Dr. Juan Tricarico brought the history of yeast research to the audience at the Dairy Solutions Symposium. He is Research Manager for Ruminant Nutrition for Alltech. He says there is a lot of information about yeast and its mode of action. He hopes that participants in the symposium will leave with a better understanding of how yeast affects rumen function and improves the ruminal environment as a whole so that it can be used more effectively. This will give the dairy farmer a bigger bang for their buck when they invest in yeast products.
