摘要: Abstract Hemicastration of males increases weight remaining testis when conducted before Sertoli cells cease to proliferate. The current studies re-examined responses hemicastration in one-quarter Meishan crossbred boars that differed for two alleles thyroid-binding globulin (TBG). In the first experiment, at 25 days age with either allele did not differ degree testicular development; however, 56 days, C had more advanced development than littermates A as evidenced by testes seminiferous tubules larger diameter ( P
