Past Project 2015-2019: Effect of Selenium-Enriched Hay fed to cows during the dry period on immunity of peripartum cows and calves

The project aims to determine the effect of feeding a specific amount of Se-enriched Alfalfa to dairy heifers during 40 days pre-partum and for 14 days post-partum and evaluate the effect on the immune system, including transcriptome of liver and macrophages in milk, of the cows and of their calves.

The project is led by Shana Jaff and Matteo Mezzetti and is done in collaboration with Dr. Charles Estill (OSU), Dr. Gerd Bobe (OSU), and Dr. Trevisi Erminio (Universita Cattolica del Sacro Cuore, Italy)
