摘要: BACKGROUND Hop cones contain several antimicrobial substances. The aim of the study was to determine effects two hop varieties, Aurora and Dana, on substrate (diet for a dairy cow, producing 30 kg milk daily) in vitro dry matter (DM) crude protein (CP) degradability digestibility. RESULTS In trial freshly ground hops were added buffered rumen fluid concentrations simulating cow's daily intake 50, 100 200 g hops. Increasing concentration decreased (P < 0.05) both average DM degradabilities from 725 592, 553 481 kg−1, respectively, CP 752 566, 561 478 respectively. reduction is counterbalanced by (invariable) digestibility. difference between digestibility represents an estimate amount ‘bypass’ which increased with increasing 172 454 kg−1. CONCLUSIONS Decreased could lower amounts required high-producing ruminant animals. However, this supposition needs validation vivo trials. © 2013 Society Chemical Industry
