Effect of different growth promoters on growth and meat yield of broilers

A total of 180 day-old straight run Arbor Acre broiler chicks were fed ad libitum diets without or with growth promoters such as, flavomycin, surmax (avilamycin), genex and availa-Z/M at 65mg, 100mg, 2g and 1g per kg respectively, up to 42 days of age to evaluate the efficacy of different growth pro...

Zusammenfassung:A total of 180 day-old straight run Arbor Acre broiler chicks were fed ad libitum diets without or with growth promoters such as, flavomycin, surmax (avilamycin), genex and availa-Z/M at 65mg, 100mg, 2g and 1g per kg respectively, up to 42 days of age to evaluate the efficacy of different growth promoters and recommend a suitable growth promoter in broiler diet. The results indicated that live weight and feed conversion ratio differed significantly (P0.01), and it was observed that surmax group was the best performer among the dietary groups. The study also reveals that antibiotic groups (flavomycin and surmax) were better in terms of growth and meat yield compared to the non-antibiotic groups (genex and availa-Z/M). Livability was apparently higher in surmax group (100%) compared to other groups. Profitability ($/kg broiler) was found 0.225 (Tk.15.21), 0.269 (Tk.18.28), 0.309 (Tk.21.01), 0.242 (Tk.16.44) and 0.231 (Tk.15.68) in control, flavomycin, surmax, genex and availa-Z/M groups, respectively. Dressed yield and breast meat of broiler were increased in surmax groups. Abdominal fat in female was increased (P0.05).
