The effect of adding a synergistic mixture of the oyster mushroom Pleurotus ostreatus and beta-glucan to the diet in estimating the oxidation indices of the serum of Ross 308 broilers exposed to heat stress

Abstract

This study aimed to determine the effect of adding a synergistic mixture of oyster mushrooms and beta-glucan in estimating oxidative stress indicators in the serum of broilers exposed to heat stress. 300 one-day-old broiler chicks (Ross 308) were used and distributed randomly into four treatments. The control treatment (T1) was fed the standard diet without any addition. As for treatments T2, T3, and T4, their birds were fed with the diet added to the synergistic mixture at a rate of 0.5, 1, 1.5 g/kg feed for the starter diet. As for the final diet, the addition was 0.250, 0.5, 0.750 g/kg each of oyster mushrooms and the same amount of beta-glucan for the above treatments, respectively. It was shown from the results obtained that there was a significant increase (P<0.05) in the concentration of the enzymes SOD, G-PX and the enzyme CAT, and a decrease in the concentration of liver enzymes ALT, AST and the concentration of TBA for the treatments to which the synergistic thread was added, especially at the level of 1.5 gm/kg of feed and did not have any negative effect.
