多花黑麦草在生长兔上的营养价值评定

为评定多花黑麦草在生长兔上的营养价值,研究以福建黄兔为对象,对2个多花黑麦草品种采用全粪收集法进行消化试验。结果表明：福建黄兔生长兔对多花黑麦草‘美克斯’和‘海里克斯’干物质（DM）、粗蛋白质（CP）、粗纤维（CF）、中性洗涤纤维（NDF）、酸性洗涤纤维（ADF）、粗脂肪（EE）、粗灰分（ash）、钙（Ca）、磷（P）和无氮浸出物（NFE）的表观消化率分别为：52.67%、82.68%、21.70%、26.58%、28.59%、68.37%、57.69%、71.64%、70.82%、64.38%和50.45%、79.53%、24.69%、30.45%、32.69%、69.84%、59.38%、70.48%、69.31%、69.30%。其中生长兔对多花黑麦草DM、CP、EE、Ca和P的表观消化率较高,对CF的表观消化率较低。

Assessment on Apparent Digestibility of Main Nutrient in Italian Ryegrass for Growing Rabbits

The digestibility of main nutrient in 2 varieties of Italian Ryegrass for growing Fujian yellow rabbits was assessed by endogenous indicator method. The results show that: the digestibility of ryegrass "Maximus" and "Hercules" dry matter (DM), crude protein (CP), crude fiber (CF), neutral detergent fiber (NDF), acid detergent fiber (ADF), crude fat (EE), crude ash (ash), calcium (Ca), phosphorus (P) and nitrogen free extract (NFE) digestion rates was: 52.67%, 82.68%, 21.70%, 26.58%, 28.59%, 68.37%, 57.69%, 71.64%, 70.82%, 64.38% and 50.45%, 79.53%, 24.69%, 30.45%, 32.69%, 69.84%, 59.38%, 70.48%, 69.31%, 69.30%, respectively. The apparent digestibility of Italian ryegrass DM, CP, EE, Ca and P was high, and the apparent digestibility of CF was low.
