Studying the young cattle bioenergy potential in the scapula and shoulder area in connection with the age of animals has revealed the regularity of the undulating biopotential growth in animals aged 1 to 12 months. From the data obtained during the research it can be concluded that during this period of life the organism of young cattle undergoes a number of significant changes in both morphological, physical and bioenergy development.

The results of field research conducted on soddy-podzolic light loam soil in the Vologda region established that the use of fertilizers significantly increased the yield of winter rye grain both against the background of the flavobacterin biofungicide and without its use. Depending on the doses of fertilizers and bacterialization with a microbiological preparation, the productivity of straw of winter rye naturally increased, the content of nitrogen, phosphorus, potassium in the production increased, the collection of crude protein by grain and the productivity in feed units increased.

The study on the therapeutic efficiency of drugs on anthelmintic such as al’vet, febtal granules, univerm, panacur pasta, equisect paste for nematodes in horses on the basis of the agricultural production cooperative “Breeding Stud Farm” “Vologodskij” and the Microbiology and epizootology chair of the Vologda State Dairy Farming Academy was presented.

The article discusses the results of scientific and economic experiment carried out on black-motley breed cows on the use of mineral and energy supplement, ‘Reactor’, which includes energy components, calcium propionate, betaine and natural sorbent. The complex action of the investigated product had a positive impact on animal productivity. It was established experimentally that using during the transitional period of 250-350 gr. of ‘Reactor’ per head daily allows to increase daily milk yield of cows in the first hundred days of lactation by 9.8 and 14.5% (to 30.3 and 31.6 kg vs.
