Feed For Thought: Protein Part 2, "What are the signs, symptoms and treatment of a surplus of protein in the diet?"
By Suzie Middlebrook, BSc. | Cavalor Nutrition Specialist
As with many other things in the field of nutrition, there is such thing as too much protein in a horse's diet. In ration calculations and feed analysis, we refer to protein as crude protein (CP), which is essentially any and all protein in the diet without regard for the make-up or digestibility of the protein. The crude protein requirement of an average-sized horse in medium work is around 700g, which is more than met by 15 pounds, or 3 large flakes, of high quality grass hay with a crude protein level of 8.5% coupled with 4.5 pounds of performance horse grain, such as Cavalor® Perfomix (11% CP) (NRC, 2007). If a horse was fed instead a diet of 15 pounds of alfalfa (17.8% CP) and 1 pound of a high protein ration balancer (30% CP), that horse would be ingesting nearly double their daily crude protein requirement.
