Effect of beta-glucan on the organism of broilers

Our studies are devoted to the search for new drugs with antioxidant, antihypoxant, immunomodulatory effects in order to increase the productivity of poultry. Due to the fact that beta-glucan has not previously been studied on poultry, before determining the effective therapeutic range of its doses, it is necessary to study the effect of a conditionally therapeutic dose of the drug on the body. A conditionally therapeutic dose - hereinafter - means the average therapeutic dose of a drug offered by the manufacturers of the respective drugs, calculated for humans (mammals).The main purpose is to study the effect of beta-glucan on meat productivity, morphological, biochemical indices of blood. In the experiment we used clinically healthy young hens of meat breeds of three months of age of the “Cobb 500” cross. The broilers of the first group (n = 9) were not prescribed the drug, they served as controls; the second group (n = 9) were given beta-glucan at 10 mg/kg body weight, corresponding to 125 g/t of food, for 14 days. The use of beta-glucan was accompanied by an increase in the average daily body weight, gain by 4,9%, slaughter yield by 1,5%, a significant increase in blood erythrocyte content by 32,6% on day 7, monocyte level by half, a decrease in total bilirubin by 21,0%, and a decrease in blood malonic dialdehyde by 10,8% on day 14. Cumulatively all data collected indicates positive effect of beta-glucan on meat productivity, morphological composition of blood broilers and metabolism in organism and prospects of its use in poultry industry
