After the Abstract: Pregnancy Loss in Crossbred Beef Cows
On this episode of After the Abstract on Bovine Science with BCI reviews a recent study on pregnancy loss in crossbred beef cows, focusing on factors that influence whether pregnancies are maintained after conception. The vets highlight that estrus expression at the time of artificial insemination, cow body weight, and season all play significant roles, with lighter cows, those not showing estrus, and those bred in the dry season experiencing higher loss rates. They also emphasize that changes in body condition after breeding, especially losing condition, are strongly associated with increased pregnancy loss. Overall, the discussion suggests that nutrition and reproductive physiology are key drivers of pregnancy retention, even more than factors present at the time of breeding.
