In Legehennenbeständen wurde die Schutzwirkung von vier Impfprogrammen, die der Zentralverband der Deutschen Geflügelwirtschaft e.V. empfiehlt und einer Impfung nach der Hühner-Salmonellen-Verordnung untersucht. Unterschiede in den Impfschemata konnten unter den gewählten Versuchsbedingungen nicht festgestellt werden. Eine Impfung gegen Salmonellen garantiert keine vollständige Elimination des Erregers, sondern eine Reduktion der Besiedelung der Organe sowie der Ausscheidung und der Eikontamination. Auch eine zusätzliche Impfung mit Inaktivatimpfstoffen erbrachte keinen effektiveren Schutz vor Salmonella Enteritidis und Salmonella Thyphimurium. Die Schutzwirkung einer Impfung ist am besten, wenn die Salmonellen-Exposition gering ist.

Abstract:
Atualmente, as atividades do agronegócio necessitam, como todas as demais áreas, de soluções inovadoras que potencializem as mais diferentes demandas do negócio; a agricultura de precisão é um caminho que vem se mostrando eficiente na tomada de decisão. Nos dias atuais, a aplicação do veículo aéreo não tripulado- VANT ou também conhecido como aeronave remotamente pilotada- ARP vem se mostrando uma crescente ferramenta de inserção dentro deste contexto e aplicação. A tomada de decisão do agricultor, seja ele de pequeno, médio ou grande porte, pode ser auxiliada com o uso de equipamentos e softwares que vêm se tornando uma prática usual tanto nas atividades da agricultura como em outras tantas, isso devido a sua fácil aplicação, baixo custo e grande possibilidade de aplicações nas diferentes atividades do agronegócio. Os veículos de asas rotativas são, nesse contexto de uso, atrelados a aplicativos específicos, uma solução eficaz na gestão de diferentes culturas e atividades no agronegócio. Os resultados observados com os voos realizados, com as coletas de imagens, bem como o mapeamento de culturas e propriedades rurais se mostraram satisfatórios ao longo da pesquisa, tanto na forma de controle de voo manual quanto no modo autônomo de coleta de dados. Outro fator que possibilitou a pesquisa foi o uso de aplicativos de imagem e rota de voo, possibilitando cumprir os diferentes objetivos propostos na pesquisa.
Currently, the agribusiness activities require, as all other areas, innovative solutions that empower the most different demands of business; the precision agriculture is a path that has been showing efficient decision-making. Nowadays, the application of unmanned aerial vehicle UAV - or also known as aircraft remotely piloted - ARP has been showing a growing insertion tool within this context and application. The farmer\'s decision making, be he small, medium or large, can be aided with the use of equipment and software that has become an usual practice both in the activities of agriculture as in others, that due to its easy application, low cost and great possibility of applications in the different activities of the agribusiness. Rotary wing vehicles are, in this context of use, tied to specific applications, an effective solution in different management cultures and activities in agribusiness. The results observed with the flights taken, with collections of images, as well as the mapping of cultures and rural properties have proven satisfactory throughout the research, both in the form of manual flight control mode of collection of data, another factor that enabled the research was the use of imaging applications and flight path, in this way, it was possible to accomplish the different objectives proposed in the research.

Abstract:
Food systems are facing increasing pressure to adapt to the local, regional and global implications of the climate crisis while reducing the environmental impacts of food production and retaining their competitiveness on increasingly connected agri-food markets. Many suggested aspects of a more resilient, sustainable model of food production are directly linked to decisions made on individual farms. However, there are known social-ecological traps that limit farmers’ capacity to break away from unsustainable paths. This thesis investigates the impact of trap dynamics on the incidence of sustainability transitions on Finnish farms – for example, transitions from animal to plant agriculture, or from monoculture to crop diversity. I use national tax records and interviews with regenerative farmers to identify patterns and circumstances that preclude farmers’ ability to carry out sustainability transitions, and to describe strategies used by regenerative farmers to enhance their agency and avert traps. My findings indicate that rigid governance and market structures, an increasing burden of debt and intensifying ecological pressures converge to create, sustain and exacerbate social-ecological traps. Finally, this thesis suggests that the existence of farm-level traps may hamper attempts to address food system lock- ins across scales, diminishing the system’s capacity to respond to shocks and changing circumstances.

Abstract:
En aquest estudi s'analitza l'evolució del sector vitícola de Menorca durant els segles XVIII, XIX i XX confrontant-lo amb la del sector ramader.
En el segle XVIII es constata un avanç de la producció vinícola, gràcies a l'estímul de l'augment de la població. No obstant això, aquesta disminueix a partir de 1830, quan l'economia insular sofreix una severa depressió. L'excedent vinícola generat ocasiona una forta caiguda dels preus. Així, quan el oídium assoli la illa a partir de 1852, s'experimentarà una arrencada massiva de vinyes.
Paral·lelament augmenta el pes de la ramaderia bovina, amb una importància creixent de la producció formatgera, i que, quan a la dècada de 1960 desaparegui el cultiu del blat, es convertirà en l'únic sector agrari de la illa. Tanmateix, i malgrat l'augment dels rendiments esdevingut a partir de 1950, la ramaderia presentarà una capacitat de generació de renda decreixent.
En este estudio se analiza la evolución del sector vitícola de Menorca durante los siglos XVIII, XIX y XX confrontándolo con la del sector ganadero.
En el siglo XVIII se constata un avance de la producción vinícola, gracias al estímulo del aumento de la población. Sin embargo, ésta disminuye a partir de 1830, cuando la economía insular sufre una severa depresión. El excedente vinícola generado ocasiona una fuerte caída de los precios. Así, cuando el oídium azote la isla a partir de 1852, se experimentará un arranque masivo de viñedo.
Paralelamente aumenta el peso de la ganadería bovina, con una importancia creciente de la producción quesera, y que, cuando en la década de 1960 desaparezca el cultivo del trigo, se convertirá en el único sector agrario de la isla, pero que, pese al aumento de los rendimientos acaecido a partir de 1950, presentará una capacidad de generación de renta decreciente.
This study examines the evolution of the vineyard in Minorca during the XVIII, XIX and XX centuries, and compares it with that of the livestock sector.
In the eighteenth century there is a breakthrough in wine production, thanks to the stimulus of increased population. However, it decreases from 1830, when the island economy suffers a severe depression. The wine surplus generated causes a sharp drop in prices. Thus, when the oidium plagued the island from 1852, it will experience a massive boot vineyard.
In parallel, the weight of cattle increases, with a growing importance of cheese production, and which, when in the 1960's the crop of wheat disappear, it will become the only agricultural sector of the island. However, and despite the rise in yields occurred after 1950, it will present a declining capacity of income generation.

Abstract:
English pastoral husbandry has been largely neglected by previous historians. It is generally agreed that the mid-eighteenth century saw a revolution in breeding practices, moving livestock husbandry from hopeless confusion to a controlled, 'scientific' selection for marketable traits. The academicians, mostly economic historians, who have developed this model of pastoral history rely heavily upon farming manuals dating from the fifteenth to the eighteenth centuries for evidence of the changes they claim to perceive. Agricultural manuals are complex literary documents. However, in the current historiography, the manuals are quoted as simple records of contemporaneous agricultural practice, the intricacies of authorship, audience and motive for publication being almost entirely ignored. A critical survey of the manuals which deal with pastoral husbandry beginning with the thirteenth, rather than the fifteenth, century reveals flaws in the use which has been made of the manuals and, therefore, in the conclusions which have been drawn from them. In order to accomplish a reconsideration of English pastoral husbandry, it is necessary to reincorporate the extant medieval farming manuals and to examine all didactic agricultural texts as representative of a single genre. Discussion of livestock husbandry was carried out in terms of generation and nutrition of animals. Therefore, any intimations of procedural changes or scientific influence upon breeding and feeding in the discussions of manuals which deal most extensively with pastoral husbandry should be noted as of particular interest. Finally, the manuals must be considered within a social context. It is here that the interaction of science and agriculture becomes particularly important, though as a tool for understanding the manuals as documents rather than solely as the motor for late eighteenth-century changes in livestock husbandry. Such an analysis reveals an amazing continuity of actual information in the agricultural manual genre. There are no changes in the depictions of practices of breeding and feeding. However, especially in the late seventeenth and eighteenth century texts, a preoccupation with attracting the attention of institutional science, particularly the Royal Society, emerges as a new trend. Yet there is no indication in the textual record that livestock husbandry was ever affected by 'Natural Philosophy'. Far from simply recording contemporary practice, agricultural manuals, especially those which expressed a desire to ally with institutional science, reveal themselves more as vehicles for their authors' social aspirations than as exemplars of agricultural practice. Once this is recognized, the prevailing models of pastoral husbandry lose credibility. Eighteenth-century animal breeding was no more nor less 'scientific' or intellectually sophisticated than preceeding breeding programs. In short, the use of farming manuals to corroborate economic models of agrarian development has been, at best, somewhat spurious. Studying livestock husbandry and its relationship to institutional science in medieval and early modern England can be peculiarly helpful in assisting to rectify this error.

Full text
Abstract:
La Syrie centrale connaît au début de la période byzantine, et en particulier au Ve et au VIe siècle, un fort mouvement d’expansion des sédentaires vers l’est, qui coïncide avec une importante mise en valeur de ces nouveaux territoires. Comme pour d’autres régions de Syrie et du Proche-Orient à la même époque, un optimum climatique – pourtant déclinant – semble avoir permis la conquête et l’exploitation agricole de nouveaux terroirs dans une zone marginale qui n’avait jusqu’alors connu qu’une occupation sédentaire ponctuelle. La Syrie centrale est caractérisée par des milieux aux potentiels agronomiques très différents, souvent imbriqués. Le peuplement et la mise en valeur y sont soumis à la double contrainte de l’aridité climatique et édaphique, qui s’exerce avec une prégnance croissante vers le sud et l’est. Ces conditions, qui s’améliorent localement à la faveur de niches écologiques, ont permis à des politiques de mise en valeur et à des économies distinctes, souvent complémentaires, de voir le jour.Dans une région où les cités paraissent en grande partie absentes, l’économie repose d’abord sur les villages et sur quelques bourgs qui possédaient manifestement une orientation commerciale spécifique. Aux côtés des agglomérations, et souvent d’autant plus nombreux que les conditions d’implantation sont délicates, des fermes et des monastères s’affirment comme des acteurs économiques apparemment indépendants et souvent prospères. Des entités géographiques relativement homogènes ont donné lieu à une répartition des différentes formes de peuplement et à des économies microrégionales spécifiques. Si l’agriculture vivrière reste la règle, il semble bien cependant qu’on observe une spécialisation locale des productions : culture du blé et accessoirement plantations à l’ouest, oléiculture et peut-être viticulture dans les plateaux basaltiques du nord-ouest et vraisemblablement un élevage spéculatif, qu’on doit probablement attribuer à des populations sédentaires, dans les secteurs sud et est
In Late Antiquity, especially between the 5th and 6th centuries, Central Syria witnessed a strong expansion of sedentary settlements eastward, which coincided with a significant agricultural development of these new territories. As for other areas in Syria and Near-East at the same period, a waning climatic optimum seems to have allowed byzantine population to settle down in marginal areas which barely experienced hitherto sedentary occupation and farm nearly unbroken lands.Central Syria is made up of various landscapes, sometimes deeply nested, with contrasted agricultural potential. Settlements and agricultural exploitation are affected by an increasingly significant climatic and edaphic aridity eastward and southward. These conditions, which may locally improve thanks to ecological niches, enabled specific and often complementary substance strategies to develop.In a country whence cities are virtually absent, villages and a few market towns seem to be at the very root of the regional economy. Along with agglomerations, scattered habitats – namely farmsteads and monasteries –, more numerous under heavy bioclimatic constraints, would appear as independent and apparently prosperous economic players.Homogeneous geographic areas led to specific settlement patterns and different economic orientations. Food-producing agriculture remains the rule, but a local productive specialization may be noticed: mainly wheat production and incidentally plantations westward, olive-growing and maybe wine-growing as well in the north-west basaltic plateaus and presumably speculative livestock exploitation eastward and southward, probably mostly due to sedentary populations

Abstract:
Den domesticerade kaninen (Oryctolagus cuniculus) är idag ett vanligt sällskapsdjur världen över. Sällskapskaniner framhålls som det tredje mest populära sällskapsdjuret i Sverige, efter hund och katt. Trots detta behandlar endast en mycket liten andel av den övergripande forskningen inom ämnet hälsa- och välfärd just kanin. Den här studien har undersökt inverkan på sällskapskaninens välfärd av kaninägare med eller utan tidigare erfarenhet, sjukdomsbild, samt kaninägares preferenser - och om detta är faktorer som påverkar sällskapskaninens välfärd i Sverige. Studien genomfördes som en enkätundersökning, besvarad av 147 deltagare bosatta i Sverige. Enkäten publicerad i nätverkstjänsten Facebook och fanns tillgänglig under tidsperioden 23:e April - 7:e Maj, 2021. Mer än 50 % av deltagarna saknade erfarenhet och kunskap om kaniner innan de skaffade sin första kanin. Över 37 % höll sina kaniner ensamlevande, och mer än 21 % inhyste sina kaniner i bur. Behovet av veterinärvård utgjordes totalt av nästan hälften av kaninerna, och de kaniner som hölls inomhus eller frigående hade störst behov. Det fanns en skillnad i behovet av veterinärvård hos olika raskategorier, där kategorin små raser var högst representerad. Antalet kaniner som drabbades av olika typer av hälsorelaterade problem varierade, men sjukdomar kopplade till avelsrelaterad problematik utgjordes av nästan 1/3 av alla sjukdomar. Den vanligaste raskategorin att hålla var dvärgraser som hölls av nästan 60 % av alla deltagare, och den vanligaste orsaken till att välja just den raskategorin utgjordes av dess storlek. Den här studien visade att det finns faktorer i kaninägarens djurhållning som kan kopplas till sällskapskaninens välfärd i Sverige. Avgörande parametrar till detta har lyfts fram som kaninägarens erfarenhet och kunskap om kaniner, hållning och inhysning, samt val av raskategori.

The domesticated rabbit (Oryctolagus cuniculus) is today a common pet worldwide. Pet rabbits are highlighted as the third most popular pet in Sweden, after dogs and cats. Despite this, only a very small proportion of the overall research in the subject of health and welfare deals with rabbits. This study has examined the impact on the companion rabbit's welfare of rabbit owners with or without previous experience, disease picture, and rabbit owners' preferences - and whether these are factors that affect the companion rabbit's welfare in Sweden. The study was conducted as a survey, answered by 147 participants living in Sweden. The survey was published in the network service Facebook and found available during the period 23 April - 7 May, 2021. More than 50% of the participants lacked experience and knowledge about rabbits before acquiring their first rabbit. Over 37% kept their rabbits alone, and more than 21% housed their rabbits in cages. The need for veterinary care accounted for a total of almost half of the rabbits, and the rabbits kept indoors or free-running were most in need. There was a difference in the need for veterinary care in different breed categories, where the category small breeds was most represented. The number of rabbits suffering from various types of health-related problems varied, but diseases linked to breeding-related problems accounted for almost 1/3 of all diseases. The most common breed category to keep was dwarf breeds held by almost 60% of all participants, and the most common reason for choosing that particular breed category was its size. This study showed that there are factors in the rabbit owner's animal husbandry that can be linked to the companion rabbit's welfare in Sweden. Decisive parameters for this have been highlighted as the rabbit owner's experience and knowledge of rabbits, posture and housing, as well as the choice of breed category.

Abstract:
The present study on “the use of slang among the students of the Higher Institute of Agriculture and Animal Husbandry (I.S.A.E)” attempts to examine how and why the students use slang terms to commutate various issues. The research focuses on slang used by I.S.A.E students because most studies have dealt with Rwandan regional dialect, but in my knowledge none of them has been conducted on the slang terms used by the students of I.S.A.E. In conducting this research, I intended to give my contribution by producing a study on slang in the context of Rwanda and particularly on students’ slang. The research begins with different definitions of slang and the theoretical approach is discussed afterwards. The present study is empirical. Both qualitative and quantitative methodologies are employed. The data was elicited from I.S.A.E students, staff and five ‘outsiders’ using diverse methodological tools such as questionnaire forms, focus-group interviews and participants. On one hand, the questionnaire survey was used mainly to gather lists of slang words. On the other hand, focus-groups and participant observations were used to reach a deeper ‘ethnographic insight’ into the meanings and contexts of usage of the slang. The current study focuses primarily on the morphological and semantic etymology of the 77 selected slang terms. The study indicated that the slang terms found in the speeches of the students of I.S.A.E are the results of various morphological processes such as coinage, borrowing, clipping, compounding and acronyms.

The purpose of this study is to explore the impact of transfer pricing on the effective tax rate of listed farms, forestry, fishery and animal husbandry companies in mainland China.It is rare to find the literature on the effective tax rate of listed farms, forestry, fishery and animal husbandry companies in mainland China. The parent company of the foreign company or the triangle trade, using the information of the listed farms, agriculture, forestry, fishery and animal husbandry companies in mainland China, using the transfer The pricing is used as a method for corporate tax avoidance. The empirical results show that the transfer pricing has a negative relationship with the effective tax rate. For the overall business performance of the company, since the reform and opening up over the years, Taiwanese businessmen who have worked hard in China Using the tax laws promulgated by the State Administration of Taxation of the People's Republic of China to save taxes in a reasonable and legal manner without tax evasion, such as setting up an OBU company overseas through a tax haven, and then passing the domestic after-tax surplus through the relationship enterprise. The transaction, transfer to the tax-free area or the 10% reduction of income tax expenses in the free trade zone has reached the purpose of saving taxes. This profit model, commonly known as "triangular trade", is a widespread tax avoidance by Taiwanese businessmen in various ways in mainland China. But now, on March 17, 2017, China has officially issued the "Special Tax Investigation Adjustment and Mutual Negotiation Program". The Administrative Measures and (No. 6 Announcement or Administrative Measures) were implemented on May 1 as the target for a comprehensive review of the pricing of transfer pricing tax in mainland China. This study used a sample of mainland China companies from 2007 to 2016. The results showed that mainland Chinese companies did use transfer pricing to allow companies to achieve effective tax rates. This conclusion is consistent with previous scholars' experts and research papers and expectations. It shows that the transfer price has a negative relationship with the effective tax rate.

Having undergone the storm of food safety crisis, consumers are acting in an evolutionary way in the post era of food safety. It is worthy of investigation under the rapidly changing consuming style how consumers can be convinced that all the eggs produced by egg industry in Taiwan are good for health, and what kind of marketing strategies can be used to respond to this severe market. This thesis is based on a case study of a company to investigate the success key factors in related to its markeing and management strategies. This thesis employs semi-structured interviews and Kotler 6P theory to analyze the marketing strategy of this company. Finally, the key success factors of this company are concluded. This thesis concludes the analysis and gives its strategic suggestions as the following. The key success factors are the quality of the main commodity eggs has been recognized by the market, niche commodity organic fertilizer has great potential,upstream and downstream integration, with cost reduction, foundr’s vision is clear, and positioning and fulfilling social responsibilities. That results in an wider access to trade marketing and thus leads to an increasing amount of sales.

Animal husbandry is the longest way for people to produce food. Due to the increase in food required for the global population increase, the number of livestock farming and the density of stocking have also increased, and the situation of environmental pollution has gradually increased. In order to improve the environment of livestock farms and reduce air pollution, this paper uses temperature and humidity sensors and air quality sensors to sense the environment and air quality of livestock farms. By controlling fans, sprinkler systems, negative ion generators, and ozone generators, the goal of improving livestock environment and reducing air pollution is achieved. This study is based on the Arduino Uno R3 evaluation board. The DHT11 temperature and humidity sensor and the MQ-135 air quality sensor are used to sense the environmental status of the livestock farm. By controlling fans, sprinkler systems, negative ion generators and ozone generators, we can improve the environment and reduce pollution in livestock farms. By using ESP-01 WiFi module, the environmental monitoring data and the controller status can be uploaded to the cloud server. Users can observe the environmental monitoring data and the controller status of the livestock farm through the web browser of various smart devices. This study constructs an agricultural Internet of Things for animal husbandry, which can sense and improve the environment and pollution of livestock farms, and can observe the state of livestock farms through the smart device.

The compost of livestock excreta is a good organic material, and swine waste not only contains trace elements like copper and zinc to improve mechanical, biological and chemical qualities of soil, but also can save the cost of chemical fertilizer. It is the best treatment to recycle those swine waste as compost, but it may pollute soil and environment if the compost contains excess copper and zinc accumulating in soil. This study investigates the change of soil heavy metal effected by added swine waste compost in Kimen country, where has poor soil qualities and distributed unevenly rainfall. Sampling 11 farmland soils which added its own swine waste as fertilizer to analyze both soil quality, feed and wastes (included sludge and wastewater after solid-liquid separated).Sampling method was drawing one hectare as one unite and sampling soils of five spots with five meter range around the center of one unite, and mixing five samples to analysis. Analyzing results show that farmland soil samples’ saturated adsorption of copper and zinc were 45 mg/kg and 100 mg/kg, which were lower than the monitor value of crop farms (copper:120 mg/kg, zinc:260 mg/kg); maximum copper and zinc concentration of farmland wastes were 100 mg/kg and 200 mg/kg, which related to the copper and zinc contains within feeds, fit the tolerance standard of organic fertilizer (copper:100 mg/kg, zinc:800 mg/kg). Among these sampling farmlands, soil pH value were from 3.8 to 6.7 all higher than soil fertility quality pH 2.69 requested by Kimen country in 2002, which showed adding swine waste into soil can buffer soil pH value. Adding swine waste may also polluted soil with heavy metal, soils in this study were lightly polluted although the heavy metal contains lower than monitor value of crop farm.

In Pingtung and Yunlin, animal husbandry is developed and intensive, and irrigated farmland by livestock wastewater is gradually becoming the normality. Due to ingredient of animal feed containing copper and zinc, long-term irrigation may cause potential pollution to the soil, so this study for soil and irrigation ditches of the fields near the intensive irrigation and drainage areas of Pingtung (intensive irrigation and drainage areas)and Yunlin (irrigation), sampled the soil, sediment and irrigation water individually, and the basic characteristics of the soil were analyzed after irrigation, compared with the two different irrigation methods to the differences of soil properties, discussion on the effect of livestock wastewater to the soil quality. The results showed that the concentrations and variability of ECs, copper, zinc and CEC of Yunlin area were lower than Pingtung, which the TOC was in the appropriate range, due to Yunlin area have the fixed irrigation of livestock wastewater, the soil quality is not affected by the rainy and dry season easily, and the crop have short tillage is required to turn over to increase soil porosity in order to pollutants are diluting to the bottom soil. It’s worth mentioning the problem of ammonia nitrogen in the groundwater of Yunlin. Due to animal husbandry waste water of Pingtung area have no limits for irrigation requirement and area of land, most of the fruit trees in Pingtung and which dry farmland without plowed soils result in the pollutants relatively accumulated in the soil surface easily and the water dilution of the rainy and dry season had a great effect on soil quality. In the Pingtung area, copper and zinc of irrigation water were much lower than the irrigation water standard but which some of the soil was higher than the monitoring value, compared with water and soil samples contain the copper and zinc of the Pingtung area, found that copper and zinc deposit in the sediment along with the time and gravity, inferred for the long-term irrigation of livestock wastewater or application of chemical fertilizers contained both copper and zinc adsorbed and accumulated in the sediment. For intensive irrigation and drainage areas and irrigation from animal husbandry wastewater, Yunlin area have the fixed irrigation of livestock wastewater and the soil quality is not affected by the rainy and dry season easily, and the crop have short tillage is required to turn over to increase soil porosity result in pollutants are diluting to the bottom soil, which conforms to the soil quality standard and suitable environment for crop growth.

Both humans and dogs are integral in sheep production systems; however, which is more aversive to sheep, or indeed, whether either causes significant stress, has not been shown experimentally. The aim of this thesis was to examine some behavioural and physiological responses of domestic sheep to the presence of humans or dogs. An arena test was used to measure the relative aversion of sheep to the presence of a human or dog, as well as to elucidate differences in the responses of flocks at the University of Western Australia (UWA) which were putatively selected for differences in fearfulness. A Y maze preference test was used to 'ask' sheep whether they preferred a human shaking a rattle or a barking dog. In both tests, adrenocortical responses were measured concurrently to support the interpretation of behaviour. The presence of a human or dog in the arena elicited significantly more avoidance and vigilance behaviour and less exploration than did the presence of a control object. However, the dog elicited significantly more of this fear-related behaviour, and significantly larger adrenocortical responses than did the human. Sheep also expressed a clear preference for a human shaking a rattle over a barking dog in the Y maze test and exhibited larger adrenocortical responses to the dog than to the human in the Y maze facility. The UWA flocks differed in their expression of locomotor and vocal activity; MA sheep were more active/vocal than the other flocks, not only in the presence of the human but also with the box or dog. MA sheep expressed less avoidance and vigilance and more exploration than the other flocks in the presence of the human and exhibited significantly lower plasma cortisol concentrations than LA sheep after exposure to the human (10-min sample). However, there were no inter-flock differences in fear-related behaviour or adrenocortical responses when the flocks were presented with the box or dog. The results do not support the notion that the UWA flocks have been selected for differences in a consistent predisposition to react fearfully. The adrenocortical responses measured in these studies were only moderate in magnitude and duration, with peak plasma cortisol concentrations 2-3 times higher than pre-treatment values, and all concentrations returning to pre-treatment levels within one hour of the start of treatment. If these observations are confirmed in practical situations, the presence of humans and dogs during routine handling should cause little concern on the basis of animal welfare. However, limiting the presence of dogs in certain situations (e.g. before slaughter) may reduce stress in domestic sheep. Significant methodological developments in this research include the use of multivariate statistical techniques to analyze arena behaviour, the concurrent measurement of adrenocortical and behavioural responses in the arena and Y maze tests, and the explicit testing of the effects of individual lateral biases on choice behaviour in a Y maze test. Future studies should measure sheep stress responses to the presence of humans and dogs in practical situations.

Abstract:
The Salado region of Argentina covers 9.5 million ha, is located in the centre-East of the Buenos Aires Province, and concentrates about 6.9 million cattle. Cow-calf systems are predominant in the area. A simulation model was developed with the purpose of assisting in the design and evaluation of cow-calf systems in the Salado Region. The model was designed to produce long term simulations of the dynamic interactions between herd structure, climatic variation and farm management over periods of several decades using daily weather data, real or simulated. Existing models were used to describe soil, pasture and animal components of the farm, linked with management actions in a dynamic framework. The model was driven by decision rules entered by the user, which allowed the representation of management options that respond to changing farm conditions according to a predetermined policy. An object-oriented approach (OOA) was used in the design and implementation of the model. In the OOA, objects in the real world (e.g. cows, paddocks) are represented as objects in the computer program. The simulation of individual cows and individual paddocks made it possible to distribute feed resources flexibly among animals and provided many other points of flexibility in management strategies. The management strategies simulated in trying to improve cow-calf systems in the Salado region were based on Reserva 6, an experimental cow-calf farm located at the INTA-Balcarce Experimental Station. Every spring-summer, 30% of the area is devoted to make low quality hay (by cutting at high herbage mass), most of which is destined to provide maintenance feed for pregnant adult cows in winter. Cows are kept on a small paddock from weaning (March) to calving (August-September), during which time they receive 6-9kg DM of hay per day. A set of decision rules was developed to represent (on a 100ha farm) the management applied in Reserva 6 and, using this as a base system, a series of simulation experiments was conducted. Firstly, three preliminary experiments, aimed at gaining insight into the system and testing the model, were carried out. In the first of these, the effect of delaying the breeding season 15 and 30 days was analysed. The model was run over 30 consecutive years using a real weather sequence, 1970-2000, from INTA-Balcarce, for each scenario. It was found that, when the appropriate management variables (i.e. weaning and sale dates) were adjusted accordingly, changing the calving period had little effect on the productivity of a cow-calf system. In the second experiment, the dynamic consequences of three different heifer replacement policies on the production outcomes of the system were explored. The policies produced different patterns of oscillations in key farm outputs as a result of periodic behaviour in the age structure of the herd, and the differences between strategies were shown to be dependent on the environmental variability being simulated. The third experiment analysed different policies for hay use during the autumn-winter period, including a control strategy in which no hay was harvested or used. The results suggested that, provided hay was utilized on the farm, the pattern of use did not make much difference to liveweight production. Secondly, the long term performance, in terms of annual liveweight sold, of a range of hay quantity-quality combinations was compared. Each policy was simulated across a range of cow numbers (170 to 350, cows plus heifers in a 100ha farm) and was replicated 20 times. Each replication consisted of 50 years of random weather sampled from the real sequence (1970-2000). The benefit of using hay and the contrasts between the effects of different haymaking strategies on animal outputs increased as the cow numbers increased. The long term analysis suggested that the liveweight production of cow-calf farms, under a calendar-based haymaking policy like that followed in Reserva 6, would be maximized by harvesting 40-50% (but not more) of the total farm area and aiming to harvest hay at medium herbage mass (therefore medium quality). Therefore, the policy currently followed in Reserva 6 of allocating 30% of the farm to haymaking could be considered as conservative, and its productivity might be increased by making hay at lower herbage mass. Thirdly, the possible advantages of incorporating flexibility into the haymaking policy used in Reserva 6 were evaluated using the same experimental design. The results indicated that controlling haymaking in a flexible fashion, basing the decisions of closing, releasing and cutting paddocks on a simple pasture budget, would give the system productive advantages (i.e. increases in productivity and reductions in variability) in relation to a calendar-based approach. Using a flexible haymaking policy allows the manager to make more hay than required for the next winter, providing a buffer for the system. A flexible haymaking policy permitted significantly greater levels of herbage utilization by making large amounts of hay without negative effects on the carrying capacity of the system. A preliminary analysis of risk and costs highlighted major advantages in using hay in cow-calf systems, especially when a flexible approach to haymaking is implemented.

Abstract:
This thesis set out to examine the effect of maternal undernutrition and exposure to stressors between pregnancy day 50 to 100 and 100 to 147 of pregnancy on the ewe and her lamb. The long-term effects of these stressors during pregnancy on lamb growth, plasma cortisol response to a stressor, metabolism, behaviour and future reproductive success were examined. Mid-pregnancy shearing The component of mid-pregnancy shearing that causes the increase in lamb birth weight is unknown. It was hypothesised that the increase in lamb birth weight was due to the stress response of the ewe to shearing. This work examined the effect of a range of stressors at approximately day 80 of pregnancy. These stressors included yarding, crutching and sham-shearing that may be components of the shearing procedure that produce a stress response. In addition, repeated stressors between day 74 and 106 of pregnancy including isolation, sham-shearing and exogenous cortisol injection were used to examine the role of a longer-term stress response on lamb birth weight. Mid-pregnancy shearing has consistently resulted in an increase in lamb birth weight, however all the other stressors investigated had no effect. Therefore, the hormonal stress response of ewes to shearing was unlikely to be the cause of the increase in lamb birth weight. Mid-pregnancy shearing also resulted in minor changes in ewe and lamb behaviour 12 to 24 h after birth. Shearing during pregnancy had no effect on the cortisol response of ram lambs to handling or castration however differences were observed between singleton- and twin-born lambs. Ewe nutrition during pregnancy Ewes mildly undernourished in between days 70 and 107 of pregnancy that were then provided with adequate nutrition between days 108-145 of pregnancy gave birth to lambs with similar birth weights as ewes well-fed during both periods. Therefore the effects of undernutrition on lamb birth weight can be minimised if undernutrition can be limited to the earlier period (day 70-107 and 108-147 of pregnancy). Mild undernutrition in both periods (day 70 – 145 of pregnancy), resulted in lambs that were lighter and that exhibited behaviours associated with a greater ‘drive’ to maintain contact with their dam than lambs born to ewes well-fed during the same period. This suggests that even mild undernutrition in both mid- and late- pregnancy should be avoided. The effect of maternal nutrition and lamb litter size on the behaviour of female offspring was examined at 1 and 2 years of age. Litter size had no effect on ewe behaviour at 1 year of age however at 2 years of age twin-born ewes had higher maternal behaviour scores than triplet-born ewe lambs. Nutrition of the maternal grand dam during pregnancy had only a minor effect on the behaviour of female offspring at 1 year of age and no effect on maternal behaviour at 2 years of age.
