Description
According to the title, the article describes the causes and contributing factors of functional disorders of the uterus and ovaries at cows. The authors specified the percentage incidence of these animals’ pathologies in some farms of Krasnodar Region, especially in industrial complexes. Studies have shown that acute postpartum endometritis has a definite influence on the functional disorders of the ovaries at cows. Authors have found that the cows via 2-4 months after calving with ovarian hypofunction in early postnatal period have had purulent-catarrhal endometritis in 87.9%, fibrinous - in 12% of cases. At cows which have had persistent corpus luteum in 54.6% of cases was registered purulent-catarrhal endometritis, in 27.6% - fibrinous, in 17.8% - necrotizing metritis. At cows with ovarian cysts fibrinous endometritis was observed in 63.2% of cases, necrotizing metritis - in 36.7%. Thus, the more severe form of uterine inflammation was observed in cows, the more severe form of ovarian functional disorders observed in them. The authors found that any factors which negatively acting on the central nervous system or hormone levels, directly or indirectly, sharply reduce the reproductive function of animals

DEVELOPMENT OF A METHOD AND TEST - SYSTEM DETECTION SALMONELLA ON THE BASIS OF LATEX - AGGLUTINATION
DescriptionIn medical practice, RLA as the alarm express train - test for revealing antigenes of microorganisms is convenient at use in diagnostic laboratories, and also at carrying out of mass inspections. To advantages of RLA, as a method of serologic diagnostics of bacterial and virus infections, it is possible to attribute the following moments: high specificity and sensitivity; absence of necessity for the complex equipment for statement and reactions and registration of results; data up to a minimum of quantity of components of reaction; an opportunity of reception of inert carriers with the set characteristics; an opportunity of reception of inert carriers with the set characteristics

DISTRIBUTION AND SPECIES COMPOSITION OF PECTORIS AND RHODOCOCCUS
DescriptionThere are numerous reports about the possibility of sensitization to tuberculin animals when infected with pectoris and Rhodococcus and it is considered to be expedient to create one monoallergenov to differentiate allergic reactions. In this context, the spread of pectoris and Rhodococcus in nature, the general physico-chemical and biological properties of mycobacteria, increasingly emerging reports of a possible sensitization of the microorganism, require a detailed study of them in order to determine the specificity of allergy

THE RESULTS OF IMPLEMENTATION OF CATTLE EMBRYOS TRANSPLANTATION
DescriptionThe results of the analysis of the level of implementation of the method of cattle breeding by embryo transfer in an agricultural company from the Krasnodar region with a developed sector of cattle breeding. We have assessed the level of development of all stages of the method in the household, identified errors in the selection of animals and the increased value of culling donor cows and recipients, reduced duration of using recipient cows and high cost of all phases of the transplant process. We have raised a question of the need to change the criteria of economic evaluation of the results of the method

SEROLOGIC CONTROL OF SPECIFIC PROPHYLAXIS OF THE CANICOLA FEVER OF CATTLE
DescriptionResults of studying of the immune response of young growth of cattle to vaccination against a canicola fever are presented in article. Dependence of duration of circulation of antibodies in a blood of the vaccinated young growth of cattle from degree of intensity of an immune response on introduction of the vaccine is revealed. Studying of dynamics of antiserum capacities at cow calves of two-month age after immunization taped the weak immune response on introduction of a vaccine. It is expressed both in total absence of antibodies, or available antibodies in minute quantity to canicola fever of one of the serogroups which are a part of a vaccine. Use of immunomodulatory preparations for rising of efficiency of immunization of cow calves against a canicola fever is offered. It is established that application of "Ribotan" at vaccination of two-month calves against a canicola fever increases efficiency of immunization for 55,6 %

THE METHOD OF THE MICROBIOLOGICAL ANALYSIS OF THE AIR
DescriptionThe article represents the characteristics of different methods of air microbiological analysis on the basis of the results of patent searches, the aim of which is to identify and develop the most effective methods for microbiological evaluation of air quality in livestock buildings. This problem has particular relevance in the implementation of anti-epizootic measures. Among the studied methods of air microbiological analysis was used the new method which allows accurate counting degree of bacterial contamination, due to the additional coverage of molten and cooled to 45 ° C in culture medium, the density of which is not less than the density of the main medium. The new method for the microbiological analysis of air was developed and offered for practical application, including the sedimentation of aerosol particles and seeding microorganisms containing in the air at the surface of dense main medium, the temperature control of the samples and the count the microorganisms colonies number

Description
The article presents the use of intensive methods of diet herd reproduction that will increase the productivity and profitability of the sheep industry. One of such methods is in vitro fertilization (IVF). For the success of in vitro fertilization procedure, an important requirement is the availability of highquality nutrient media, which help to preserve the genetic material and contribute to the further development of the zygote. The main requirement to the media for sperm is the ability of media not to cause their agglutination. The aim of our work was to search for new ways to reduce the agglutination of spermatozoa in the preparation of freshly prepared sperm in the process of production of embryos in vitro. To eliminate the agglutination of spermatozoa in the semen preparation stage, we used GCY medium, followed by demolition of seed in SOFw environment, which has resulted in a significant (almost 15 times!) reduce of the number of bound sperm. In our opinion, a decrease in agglutination in GCY buffer was connected with a specific influence of the constituent components of sperm. Conclusion: Thus, our method of preparation of freshly prepared sperm for in vitro fertilization allows a sharp decline in sperm agglutination, which will improve the fertility of eggs during the production of embryos in vitro sheep
