The results of physiological experience when feeding premix based on “Gorlinka” concentrate to laying hens
The article presents the results of physiological experience on the use of premix based on protein-containing feed concentrate “Gorlinka” for laying hens of the parent flock. The studies were conducted on the basis of a second-order breeding company LLC Svetly, Svetloyyarsky District, Volgograd Region. In the course of physiological studies, a positive effect of the developed premix was revealed on the digestibility of the nutrients of the feed, as well as on the use of nitrogen, calcium and phosphorus by the poultry organism. Thus, the introduction of premix P1-2G resulted in an increase in dry matter digestibility factor compared to the control by 2.07%, crude protein by 1.88%, crude fiber by 1.07%, and crude fat by 0.97% . The use of nitrogen from the adopted chickens was higher in the experimental group by 1.39%, calcium - by 0.48%, phosphorus - by 0.50%. Hematological parameters were within the physiological norm, which indicates a normal course of metabolic processes in the body of laying hens.
