Meat qualities of cross cobb-500 broilers grown with the use of the antioxidant dihydroquercetin

Abstract

The Research is devoted to the study of the effect of the biologically active additive “Dihydroquercetin” in the compound feed on the indicators of meat productivity of broiler chickens. The results show that the increase in live weight of chickens that received dihydroquercetin in addition to the main ration was ahead of their control peers by 11,91-32,78 %. During the 40-day period of growing broilers, in the experimental groups with the addition of dihydroquercetin, they had a live weight of 15,22-50,51% more. From the beginning of fattening to the age of 40 days, the absolute and average daily growth rates showed a steady upward trend, then there was a decrease in the growth rate of chickens. The greatest effectiveness of the drug was noted at the beginning of the experiment, which indicates a positive corrective effect of the antioxidant on metabolism and an increase in the level of assimilation processes in the body of broilers. Up to 10 days of age, the chickens of the experimental groups receiving dihydroquercetin had higher relative growth rates, which obviously characterizes their better adaptation to the conditions of the experiment. The magnitude and nature of changes in the relative increase in live weight of broilers with longer cultivation up to 60 days of age indicate its inexpediency-even when using the drug dihydroquercetin, due to the unprofitability of its further use, and the lack of recoupment of costs for the purchase. In general, the higher studied indicators during the experiment were observed in broiler chickens of the III-IV experimental groups, the best result was shown in the group of birds receiving dihydroquercetin Supplement at the level of 1 g/100 g of feed, which allows us to consider it optimal.
