EFFECT OF PROBIOTIC SUPPLEMENTED DIETS ON THE PERFORMANCE OF BROILER CHICKENS DURING THE RAINY SEASON

Abstract

This study was conducted to determine the effect of probiotic (Saccharomyces cerevisiae) supplemented diets on the performance of broilers chickens during the rainy season. Two hundred and fifty five broilers chickens were randomly allotted to five treatments in a complete randomize design (CRD) with three replicate per treatment, each replicate having 17 birds. Saccharomyces cerevisiae was included at 0%, 0.25%, 0.5%, 0.75% and 1% respectively. Feed intake was measured weekly and the birds were weighed once weekly. Data obtained from the study were subjected to Analysis of Variance and significances differences among treatment means were compared using the Duncan test. All parameters (final body weight, body weight gain, average daily gain, total feed intake, average feed intake and feed conversion ratio) measured show significance (P<0.05) difference. In conclusion, inclusion of baker's yeast in broilers diet improved growth performance of broiler chickens.
