摘要

In two cattle finishing experiments pressed brewers' ensiled grains and brewers' dried grains, respectively, were compared with conventional protein concentrates. In both experiments maize silage was fed ad libitum. In trial 1, 24 Simmental bulls were fed on pressed brewers' ensiled grains (BTS) or soyabean meal (SOJA) as a protein concentrate beginning at an initial liveweight of 350 kg. 15 bulls were used in trial 2 using a 3 X 3 Latin square design to compare protein sources BTS or brewers' dried grains (BTT) and a conventional protein concentrate (PKF) consisting of 25% of each of soyabean meal, rapeseed meal, faba beans and peas. Each period consisted of a 7-day adjustment period followed by 49 days of evaluation. In both experiments feed andenergy intake were lower in the BTS group. Differences were significant only in experiment 2 because of high standard deviations in experiment 1. Energy intake in experiment 2 was 102.9 (PKF), 102.6 (BTT) and 93.5 (BTS) MJ ME/day. In both experiments daily weight gains were lower in the BTS group but differences were not significant. In experiment 1 daily weight gains were 1192 g (SOJA) and 1054 g (BTS). In experiment 2 daily gains decreased from 1355 (PKF) to 1274 (BTT) and 1103 g (BTS). Results werecomparable for feed conversion efficiency. In experiment 1, dressing percentages were significantly lower for group BTS.
