Effect of Dietary Probiotic, Organic Acid and Antibiotic Supplementation to Diets on Broiler Performance and Carcass Yield

Muzaffer Denli, Ferda Okan and Kemal Celik    

Abstract: The specific aim of this study was to determine the effects of the supplementation of separate probiotic (protexin), including organic acid combination, plant extracts, mineral salts (genex) and antibiotic (flavomycin) to broiler diets on performance, abdominal fat weight, abdominal fat percentage, liver weight, intestinal weight, intestinal length, intestinal pH, carcass weight, carcass yield of broiler chicks. In this study, 84 one-day old male broiler chicks were used and divided equally into 6 groups. When the control group was fed a diet without supplemented diet probiotic (0.1% protexin), organic acid (0.2% genex), probiotic + organic acid (0.1% protexin + 0.2% genex), antibiotic (0.15% flavomycin) and antibiotic + organic acid (0.15% flavomycin +0.2% genex) were added to the diets of the experimental groups respectively. The experimental period was 42 days. The results obtained in the experiment showed that the group receiving 0.15% flavomycin + 0.2% genex supplemented in the basal diet was exhibited higher body weight gain, feed intake and carcass weight and better feed efficiency respectively than the control and other groups (P<0.05). However liver weight, intestinal pH, and abdominal fat weight were not affected significantly by probiotic, antibiotic and organic acid treatments (P>0.05).
