD 3 , calcium, phosphorus and magnesium levels together with decrease of alkaline phosphatase level in pre- and post-natal periods. Oral supplementation makes little infl uence on the studied blood parameters of cows. Conclusions. Extrabuccal administration and oral supplementation of cholecalciferol in winter housing period to high-yield cows in the last days of gestation and after calving is accompanied by increased levels of its metabolites and their effect on mineral metabolism in the postnatal period. The nature of these changes depends on the mode of vitamin D administration and the physiological state of the cows.

Aim: Nutrition plays a key role in the production of pigs, especially in pregnant sows, where modifications in nutritional requirements can affect their productive performance. The aim of this study was to evaluate nutritional supplementation with soybean expeller in sows during the last third of the gestation period and its effect on litter birth weight. Materials and Methods: A quasi-experimental study was conducted on a farrow-to-finish farm, where 192 sows were equally assigned to treatment and control groups. Several variables were recorded at both the sow and piglet level. The treatment group consisted of piglets from 95 sows supplemented with soybean expeller during the final phase of gestation (20 days), and the comparison group consisted of piglets from 97 sows fed only with a commercial balanced ration (control group). Results: Soybean expeller supplementation increased individual piglet weight by 190-270 g, and the increased number of live piglets could decrease the weight of each piglet. Moreover, the number of piglets weighing <900 g decreased by 10% as compared to the control group, indicating that supplementation could improve pre-weaning mortality. Conclusion: Our results suggest that soybean expeller supplementation in sows during the last third of the gestation period could improve production performance, especially on organic farms.

A total 131 dairy cows of two genetic groups as IG (117 heads) and HF (14 heads) were selected randomly. The study found that the average milk yield per day of HF and IG cows were 7.64±1.74 and 1.75±0.07 liters/day, respectively. The milk yield was found significantly (p<0.01) higher in HF cows than of IG cows. The lactation period of HF was significantly (p<0.05) higher than of IG cows. Age at first calving of IG cows was significantly (p<0.01) 4 months higher than HF cows. The number of service per conception was almost similar for HF and IG cows. Higher significant difference was found in Post-partum oestrus (p<0.05), dry period (p<0.01), calving intervals (p<0.01) of IG than HF cows. The gestation length of HF and IG cows was significantly indifferent. Above biological studies mentioned better productive and reproductive performance of HF cows than IG cows.Bang. J. Anim.

Des variations de biomasse aérienne, en relation avec le niveau de pluviométrie, ont été observées, de même que des rapports feuilles/tiges plus élevés en saison sèche en liaison avec une augmentation de la masse surfacique. En ce qui concerne les variables d'état des couverts, D. swazilandensis présente durant la saison sèche une relation linéaire analogue à celle observée chez les graminées tempérées, avec une forte corrélation entre indice foliaire et hauteur de végétation. Cette corrélation existe en saison sèche et pluvieuse chez B. humidicola. Cette espèce est plus productive et moins sensible à la sécheresse que D. swazilandensis, mais est moins riche en matières azotées. Des performances zootechniques comparables sont obtenues pour les deux espèces. L'étude de ce mode de gestion doit être poursuivie dans le cadre de la saison sèche par ajustement de la charge et utilisation de réserves fourragères.

The aim of the study was to evaluate productive and reproductive performance of Prestice Black‑Pied sows including losses of piglets from birth to weaning in conditions of two farms. The experiment involved one hundred sows of Prestice Black‑Pied pig from the 1st to the 7th parity (50 from farm A and 50 from farm B). The evaluation of productive parameters revealed a highly statistically significant difference (P ≤ 0.001) between gilts of the observed farms in percentage of lean meat. Backfat thickness was 0.19 cm lower in gilts from the farm A, which is a very highly statistically significant difference (P ≤ 0.001). The evaluation of reproductive performance showed, that age at the time of the first insemination and farrowing was significantly higher (P ≤ 0.05) in gilts from the farm A compared to gilts from the farm B by 38 days on average. The analysis also indicates that there was no significant difference in length of gestation, total number of piglets and numbers of live-born and reared piglets between the sows of the evaluated farms. A highly statistically significant difference (P ≤ 0.01) was found in number of stillborn piglets. Interval length was significantly longer (P ≤ 0.05) in sows from the farm A, by 14.29 days. The evaluation of losses of piglets revealed a significant difference (P ≤ 0.05) between the farms in favor of piglets from the farm A.

Full textAbstract:
In mammals, the mass-specific rate of biomass production during gestation and lactation, here called maternal productivity, has been shown to vary with body size and lifestyle. Metabolic theory predicts that post-weaning growth of offspring, here termed juvenile productivity, should be higher than maternal productivity, and juveniles of smaller species should be more productive than those of larger species. Furthermore because juveniles generally have similar lifestyles to their mothers, across species juvenile and maternal productivities should be correlated. We evaluated these predictions with data from 270 species of placental mammals in 14 taxonomic/lifestyle groups. All three predictions were supported. Lagomorphs, perissodactyls and artiodactyls were very productive both as juveniles and as mothers as expected from the abundance and reliability of their foods. Primates and bats were unproductive as juveniles and as mothers, as expected as an indirect consequence of their low predation risk and consequent low mortality. Our results point the way to a mechanistic explanation for the suite of correlated life-history traits that has been called the slow–fast continuum.

The experiment was conducted with forty four pre-pubertal stages female lambs of 12.5±2.5 kg average live weight and 7.5±0.5 months of average age. Animals were equally and randomly allocated into two feeding groups, intensive and semi-intensive feeding systems with 22 animals in each group. Under intensive system, animals were fed concentrate mixture (15.0% crude protein (CP); 11 MJ metabolizable energy (ME)/kg dry matter (DM)) at the rate of 1.5% of live weight with ad libitum green grass from May to November and supplied urea molasses straw (UMS) in place of green grass from December to April. There were no significant differences (p > 0.05) in service per conception, litter size, lambing interval, gestation length, service period, birth weight and weaning weight between intensive and semi-intensive feeding system. Reproductive traits and productive traits were not affected by feeding system. Conception rate was higher (98.0%) in semi-intensive system than intensive system (83.0%). On the other hand lamb survivability was higher in intensive system than in semi-intensive system. The semi-intensive feeding system is found to be better to rear sheep for commercial purpose compared to intensive feeding system.

Conditions for keeping and feeding pregnant sows play an important role in ensuring the behavior of future offspring. Stress of sows in the late stages of gestation can cause a negative longterm effect on the functioning of the immune system of piglets. This reduces the ability of piglets to be effectively protected against infections during lactation and weaning periods. Changes in the endocrine and neurotransmitter systems depend on the gestational period, with late pregnancy being the most sensitive phase in pigs. Ensuring optimal housing conditions for sows and newborn piglets is an important condition for the proper development of protective, feeding and behavioral reflexes and, accordingly, the realization of their productive qualities. Stress factors also affect pigs in the postnatal period of their development. The main stress-inducing factors are the conditions of feeding, maintenance and technological methods associated with ensuring veterinary wellbeing. Early social isolation during the early postnatal life of animals causes persistent changes in their behavioral responses and physiological mechanisms of adaptation. Raising pigs in a depleted environment may indicate the presence of chronic stress and, accordingly, a decrease in the level of welfare, protective and productive qualities in animals. The methods that can reduce stress and improve animal welfare is environmental enrichment and adaptation of the housing environment according to the behavioral needs of animals. Ecological enrichment can be used to preserve or restore physiological homeostasis and behavioral disorders in the post-stress period. Key words: stress, pigs, adaptation, behavior, immune system, productivity.

Full textAbstract:
Holstein-Friesian has been rated the number one cattle in the world as far as milk production is concerned. The productive potential is excellent in European countries. Animals of the same breed were imported to meet the milk demand of developing countries such as Pakistan. One thousand cattle from Denmark were imported in 1977–78 by the Balochistan government, and were kept at government dairy farms at seven locations (viz., Kalat, Khuzdar, Loralai, Mastung, Pishin, Quetta, and Zhob). The aim of this study was to determine the productive [age at first calving (AFC), birth weight (BWT), lactation length or milk yield (MY), milk yield per lactation (MYL), days in milk (DIM), and culling and mortality (C&L)] and reproductive potential [service period (SP), age at first service (AFS), gestation period (GP), and calving interval (CI)] of these imported animals while kept under the local conditions of Balochistan. Effect of localities with respect to the environmental data was also explored. Overall average values for AFS were 315 to 986 days with an average of 660.42 ± 12.42, GP 275 to 299 days with an average of 280.62 ± 0.25, and AFC 604 to 1299 days with an average of 944.08 ± 12.71. BWT ranged from 15 to 68 kg with an average of 30.12 ± 0.15, MY from 1471 to 7035 liters with an average of 3731.26 ± 40.52, DIM from 180 to 728 days with an average of 313.56 ± 3.83, and SP ranged from 29 to 886 days with an average of 240 ± 9.61, DP averaged 59.15 ± 20.61 days and CI ranged from 301 to 922 days with an average of 451.10 ± 5.55. The effects of year, season, age, and location were studied and the results revealed that the year influenced the AFS, AFC, BWT, and SP (P < 0.01); GP (P < 0.05) but not DIM and CI (P > 0.05). No effect of season on AFS, AFC, DIM, MY, SP or CI (P > 0.05) was observed, but GP and BWT (P < 0.05) were affected by season. Age influenced the GP and SP (P < 0.05) but not BWT, DIM, MY, and CI (P > 0.05). No effect of sex of the calves, type of birth, and calving number on GP (P > 0.05) was seen. Location of the farm did effect AFS, AFC, BWT, and MY (P < 0.01); CI (P < 0.05); but not GP, DIM, and SP (P > 0.05). In conclusion, differences in environment and seasonality had a variable impact on production parameters in Holstein-Friesian calves.

A nucleus-breeding flock of selected Brown Bengal goat was established in the Bangladesh Livestock Research Institute (BLRI), Regional Station, Naikhongchari, Bandarban, with the objective of characterization, conservation and improvement of the breed. A total of 69 does of different generations (Foundation = 07, Generation one = 32, Generation two = 23 and Generation three = 07.) and 07 bucks (All were first generation) were used to study the genetic parameters of Brown Bengal goat on productive and reproductive traits. The studied Animals were bred naturally. Goats were reared under semi-intensive management system in which goats were browsing in nature and allowed to graze in field as well as mounting in hills. All goats were housed in a plastic made floor house and allowed to graze 6-8 hours in a day and concentrate was offered twice daily during morning and evening at the rate of 1% of their body weight per day. The adult body weight of hilly goat was 20.95 kg. The phenotypic characteristics like the face, horn, ear and udder length were 15.56, 7.18, 12.19 and 12.67 cm respectively. On the other hand the hearth girth, front leg, hind leg and body length were 61.51, 46.8, 49.48 and 55.24 cm respectively. The gestation length, kidding to first heat, kidding to conception and kidding interval were 148.52 ± 1.06, 33.48 ± 2.85, 33.40 ± 1.98 and 176.86 ± 1.98 days, respectively. According to parity the GL, AFH, KC and KI were not followed trends up to 3rd parity but kid birth weight was increasing trends with increasing parity up to fifth. The birth weight of male kid (1.25 ± 0.25 kg) was higher than that of female kid (1.13± 0.27 kg). The highest birth weight (1.24±0.02 kg) was found in single birth. According to litter size the birth weight of single kid (1.24 ± 0.01 kg) stood first followed by twine (1.20 ± 0.01), triplet (1.1±0.03 kg) and quadruplet kids (0.93±0.08 kg). . The productive and reproductive performances of brown Bengal goat were not affected by parity. Birth weights of kids were significantly varied with birth type.Asian J. Med. Biol. Res.

Full textAbstract:
A hybrid stochastic model was developed including discrete events and agent-based simulations in order to identify the productive parameters and management criteria that most affect meat sheep production. A sheep herd on a pasture termination system, without weaning and with natural mating, was outlined. In order to devise this herd, a pre-existing database from between 1999 and 2013 was used. This conceptual model included the flushing, mating, gestation, lactation, termination and maintenance phases. Health, feeding and management criteria were also considered and recommended. Simulation scenarios were built which were later evaluated by regression analysis. The net operational margin was between R$ 11 741.80 and R$ 21 389.80, and an average of R$ 14 412.14 ± R$ 3 873.02 for different scenarios. Food costs had the greatest impact (25.4%) in relation to operating costs, while health costs were the lowest (1.3%). The abortion rate showed a higher linear response in contrast to the birth rate and the net operating margin, upon analysing ewe productivity parameters. However, neonatal mortality showed the greatest impact on net profit and on general lamb mortality. Carrying out economic analyses within the livestock sector can make a difference within such a competitive market, where prices are not controlled, only costs. The use of discrete event and agent-based simulation methodologies allowed for the assessment of different approaches to sheep production. The present study demonstrated the tool’s potential within the scope of meat sheep production, but this model can act as a guideline for other animal production systems.

Antecedentes: Las empresas que hacen parte del sector constructivo, debencomprometerse con la preservación del medio ambiente, la minimización del riesgo para las personas y la generación de confianza para los clientes a través del desarrollo de la cultura de la calidad y la eficiencia operativa. Los sistemas integrados de gestión, nacen en la década de los noventa como evolución de los ya existentes sistemas de calidad, de gestión ambiental y de seguridad industrial. Como antecedentes de los sistemas integrados se cuentan el MRP (Manufacturig Resource Planning) y el MAP (Manufacturig Automation Protocol). Objetivo: El objetivo del proyecto se centra en la identificación de la relación y puntos de convergencia existentes entre las normas, para la implantación del sistema integrado de gestión (SIG), en empresas de ingeniería civil que desarrollen su actividad económica en el sector constructivo colombiano. Metodología: Se realiza un análisis de la estructura de las normas objeto del estudio y se identifican los puntos de convergencia y divergencia con el fin encontrar una estructura troncal que sirva a los gerentes de las empresas de construcción como insumo de decisión para implantar sistemas integrados en gestión. Resultados: El producto fundamental es la articulación de las tres normas y su caracterización en el marco del ciclo PHVA (Planear, Hacer, Verificar y Actuar) para identificar aspectos convergentes y de complementariedad entre ellas y establecer la plataforma documental mínima para el sistema de gestión integrado. Conclusiones: Los sistemas integrados en las empresas de la construcción son una alternativa de operación productiva y organizacional que les confieren características de visibilidad, credibilidad, competitividad y rentabilidad para competir en escenarios dinámicos de negocios y garantizar el cumplimiento de los compromisos contractuales en el marco de mercados globales altamente exigentes.Abstract Background: Companies that made part of the construction sector must be committed to the preservation of the environment, minimizing the risk to people who works for each organization and generate confidence for its clients through the development of culture quality and operational efficiency. Integrated management systems started in the nineties as an evolution of existing quality systems, environmental management and industrial safety. As background of embedded systems MRP (Manufacturig Resource Planning), MAP (Manufacturig Automation Protocol) and TOP (Technical Office Protocol) are counted. Objetive: The aim of the project focuses on identifying the relationship and existing points of convergence between ISO 9001: 2008, 14001: 2004 and OHSAS 18001: 2007 for the implementation of the integrated management system (IMS) in civil engineering companies with their economic activity in the Colombian construction sector. Methodology: An analysis of the structure of each of the three standards under study is performed and the points of convergence and divergence are identified in order to find a main structure that works for managers of construction companies as input to make decisions to implement integrated management systems. Results: As a main product is obtained a comparative table that allows articulate the three standards to further characterize under the Deming cycle, or PDCA (Plan-Do-Check-Act). Convergence and complementarity between standards issues are identified and the minimum documentary platform for integrated management system is established. Conclusions: The integrated construction companies systems are alternative productive and organizational operation characteristics that give visibility, credibility, competitiveness and profitability for these companies to compete in dynamic business scenarios and ensure compliance with contractual commitments under highly demanding global marketsPalabras clave: Calidad, Ingeniería civil, Normas, Medio ambiente, Salud ocupacional, Seguridad industrial, Sistema de gestión

Este artigo pretende pensar a escola como um espaço de tolerância e de respeito, que propicie o desenvolvimento de uma cultura democrática, de maneira que o seu funcionamento estimule a participação de todos na tomada de decisões. Isso parece ser utópico e não fazer parte da vontade política das lideranças do mundo globalizado e, sobretudo, capitalista. O trabalho escolar realizado na gestão, na maioria das vezes, perde o sentido de espaço de troca, de construção e de relação social, e é encarado apenas como fator de emancipação econômica, moeda de troca, o que é ilusório, pois a remuneração oferecida de acordo com o mercado não atende, há muito tempo, às reais necessidades. Desse modo, objetiva-se discutir a gestão escolar diante de um contexto histórico na América Latina, ditado por um Estado Neoliberal que não valoriza a Educação Escolar e que entende o trabalho enquanto venda de força produtiva por um salário no final do mês, e não enquanto produção da existência humana. Education and school management in Latin America: history, challenges and opportunities AbstractThis article intends to think the school as a place of tolerance and respect that fosters the development of a democratic culture, so that its operation encourages the participation of all in decision making processes. This seems to be utopian and not part of the political will of the leaders of the globalized and - especially - capitalist world. The work performed in school management, in most cases, loses the sense of space of exchanges, of social construction and relationship, and is seen only as a factor of economic emancipation and currency exchange, which is illusory because the compensation offered according to the market no long meets the real needs. This way, our goal is to discuss the school management before a historical context in Latin America, which is dictated by a neoliberal state that does not value the school education and that understands labor as sale of productive force for a salary at the end of the month and not as production of human existence.Keywords: School Management in Latin America.
