This research is to determine the features of identification of products of the slaughter of nutria while post-slaughter veterinary-sanitary control, to assess the slaughtered yield, to study the peculiarities of the chemical and biochemical composition of the products of the slaughter of nutrias. This will allow, under the conditions of import substitution, to extend the source of raw materials for the production of sausage products and assortment of meat ready-to-cook foods. This paper represents the results of the veterinary and sanitary assessment of nutria meat as a prospective raw material for the meat processing industry in Ukraine. The peculiarities of identification of slaughter products of nutria are determined by the presence of fat deposits, rounded form lipoma, and the structure of internal organs while post-slaughter veterinary and sanitary control of nutrias’ carcasses. It is proved, nutrias have been shown to have a sufficiently high slaughter yield of 57.5 ± 2.3% as compared to rabbits. It has been proven that nutria has a fairly high lethal yield compared to a crawl. The difference in the slaughter rate of female and male species was negligible and was 4.5 ± 1.4%. Nutrias’ Meat Index is 4.9 ± 0.7. The high content of flesh on the spinal-chest and the thigh makes it possible to recommend these parts to produce portion (pieces) semi-finished products According to physicochemical composition nutria meat is characterized by an increased content of moisture (90.27 ± 2.18%), high content of protein (20.82 ± 1.15%) and low content of fat (8.34 ± 0.71%), which makes it possible to attribute this kind of meat to dietary

Full textAbstract:
The nutria (Myocastor coypus) is an invasive alien species that have had major adverse effects on biodiversity and the agricultural economy in wetland habitats. Since 2014, the Ministry of Environment in South Korea has been carrying out the Nutria Eradication Project, and we investigated nutria distribution and genetic diversity of nutria populations in South Korea. We estimated that 99.2% of nutria habitats are in the mid-lower Nakdong River regions. To further analyze the genetic diversity in eight major nutria populations, we performed a genetic analysis using microsatellite markers. Genetic diversity levels of the eight nutria populations in South Korea were relatively lower than those in other countries. The probability of migration direction among nutria populations was predicted from genetic distance analysis. Genetic structure analysis showed little difference among the nutria populations in South Korea. These results suggest that nutrias in South Korea originated from a single population. Our results provide important data for establishing management strategies for the successful eradication of nutria populations in South Korea, as well as in other countries with alien invasive species.

Full textAbstract:
The emergence and spread of antibiotic-resistant Aeromonas spp. is a serious public and animal health concern. Wild animals serve as reservoirs, vectors, and sentinels of these bacteria and can facilitate their transmission to humans and livestock. The nutria (Myocastor coypus), a semi-aquatic rodent, currently is globally considered an invasive alien species that has harmful impacts on natural ecosystems and carries various zoonotic aquatic pathogens. This study aimed to determine the prevalence of antibiotic-resistant zoonotic Aeromonas spp. in wild invasive nutrias captured in Korea during governmental eradication program. Three potential zoonotic Aeromonas spp. (A. hydrophila, A. caviae, and A. dhakensis) were identified among isolates from nutria. Some strains showed unexpected resistance to fluoroquinolones, third-generation cephalosporins, and carbapenems. In carbapenem-resistant isolates, the cphA gene, which is related to intrinsic resistance of Aeromonas to carbapenems, was identified, and phylogenetic analysis based on this gene revealed the presence of two major groups represented by A. hydrophila (including A. dhakensis) and other Aeromonas spp. These results indicate that wild nutrias in Korea are a potential reservoir of zoonotic and antibiotic-resistant Aeromonas spp. that can cause infection and treatment failure in humans. Thus, measures to prevent contact of wild nutrias with livestock and humans are needed.

Cryptosporidium spp., common parasites of vertebrates, remain poorly studied in wildlife. This study describes the novel Cryptosporidium species adapted to nutrias (Myocastor coypus). A total of 150 faecal samples of feral nutria were collected from locations in the Czech Republic and Slovakia and examined for Cryptosporidium spp. oocysts and specific DNA at the SSU, actin, HSP70, and gp60 loci. Molecular analyses revealed the presence of C. parvum (n = 1), C. ubiquitum subtype family XIId (n = 5) and Cryptosporidium myocastoris n. sp. XXIIa (n = 2), and XXIIb (n = 3). Only nutrias positive for C. myocastoris shed microscopically detectable oocysts, which measured 4.8–5.2 × 4.7–5.0 µm, and oocysts were infectious for experimentally infected nutrias with a prepatent period of 5–6 days, although not for mice, gerbils, or chickens. The infection was localised in jejunum and ileum without observable macroscopic changes. The microvilli adjacent to attached stages responded by elongating. Clinical signs were not observed in naturally or experimentally infected nutrias. Phylogenetic analyses at SSU, actin, and HSP70 loci demonstrated that C. myocastoris n. sp. is distinct from other valid Cryptosporidium species.

Resumen: En México existen tres especies de nutrias: dos de río y una marina. La nutria marina o "viejo de mar" Enhydra lutris nereis (Merriam, 1904), ha sido considerada extinta, aunque hay indicios de su presencia en Baja California. En México existen dos subespecies de la nutria de río del norte: Lontra canadensis sonorae (Rhoads, 1898) en el noroeste, y Lontra canadensis lataxina (Cuvier, 1823),en el noreste. La situación de esta especie es desconocida. Por último, la nutria de río neotropical, Lontra longicaudis annectens (Major, 1897), se encuentra distribuida en casi todos los grandes ríos de las planicies costeras, arroyos, lagos, presas y lagunas costeras. Esta especie se adapta a una variedad de habitats, desde las regiones áridas con bosque espinoso y matorral, hasta los bosques tropicales perennifolios y subcaducifolios, y desde el nivel del mar con bosque tropical caducifolio, hasta 1,700m en el bosque mesófilo de montaña. La población de la nutria de río neotropical está declinando en México por una serie de factores generados por el ser humano: desechos industriales y urbanos, envenenamiento de los ríos, el uso de pequeñas cantidades de TNT para la pesca de subsistencia familiar, la apertura de nuevas áreas para la agricultura y el sistema agrícola de roza, tumba y quema de los bosques tropicales. Los arroyos y ríos de las sierras tropicales con cauces perennes que aún poseen la vegetación de galería original y una marcada época de lluvias, son los hábitats más estables.En función de lo cual son las zonas propuestas para la conservación de las nutrias de río.Abstract: There are two species ofriver and one species ofsea olters in Mexico. The sea olter or "viejo de mar" Enhydra lutris nereis (Merriam, 1904), has been considered extinct, ven though there are signs that a few survive in Baja California. In norhtern Mexico there are two subspecies of the river olter Lontra canadensis. L. canadensis sonorae (Rhoads, 1898) is found in northwestern Mexico, and L. canadensis lataxina(Cuvier, 1823) is found in northeastern Mexico. The conservation status of this species is unknown. Finally, the southern river olter Lontra longicaudis annectens (Major, 1897) is distributed along most rivers ofthe tropicallowlands, small rivers, lakes, damns and estuaries. This species adapts to a variety of habitats, from the arid regions with spiny bushes and scrub, to the tropical rain forests, from the sea level in the tropical dry forests up to 1,700m in cIoud forcsts.In Mexico, the population of the southern river otters is declining due to human activities: industrial and urban waste, river poisoning, the use of small amounts of TNT for fishing for familiar subsistence, the opening of new areas for agriculture and the cutting and burning oftropical forests. AlIthe localities with the original vegetation, perennial rivers and a well marked rainy season, are the more stable habitats. Based on this, these areas are proposed for the river otter's conservation.Palabras clave: distribución, conservación, nutrias, Lontra, Enhydra, México

Abstract The parasitic status in the coypus (nutrias) Myocastor coypus, both farm-bred or free-living on river banks in the Czech Republic, was determined. Faecal samples were collected from 200 coypus originating from 11 farms (farm-bred animals) and from 20 individuals living at 14 natural localities (feral animals). Faeces were examined for nematode eggs and coccidian oocysts using the McMaster method. The evaluation of faeces from farm-bred coypus indicated infection with the following parasites: Trichuris sp., Strongyloides sp., Trichostrongylus sp., Eimeria seidelli, Eimeria nutriae, Eimeria coypi, and Eimeria myopotami. Free-living feral rodents harboured Eimeria nutriae, E. coypi, Strongyloides sp. and in one case also Trichuris sp. An additional visceral examination of 20 coypus originating from five farms revealed two nematode species in the gastrointestinal tracts, namely Trichuris myocastoris and Strongyloides myopotami. The study indicated that feral coypus are far less parasitized than their captive counterparts.

Full textAbstract:
Sex differences in growth, blood indicators, carcass values and meat quality in nutrias were evaluated. In the fattening experiment, 136 nutrias of both sexes (1 : 1 ratio) were fattened until 8 months of age. At the end of the experiment, 18 males and 18 females with average weights were selected for the determination of biochemical indicators, carcass value and meat quality. The growth of males was significantly higher than in females; the differences were 12% at three months of age and increased to 24% at eight months of age. The effect of sex on the biochemical indicators of blood was observed in total protein (P ≤ 0.029), albumin (P ≤ 0.012), urea (P ≤ 0.019) and cholesterol (P ≤ 0.026), with higher values in males. In the case of haematology examination, the significantly higher values in males were in the number of erythrocytes (5.10 × 10<sup>12</sup>/l) and in the haematocrit value (55.8%). Dressing out percentage was higher in males (P ≤ 0.039), and other parameters of carcass value were not affected by sex. For the meat physical properties, only lightness (P ≤ 0.019) was higher in males. In the case of the chemical composition of meat, ether extract (P ≤ 0.033) and energetic value (P ≤ 0.024) were lower in females. The results of this study show high differences in the growth of male and female nutrias, whereas carcass composition, physical meat quality and meat chemical composition are less affected by nutria sex.

AbstractThe North American river otter (Lontra canadensis) is considered extinct in Mexico because there have been no records since the last century. In contrast, the Neotropical river otter is widely distributed in tropical and subtropical regions of the country. There are recent otter records identified as L. longicaudis in the San Pedro River, tributary of Rio Conchos, in the Chihuahuan Desert. With field work and morphological, ecological and biogeographical evidence we evaluated the identity of these specimens and concluded that they are in fact a relict population of L. canadensis. This is the first time that the species is recorded in Mexico in a century. This is a very relevant finding for the biological diversity of Mexico.

The article is devoted to the finding a way to determine optimal time for insemination of nutria. This gives an opportunity to improve reproduction what will improve profitability of nutrition as an animal industry.Known for today’s ways to determine optimal time for insemination of nutria have shortcomings, what limits their use. To this end we tested vaginal cystoscopy (colposcopy). This method is not so expensive, it is simple and easy to use. It allows you to define a clear relationship between cytological picture of vaginal smears and hormonal status in a specific period of the sexual cycle.We installed, that in the picture of vaginal smears from the beginning to the middle of proestrus, we can see erythrocytes and parabasal cells, which have a large nucleus, which occupies almost half of the cytoplasm. With a growing level of estrogens instead of basal cells appear intermediate cells reduces the numbers of erythrocytes.During the transition period of the proestrus stage to the estrus stage vaginal swab is characterized by reducing the number of intermediate cells and increase in the number of surface cells. Also we can see non-nuclear cells. Clearly it is visible contours of cells. The appearance of surface cells coincides with the stage of ovulation of the sexual cycle.The same picture of vaginal swab with lots of surface cells we can see in second, sometimes on third day after childbirth. So, the first two days after childbirth is conductive to fertilization period in nutria.In the end of estrus the vaginal swab has changes again: appear epithelial cells with a small nucleus, also we can see many leucocytes.So, the one of the main characteristics of vaginal swab in the period of ovulation in nutria is appearance of non-nuclear surface cells with clear contours and semitransparent cytoplasm. In the development perspective the use of colposcopy to assess the condition of the fetus and the course of pregnancy for further develop methods of diagnosis and prevention of pathologies in ante-, intra- and postnatal periods of development of nutrias puppies.

Full textAbstract:
In response to nutria-linked degradation of much of its coastal wetlands, Louisiana established the Coastwide Nutria Control Program (CNCP) in January 2002. CNCP instituted, among other things, an "economic incentive payment” of $4.00 per delivered nutria tail from registered participants in the program. To examine whether this bounty has had an impact on nutria harvest and whether alternative bounty levels can, in general, generate additional harvesting activities, we developed a bioeconomic supply model that relates Louisiana's annual nutria harvests to a suite of economic and environmental factors. Results suggested that the annual nutria harvest is responsive to both the price received per animal and costs. Results also suggested that the nutria harvest has increased as a result of the bounty, but that the initial bounty of $4.00 per tail may be insufficient to achieve the state's goal of harvesting 400,000 animals per year but that a bounty equal to $5.00 per tail would likely achieve the stated goal.

In 2014, the South Korean government initiated the “Nutria Eradication Project” to actively manage and control populations of nutria, an invasive alien species that threatens national biodiversity. In the present study, we examined domestic nutria habitats in 2014 to 2018 and analyzed spatial shifts in habitat distribution to develop management policies and eradication strategies for the South Korean Ministry of Environment. A total of 27,487 nutria individuals were captured over five years upon the initiation of the eradication project. We found that the number of habitat tracks decreased from 1510 in 19 administrative districts in 2014 to 176 in 14 districts in 2018. We examined the distribution of nutria habitat tracks and found a northwestward shift at an average angle of 313.9° and 46,656.9 m. This distribution shift prompted improvements in control policies focused on nutria capture to suppress rodent movement and shifting distributions. We redefined the spatial scope of our control regions accordingly and established isolated environments in each region to prevent further spread. Additionally, resource management was focused in areas showing habitat expansion. Overall, we observed an estimated 54% decrease in nutria habitat tracks from 2016 to 2017. Our results have since been enacted in government policies and provide a basis for establishing flexible strategies for effectively controlling nutria habitats and populations. In 2017, the South Korean government allocated additional funds for research and for the development of further control strategies working toward the project’s goals.

The implementation of the state agrarian policy provides for the creation of modern production technologies based on fundamentally new theoretical and practical research and scientifi c and technical solutions that will ensure the dynamic development of various livestock industries. Low cost of maintenance, high reproduction, resistance to diseases of various etiologies – these are exactly the criteria that nutraceuticals meet. Nutria are herbivorous, multiple polycyclic animals that multiply combine periods of lactation and pregnancy. Thus, with minimal costs for feed, the farm has the opportunity to make high profi ts. Breeding nutria is cost-eff ective and requires a more detailed study, the development of this industry in all regions of Ukraine. When breeding nutria in closed conditions, the reproductive ability of young females decreases by 20–30%. Research in the direction of the reproductive function of female nutria is practically not conducted, therefore, the study of this issue is relevant. In this article, we analyzed the methods for diagnosing the optimal insemination time for nutria, taking into account their shortcomings and ease of use, and found that the earlier methods used (before 2000) have many shortcomings, as a result of which farms receive less profi t due to death, as well as spoiled quality of fur and skins during fi ghts between animals. The use of a male probe provides not only a benefi cial eff ect on the development of the reproductive system of female nutria, but also allows timely determination of the optimal time for insemination of female nutria. The disadvantage of this method is the cost of drugs for epididiotomy and the postoperative period. Colpocytoscopy is an inexpensive, convenient, non-traumatic, and highly accurate method for determining the optimal insemination period in female nutria.

Several eradication programs have been developed and executed to curb alien invasive species that tend to damage the ecological environments they colonize; however, only few studies have evaluated the utilization of carcasses of these species after eradication. Nutria (Myocastor coypus) is an invasive rodent species targeted by eradication programs in many countries. We noted that nutria produce large amounts of ursodeoxycholic acid (UDCA) in their bile. UDCA is a unique component responsible for the anti-inflammatory and hepatoprotective effects exerted by bear bile. Therefore, we sought to examine the medicinal utility of nutria carcasses by investigating the hepatoprotective effect of their bile in mice. C57BL/6 mice were injected with thioacetamide (TAA), which induced liver damage by increasing Kupffer cell infiltration. Administration of nutria bile reduced hepatic inflammation, improved hepatic function, and increased the levels of senescence marker protein 30 (an indicator of hepatocyte viability). Our results show that nutria bile exerts protective effects against TAA-induced liver injury in mice, suggesting that nutria carcasses may be used for the treatment of liver injuries.

Nutrias (Myocastor coypus) were imported to South Korea for farming in 1985; individuals escaped captivity and established wild populations in natural ecosystems in the late 1990s. Numerous studies have focused on their monitoring and management; however, information on the continuous movement of individuals is not available. In this study, telemetry data from field conditions were used to identify the nearest-neighbor distances of individuals in association with environmental factors, including plant type, land cover, and biological parameters. The minimum nearest-neighbor distances for the different sexes were, overall, according to the minimum distances for the same sex. Local co-occurrences of individuals, either of the same or different sex, were seasonal. Tall grasslands, followed by herbaceous vegetation, were associated with the co-occurrence of different sexes. Conversely, floating-leaved hydrophytes, followed by xeric herbaceous vegetation, were correlated with the co-occurrence of the same sex. Local female–male co-occurrences were negatively associated with male–male co-occurrences but not with female–female co-occurrences, suggesting male dominance in group formations. Movement and co-occurrence information extracted using Geo-self-organizing maps furthers our understanding of population dispersal and helps formulate management strategies for nutria populations.

Se muestreó el río Peñas Blancas y tres de sus tributarios en busca de indicios de la nutria y la medición de siete variables ambientales con el fin determinar la probabilidad de ocurrencia y detectabilidad. Además, se determinó el uso de presas por parte de la nutria neotropical. Las variables ambientales mostraron que el ancho del río y la proporción de bosque fueron las variables más influyentes en la ocurrencia de la especie. El caudal de compensación del río Peñas Blancas mostró la probabilidad de ocurrencia más alta. En cuanto a la dieta de la nutria, los peces fueron la categoría de presa más frecuente en los últimos años. Los datos obtenidos indican la influencia de condiciones físicas del río sobre la ocurrencia de la nutria y la importancia de los peces como componente alimenticio.

Abstract The occurrence of ectoparasites in wild nutria is poorly understood. Fifty-five livetrapped wild nutria (Myocastor coypus) from its indigenous region were examined for ectoparasites after capture from December 2013 to December 2014. The captures came from the Buenos Aires Province, by far the area of the country most densely populated by nutria, characterized as a temperate grassland, which are prime areas for sustained agriculture. Only one species of chewing lice (Pitrufquenia coypus, Marelli, 1932), one flea (Nosopsyllus fasciatus, Bosc, 1800) and one tick (Rhipicephalus sanguineus, Latreille, 1806) were collected. Fourteen percent of the animals were infested and P.coypus, an obligate parasite of the nutria, which was the most prevalent ectoparasite. N. fasciatus and R. sanguineus occurrence remains controversial as they may or may not be some accidental host species. To our knowledge, this is the first comprehensive and systematic survey of ectoparasites in wild nutria from the southern hemisphere, the indigenous region of this species.

The ratio of polyunsaturated fatty acids (PUFA) to saturated fatty acids (SFA) was lower in nutria than in rabbit meat (0.55-0.58 and 0.93-0.94, respectively). The n-6/n-3 PUFA ratio was 15.3 (MS) and 11.22 (m. longissimus dorsi, MLD; loin) in nutria meat and 7.55 and 8.08 respectively in rabbit meat, which appeared more beneficial for the consumer. Among the most important texture parameters, hardness ranged from 66 for MS to 73 N for MLD, and overall chewiness was 23 N. The collagen content was between 0.68 and 0.72%. The results show that in comparison with rabbit meat, nutria meat has valuable properties and is recommended for the human diet.

OBJETIVO: Investigou-se os efeitos do tratamento com triptofano sobre o consumo alimentar em ratos adultos, submetidos ou não a desnutrição precoce. MÉTODOS: Sessenta e quatro ratos Wistar machos foram divididos em nutridos (n=32, caseína=17%) e desnutridos (n=32, caseína=8%), de acordo com a dieta materna empregada no período de lactação. Após o desmame, todos os ratos receberam dieta com 23% de proteína. Pesos corporais foram avaliados no sétimo, vigésimo primeiro e septuagésimo dias de vida. Aos setenta dias de idade, cada grupo nutricional foi dividido em subgrupos: Nutrido-Salina (n=16) e Nutrido-Triptofano (n=16), Desnutrido-Salina (n=16) e Desnutrido-Triptofano (n=16). Os grupos receberam diariamente 1,0mL/100g de triptofano, na dose de 50mg/kgP ou salina (0,9%NaCl), durante 14 dias. Neste período foram realizados os estudos dos parâmetros do comportamento alimentar. Posteriormente obteve-se a média do consumo alimentar relativo e a média do ganho de peso relativo. As análises estatísticas foram feitas utilizando os testes t Student e ANOVA seguido de Tukey, com p<0,05. RESULTADOS: As ninhadas de mães alimentadas com dieta hipoproteica mantiveram pesos inferiores comparados com as ninhadas nutridas (p<0,01) até os setenta dias de vida. Os ratos nutridos tratados com triptofano (M=6,88, DP=0,05) reduziram a ingestão alimentar comparados aos nutridos salina (M=7,27, DP=0,08) (p<0,01). Contudo, não houve efeito sobre o ganho de peso. Entre os desnutridos nenhuma diferença foi encontrada. CONCLUSÃO: Nesse estudo, a restrição proteica neonatal alterou a evolução ponderal em ratos. Além disso, a desnutrição precoce tornou os ratos adultos resistentes aos efeitos inibitórios do triptofano sobre a ingestão alimentar.

Full textAbstract:
Background: The nutria (Myocastor coypus) is a medium-size, semi-aquatic rodent, valued in skin and meat industry. The brain circulation has been well studied in rodents but not in nutria. To understand and compare the phylogenetic development of the arteries of the base of the brain in rodents, this paper aims to describe and systematize these arteries, establishing a standard model and its main variations in nutria.Materials, Methods & Results: Following approval by the Ethics Committee of Federal University of Rio Grande do Sul, thirty nutrias from a commercial establishment authorized by Brazilian Institute of Environment and Natural Resources (IBAMA) were studied. For euthanasia, was applied heparin (10000 U.I for animal), intraperitoneally, and after thirty minutes the animals ware sedated with acepromazine (0.5 mg/kg) and meperidine (20 mg/kg), intramuscularly. After sedation, they were euthanized with thiopental sodium (120 mg/kg) and lidocaine (10 mg/mL), intraperitoneally. The heart was accessed, the cardiac apex was sectioned, the aorta was cannulated via the left ventricle and clamped close to the diaphragm, and the arterial system was washed with saline solution and filled with latex. The animals were submerged in water for latex polymerization, the trunk was sectioned, the skin removed and a bony window was opened in the skull vault. The pieces were fixed in formaldehyde. The brains were removed, and schematic drawings of the arteries from the base of the brain were made for elaboration of the results. The nutria’s brain was vascularized by the vertebro-basilar system. The terminal branches of the right and left vertebral artery were anastomosed on the ventral surface of the medulla oblongata, forming the basilar artery, and caudally the ventral spinal artery. The basilar artery formed collateral branches, the caudal and middle cerebellar and trigeminal arteries, and at the height of the rostral pons groove, divided into its two terminal branches, the rostral cerebellar and cerebral caudal arteries. The terminal branches of the basilar artery projected rostrally, forming the hypophyseal and rostral choroid arteries. The basilar artery passed the optic tract and bifurcated in the middle cerebral artery, its last collateral branch, and in the rostral cerebral artery, its terminal branch. The rostral cerebral artery formed the medial branch, closing the cerebral arterial circle caudally in 40% of the cases.Discussion: In rodents, variability of the cerebral arterial circle was observed due to the degree of atrophy of the internal carotid artery. The basilar artery was a rectilinear vessel of great caliber in all described rodents, and in rodents with a vertebro-basilar system, it was divided into its terminal branches after crossing the pons, forming the rostral cerebellar, hypophyseal, rostral choroid, caudal, middle and rostral cerebral arteries. The caudal cerebellar artery had variation of origin and sometimes duplication. The median cerebellar artery, a collateral branch of the caudal cerebellar artery, was a branch of the basilar artery in capybara. The caudal cerebral artery had variations between rodents. In capybara, chinchilla and nutria the middle cerebral artery was the collateral branch of the terminal branches of the basilar artery, and distributed on the convex surface of the cerebral hemisphere. The rostral cerebral artery, a branch of the terminal branch of the basilar artery, was a branch of the internal carotid artery in other rodents, forming the medial branch, which was anastomosed with that of the opposite antimer, when present, forming the rostral communicating artery. In nutria, the cerebral arterial circle was closed caudally in all cases, as in other rodents, however, it was opened rostrally in 60% of cases, compared to 70% in chinchilla and 10% in capybara.

The formation of hydrophobized nutria fur velour has been carried out using the optimized alkenmalein acrylsyntane composition. Based on the implementation of the synthesized experimental plan “composition-properties of velour” by the modified McLean-Anderson method, the optimization of filling and hydrophobizing composition has been performed by Harrington method. The optimized composition involves the use of, wt. %: alkenmalein polymer – 54.1, polyacrylic emulsion Melio Resin A-821 – 18.8, reagent based on 2-naphtholesulfonic acid and dioxins-phenylsulfone – 27.1. The developed technology of forming hydrophobized nutria velour has been tested at the experimental production of leather enterprise (Chinbar Private Joint Stock Company, Kyiv, Ukraine). Nutria fur velour obtained by the developed technology is characterized by a significant increase in water resistance in dynamic conditions. The advantage of this technology is the production of fur velour with a higher yield of 5.4–5.6 % compared to the semi-finished chromium-aluminum tanning. The optimized filling and hydrophobizing composition can be effectively used in the technologies of manufacturing sheepskin and leather materials with high water resistance. According to the complex of properties, the obtained hydrophobized nutria velour is suitable for the production of uncovered items of various purposes, which will be used in extreme conditions.

AbstractWe examined the endoparasites of wild nutria from the native region of South America. Individuals were infected with nineteen species, including Nematoda (82.0 %), Protozoa (46.1 %), Trematoda (33.3 %) and Cestoda (12.8%). Coccidia (Eimeria sp. or Isospora sp.), Strongyloides myopotami and Trichuris myocastoris were the most abundant and prevalent parasites. The diversity of parasite collected on individual hosts ranged from one to four species. There was no significant association between either the age or the sex of the nutria and the prevalence of parasitism, except that the number of infested nutria less than 1 year by Nematoda was significantly higher than in older individuals. Additionally, Cryptosporidium spp. and Giardia spp. were demonstrated in fecal samples, although scarcely. In general, the accessions were found in good bodily condition and carrying low parasite burdens. These numbers appeared insufficient to indicate gastrointestinal parasitism or parasitic disease.

Full textAbstract:
Nutria (Myocastor coypus) is a large rodent native to South America which was introduced worldwide originally with the intention of fur farming. Three colour forms (Standard, Moravian Silver, and Prestice Multicolour) fall into the Farm Animal Genetic Resources of the Czech Republic protected by the National Programme on Conservation and Utilization of Plant, Animal and Microbial Genetic Resources for Food and Agriculture coordinated by the National Focal Point. The objective of our investigation in the Czech Republic was to establish microsatellite panel for nutria and determine microsatellite variability in the local nutria population, levels of genetic diversity within and among subpopulations with respect to colour form and the levels of inbreeding within subpopulations. The genetic variability was studied in 64 animals by investigating 11 microsatellite markers (McoD214, McoD217, McoD59, McoD69, McoC124, McoC203, McoD60, McoB17, McoC118, McoA04, and McoD228) analysed by multicoloured capillary electrophoresis. The whole population showed a moderate level of genetic variability in terms of number of alleles (5 alleles per locus) or heterozygosity (50.4%) and the Prestice Multicolour form exhibited the highest level of diversity. Particular attention should be paid to organizing mate to minimise inbreeding, especially in the Standard colour form (F<sub>IS</sub> = 0.238) which showed the highest level of inbreeding out of the three colour forms. High combined exclusion probability (CEP) values (99.5, 94.5, and 99.9%) implied that the panel of microsatellite markers established in this study was usable for individual identification or routine parentage testing in nutria population in the Czech Republic.

Nutrien merupakan faktor penting dalam pertumbuhan mikroalga. Amonia merupakan salah satu sumber nutrien yang paling disukai oleh mikroalga karena langsung dapat dimanfaatkan di dalam tubuh mikrolaga. Meskipun amonia paling disukai, namun keberadaannya dalam jumlah besar dapat berdampak buruk pada mikroalga. Sifat racun pada amonia dapat menyebabkan kematian pada mikroalga. Penelitian ini bertujuan untuk mencari komposisi penambahan nutrien yang paling sesuai pada proses kultivasi mikroalga. Variasi penambahan NPK cair (nutrien) yang dipilih pada penelitian ini yaitu 0 mL; 0,3 mL; 1 mL; dan 2 mL. Penelitian dilakukan dengan sistem batch teraerasi. Variasi yang dianggap paling sesuai untuk proses kultivasi mikroalga yaitu variasi penamabah NPK 0,3 mL.

Both Cacl2 and Nutrical (a trihydroxyglutarate chelate) were foliarly applied at rates of 1.8 and 5.5 Cacl2/ha/season and 1.5 and 4.5 l/ha/season, respectively. Applications were made starting at shuck split and repeated at 2 week intervals until harvest. Neither calcium treatment had an effect on fruit size and size distribution. Fruit size was directly related to crop load. Calcium chloride application had the most pronounced effect on increasing the red over-color of `Cresthaven' peaches with Nutrical intermediate compared to the control. The high rate of Nutrical increased flesh calcium levels at harvest by 75-100 PPM. Instron Texture Profile Analysis indicated that any calcium treatment significantly increased the hardness of the peach. Nutrical at 4.5 l/ha/season improved hardness 2-fold compared to the controls. The improved hardness was maintained throughout the 6 week storage period.

In 1995 nam het toenmalige kindervoedingconcern Nutricia het niet veel kleinere, eveneens op Europese schaal werkende, in Duitsland gevestigde Milupa over. Deze acquisitie verzekerde voor lange tijd het voortbestaan van wat nu Numico heet. De financiële modellering van de overname rustte op vier peilers: 1) een uitgewogen strategische visie, 2) een gedetailleerde kennis van productieprocessen, 3) het goed doorgronden van Milupa’s boeken en 4) het weg willen werken van subjectiviteit. De financiële investeringsselectie gebeurde primair conform de financieel-economische theorie: de IRRmethode stond voorop. Daarnaast werd ook de communicatiefunctie van boekhoudkundige methoden naar financiële markten op waarde geschat. De communicatie tussen ‘de wetenschap’ en ‘de praktijk’ kan echter nog wel wat beter.

Gangguan pertumbuhan pada thalassemia disebabkan oleh banyak faktor antara lainfaktor nutrisi. Gangguan pertumbuhan akibat kekurangan gizi dapat menyebabkanperawakan pendek. Nutrisi yang adekuat sangat penting untuk pasien thalassemia sebagaimodalitas dalam pengobatan jangka panjang dan untuk mencegah gangguan gizi,gangguan pertumbuhan, perkembangan pubertas dan defisiensi imun. Asupan nutrisiyang dianjurkan pada thalassemia adalah tinggi kalori, protein, kalium, seng, vitaminA,D, E, rendah besi sedangkan vitamin C harus dikurangi karena dapat meningkatkanabsorpsi besi. Suplementasi vitamin C dosis rendah diberikan bersamaan denganpenggunaan desferoksamin untuk membantu meningkatkan pengeluaran besi.

Full textAbstract:
La nutria marina, gato marino o chungungo (Lontra felina) es considerada virtualmente una especie exclusiva marina con una preferencia de hábitat rocosos de litoral en la costa pacífica de Perú y hasta Tierra del Fuego al sur de Chile y la Isla de los Estados en el sur de Argentina. En esta nota científica se presentan registros fluviales de la nutria marina. En el río Cotahuasi (cuenca del río Ocoña) se tiene un registro hasta la localidad de Sipia, a 171 Km del litoral y a 1 994 m de altitud. En la cuenca del río Colca (cuenca Majes), el registro más alejado es en la laguna Mamacocha en la provincia de Caylloma, a 157 Km del mar a una altitud de 1 702 m.Se presentan además otros registros directos e indirectos hasta la desembocadura de estas cuencas. El registro de esta especie en dos de los ríos más grandes del suroeste de Perú y no en los demás (departamentos de Moquegua y Tacna), posiblemente se deba a la configuración extremadamente encañonada, lo que puede representar un refugio para esta especie amenazada, además de tener una abundante oferta alimenticia. Se considera necesario incluir acciones de conservación en la distribución fluvial de la nutria de mar, debido a que actividades como la construcción de presas, afectarían significativamente su presencia en este espacio y hábitat de su distribución, en gran medida desconocido.

Penelitian ini bertujuan untuk mengevaluasi kandungan nutrien dan antinutrien tepung daun kelor terfermentasi sebagai sumber protein nabati pakan ikan. Tahap penelitian meliputi pembuatan tepung daun kelor, persiapan dan penghitungan kepadatan bakteri, proses fermentasi, dan analisis kandungan nutrien dan antinutriennya. Bakteri yang digunakan untuk fermentasi merupakan campuran bakteri T2A (Bacillus sp.), T3P1 (Bacillus sp.) dan JAL11 (Lactococcus raffinolactis) dengan kepadatan sebesar 2,16x109 cfu/mL. Fermentasi tepung daun kelor dilakukan selama 168 jam. Analisis kandungan nutrien dan zat antinutrien tepung daun kelor terfermentasi dilakukan pada jam ke-24, ke-48, ke-72, ke-96, ke-120, ke-144 dan ke-168. Kandungan nutrien tepung daun kelor meliputi kadar air (9,04±0,00%), abu (9,70±0,21%), protein (25,77±0,08%), lemak (4,80±0,52%), serat kasar (11,60±0,13%), bahan ekstrak tanpa nitrogen (39,06±0,52%), energi (351,27±3,27 kkal/00 g), hemiselulosa (13,79±0,07%), selulosa (9,9±0,06%) dan lignin (15,34±0,31%). Fermentasi dapat meningkatkan kadar air, abu, protein dan lemak, serta menurunkan kadar serat kasar, bahan ekstrak tanpa nitrogen, hemiselulosa, selulosa, lignin dan antinutrien, antara lain fenol, tanin, asam fitat dan HCN. Hasil penelitian menunjukkan bahwa fermentasi dapat meningkatkan kandungan nutrien dan menurunkan kandungan antinutrien tepung daun kelor, sehingga dapat digunakan sebagai sumber protein nabati pada bahan baku pakan ikan.

Kegiatan yang terdapat di sekitar muara Sungai Sayung seperti aktivitas manusia, pariwisata, industri rumah tangga, pertambakan, serta jalur pelayaran yang terus berlangsung tanpa pengelolaan yang baik dapat menyebabkan perubahan kondisi fisika, kimia, biologi sehingga akan berpengaruh terhadap kandungan bahan organik, nutrien, dan kelangsungan hidup organisme di dalamnya. Tujuan penelitian ini adalah mengetahui fluktuasi dan sebaran bahan organik di muara Sungai Sayung Demak, mengetahui distribusi spasial sebaran bahan organik dan nutiren terhadap kelimpahan fitoplankton, dan mengetahui keterkaitan antara bahan organik terhadap sebaran nutrien dan distribusi nutrien terhadap klorofil-a.Penelitian ini berdasarkan studi kasus dan menggunakan metode purposive sampling untuk pengambilan sampel. Dalam penelitian ini ditentukan lima stasiun pengukuran, dimana pada tiap stasiun dilakukan tiga kali pengulangan. Analisis data bahan organik, nutrien, dan klorofil-a menggunakan metode Regresi Korelasi. Bahan organik dengan nitrat secara linier menunjukkan keeratan yang tinggi dengan nilai koefisien korelasi (R) sebesar 0,8209. Hubungan antara bahan organik dengan fosfat mempunyai nilai koefisien korelasi (R) sebesar 0,7804. Distribusi nutrien terhadap klorofil-a menunjukkan adanya gradasi nilai konsentrasi dimana di muara Sungai Sayung lebih tinggi dan akan semakin rendah menuju ke arah laut lepas. Berdasarkan nilai rata – rata klorofil-a yang diperoleh sebesar 1,027 – 1,353 µg/l, perairan muara Sungai Sayung Demak tergolong kedalam perairan yang bersifat Oligotrofik.

Adequately organized nutritional support allows avoiding the development of protein-energy malnutrition in patients with bronchopulmonary diseases and cystic fibrosis (CF). The satisfying of increased protein and energy needs of CF patients can only be implemented under the administration. The aim of the study is to analyze the tolerance and effectiveness of the use of domestic sterilized liquid specialized high-protein high-calorie mixtures «Nutrien Pulmo» and «Nutrien Energiya with Dietary Fibers» in children over three years of age with acute (pneumonia) and chronic (cystic fibrosis) forms of bronchopulmonary pathology. Patients and methods. Fifty-five children, including 41 patient suffered from CF, 14 cases with pneumonia, aged from 3 to 18years, were under observation. Of these, 23 (42%) children received Nutrien Pulmo, 32 (58%) children received Nutrien Energiya with Dietary Fibers. Nutritional status was assessed using the WHO-Anthro programs (for children from 3 to 5 years old) and WHO-Anthro Plus (for patients over five years) and clinical and biochemical blood test indices. The observation period was accounted for three weeks. Results. All patients highly appreciated the taste of the products, there were no refusals to take specialized mixtures, neither adverse events during the observation period. While taking specialized mixtures, there was a positive trend in anthropometric indices and a significant improvement in biochemical markers of nutritional status: an increase in prealbumin, total protein, transferrin level. Conclusion. The use of specialized domestic products «Nutrien Pulmo» and «Nutrien Energiya with Dietary Fibers» in the diet therapy of children with acute and chronic bronchopulmonary pathology has the safe and positive effect on the nutritional status of patients.

Full textAbstract:
The growth and development of children is influenced by multiple factors like genetics, general health, physical activity, sedentary, sleep quality and proper nutrition. The disturbance of these factors during the pre-school period can negatively influence the health of the older child and later of the adult. An essential part of pediatrics is prevention. Pre-school care should provide opportunities for promoting healthy behaviours for appropriate physical and psychosocial development.
