9 Padilo L.P., Gritchin A.V., Romanov N.I., Podshibyakin D.V. Retrospective geo-spatial analysis of ASF epizootics in the Saratov region in 2011 – 2018
This article presents the experience of using the geographic information system (GIS) for retrospective analysis of current epizootic situation on African swine fever (ASF) in populations of boars Sus scrofa and domestic pigs S. scrofa domesticus in Saratov Region during the period from 2011 to 2018. Using of geographic information systems (GIS) made it possible to present the analytical data obtained in a cartographic form and to demonstrate the dynamics of spread of ASF and the clustering of outbreaks in specific areas of the region. The total number of domestic pigs and wild boars that either died during this period or subjected to forced slaughter was 5141 heads. There were 122 ASF outbreaks among domestic pigs and 17 outbreaks recorded among wild boars. A large part (about 93%) of pig’s population covered by ASF was kept in backyards and farms with a small number of susceptible animals. It was found that the outbreaks of ASF, registered during the entire period of epizootic, formed three distinct spatial clusters. The first one was in the western part of the Region, on the territory of Turkovsky, Romanovsky, Balashovsky and Samoylovsky districts. The second one was in the central part of the Region (Voskresensky, Marksovsky, Volsky, Saratovsky and Balakovsky districts). And the third one was in Lysogorsky district of the Region. Key words: geo-information systems, spatio-temporal analysis, epizootic process, African swine fever.

In the dynamics of early pregnancy in cows, the change in blood concentration of interferon-tau and progesterone was studied. Their pathological significance in the manifestation of delayed development and death of embryos is shown. A biological and clinical assessment of bovine recombinant interferon obtained in the Belarusian State University is given when it is used as a means of increasing the effectiveness of insemination and prevention of embryopathy. The conclusion was made about the expediency of its use in the reproduction of cattle as a means of increasing the fecundity of the breeding stock. The proposed dose and patterns of use of the drug. Key words: cows, interferon-tau, progesterone, embryopathy, prevention.
42 Lazareva E.A., Kozlova A.D., Krasnikova M.S., Borunova S.M., Yatsenyuk S.P. Screening studies of bovine semen by PCR for pathogens detection
The use of technology of artificial insemination of cattle leads to an increase in the potential risks of the spread of infectious diseases. The article presents the study of 444 samples of frozen semen of bulls from domestic and foreign breeding farms for the presence of genome of the 22 infectious agents by PCR. None of the samples revealed DNA (RNA) of microorganisms of the genus Brucella, Leptospira, Chlamydia, Neospora caninum, Bovine coronavirus, Lumpy skin disease virus, Bovine parainfluenza 3 virus, Bluetongue virus, Schmallenberg virus and Bovine leukemia virus. Pseudomonas aeruginosa, Proteus spp., Staphilococcus aureus DNA were detected in semen samples. The analysis showed a high frequency of Mycoplasma spp. DNA (71,2 %), Campylobacter spp. (66,9 %) as well as DNA of Histophilus somni (73,9 %). Some species of Campylobacter and Mycoplasma, as well as Histophilus somni, are considered common inhabitants of the genital tract of bulls. At the same time, some strains of H. somni and some species of Mycoplasma (M. bovigenitalium, M. californicum, U. diversum) can cause various diseases in cattle. Of greatest interest is the detection in the semen DNA of Bovine herpesvirus type 1 (0,9 %) and Bovine herpesvirus type 4 (0,7 %), RNA of Bovine viral diarrhea virus (0,5 %) and also DNA of Coxiella burnetii (7,2 %), Campylobacter fetus (0,7 %) and Mycoplasma bovis (1,6 %). The results indicate the necessity of optimization the control system of breeding material used for artificial insemination to prevent the spread of infectious diseases. It should be noted that pathogens such as Bovine viral diarrhea virus, Coxiella burnetii and Mycoplasma bovis were found only in semen samples from foreign breeding centers. These data point to the need to tighten the requirements for bull semen coming from foreign farms. Key words: artificial insemination, bovine semen, pathogens, PCR.

To increase the overall resistance of quails, their productivity, as well as the quality of meat due to the normalization of metabolic processes, various feed additives are used. Authors studied the effect of feed additives Abiopeptide and Ferropeptide (A-BIO, Russia), which contain protein hydrolysates manufactured by on the quality, safety and sanitary and veterinary indicators of quail meat. It was found that quail meat, which used these feed additives, safe, non-toxic, had high biological value and corresponded to benign food products by all parameters regulated by regulatory documents (GOST 51944 – 2002; SanPiN 18.104.22.1688-01). Key words: safety, protein hydrolysates, veterinary-sanitary expertise, meat, poultry, quail.
54 Reznichenko L.V., Nikolenko E.N., Noskov S.B. Development of Histological Methods for Sour Cream Adulteration Detection
There are various types of adulteration at the sour milk product market currently, what, as is known, results in low nutritional and biological value of the product and may be potentially dangerous to human health. The product often exposed to adulteration is sour cream, which is in strong consumer demand. Kefir, nonfat cottage cheese, vegetable oil, soy protein, stabilizers, flavouring agents are added to sour cream. But it is particularly difficult to identify carrageenan, guar gum and modified starch in this product. The aim of our work is the development of histological methods for determination of carrageenan, guar gum and modified starch in sour cream. As a result of conducted studies, for the first time a histological method was developed, which can detect inadmissible admixtures, such as carrageenan, guar gum and modified starch, in sour cream to a high precision. The developed method will give the opportunity to detect food adulteration and unscrupulous producers of sour cream and other sour milk products. Key words: sour cream, kefir, cottage cheese, adulteration, carrageenan, modified starch, guar gum, histological tests.
