This study aims to assess the effects of thermal stress on semen parameters of Alpine bucks. The study will be conducted over three months - January (winter), April (spring), and June (summer) - to determine the impacts of cold and heat stress. Blood and semen parameters like red blood cell count, white blood cell count, packed cell volume, hemoglobin levels, ejaculate color, consistency, volume, sperm concentration, motility, viability, and morphology will be evaluated to understand how thermal stress influences the physiological and biochemical traits of buck semen.
