Influence of different dosages of selenium yeast in the diets of laying hens cross lohmann brown on metabolic indices and egg productivity

Abstract

There was implemented the research on the study of the effect of different doses of selenium organic preparation Selenium Yeast on nutrient digestibility of the diet substances, morphological, biochemical parameters and mineral composition of blood, and egg productivity. According to the principle of analog pairs, there were formed 4 experimental groups, each of which received a certain dosage of the preparation with a daily ration. The research has given the results that addition of Selenium Yeast at a dose of 150 grams per ton of compound animal feedstuff of laying hens enhances digestibility of nutrients, normalizes homeostasis parameters, increases egg production and egg weight, and improves morphological parameters.
