Estudio del estatus ovárico de las hembras bovinas faenadas en el camal Cafrilosa de la ciudad de Loja

Reproductive health in cattle is essential for the sustainability and profitability of the cattle industry. Reproductive problems in cattle have different causes, which affect the reproductive efficiency and productivity of cattle, generating significant economic losses for owners. In Ecuador, the lack of studies in the province of Loja has left a crucial gap in the understanding of ovarian pathologies in bovine females in the herds of the canton and the province. For this reason, this study aimed to characterize the ovarian status of cattle slaughtered in the Cafrilosa slaughterhouse in the city of Loja. Data were collected from 357 animals to provide accurate information on the prevalence and severity of these pathologies. Several pathologies were identified, such as follicular cysts 0.28% in the right ovary and luteal cysts 0.6% in the left ovary, as well as ovarian atresia 0.56% in the right ovary, 1.7% in the left ovary, which can affect reproduction and milk production. Small follicles, old corpora lutea and pre-ovulatory follicles were common in both ovaries, indicating different phases of the estrous cycle. Ovaries with pathologies were observed to have atypical measurements, suggesting a possible relationship between size and reproductive health. Regarding factors such as age, breed, origin and body condition, no significant differences were found in relation to ovarian pathologies. This suggests that these pathologies are not strongly influenced by these factors in the sample studied. This study not only benefits producers by improving animal health and reducing treatment costs, but also contributes to the knowledge of the causes and consequences of ovarian pathologies, allowing the implementation of preventive measures and adequate management in the province of Loja.
