Protein supplementation and comparative feeding value of alkaline hydrogen peroxide-treated wheat straw-containing diets fed to cattle and lambs

Experiments were conducted to study protein supplementation of alkaline hydrogen peroxide-treated wheat straw (AHPWS)-based diets and to compare the feeding value of AHPWS to corn silage (CS). A lamb metabolism experiment was conducted to determine the dietary CP level needed to maximize nitrogen (N) retention and fiber digestibility. Soybean meal (SBM) replaced corn to increase levels of CP (range = 6 to 16% CP). Maximal N retention (% of N intake) and NDF digestibility were obtained with 12% CP. Similar treatments (8.5, 11, 13.5, 16 and 18.5% CP) were used with cannulated lambs to characterize the duodenal amino acids (AA) supply. Total, bacterial and nonbacterial N and AA flow to the duodenum increased with increasing CP level. The profile of AA entering the small intestine was not substantially altered.
