| 摘 要： | 为确定补氮碱化处理秸秆的营养价值,用河北细毛羊作为试验动物开展了动物饲养试验.结果表明:(1)饲喂补氮碱化处理小麦秸能显著提高羊的增重、增重耗料比和秸秆采食量.尤其7%熟石灰 2%尿素处理小麦秸最好.(2)在酸性饲料调和的情况下,用补氮碱化处理小麦秸喂羊,日补饲精料274 g/只,日增重可达98.21 g/只,耗精料增重比为2.79.(3)酸性饲草饲料是进一步提高补氮碱化处理小麦秸饲喂效果的增效剂.

| Abstract: | To reveal the nutritive value of the wheat straw treated with alkali and supplied urea, the feeding experiment was done with.which Hebei fine-wool sheep which were fed with the wheat straw. The results showed: (1) When the sheep being fed with the straw, live weight gain, gain concentrate ratio and straw intake increased. The wheat straw treated with 7% Ca(OH)2+2% urea was best in nutitive value. (2) When the sheep being fed with the wheat straw, supplied with 274g concentrate and some acid feed, daily gain was 98.21g and gain concentrate ratio was 2.79. (3) Acid feed is one kind of materials increasing the feeding value of the wheat straw. |
