This study aimed to evaluate among the seminal characteristics, sperm concentration of Santa Inessheep, aged 22-36 months treated with recombinant bovine somatotropin (rbST). Divided into groups randomly:GI (2mL / 0.9% NaCl), G-II (100mg / rbST) and G-III (125mg / rbST), receiving treatments subcutaneouslyevery 14 days (D0,14,28, 42,56,70). They were measured scrototesticular biometrics. The ejaculates werecollected by artificial vagina, with dummy sheep, and analyzed for volume, vortex, motility, vigor, morphologyand sperm concentration. There was no significant difference (P > 0.05) in PE (30,1cm) and in almost all semenparameters. However, on sperm concentration (sperm / mL) in G-III, there was an increase (787.69 ± 480.72)compared to groups. It was concluded that the dose of 125mg / rbST increases the sperm concentration of ovineSanta Ines.(AU)
