摘要

This study was?intended?to evaluate?in situ?rumen degradability characteristic of soybean curd residue?(SCR)?and peppermint compared to rice straw, which are used as a functional feed source?for?beef cattle for high quality beef production. Two steerswere?fitted with rumen and duodenum cannulae?and?in situ?degradable and nylon bagswere used?to assess digestion?of rice straw, SCR and peppermint?in three replicated experiments. The highly effective dry matter (DM) degradability of peppermint was attributable to the high rate of the?a?and?b?fractions. Dry matter disappearance rate of SCR after 48 h was higher (p < 0.05) than that of peppermint. Based on DMdisappearance, SCR showed the highest?digestibility?(p < 0.05). Crude protein disappearance (%) was higher for SCR and peppermint than rice straw (p < 0.05), and neutral detergent?fibre?disappearance (%) was higher for SCR (p < 0.05).Soybean curd residue and peppermint have great nutritive values as feed sources for ruminants, and using SCR and peppermint would have possibilities for efficient and functional livestock production.
