Pregnancy is the key to profitability, ensuring your herd remains in the most profitable phase of production. However, these early embryos are delicate and often are not carried out through the entire 283 days of gestation. This month we talk with Dr. Stephen LaBlanc, from the University of Guelph about quantifying the frequency of early pregnancy loss in healthy animal and his team’s quest to determine the impact of a failed transition on the cow’s ability to carry the pregnancy to term.
Through management, a producer can prevent the spiral of negative events that result in increased odds of pregnancy loss. The research team determined day 19 pregnancy and tracked the success, or failure, through day 63. Listen in to hear what different parameters they found to have an increased probability of early pregnancy loss.
These findings were published in the Journal of Dairy Science article titled, “The associations of inflammatory and reproductive tract disorders postpartum and early pregnancy loss in dairy cows” This open access article, is available for download to view while you listen in!
