In: Journal of Agricultural Research Tanta Univeristy 2004.v.30(2)Summary: The effect of encapsulated lysine (Lys) and methionine (Met) on the performance of buffalo ca1ves was investigated. Fifteen male buffalo calves were used in this study. Calves were weaned early at 45 days of age. At weaning, the animals were divided into three groups similar in number and weight. Three groups were fed the same starter meal, but the second and third groups were supplemented with encapsulated Lys and Met. The second group was supplemented with four levels of lysine only (0.0, 7.5, 11.5 and 14.5 g/d), while the third group was supplemented with the same levels of Lys plus 3.5 g Met. Digestibility and nitrogen balance trials were carried out on three animals from each group at the seventy-day of the age. The results showed that daily gain and feed efficiency of the supplemented calf groups with Lys and Lys plus Met were higher than that qf calves in control group. Dry matter and crude protein digestion and nitrogen balance of the supplemented groups were higher than the control group. Our results suggested that Lys and Met addition led to improve the performance of early-weaned buffalo calves. Key words: buffalo, calves, lysine, methionine, performance and digestibility.
