receiving, calves, ddgs, dip
This experiment was designed to determine whether DDGS could be used as the primary source of supplemental crude protein in receiving calf diets. Diets included 45% oat hay and rolled corn. The control diet included 11.8% SBM as the source of supplemental crude protein. The DDGS was fed at 18.9% of diet replacing SBM. There was 1.3% SBM included in the DDGS diets. Diets were formulated for 13% CP and 48 Mcal/cwt NEG. The 47-d experiment began at arrival at the feedlot and involved 294 steer calves (604 lb). Calf gains (2.49 vs 2.54 lb/d) and F/G (5.76 vs 5.61) were similar for SBM and DDGS diets, respectively. The steers fed the DDGS consumed slightly less feed (14.34 vs 14.17). Overall morbidity rate was low (2.4%) with no apparent influence from diet. The use of DDGS as a primary source of supplemental CP in calf receiving diets appears to be acceptable in spite of a calculated deficiency in ruminally degradable crude protein.
