The article presents the influence of microclimate parameters on the productivity of dairy cows. Keeping cows in a loose-box way with a better microclimate turned out to be more effective than keeping them in a tethered way. The temperature and relative humidity in this premise during the cold season were normal or closer to normal. In comfortable conditions, milk yield per cow was 6.4% higher and amounted to 23.8 kg against 21.8 kg.

It has been established that the use of the interval milking of goats producing biosimilar human lactoferrin leads to significant changes in the physicochemical and biochemical indicators of animal milk, namely, to an increase in fat content by 32% (P<0.001), total protein content – by 12% (P<0.001 ), MSNF – by 9% (P<0.001), density – by 18% (P<0.001), somatic cell content – by 81% (P<0.001), rhLF concentration – by 15.2-66.0% (P<0.001 0.001) compared to the initial period. Interval milking of goats producing recombinant protein promotes the activation of human lactoferrin production, which can be used to regulate rhLF production in monitoring the mammary gland status of transgenic animals.

The article presents data on the development of optimal parameters for the production and quality control of an inactivated emulsified vaccine for the prevention of salmonellosis in birds, the isolation and selection of immunogenically effective vaccine strains of Salmonella. The data on the isolation of pathogens for the formation of vaccine strains in the conditions of poultry farms of the Republic of Belarus are given. The importance and relevance of this work lies in the fact that the selection of vaccine strains, taking into account the circulating Salmonella strains in each individual endemic zone, is necessary to create the most immunogenically effective vaccines.

The objective of this work was to study the effect of Gentabiferon-B on the morphofunctional state of the organism of mice with Ehrlich ascites carcinoma (EAC) under the effect of doxorubicin. We studied the individual and combined effects of drugs on the concentration of tumor cells in the peritoneal cavity, as well as leukocytes and their individual populations in the blood of mice with EAC on day 10 of tumor growth; in addition, the longevity in the animals with a tumor was estimated after the use of doxorubicin and Gentabiferon-B. It was established that the combined use of drugs did not reduce the specific cytotoxic effect of doxorubicin in relation to tumor cells, which was assessed by the concentration of EAC cells in ascite. The number of tumor cells in the animals of this group was by 49.3% lower than the concentration of neoplasm cells in mice with EAC without treatment. In the experiment, an increase by 55.8% in the life expectancy of the animals treated with doxorubicin and Gentabiferon-B was observed relative to mice with a tumor after monotherapy with Gentabiferon-B. Combined drug therapy induced an increase in the concentration of blood lymphocytes by 39.5% relative to the number of these cells in mice with EAC after exposure to doxorubicin alone. The results obtained allows to assume that the efficacy of the antitumor activity of doxorubicin in its combined use with Gentabiferon-B and the immunomodulatory effect of Gentabiferon-B in conditions of tumor progression are preserved.

The article studies the patterns of morphological changes in the thyroid gland and adrenal glands in a newborn white-breasted hedgehog, which should be considered as a compensatory-adaptive reaction of the body aimed at maintaining metabolic homeostasis by the period of postnatal life. In 75% of cases, a definitive cortical substance was found, which is not accompanied by zonal differentiation. The chromaffin cells of the medulla are few in number, poorly differentiated, and are located in the center of the gland in the form of a thin strip. The thyroid gland does not have a typical lobular structure and classic follicles, it is represented by asexual accumulations of thyrocytes, which indicates its incomplete definitive structure.

The article presents materials on studying clinical and laboratory indicators of pregnant cows at 60 days of gestation, prone to the development of gestosis. In cows with the uterine fetal growth retardation syndrome at 2 months of pregnancy, subsequently complicated by gestosis, the established morphobiochemical changes indicate failures in the protein metabolism, functioning of the liver, kidneys, and the circulatory system. The changes also show an intensive accumulation of lipid peroxidation products, with a decrease in the activity of the enzymatic and non-enzymatic link of the AOD. The development of the fetal intrauterine growth retardation syndrome occurs against the background of a trophism disorders in the developing embryo. This at early stages of pregnancy is clinically manifested by a decrease in the size of the uterine horn cavity by 22.2-34.2%, the length of the fetus – by 41.5-48.9%, the body diameter – by 19.9-28.9%, the size of the corpus luteum of the ovary – by 15.7-24.1%.

There have been determined the optimal performance parameters for swine of maternal breeds used in pedigree swine breeding, based on selection and genetic techniques and methods. Analysis of the association of polymorphic variants of marker genes with reproductive, fattening and meat traits of sows has shown that the RYR1NN, ESRBB and ESRАВ, H-FABPHH and H-FABPdd genotypes have beneficial effects in the context of stress resistance, prolificacy, litter weight at weaning, average daily gain, feed expenditures per unit of gain, backfat thickness over the 6-7th thoracic vertebrae, the weight of backgammon. Molecular genetic testing of sows for these genes will make it possible to improve reproductive (by 13.3-21.0%), fattening and meat traits (by 2.7-10.8%).
