RESUMO
ABSTRACT The effect of egg powder inclusion in the pre-starter diet (1-7 days of age) on the performance, and intestinal morphology and microbiology of male broiler chickens was evaluated in a completely randomized design. Starter diets with equal metabolizable energy and crude protein levels were formulated to contain 0, 20, 40, or 60 g egg powder/kg diet. Results showed that body weight, feed intake, feed conversion ratio, and European efficiency index were positively affected (p≤0.05) by egg powder inclusion in the starter diet. Inclusion of 40 g egg powder/kg diet in the starter diet promoted the best performance results. Jejunal villus height and villus to crypt ratio increased (p≤0.05) and intestinal length decreased (p≤0.05) as a result of egg powder inclusion in the starter diet. Egg powder inclusion in the starter diet reduced (p≤0.05E. coli counts, but increased (p≤0.05) lactic acid bacteria counts in the small intestine. The results obtained in the present study indicate that the inclusion of 40 60 g egg powder/kg of starter diet g improved the performance and intestinal health of broilers.
