МИКРОЭЛЕМЕНТНЫЙ СОСТАВ МЫШЕЧНОЙ ТКАНИ ЦЫПЛЯТ-БРОЙЛЕРОВ НА ФОНЕ ПРИМЕНЕНИЯ КОМПЛЕКСНОЙ КОРМОВОЙ ДОБАВКИ

Abstract

The results of the influence of "Zaslon 2+" complex feed additive on the content of microelements in the muscles (breast, femur, lower leg) of broiler chickens of Ross 308 cross are presented. Two groups of birds were formed, each contained 100 birds. Birds of the control group were fed with the main ration. The main ration in the experimental group was used in combination with "Zaslon 2+" complex feed additive throughout the entire period of the study. Positive effect of the complex feed additive on concentration of microelements in the muscle tissue of broiler chickens was noted throughout the experiment. Thus, the level of iron in pectoral muscles of the birds of the experimental group increased by 9.1%, copper - by 6.7%, zinc - by 6.9% on the 38th day of the experiment, in comparison with the control group. The concentration of iron in femoral muscles of broiler chickens after application of the feed complex was higher by 18.1%, zinc - by 16.2 in relation to the parameters of the control group. The content of mineral elements in leg muscles of broiler chickens from the experimental group was higher than their concentration in the muscles of the birds from the control group. So the level of iron was higher - by 27.6%, copper - by 23.1%, zinc - by 11.8%. An increase of the content of microelements in the muscle tissue of birds indicates a positive effect of the components that make up the complex of additional nutrition.
