Abstract
The aim of the conducted research was to study the effect of the combined ac-tion of probiotic strains of microorganisms and the "protected" form of choline in the form of an innovative feed additive KPKh (probiotic complex, choline) on the milk yield and milk composition of Dorper sheep.
Materials and methods. The studies were conducted in the Department of Physiology and Biochemistry of Farm Animals of the Federal Research Center for Animal Husbandry – Academician L. K. Ernst All-Russian Research Institute of Animal Husbandry and in Voskhod LLC, Kaluga Region. The object of the research were two groups of ewes with 5 heads in each group. The groups were formed based on the principle of pairs of analogues: I - control, II - experimental. KPKh was in-cluded in the diet of the experimental group at the rate of 20 g per head per day mixed with compound feed. Milk productivity of ewes in the experimental and control groups was determined by the lamb gain in 20 days. Milk composition was de-termined using a CombiFoss FT+ device (FOSS, Denmark) based on infrared spectroscopy and flow cytometry (protocols recommended by the manufacturer were used).
Results. Thus, the use of KPH promotes an increase in milk productivity of ewes by 8.98 % compared to the control group, which is interconnected with both the improvement of digestive and metabolic processes, according to the available research data on the physiological action of both the microorganism strains included in the complex of enzyme-probiotic strains and the innovative form of "protected" choline. A significant increase in fat content (+19.8 % in the first month and +24.0 % in the third) was revealed in the milk of ewes in the experimental group, with an improvement in the fatty acid composition, as well as dry matter (+7.02 % in the first month and +9.07 % in the third).
