The OSU diet had a calculated E content of 5790 kcal/kg dry matter and a calculated ME content of 4410 kcal/kg dry matter. (The ME calculation employed: (1) the specific digestibility coefficients reported by Glem-Hansen and Joergensen (1978) for the proximate constituents of similar diet ingredients, and (2) the values of 4.0, 9.5, and 4.5 kcal ME/g of digested carbohydrate, fat and protein, respec- tively (Glem-Hansen, 1978). The calculated ME in this instance is 76.2 percent of the calculated E.)
