Цинк в форме органического соединения в кормлении молодняка крупного рогатого скота

In the process of increasing the efficiency of livestock production, great attention is paid to feeding balanced in vitamins, minerals and biologically active substances. With increasing productivity there is an intensification of metabolic processes in the body of animals, which are greatly influenced by microelements, the lack of which in the diet adversely affects the health and life expectancy of the animal. To compensate for this deficiency, feed additives are widely used, which have a comprehensive positive effect on the entire body. The aim of the work was to study the regularities of digestive processes in the rumen and metabolism in the body of young cattle fed an organic zinc compound. In the course of research, it was found that the use of an organic form of zinc instead of zinc sulphate in the amount of 50 %, 75 and 100 % in the diets of young cattle of 9-12 months of age allowed increasing the productivity of animals by 1.3-3.7 % with a decrease in feed costs for weight gain by 0.7-2.0 %.
