Research in: Agricultural & Veterinary Sciences

We conducted the research at the “Chinarli” poultry farm in Shamkir district. During the research, it was found that the application of the method of crossing local population Kuchinski breed chickens with roosters gave positive results, as the hatching rate of local population chickens increased by 10 percent and the egg production intensity by 6.13 percent. Egg productivity was 480 more. The use of Kuchinski roosters in crossbreeding during the maintenance of mixed-product local chickens had a positive effect on improving the breeding and productivity quality of local chickens. When summarizing the results, it turns out that during the 5-month laying period, 3750 eggs were collected from 30 hens in the experimental group and 3270 in the control group, that is, 480 more eggs than in the experimental group. The laying intensity in the experimental group was 70.0% at the beginning and 90.0% during the peak period of laying. In the control group, it was 64% and 77.0%, respectively. This corresponds to the characteristic features of the breed. The average weight of the egg was naturally higher in the control group. Thus, the chickens and roosters of the Silver Adler breed are heavier in terms of live weight than the roosters and hens of the Kuchinsky breed.
