Abstract

Third cut wilted grass was ensiled and fed to 4 rumen cannulated Texel wethers at 883 or 1248 g DM daily in 6 equal portions with 4-h intervals. Passage of the reticulo-ruminal particulate phase to the lower gut was estimated with chromium-mordanted neutral-detergent fibre (CrNDF) and tritium-labelled hay as markers, the latter subject to both passage and reticulo-ruminal degradation. Fractional passage rates (kp) were deduced from faecal marker excretion curves. For CrNDF and tritium, kp averaged 2.44 (s.e.m. 0.19) and 3.38 (s.e.m. 0.20) %/h, respectively; difference was significant. (Abstract retrieved from CAB Abstracts by CABI’s permission)
