A 6-week study was conducted to determine the effects of feeding diets containing commercial probiotic (Bioteksin-L, 2x10(8)cfu/g), antibiotic (Flavomycin) and dry yeast (Saccharomyces cerevisiae) performance, abdominal fat weight, carcass weight and carcass yield of broiler chicks. Four dietary treatments-control, containing 0.15% commercial probiotic (bioteksin-L), 0.15% antibiotic(Flavomycin) or 0.3%. dry yeast were randomly assigned to four groups of chicks. A significant increase in body weight gain, feed conversion rate and carcass weight of birds was observed in birds fed flavomycin and dry yeast at the end of 6-wk period (P<0.05). Biyoteksin-L and Saccharomyces cerevisiae supplementation to diets tended to decrease, abdominal fat weight and abdominal fat percentage (P<0.5).
