    (2024-08) Andaluz De Mora, Sandra Daniela; Rosero Peñaherrera, Marco Antonio
    The objective of this project was to determine the influence of drug-induced stress and scrotal temperature on semen quality in sheep. This study was conducted at the “San Pedro” farm, San Miguel canton, Bolívar province. Three treatments were used for the experiment: T1 treatment with scrotal heat patch, T2 with intramuscular dexamethasone and T3 control treatment. Nine crossbred male sheep and two females were used as dummies for mating. Two semen collections were carried out per week and different analyses were obtained from pools composed of three ejaculates from different sheep, for each treatment, with a Complete Random Design. The results of the means of each treatment, of the different variables were evaluated through Kruskal Wallis tests and significance through the Tukey test at 5% in the Infostat software, considering statistically significant differences when P < 0.05. The variables analyzed were both macroscopic and microscopic, such as: volume, color, mass motility, individual motility, concentration and morphology, in fresh semen. Concluding that the influence of induced stress and scrotal temperature negatively affects semen quality in sheep.
