Abstract

An experiment was conducted to evaluate the effects of organic acids and PHYTASE ENZYMEsupplementation on IMMUNE SYSTEM and carcass characteristics of BROILER CHICKENS. Theexperiment was done in factorial arrangement 2×2×2 based on completely randomized designwith 8 treatments, 5 replicates and 12 chicks in each to 42 d of age. Diets including naturalvinegar (0 and 2%), CITRIC ACID (0 and 1%) and PHYTASE ENZYME (0 and 500 U phytase/kg offeed). All the birds were vaccinated against Newcastle disease by lasota vaccine via aye drop in11 and 23 days. In order to study the IMMUNE SYSTEM situation, blood samples of two birds ofeach replicate was taken in 42 day. After serum separation, the IgG of NDV was detected by HItest. One birds of each replicate (five birds of each treatment) randomly selected and were killedto evaluate lymphoid organs weigh and carcass characteristics at 42 day. The analysis of resultsshowed that addition of VINEGAR and phytase significantly increased the relative weight of bursa(P<0/05). Interaction effect of CITRIC ACID with VINEGAR and with PHYTASE ENZYME significantlyincreased the relative weight of bursa (P<0/05) also VINEGAR significantly increased the relativeweight of spleen (P<0/05). Phytase significantly increased the abdominal fat (P<0/05) whileCITRIC ACID and interaction effect of CITRIC ACID with VINEGAR significantly decreased theabdominal fat (P<0/05). In current study treatments hasn’t any effect on internal organs relativeweight (P>0/05).
