小麦秸与非常规饲料组合效应的研究
Combination Effects on Wheat Straw and Non-Conventional Feeds
摘要
Abstract
This experiment was conducted to investigate the combination effects of wheat straw ( WS ) and non-conventional feeds. Combinations of WS with spouting corn bran ( SCB ) , soybean hulls ( SH ) , orange peel ( OP) and apple pomace ( AP) were mixed in the proportion of 0∶100, 25∶75, 50∶50, 75∶25 and 100∶0, respectively, and rumen fermentation in vitro was adopted to evaluate combination effects by analysis of total volatile fatty acids ( TVFA) concentration, dry matter degradation rate ( DMD) , neutral detergent fiber degra-dation rate ( NDFD) and acid detergent fiber degradation rate ( ADFD) after 48 h. The results showed as fol-lows:1) in the combinations of WS with SCB, SH, OP and AP, when the proportion of WS was 25%, the TVFA concentration was higher than that of the WS proportions of 50%, 75% and 100%. 2) With the increas-ing of the proportion of WS, the DMD of combinations of WS with SCB, SH, OP and AP gradually de-creased; the DMD of combinations of WS with SCB and SH had significant difference in each proportion ( P<0.05). 3) With the increasing of the proportion of WS, the NDFD and ADFD of combinations of WS with SCB and SH gradually decreased, and had significant difference in each proportion ( P<0.05) . In the combina-tion of WS with OP, the NDFD and ADFD were the highest when the proportion of WS was 50%. 4) In the combinations of WS with OP and AP, when the proportion of WS was 50%, the combination effect values of NDFD and ADFD were the highest, which was significantly higher than the other proportions ( P<0.05); in the combination of WS with SCB, when the proportion of WS was 75%, the combination effect values of ND-FD and ADFD were the highest, which were significantly higher than the other proportions (P<0.05). It is concluded that the combinations of WS with SH and SCB in proportion of 75∶25, and the combinationsof WS with AP and OP in proportion of 50∶50 have the best combination e effects in this experiment.关键词
