Total isoflavones extracted from red clover were supplemented in diets (4.38 mg/kg feed) of male Redbro broilers (45-56 days of age, n=30). Body weight gain and feed conversion improved by 5.1% (P>0.05) and 9.2% (P>0.05). Slaughter results showed that abdominal fat pad and ratio of abdominal fat pat to carcass weights of comb and testis to body weights markedly increased (P<0.05). Serum testosterone levels increased by 35.9% (P<0.05), the analysis of correlation of paraffin sections of testis also indicated that the total isoflavones could promote the development of the reproductive organs of male broiler chickens.
KEY WORDS: isoflavone, broiler, growth, testosterone
