Digestibility, Protein Metabolism and Ruminal Degradation of Beagle 82 Triticale and Kline Barley Fed in Corn-Based Cattle Diets^1,2,

University of Georgia, Tifton 31793-0748

Abstract

Trials were conducted to evaluate Beagle 82 triticale and Kline barley in cattle diets. Grain portions of dietary treatments in metabolism and feedlot trials contained 70% corn and 6% soybean meal (C), 38% corn and 38% triticale (CT) and 38% corn and 38% barley (CB). In a metabolism trial (replicated 3 x 3 latin square; six steers), apparent digestibility of DM, OM, crude fiber and CP were similar for C, CT and CB diets, but ether extract digestibility was lower (P < .05) for CT and CB diets. Retained N was similar (P > .14) for C, CT and CB diets. In a feedlot trial (18 individually fed heifers), ADG and feed/gain were similar for C, CT and CB diets. Dietary amino acid profiles were very similar for C, CT and CB diets, but plasma isoleucine, leucine, methionine, threonine, valine, total essential and total amino acids were higher (P < .05) for both CT and CB diets vs C on d 55. In an in situ trial, solvent-extracted cottonseed meal (CSM), corn, triticale and barley were suspended in the rumen in dacron bags for periods of 1 h to 16 h. Triticale DM disappeared slightly faster than DM in other treatments, total N in triticale disappeared faster (P < .05) than that in corn and barley (3.54 vs 1.13 and 1.48%/h, respectively), and triticale feed N disappeared faster (P < .01) than corn N (3.49 vs .59%/h). Beagle 82 triticale and Kline barley may be substituted for corn and supplemental protein without jeopardizing performance of growing beef cattle.
