The use of feed additives in the diet of egg productivity chickens

Abstract

Due to the need to increase poultry production obtained at the lowest economic cost, there will always be a need to research 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 eff ective. The purpose of the work was to analyze the use of feed additives in the diet of egg productivity chickens. In order to conduct the research, three groups of egg productivity chickens were formed: a control group and two experimental ones. Chickens of the 1st experimental group, in addition to the standard feed received the feed additive SibMos Pro in the amount of 0,1 g/kg live weight. For chickens of the 2nd experimental group the drug Immufon was added to the main diet in the dose 0,01 ml/ kg of live weight. It was established that the addition of the studied feed additives SibMos Pro to the diet of chickens in the 1st experimental group and the drug Immufon in the 2nd experimental group had a positive eff ect on the increase in live weight of chickens during the experimental period. Thus, the gain in live weight of one chicken diff ered between groups. The indicator ranged from 934,1 g in the control group to 964,0 g in the 2nd experimental group. The maximum gain in live weight was in the 2nd experimental group, where it was 3,2 % higher than in the control group. The reduction in feed consumption occurred due to better absorption of compound feed in chickens from this group, which was associated with the use of the drug Immufon, which promoted better absorption of feed nutrients. Thus, it was established that the highest productivity indicators were shown by chickens of the 2nd experimental group that received the drug Immufon, therefore we recommend that poultry farms with egg productivity use this drug in the compound feed for young animals at the dose of 0,01 ml/kg of live weight. We also recommend to use the feed additive SibMos Pro in the amount of 0,1 g/kg live weight.
