文摘

SIs is a kind of phytoestrogens which are competitive with estrogens in organism. Although SI plays an important role in the regulation of reproduction, its role in testis development in the rooster is unknown. SIs (5 mg/kg) significantly increased the testis index and serum levels of reproductive hormones although SI had no significant effect on the body weight. SIs (5 mg/kg) significantly increased StAR mRNA content. However, there were no significant effects on p450scc and 3β-HSD mRNA level. These results suggest that SIs promote testicular growth by increasing reproductive hormone secretion, which is closely related to StAR expression, to positively regulate reproduction in young roosters.
