| 摘 要： | 研究选用4头装有永久性瘤胃瘘管的肉牛,利用尼龙袋法比较研究大豆粕、膨化全脂大豆与焙烤大豆对瘤胃干物质、蛋白质降解率及瘤胃动态降解参数的影响。结果表明:与大豆粕相比,膨化全脂大豆及焙烤大豆的干物质及蛋白质的快速降解组分(a)比例显著下降(P<0.0001),慢速降解组分(b)比例显著提高(P<0.0001)。膨化能够显著降低大豆蛋白质的瘤胃降解率,进而提高蛋白质的过瘤胃比例。焙烤大豆的瘤胃干物质、蛋白质降解率显著低于大豆粕但高于膨化全脂大豆。 |

| Abstract: | This experiment was designed by in situ technique to study cattle rumen degradation regularity of DM and protein of soybeans treated in different ways.Four Chinese cattle fitted with permanent cannules at the rumen were used in the single factor experiment.Results showed that the rapid degradation rate of DM and protein of extruded full-fat soybean and roasting soybeans were significantly decreased compared with soybean meal(P < 0.0001).Extruding can increase the rate of pass the rumen of soybean protein.Roasting soybeans can supply more potential undegradable protein compared with soybean meal. |
| Keywords: | processed soybeans degradation the of rumen kinetics paraments cattle |
