Researchers have known for many years that it takes more feed to produce live weight gain in ruminants than in nonruminants. It is also known that ruminants derive their major energy supply from volatile fatty acids, rather than from glucose as monogastrics do.

The study of protein and energy in the ruminant does merit considerable attention, especially their relationship at the tissue level. The problem arises however, in trying to avoid the rumen fermentation the normally occurs.

Three experiments were conducted to determine the effect of glucose and casein on ration digestibility and nitrogen utilization by steers. The first experiment involved a series of three metabolism trials with 6 Hereford steers. The second experiment involved 4 fistulated Hereford steers in a 4 x 4 Latin Square design. There was a series of four metabolism trials with 4 treatments. In experiment 3, 4 intact Hereford steers were used in another 4 x 4 Latin Square design utilizing 4 different rations and 4 metabolism trials.
