ABSTRACT
The influence of the Beluga feed material on the productivity of broiler chickens and on the quality of poultry products has been studied. The results of the study have shown that the use of the Beluga feed material had been favourable for the growth and development of broiler chickens during the entire period of research. In the period from 11 days of age, the live weight in the experimental group had increased, compared to the reference group (control), and this trend continued until the end of the experiment. On day 21, the live weight of broiler chickens in the experimental groups exceeded that in the reference group by 6.05% (P<0.05-0.001). On day 44, the live weight of broiler chickens in the experimental groups exceeded the live weight in the reference group by 7.99% (P<0.05-0.001). The absolute growth in both the groups of chickens for the first 10 days was almost equal, on day 44, the difference was 13.33%. The introduction of the Beluga feed material into the diets of broiler chickens in the amount by 5% increased the productivity and preservation rate of broiler chickens. The use of the Beluga feed material had a positive effect on the quality of the ready product. By the organoleptic characteristics, the meat of broiler chickens met the requirements of regulatory documents. The content of toxic elements in the leg and breast muscles in the reference and experimental groups did not exceed the maximum permissible concentrations. According to the research data, the mass fraction of sodium nitrite was not found in either of the studied samples. By the mass fraction of fat and protein, the experimental group significantly exceeded the reference group. The introduction of 5% Beluga feed material into the diet of broiler chickens reduced feed consumption by 23 g/kg of live weight, increased the live weight yield (for example, the weight of the eviscerated carcasses of the total number of chickens in the experimental group was higher by 5%, compared to the reference group), and had a positive effect on the development of the internal organs.
