Beef Nutrition

Wagner Cattle is a long time client of Caswell Nutrition. Dr. Caswell designs feeding program formulation for every phase of the animal's life, and develops an array of feeding options and solutions for very diverse and challenging situations. Dr. Caswell's clients range from other cow/calf operations, to backgrounders—grow yards—and feedlots from Illinois, Missouri and Kansas.
