ABSTRACT: This study evaluated the effect of climate change on andrological parameters of beef bulls raised under tropical, subtropical, and temperate conditions. Bull ejaculates were collected to evaluate seminal quality parameters, sperm membrane integrity, and redox status (SOD; GPx; GSH; GRx; CARB; DCF; and SOD/GPx ratio). Bulls located in the temperate region showed a higher sperm motility rate and percentage of viable sperm (P <0.05). When evaluating regions independently, we observed a lower GPx activity from animals in the tropical region (P <0.05). In contrast, we found that SOD and GRx activities, GSH content, and CARB oxidative levels were higher in the tropical region, while oxidation values of DCF were lower (P <0.05). Braford bulls showed higher CARB and DCF levels (1.23 ±0.61 nmol/mg and 1453.60 ±828.63 nmol/mg, respectively) compared to Hereford bulls (1.00 ±0.43 nmol/mg and 1138.70 ±423.24 nmol/mg, respectively) in the temperate region. However, Nellore bulls showed higher DCF levels (650.50 ±401.53 nmol/mg) than Braford bulls (409.40 ±286.97 nmol/ mg). In addition, the SOD/GPx ratio was lower in Braford (12.44 ±7.64 U/mg) compared to Nellore bulls in tropical conditions (87.25 ±2.83 U/mg). A positive correlation was found in temperate conditions between DCF levels, SOD, and GRx activities (0.51, 0.58; P <0.01, respectively), as well as in subtropical conditions between DCF levels and GRx activity (0.53; P <0.01). A negative correlation between the temperature-humidity index and CARB content was found in subtropical and tropical regions (?0.44; P <0.01). We concluded that Braford breeds showed lower seminal motility, DCF contents and SOD/GPx ratios compared to Nellore bulls in tropical climate conditions. Finally, in temperate environmental conditions, Braford bulls also showed lower seminal motility but higher levels of CARB and DCF contents compared to Hereford bulls. Therefore, the existence of climatic differences between the temperate and tropical regions evaluated affected Braford bulls? seminal motility and seminal redox homeostasis.
