ABSTRACT

Two experiments were conducted in order to study the response of 7-28 or 0-28 day old broilers to diets with different levels of energy, protein and lysine. The first experiment included 12 treatments with four replicates each, and a total of 480 seven-day old broiler chicks. The experimental design was the "San Cristobal" type of response surface. Results showed no significant differences among treatments for body weight gain. However, a significant difference (P‹ 0.01) was observed when a linear regression analysis was used. It was found that body weight gains were influenced linearly by the energy level in the diet. For feed consumption there were significant differences for lysine and protein levels, but not for energy levels. Significant differences were observed for feed efficiency among treatments due to protein, lysine and energy. In the second experiment, 480 broilers were fed diets with 3000 Kcal ME/kg of feed and different levels of protein and lysine. Statistical analyses were conducted using a completely randomized design, linear regression with 12 treatments and four replicates of 10 chicks each. After 28 days, results showed no significant difference (P › 0.05) among treatments for body weight gain due to protein level, but for lysine levels the differences were significant (P ‹ 0.01). No significant difference for feed consumption was observed among treatments, nor for feed conversion (P › 0.05) due to protein levels, but there was a significant difference due to lysine supplementation.
