The analysis of the obtained results shows that the reduction of the protein fraction in the feed, which is not amenable to assimilation, with the simultaneous replacement of the mineral (inorganic) premix with its citrated form, has a positive effect on the intensity of metabolism in the body of laying hens in the process of synthesis of egg components. A decrease in the amount of nitrogen and bioelements in the litter, and therefore the amount of their emissions into the environment, was established. It was experimentally confirmed that the optimal introduction into the diets of laying hens of the innovative protein concentrate "Proglot" in the amount of 19%, high-protein feed yeast in the amount of 3.5% and nanocitrates of bioelements in the amount of 25% of their content in the diet in the form of inorganic salts is optimal. The feasibility of using the additive “Water-soluble complex of fatty acids ELC” in feeding broiler chickens and quails has been proven. Product Description popup.authors Olha M.
