Abstract:Cow abortion is a common issue in dairy cattle farming. If not actively prevented and treated promptly, it can lead to extended breeding cycles and reduced calving rates, thus causing significant economic losses to the livestock industry. This study analyses cases of cow abortion that occurred on a specific cattle farm between October 2022 and September 2023. The statistical results revealed that out of 29 reproductively capable cows, 29 calves were born, but unfortunately, 9 of the newborns died, resulting in an alarming abortion rate of nearly onethird. To identify the underlying causes of these abortions, this research conducted comprehensive investigations and tests on various factors, including environmental conditions, feed quality, and medication practices. The study revealed severe contamination of silage feed with mold and a significant excess of Aflatoxin B1. Considering these findings and the overall examination, the preliminary conclusion points to prolonged consumption of Aflatoxincontaminated feed as the fundamental cause of cow abortions. To mitigate the abortion rate, this study proposes a series of targeted preventive and control measures. These measures include monitoring animal health, regulating feed management, and conducting regular tests for mold toxins. The objective is to minimize the incidence of cow abortions and provide valuable assistance to fellow professionals and cattle breeders.
