چکیده
Biotin (B7) acts as an antioxidant, as it inhibits the effect of many free radicals that are naturally formed within the body of the organism. This study aimed to find out the effect of adding different concentrations of biotin to the diet of broilers exposed to oxidative stress in improving productive and physiological performance. 180 unsexed Ross-308 one-day age chicks of broiler chickens were used, and they were reared together until the age of 7 days. Then the chicks were randomly distributed into 5 treatments, each treatment included 3 replicates, 12 chicks for each replicate. Oxidative stress was induced by adding 0.5% H2O2 to drinking water. The first treatment T1 (control) was free from adding B7 or H2O2, the second treatment (T2): a positive control treatment free from adding vitamin B7 + water added to it H2O2 at an average 0.5%,The third treatment (T3): adding 550 micrograms of B7/kg of feed + water added to it H2O2 at an average of 0.5%,Fourth treatment (T4): adding 650 micrograms/kg of vitamin B7 + water added to it H2O2 at an average of 0.5%,Fifth treatment (T5): Adding 750 micrograms of vitamin B7/kg of feed + water added to it H2O2 at an average of 0.5%. The results of adding vitamin B7 to the diet of T4 and T5 birds exposed to oxidative stress showed a significant increase (P<0.05) in the average live body weight, total weight gain and cumulative feed consumption average, and the best cumulative feed conversion ratio for treated birds (T3, T4, T5). compared to the rest of the treatments, Also, all addition treatments of vitamin B7 recorded a significant decrease (P<0.05) in the concentration of glucose, cholesterol, triglycerides, as well as in the low-density lipoproteins (LDL) and the level of Malondiadehyde (MDA) and a significant (P<0.05) increase in the concentration of high-density lipoproteins (HDL) and total protein compared with the rest of the treatments, also the serum of T5 treated birds showed a significant increase (P<0.05) in the concentration of glutathione peroxidase (GSH-Px) compared to all treatments.
