COMPARATIVE CHARACTERISTICS OF DI-AGNOSTIC LABORATORY TESTS FOR THE VIRUS PERITONITIS OF CATS

abstract 1471903031 issue 147 pp. 0 – 0 29.03.2019 ru 27
This article is devoted to the study of various laboratory tests for the diagnosis of viral peritonitis of cats, conducted in 2014-2018. The study was subjected to 278 cats of both sexes, different breeds and mongrel, of different ages, which were taken to the veterinary clinic «Vita» and the veterinary clinic «Noah's Ark» in Krasnodar. Analysis of the results showed that in the diagnosis and differential diagnosis of viral peritonitis of cats, the most resultant is a combination of studies of Globulin in serum and a test for antibodies to coronavirus, or a solid enzyme immunoassay (tIFA) on IgG to coronavirus. In addition to clinical symptoms, routine laboratory studies, instrumental studies for the diagnosis of viral cat peritonitis, it is necessary to use additional research methods, although many of them have a number of shortcomings in sensitivity and specificity

DEVELOPMENT AND JUSTIFICATION OF ZOOHYGIENIC ACTIVITIES TO IMPROVE THE PRODUCTIVITY OF BIRDS AND THEIR EPIZOOTIOLOGICAL SUSTAINABILITY IN CLOSED POULTRY HOUSES

abstract 1491905035 issue 149 pp. 0 – 0 31.05.2019 ru 31
The problems of creating an optimal microclimate in the closed workshops of poultry farms are relevant for the regions of the south of Russia and the Northern Caucasus, especially acute these problems are for Kabardino-Balkaria. The used zoohygienic measures and existing ventilation systems of closed poultry houses need to be improved and adapted to the local natural conditions. The purpose of the work was to research and develop effective ventilation systems for closed poultry houses in hot climates. Existing ventilation systems and zoohygienic conditions in closed-type poultry houses were studied and investigated. According to the results, the main disadvantages of the existing ventilation systems and their low efficiency were established. And on their basis, new technical solutions have been found to create more efficient ventilation systems for closed poultry houses that provide the optimal microclimate: temperature, humidity and pressure. With the active participation of the author, new technical solutions have been developed and proposed, for which two applications for obtaining patents have been prepared: one for a utility model - for a device for moistening and cooling wall ventilation ducts of poultry houses; the second is for the invention - on the method of erecting a cooling system and humidifying the ventilation panels of the supply. During their implementation, these new technical solutions allow creating such a microclimate, thanks to which optimal indicators of productivity and growth, uniformity, efficiency of feed and meat gain are achieved, without reducing the characteristics of the health and well-being of birds. Ventilation is becoming a major factor in microclimate control in closed houses and the epizootological resistance of birds

PLUMAGE COLOR GENE INTERACTION IN CHICKENS (REVIEW)

abstract 1411807021 issue 141 pp. 97 – 110 28.09.2018 ru 41
Coloring the plumage of chickens is a complex genetically determined sign. The study of the interactions of the main genes of chicken pigmentation was started by A.S. Serebrovsky. The most complete information on the genes of coloring plumage of chickens and down of chickens is given by Z.M. Kogan, indicating the clutch groups and the arrangement of these genes on the chromosome map. In the 1990s, the interaction of color genes, pen pattern and modifier genes affecting the intensity of the main color and pattern of the pen was described in detail. It was found that in pigs the pigmentation is regulated by the MC1-R melanocortin receptor associated with the locus E. Due to molecular studies, loci of dominant white color (I), recessive white color (c / c), striped pen pattern (B) adherent to the floor , and spotted spot locus (mo). The final phenotype depends not only on individual genes, but also on their interactions and the genetic environment as a whole. The same genes can produce different patterns and shades of the main plumage, and different genes determine the same phenotypes. Despite the fact that there was significant progress in determining the molecular causes of the appearance of a particular type of color in chickens, much remains to be learned

ALLELE-SPECIFIC PCR FOR TYPING OMPH-TYPES OF PASTEURELLA MULTOCIDA AND SEARCING FOR NEW APPROACHES TO STUDYING OF PATHOGENICITY OF BACTERIAL ISOLATES

abstract 1471903033 issue 147 pp. 0 – 0 29.03.2019 ru 43
Pasteurella multocida is an important respiratory pathogen of cattle. OmpH Protein is a major protective antigen of bacteria has been well studied in avian strains. In the literature there are no data available for the study of a variety of sequence of this protein among isolates with cattle respiratory pathology. There have been described several genes associated with the virulence of the bacterium in respiratory disease of cattle, but none of the authors compared the frequency of detection of these genes with the pathogenicity for laboratory animals. The aim of our study was the development of allele-specific PCR to determine Omph-types of Pasteurella multocida and the search for new approaches to assess the pathogenicity of isolates of bacteria. Total amount of 83 isolates allocated from the lungs of calves with respiratory pathology was investigated. All isolates belonged to groups A or D (isolates 63 and 20, respectively). Among isolates of capsular serogroup A we revealed 6 types, most propagation types were A1 and A2. All isolates of capsular serogroup D were one omph- type. In 16 out of 23 farms there were identified isolates of only one omph-type, 4 - 2 types, 3 - three types. The frequency of gene hgbb - hemoglobin binding protein correlated with pathogenicity of isolates for white mice. The developed allele-specific PCR along with hgbb gene detection can be used for screening and studying the properties of antigen and circulating pathogenic isolates and selecting a candidate vaccine strains

abstract 1361802034 issue 136 pp. 246 – 256 28.02.2018 ru 45
The article gives mechanisms of the influence of the main sex hormones on the sexual cycle of cows and heifers and the effectiveness of their insemination. The effectiveness of gonadotropin preparations releasing hormone, prostaglandin and progesterone, used to induce sexual hunting, was studied. The use of combined use of hormones and prostaglandins is effective for synchronizing sexual hunting, regardless of the stage of the sexual cycle on which healthy animals can be at the time of their administration. The reasons for the retention of the yellow body in the ovary are very diverse. The results of the studies indicate that a particularly close relationship exists between the yellow body and the uterus

FORMATION OF A SEMANTIC KERNEL IN VETERINARY MEDICINE WITH THE AUTOMATED SYSTEM-COGNITIVE ANALYSIS OF PASSPORTS OF SCIENTIFIC SPECIALTIES OF THE HIGHER ATTESTATION COMMISSION OF THE RUSSIAN FEDERATION AND THE AUTOMATIC CLASSIFICATION OF TEXTS ACCORDING TO THE AREAS OF SCIENCE

abstract 1441810033 issue 144 pp. 44 – 102 28.12.2018 ru 45
This work is a continuation of the author's series of works on cognitive veterinary medicine. The present period is characterized by the appearance of huge volumes of texts in different languages in the open access, generated by people. Currently, these texts are accumulated in various electronic libraries and bibliographic databases (WoS, Scopus, RSCI, etc.), as well as on the Internet on various sites. All these texts have specific authors, dates and can belong simultaneously to many non-alternative categories and genres, in particular: educational; scientific; artistic; political; news; chats; forums and many others. The solution of the generalized problem of attribution of texts is of great scientific and practical interest, i.e. studying these texts, which would reveal their probable authors, date of creation, the ownership of these texts to the above generalized categories or genres, and might evaluate the similarities - differences of authors and texts according to their content, highlight key words etc. To solve all these problems it seems necessary to form the generalized linguistic images of texts into groups (classes), i.e. to form semantic kernels of classes. A special case of this problem is the creation of the semantic kernel in various scientific specialties of the HAC of the Russian Federation and the automatic classification of scientific texts in the areas of science. Traditionally, this task is solved by dissertation councils, i.e. experts, on the basis of expert assessments, i.e. in an informal way, on the basis of experience, intuition and professional competence. However, the traditional approach has a number of serious drawbacks that impose significant limitations on the quality and volume of analysis. Currently, there are all grounds to consider these restrictions as unacceptable, because they can be overcome. Thus, there is a problem, the solutions of which are the subject of consideration in this article. Therefore, the efforts of researchers and developers to overcome them are relevant. Therefore, the aim of the work is to develop an automated technology (method and tools), as well as methods of their application for the formation of the semantic core of veterinary medicine by automated system-cognitive analysis of passports of scientific specialties of the HAC of the Russian Federation and automatic classification of texts in the areas of science. A detailed numerical example of solving the problem on real data has been given as well

DYNAMICS OF EGG PRODUCTION IN CHICKENS OF VARIOUS BREEDS OF BIORESOURCE COLLECTIONS

abstract 1371803037 issue 137 pp. 230 – 237 30.03.2018 ru 57
The production of eggs is one of the most important indicators of the productivity of poultry, including chickens The main purpose of breeding chickens in the collections of genetic resources - conservation of genetic diversity. The chickens from the collection of genetic resources it is also possible to receive products, for example, in the form of eggs. The account of the egg productivity of the chickens showed that the intensity of egg production varies among representatives of different directions of productivity. The most stable egg-laying was possessed by chickens of breeds New Hampshire, Black Australian, Dutch white. These breeds are bred as breeds of egg direction of productivity. But they are characterized by long downturns in egg production, lasting more than 7 days. Chickens of meat direction by stable, but low intensity of egg production. All the chickens had a short period For all chickens a short period is characteristic, when the egg-laying is kept at a certain level. It is 30-40 days, after which there is a gradual decrease in this indicator. Such a high level of genetic diversity in egg production in gene pool makes it possible to use this bird as a model object for studying its features
