The greatest contamination of livestock, what time of the year, and optimal weather conditions for the development of eggs and survival of larvas strongilates It is found out. It is determined, at what height above sea level develop invasive larvae of strongilates of gastrointestinal tract, as well as the contamination of routes ferrying with infective larvae of esophagitis nematodir and bunostom.

Aminobenzimidazole derivatives were synthesized, wich have been studied as anti-protist agents. Such compounds can be effectively used to treatment of animals.

Dramatically increased the number of cases of trichinosis in humans associated with the use of meat of wild animals and dogs. In the Voronezh region Trichinella found in nine species of mammals. Infection of wild animals ranging from 12.5 to 36.8%. Among those registered in the Voronezh region hosts Trichinella leading role in the accumulation and dispersal of infective larvae, and thus to maintain functional stability of the natural foci of trichinosis, owns Fox. In the Voronezh region trichinellosis circulates solely as natural focal invasion.

In the genesis of pulmonary hypertension of the dirofilariosis is not only the mechanical factors caused by thrombosis of lungs’ vessels by worms, but also the constellation of metabolic factors. Was researched that infected by Dirofilara immitis dogs have disfunction of histohaematical barrier penetrability for surfactant’s protein-D. Concentration of von Willebrand-factor indicates disfunction of endothelium associated with Dirofilaria immitis infection. Morphological signs of lungs depends on intensity of disease.

In the article was described positire influence ‘of multienzymatic’s drag “Wobezym” on babesiosis of dogs.

The authors carried out the comparative analysis of pathomotphological changes in kidneys of rats experimentally treated with imida – and tiakloprid at the dosage of 1\5 LD50 respectively. There were found that the action of Konfidor Extra is marked by provoking vascular disturbances, dystrophy of epitheliocytes of curved canaliculi, whereas Kalipso by arising parenchymatous mononuclear cells bounds in the organ, fibroblastic proliferation and fibrous connective tissue enlargement.

Hybrid turkeys are characterized by higher content of red cells, leucocytes, haemoglobin, common protein in blood and its serum, hidher activity of АсАТ and АлАТ enzims, that causes increasing of metabolic process, connected with strengthened protein, carbohydrate and energy metabolism in their organism.

On the basis of these experiments improved production technology bifidogenous drug «Lactofit». The effect of the drug on the retention, growth and development of calves and composition of the microflora of the gastrointestinal tract.

The role of teaser rams in the reproduction of sheep in discussed and surgical method of preparation teaser rams cryptorchids is described in the article.

483 samples were obtained in different animals and birds since 2008 to 2011 year. We identified 105 isolates as S. intermedius by biochemical systems (Staphy test 24). For confirmation of the biochemical identification all isolates were identified by Multiplex-PCR for coagulase positive staphylococcoci. As a result 98 strains were identified as S. pseudintermedius (93,3%), 4 (3,8%) – S. schleiferi subsp. coagulans, 2 (1,9%) - S. intermedius and 2 (1,9%) - S. delphini. 1 isolate was not identified.

Cefametrine has marked bactericide and bacteriostatic effect on microorganisms singled out from the cow uterus at the postpartum endometritis

The total number of microorganism in 1 ml of uterine contents of cows which are ill with postnatal endometritis exceeds the above among healthy animals by 1,5 times and is presented by the stamms of Staphylococcus, Streptococcus, Escherichia, Proteus, Enterobacter, Bacillus, Pseudomonas, having different sensitivity to antibiotic.

In the given work the modern biotechnological method of reproduction of the herd, comprehensible to practical use in meat cattle breeding for synchronisation of sexual hunting for the purpose of reception of calfs during the safe periods of giving birth is reflected

It is faund that the cows incidence of acute mastitis by season was distributen more or less evenly – from 15,8 to 25,7%, but in the later winter and carly spring the percentage rose to 37,1%

It is found that a microbe factor plays one of the important reasons at the formation and development of acute mastitis in cows.

E. coli was the most widespread a microorganism allocated from dogs with pyometra (76,6 %). 120 strains E. coli (79,5 %) were positive on a gene sfa, 86 (56,9 %) were positive on a gene cnf, 87 (57,6 %) were positive on a gene pap, 52 (34, 4 %) were positive for hly, 51 (33,8 %) were positive for iuc and 5 (3,3 %) were positive for afa genes. One observed more sensitivity of E. coli to norfloxacin, polimixin B, sulphazotrin, chloranfenicol and enrofloxacin. In 42% of the samples of uterine walls where microorganisms were isolated, the sizes of the areas of the inflammatory responses corresponded to 39-56%. Factors of pathogenicity E. Coli have been identified in 98,0 % studied strains, showing high frequency potentially pathogenic E. coli. Probably, that the dogs, living glad with the man not one thousand years are the important factor in transfer pathogenic E. coli to other animals and the man. Keywords: dogs, Escherichia coli, pyometra, endometritis, diagnostics.

Research results about efficiency of the ferropeptid to improve productivity and for prevention of hypoferric anemia of piglets are presented in the paper

To improve the effectiveness of specific immunization along with the improvement of feeding and keeping of animals, it is advisable to use the biologically active preparations possessing immunomodulating properties. In the experiment on the rabbits revealed that the «STEMB» has immunomodulating effect on the performance of postvaccinal immunity when the vaccine polivalentna «VGNKI» against leptospirosis of animals.

This paper highlights the issues of blood, in the period of post-traumatic period in dogs after multiple injuries. Research has shown that the period of stabilization in the bone marrow and peripheral blood, should be considered the 5th day after injury, changes in the bone marrow and peripheral blood of dogs are stable.

It is found that in the origin and development of inflammatory processes in the uterus hlays a significant role immunobiological system state of organism. From as far as the level of immunity is high, is dependent not only the susceptibility or resistance of cows to endometritis but the level of natural resistance of their offspring.

In this article presents the comparative study of the biochemical indices of the blood serum, characterizing the liver’s functional state in dogs with D. immitis in autumn-winter and spring-summer periods. It was found that the biochemical indicators correlate with the severity of course dirofilariosis, and can be its objective indicator.

In article the comparative analysis of methods of the study of a humeral joint and algorithm of his diagnostics is submitted. Change intraarticular structures is in detail considered at various pathologies.

The authors identified 10 studies of bacteriological cultures (4.5%) Salmonella in foods of animal origin, which may cause consumers gastrointestinal diseases.

The results of epidemiological monitoring of pigeons in Ukraine against paramyxovirus infection, virus isolates identified and studied their biological properties

The article presents data on the development of ELISA kit-systems to detect antibodies to the virus enteritis of geese in one dilution, the results of testing and comparative studies of field sera by ELISA and neutralization test.

The article presents data from the immunohistochemical changes of the lymph nodes and the spleen in wild boars in the experimental reproduction of african swine fever (ASF) with highly virulent field isolate of the ASF second genotype virus, which circulate on the territory of the Russian Federation.

In order to control the state functions in the regional state veterinary surveillance in the Republic of Buryatia developed and approved by the Administrative Regulations, which use state veterinary inspector of the Republic of Buryatia.
