Abstract
Abstract
The aim of the studies was to evaluate the effect of adding sodium dimethyl glycinate in broiler diets, as part of a feed additive to increase the digestibility of feed nutrients, improve health and increase the meat productivity of broilers. During the experiment, the prevalence of live weight was established by 77 g (3.81%) in the experimental group, with a reduction in feed costs per 1 kg of gain by 0.05 kg. Safety in the experimental group was 100%, and in the control - 97.5. The European efficiency index increased by 35.18 points and amounted to 389.35. An increase in the digestibility of nutrients obtained from feed by the body of broilers: dry matter - by 1.44, protein - by 1.25, fat - by 2.74, nitrogen-free extractive substances - by 1.67%. The mass of the pectoral muscles increased by 78 g, which confirms the high digestibility of nutrients in the feed. Sodium dimethylglycinate has also been shown to improve the immune system and reduce oxidative stress in broiler chickens. Activation of enzymes of the antioxidant status was observed under the influence of the studied additive: superoxide dismutase by 8.32%, ceruloplasmin by 9.47%, and the level of malondialdehyde decreased by 5.63%.
