The article presents comparative results of production tests of zeolite-containing feed additives based on tripolite. The introduction of various additives in mixed feed as well as the resulting products quality is accompanied by zootechnical and veterinary-sanitary control. According to the data of the slaughter and deep processing shop, the best meat indices were obtained from poultry of the 2nd experimental group (poultry house No. 110). In general, the introduction of new zeolite-containing additives “Belasorb” and “MeKaSorb” into the broiler chickens diets in the norm of 2.0% of mixed feed contributes to the development of meat qualities and an increase in the 1st grade carcasses yield – by 12.9-14.7 p.p., the weight fraction of the breast – by 1.2-1.3 p.p. and of the thigh – by 0.2-0.3 p.p., the offal set yield – by 12.7-14.7% of the actual weight, an increase in the yield of muscle – by 0.78-0.99 p.p. and of pulp – by 0.59-0.77 p.p. The dietary properties of meat in the experimental groups increased – by 3.5-4.5%. |
