Abstract

This experiment was conducted to evaluate the effectof a yeast extract product on broiler growth performanceand carcass traits. A total of 810 male Ross broiler chickswere distributed in 27 pens (30 birds per pen) in a completelyrandomized design. The animals were fed the experimentaldiets from 1 to 42 days of age. Treatments consisted offeeding a T1) basal corn-soybean meal diet; T2) a dietcontaining 2% yeast extract from 1 to 7 days of age and T3)a diet containing 2% yeast extract from 1 to7 and 38 to 42days of age. Better growth performance was observed inbirds fed yeast extract from 1 to 7 and from 38 to 42 days ofage. Carcass traits were not statistically influenced by thedietary treatments. KEY WORDS: Body weight gain, feed conversion, feed intake, organs.
