Biochemical status of the blood of chicken-broilers at the scramming of the stern mixture "Pular"

On the basis of the St. Petersburg State Academy of Veterinary Medicine, we carried out the research on the new feed mix "Pular" with the feeding of broiler chickens and its’ effect on the biochemical status of the blood of birds. For the experiment, 3 experimental groups of broiler chickens "Ross-308" were formed according to the principle of analogues (cross, age, living weight, development), 10 heads in each. Conditions for maintenance and feeding for all groups were the same. The main ration of the chickens was full-fat PK-6 feed mix, the chickens of the second experimental group additionally received 60% of PK-6 and 40% of the new feed additive Pular in addition to the feed mix, and third group - 10% of PK-6 and 90% of the new feed additive Pular. The experiment was conducted during 3 weeks. An increase in the total protein in the blood serum was detected while analyzing the biochemical parameters of blood, which indicates the activation of protein metabolism, an increase in the amount of calcium and phosphorus, indicates better absorption by the body, an increase in cholesterol in the second and third experimental groups by 30, 42 - 37.74% in comparison with the control indicates an increase in the level of metabolic processes, an increase in the concentration of the ALT enzyme by 4.18% and a decrease in the AST content by 19.73-22.95% in the second and third experimental subjects groups in comparison with contacts. The increase in the level of diene conjugates, dienketones in the blood serum of broilers receiving the feed "Pular" indicates activation of the processes of free radical oxidation, a decrease in the amount of MDA indicates a faster evacuation of harmful metabolic products and effective work of the antioxidant system of protecting the body of the bird. A study of the biochemical composition of the blood showed that the inclusion of the feed additive "Pular" in the broiler diet did not adversely affect the bird's organism, all the blood indicators were within the limits of the referent amounts.
