Abstract
The aim of this experiment was to know the internal organs size of 6-weeks old native chickens after supplement addition with l-threonine and l-tryptophan in the feed. A total of 112 native chickens a week-old were used in this experiment. The experiment was designed as a randomized complete block with four treatments and four replications. The dietary treatments were: T0 (control feed without supplementation of l-threonine and l-tryptophan); T1 (supplementation of 0.35% l-threonine and 0.10% l-tryptophan); T2 (supplementation of 0.68% l-threonine and 0.17% l-tryptophan); T3 (supplementation of 1.00% l-threonine and 0.25% l-tryptophan). The data collected were body weight, liver, pancreas, gizzard, and intestinal length of native chickens aged 6 weeks. The statistical analysis showed that supplementation of l-threonine and l-tryptophan gave significant effect (P<0.01) upon body weight, liver weight, pancreas weight, gizzard weight and intestinal length. It can be concluded that supplementation of 1.00% l-threonine and 0.25% l-tryptophan give the highest body weight and internal organs size of native chickens.
