Abstract

High cortisol levels resulting from lameness-associated pain decrease testosterone release and disrupt normal spermatogenesis in breeding bulls. As a result, lameness might negatively affect semen quality and lead to increased sperm defects. The objective of this study was to investigate the effect of lameness on cortisol and testosterone concentrations and semen quality of breeding beef bulls presented to a veterinary teaching hospital.
