ABSTRACT
The adequacy of dietary energy is crucial for optimizing the performance of local chickens, promoting optimal growth while minimizing abdominal fat deposits. Amino acids can influence growth and are linked to energy synthesis through metabolic feedback mechanisms. This study investigated the effects of a low-calorie diet supplemented with various amino acids (valine, serine, tryptophan, and arginine) on local chickens’ ileum morphology and growth. Three hundred and fifty day-old Sentul chickens were randomly assigned to 35 experimental groups, each containing ten chickens. The study involved five different dietary treatments: P1: 2417 kcal/kg; P2: 2590 kcal/kg; P3: 2417 kcal/kg with amino acids; P4: 2590 kcal/kg with amino acids; and P5: 3178 kcal/kg. The chickens were fed these diets for eight weeks, from one day to eight weeks old. The results indicated that a low-calorie diet affected (P<0.05) the morphology and growth of the ileum and its cells. However, the group receiving a low-energy diet of 2590 kcal/kg supplemented with amino acids experienced enhanced growth of ileum and villi cells.
