Abstract
Digestion trials were conducted to study the effect of dry heating soybean protein to reduce its solubility on nutrient utilization pre and post-abomasally. The soybean meal was heated at 149 C for 4 hr. in a forced-air oven which reduced protein solubility from 72% to 35%. Heating the soybean meal significantly (P<.05) increased the concentration of dry matter and nonprotein nitrogen in the abomasum. Protein nitrogen on a dry matter basis was not affected. Nitrogen, cellulose and dry matter digestibilities were not affected by heating the soybean meal administered posterior to the abomasum.Keywords
