The results of growing meat bulls

Abstract

The article presents the results of a scientific and economic experiment to assess the meat productivity of Kazakh white-headed bulls in the conditions of Southern Russia. he fattening of the bulls lasted until the age of 15 months. During the fattening period, the animals of the experimental group surpassed the peers of the control group according to indicators of meat productivity. By changing the conditions of feeding and keeping calves at different age stages of their development, a person forms in them those vital functions, organs and tissues that most contribute to ultimately obtaining the greatest amount of high quality milk and meat productivity in adulthood. The paper presents the results of growing bulls of the Kazakh white-headed breed up to 15 months of age using the probiotic Prolaxim-V feed additive to obtain meat raw materials that meet the requirements for the production of food for children of early age. The use of a probiotic feed additive made it possible to increase the live weight by the end of the experiment by 8.65% (P < 0.01), the slaughter yield by 1.95 absolute percent, and reduce the incidence rate of the gastrointestinal tract.
