Alternate Day Protein Supplementation Of Corn Stalk Based Diets With High And Low Ruminal Escape Protein Sources, R. M. Collins, R. H. Pritchard
South Dakota Beef Report, 1991
Twenty-four crossbred wethers (88 ± .44 Ib) were utilized to determine optimal level of dietary CP when corn gluten meal (CGM) and soybean meal (SBM) based supplements were fed alternate days. Diets were arranged in a 2 x 3 factorial design with SBM and CGM fed at 8, 9 or 10% dietary CP. Supplements were top dressed on ground corn stalks at a rate of two times the daily required amount (19.78% DM basis). The collection term consisted of an 8-day total feces and urine collection. DM1 and DDMl were improved (P<.01) when CGM was fed and as dietary CP was increased by either supplement. Dry matter digestibility (DMD) decreased (P<.05) as dietary CP level increased. Neutral detergent fiber digestibility (NDFD) did not differ (P>.05) for protein source or dietary CP level. …
