Changes in the metabolism of lactating goats of the Saanen breed under the influence of stimulating BAS

Abstract

Purpose: to study the effect of complex biologically active additives based on a protein hydrolyzate together with an iron-containing preparation on the metabolism of lactating goats of the Saanen breed according to the physiological and biochemical status of blood and the physicochemical properties of milk from animals grown in an industrial complex. Materials and methods. In the experiment, 45 Saanen goats were used, of which 15 goats were combined into the control group, 30 equally divided into two experimental groups. Experimental animals in addition to the standard diet received a biological supplement based on protein hydrolyzate, 40 ml/day. and iron-containing preparation "Bio-iron with trace elements" 10 ml / day. An experimental group of 15 heads received the drug "Abiotonic", another group of 15 heads - "Abiopeptide" (hereinafter, the subgroups "ABT + BfM" and "ABP + BfM"). Animals received dietary supplements in the complex, according to the following scheme: 30 days with a break of 5 days after 10 and 20 days, i.e. In general, the experiment lasted 45 days. To assess the condition of the control and experimental goats, blood and milk were taken (before the start of the experiment and at the end of the experiment). Physiological and biochemical blood parameters of goats were determined, which characterize protein metabolism - the level of aspartate aminotransferase (AST), alanine aminotransferase (ALT), total protein (OB), albumin (A), globulins and urea (M); lipid metabolism - the level of cholesterol (X) and triglycerides; carbohydrate metabolism - glucose level (G); energy metabolism - creatinine level (K); mineral metabolism - the level of phosphorus (P), chlorine (Cl) and iron (Fe). Milk was taken in the morning milking, examined for physical and chemical parameters: fat, protein, dry skimmed milk residue (SOMO), somatic cells and density. Results. It is shown that the use of these dietary supplements in lactating goats affects the physiological and biochemical status of blood and the physicochemical properties of milk. It is noted that the beneficial properties of additives are aimed at enhancing the catabolic processes of the body of goats, they are most effective in combination with vitamins and microelements, contributing to an increase in productivity while maintaining the internal reserves of the body. It should also be noted the effectiveness of the iron-containing preparation "Bio-iron with microelements", used in feeding lactating goats.
