Title

EFFECT OF VITAMIN PREMIX REDUCTION ON MEAT QUALITY AND INTERNAL ENZYMES DEFICIENCY INDEX OF BROILER CHICKENS FED DIETS BASED ON WHEAT AND BARLEY IN CAGE SYSTEM

Pages

  53-61

Abstract

 This experiment was conducted to evaluate the effects of reduction VITAMIN PREMIX between 29 and 42 day of age in BROILER chickens fed diets based on wheat and barley on performance and MEAT QUALITY. A total 112 male BROILER chicks (Ross 308) were allocated to 7 treatment groups, with 4 replicates per each treatment and 4 birds per replicate pen. Feed intake and weight gain were measured at 35 and 42 days and feed conversion ratio was calculated. At days 35 and 42 of ages, one bird from each replicate was bled, to determine the enzymes aspartate amino transferase (AST) and alkaline phosphatase (ALP) as an indicator for lacking of vitamins E and B6. The slaughtered and measured tissue antioxidant (TBARS) were frozen for 6 months. The results of this trial showed that there were no significant differences in performance and aspartate amino transferase with reduction or withdrawal of VITAMIN PREMIX from diets in 29-35 days. However, there were significant differences between the treatment without VITAMIN PREMIX (T1) and other treatments for these performance and aspartate amino transferase in 36-42 days of age (P<0.05). The results of thiobarbituric acid reactive substances (TBARS), ALP showed there were significant differences between the treatment without VITAMIN PREMIX (Tl) and other treatments for these TBARS value and ALP in 35 day of age (P<0.05). Also, TBARS values showed the significant differences between the treatments without VITAMIN PREMIX (TI) and 33% VITAMIN PREMIX and other treatments for birds slaughtered at 42 days of age (P<0.05). In conclusion, the results of the present study indicated that in the battery CAGE system it is possible to reduce dietary VITAMIN PREMIX (66%) during finisher period but withdrawal can negatively affect the performance and MEAT QUALITY of BROILER chickens.
