Effect of Adding Taurine and Vitamin C on Physiological Performance and Antioxidant State of Broiler Chickens During Summer Season

Abstract

This study was conducted in animal production farm during in Collage Agriculture - University of Anbar during to aimed to study the effect of effect of adding taurine and vitamin C on physiological performance of broiler chickens during summer season. 180 one day unsexed hatched chicks will distributed into five treatments with three replicates for each treatment, as the following T1, control treatment, T2 adding 300 mg of vitamin C / kg diet, T3, T4 and T5 adding 300, 600 and 900 mg of taurine / kg diet respectively. The results showed there is no significant effect of adding taurine and vitamin C on total protein, albumin, uric acid, creatinine, glucose and Triglycerides as well as the addition of taurine and vitamin C to diet caused a significant decreased in AST, ALT and MDA compared with control treatment. AST enzyme level was 5.493 U/L in T1 compared with 4.630, 4.677, 4.387 and 4.234 U/L while the ALT level was 6.433 U/L and decreased to 3.933, 5.027, 4.033 and 3.383 U/L in T2-T5, respectively as well as MDA concentration was 0.1504 and 0.1127 and decreased to 0.0853 in T3 and 0.0968 in T4 and the highest decreased was in T5 treatment 0.0868.
