Influence of adsorbent on the productive qualities of Ross 308 parent flock chickens

   The research was conducted to evaluate the effectiveness of using the Mustala adsorbent in feeding chickens of the parent flock of the Ross 308 cross. The work was carried out at an enterprise for raising a broiler parent flock. A control and experimental group of hens of the parent flock of the Ross 308 cross were formed at the age of 40 weeks (in the control group - 9303 heads, in the experimental group - 9278) with floor housing. The birds in the experimental group were fed Mustal adsorbent at a dose of 1.5 kg/t of feed; the drug was not included in the diet of the birds in the control group. During the growing period, the leading zootechnical indicators were determined: gross harvest, hatching harvest, number of commercial chickens, and safety, which were calculated according to generally accepted methods in poultry farming. It was found that the birds of the experimental group exceeded the control group in terms of the gross number of eggs and the yield of hatching eggs by 0.24 and 0.20 %, respectively. Mustala adsorbent made it possible to increase the yield of commercial chickens by 0.8 % and increase safety in the experimental group by 0.02 %. Profit from product sales in the experimental group is 2.21 % higher than in the control group.
