| 中文摘要 | wheat straw was treated with microwave for 4 min and 8 min at a power of 750 w and frequency of 2,450 mhz. chemical compositions of untreated, 4 min treated and 8 min treated straws were analyzed and in sacco degradabilities of all these straws in yak rumens were measured. microwave treatment didn't significantly (p > 0.05) affect the chemical composition of the straw. in sacco dry matter (dm) degradability of the straw after 18 h incubation in rumen was significantly (p < 0.01) improved by microwave treatment. in sacco crude protein (cp) degradability of the straw was not (p > 0.05) affected by microwave treatment. in sacco organic matter (om) degradability of the straw was increased (p < 0.01) by around 20% for both the 4 min and 8 min microwave treatment, that of acid detergent fibre (adf) was increased (p < 0.01) by 61.6% and 62.8%, and that of ash free adf was enhanced by 72.1% and 69.6% for the 4 min and 8 min microwave treatment respectively. no significant difference was observed between the 4 min and 8 min microwave treatment on the degradability of dm, om, cp, adf and ash-free adf of the straw. |
