THE EFFECTS OF THE COMBINATION OF ARGININE AND TRYPTOPHAN ON GROWTH PERFORMANCE IN BROILER CHICKENS CHALLENGED WITH INFECTIOUS BURSAL DISEASE VACCINE

To explore the effects of the combination of tryptophan (Trp) and arginine (Arg) on growth performance of broiler chickens challenged with intermediate plus strain of infectious bursal disease virus vaccine, an in vivo experiment was conducted. A corn-soybean meal based diet containing different levels of Arg and Trp was used. Cobb155 male broiler chickens from 5 to 79 days of age were subjected to a diet supplemented with the combination of Trp and Arg. Forperformance, feed intake and body weight gain recorded weekly. Addition of Arg and Trptreatments into the diets significantly (P<5051) decreasedfeed:gain ratio. These findings suggest that the combination of Arg and Trp has a regulatory effect on growth performance.
