Supplementary Effect of Corn Gluten Meal with Soybean Oil Meal ,

CHRISTIANSEN et al. (1940) showed that in a ration containing no animal protein, 11 percent of soybean oil meal plus 5 percent of corn gluten meal supported practically the same growth as did 16 percent of soybean oil meal. The rations contained approximately 18 percent of protein. Growth was better, however, when an animal protein supplement was included, probably because of the essential vitamins in the animal protein supplements. Van Landingham, Clark, and Schneider (1942) presented data on the percentage of protein utilization of several protein supplements. The proteins of soybean oil meal and corn gluten meal were utilized 76.0 percent and 28.7 percent, respectively. One-half soybean and one-half corn gluten meal had a calculated protein utilization of 52.4 but an actual protein utilization of 68.3 which indicated a supplementary value of 15.9 percent. Hammond (1944) published experimental results indicating that as much as 15 percent of corn gluten meal . . .
