Feeding of young chickens of egg productivity under conditions of the Amur region with the use of biologically active additives

Abstract

Due to the need to increase poultry production with the lowest economic costs, there will always be a need for research on the use of new feed additives and means. The inclusion of such additives in poultry compound feed increases productivity, improves metabolism and makes feed more effi cient. The purpose of the work was to study the eff ect of Co, I, Se asparaginates and the Vitacell probiotic when they are separately and jointly included in compound feed on the growth, development, metabolism and productivity indicators of replacement young chickens of the egg productivity direction. The research was carried out in AO “Belogorskaya Poultry Farm” in the Belogorsky area in the Amur region. It was found that asparaginates Co, I, Se and the probiotic Vitacell positively aff ected the dynamics of the live weight of the replacement young chickens. When they were used together, the eff ect of exposure increased. Thus, in the 3rd experimental group with the highest livability of chickens the maximum absolute gain in live weight was recorded at 984,2 g versus 934,1 g in the control group. In the physiological experiment on the replacement young chickens, it was proved that asparaginates Co, I, Se and the probiotic Vitacell positively aff ected the digestibility of organic substances and the metabolism of N, Ca and P. When they were used together (the 3rd experimental group), the digestibility of organic substances, crude protein, fi ber and nitrogen-free extractive substances was signifi cantly higher than in the control group, the nutrient availability coefficients of N, Ca, P were maximum and amounted to 73,86 %, 44,20 and 46,82 %, respectively.
