摘要
作者测定了绵羊对盛花期红豆草青干草的采食率及各营养物质的消化率,其结果干物质的采食率为78.38％,消化率为60.45％。而有机物、粗蛋白、粗脂肪、粗纤维、粗灰分、无氮浸出物、钙和磷的消化率依次为61.77±2.19、64.49±3.00、57.89±2.25、51.26±3.97、43.05±4.29、69.02±2.07、16.76±5.98和23.58±9.44。试验期间绵羊日增重为169.1克,说明盛花期红豆草品质优良,饲用价值高。
This paper reported the intake rates and digestibility of sainfoin (Onobrychis spp) at full flower stage by pen feeding fine wool sheep. The results showed that 78.38％ of sainfoin in the diet was taken by the sheep, the digestibiliy of dry matter was 60.45％. Digestibility of organic substance, crude protein, crude fat, crude fiber, crude ash, nitrogen-free extract, calcium and phosphorus was 61.77±2.19, 64.49±3.00, 57.89±2.25, 51.26±3.97, 43.05±4.29, 69.02±2.07, 16.76±5.98 and 23.58±9.44, respectively. During the experimental period sheep live weight gain was 169.1g/day. It suggested that sainfoin in full flower stage has a hig feeding value.
