Effects of "Breed up" on non-seasonal spermatogenesis in ovine

Rams of Suffolk and Rambouillet influence were placed on a 60-d trial to determine the value of the trade product “Breed Up” in semen production through the summer months. Final collection was June 27 when ambient stress is generally at its highest point. Semen characteristics such as scrotal circumference, volume, concentration, and motility were used in the evaluation of the success of the product. While no significant values were recorded (P < .05), it was proven that the rams subject to the treatment group better maintained their ability to produce more fertile semen. Also, all rams within the treatment group showed an improvement in all four of the characteristics studied as opposed to those rams that were in the control group.
