Pedro Fontes, Ph.D. – Assistant Professor and Extension Specialist – We now know that a variety of factors such as nutrition, semen quality, AI technician, and vaccinations (to name a few) can influence the success of an AI program. In this article, Dr. Pedro Fontes discusses how long-term commitment to estrus synchronization and AI influence…

Pedro Fontes, Ph.D., Assistant Professor and Beef Extension Specialist – Cattle producers commonly evaluate reproductive performance by determining how many cows became pregnant during the breeding season. Although pregnancy rates are important, when females become pregnant within the breeding season is also a key component of cow-calf profitability. In this short article, Dr. Fontes discusses…
