Title

EFFECT OF DIETARY MELATONIN AND L-TRYPTOPHAN ON GROWTH PERFORMANCE AND IMMUNE RESPONSES OF BROILER CHICKEN UNDER EXPERIMENTAL AFLATOXICOSIS

Pages

  139-144

Abstract

 The aim of the present work was to determine whether the administration of MELATONIN or L-TRYPTOPHAN (a precursor of MELATONIN) affects the immune responses and PERFORMANCE of BROILERS during induced exposure to AFLATOXINs in feed. The study was conducted from 0-6 weeks comprising six dietary treatments in triplicate with 10 chickens in each replicate. The diets were formulated to supply 23% crude protein (CP) and 2800 kcal ME/kg in starter ration and 20% CP and 2900 kcal ME/kg in finisher ration. The experimental diets were offered ad libitum with free access to water throughout the entire experiment. Inclusion of AFLATOXIN in the feed at 0.5 mg/kg feed caused a significant reduction in the growth PERFORMANCE of BROILERS. Supplementation of MELATONIN (20 mg/kg in feed and 20 mg/kg body weight through i.p. route) or its pre-cursor (L-tryptophan at 250 mg/kg feed) in AFLATOXIN fed BROILERS resulted in numerically improved perform-ance. AFLATOXIN inclusion in the feed also caused a significant reduction in haemagglutination titer against sheep RBC and cell mediated immune responses to phytohemagglutinin (PHA-P) in BROILERS. MELATONIN or L-TRYPTOPHAN inclusion in toxin incorporated feed significantly improved both humoral and cell mediated IMMUNITY. No significant (P>0.05) differences were observed among various groups with respect to kidney and spleen weight but liver weight increased significantly (P≤0.05) and weight of bursa significantly decreased upon AFLATOXIN inclusion. Our study suggests that L-TRYPTOPHAN was partially as effective as mela-tonin in alleviating AFLATOXIN induced growth retardation and immunosuppression in broiler chicken.
