In an ideal world, each time a cow was inseminated (intentionally inseminated that is, this is an “ideal” world) it would result in a live and healthy calf. Unfortunately, even though fertilization rate is about 95 – 98%, by day 28 after mating, only 70 % are still pregnant and there are further losses before calving. While the significance of this loss is easy to see, research to reduce this loss is still hampered by the lack of a reliable early pregnancy test. Nevertheless, we can improve our understanding of factors that are known to contribute to embryonic loss and seek to minimize the impacts.
