Document Summary
Is wasteful of food and land resources that could be used directly to feed people. For each of the feed components listed below, give a product of digestion, which can be absorbed. (1 pt) Cellulose in roughage = vfa or any of acetate, propionate, butyrateb. Oil in corn = fatty acids or could be: saturated fatty acids or glycerolc. Protein in soybean meal = amino acids: over a 7 day digestion trial, a steer ate 100 pounds of hay, which contained 10% crude protein. The steer excreted 200 pounds of feces, which contained 2% crude protein. 100 lbs x 0. 1 (ie, 10%) = 10 lbs of protein consumed; 200 lbs x 0. 02 (ie, 2%) = 4 lbs of protein excreted. So, by difference: 10 4 = 6 lbs of protein was apparently absorbed (digested) 6/10. = 60% apparent digestibility of protein in the hay.
