Influence of biologically active additive succisilin on the growth and development of replacement heifers during the milking period

The aim of the study is to study the effect of the biologically active additive Succisilin on the growth and development of heifers during the dairy period. In the course of scientific experiments, scientific and economic experiments were conducted from birth to 6 months of age on red-mottled heifers. During the use of various dosages of this supplement, a positive effect on the growth and development of chicks was revealed. During the 6 months of the experiment, the live weight of heifers in the experimental groups increased by 2.3-4.3 %. The average daily gains were 26 g more in the first experimental group and 32 g more in the second experimental group in relation to the control group. The development of chicks, judging by the body build indices, were better in the experimental group.
