摘　　要：采用一种生物化学及生物活性物复合制剂 ,无需外加微生物 ,直接发酵搓揉处理的秸秆 ,靠天然有益菌的快速的增殖 ,并抑制杂菌的生长 ,降解秸秆粗纤维 ,增加菌体蛋白质 ,提高秸秆的生物学价值和有效养分的利用。用该生化培养剂处理稻草 ,蛋白质含量可提高 2 6 0～ 3 39个百分点 ,可降低粗纤维 1 0 4 2～ 1 6 5 9个百分点。以秸秆生化培养剂发酵稻草 70 86 %、发酵脱毒棉籽饼 1 2 2 7%、大豆粕 1 5 34 %、食盐 1 5 %组成的饲粮 ,饲喂舍饲杂交肥育肉牛 ,日增重达到 1 5 0 0～ 1 833g ,增重料比达 3 5 6～ 4 35。The straw is fermented by a complex preparation with biochemical and biological activity without adding artificial rearing strains so as to increase bacterial protein by breeding useful bacterium And also the preparation has the effects to inhibit useless bacterium growing and lower crude fiber So the effective nutrient and biological value of straw can be increased by 2 60～3 39 points percent, but crude fiber level can be reduced by 10 42～16 56 points percent The daily weight gain of yard finishing beef fed on diet formulated with fermented straw 70 86%, fermented and detoxicated cottonseed cake 12 27%, soybean cake 15 34% and 1 5% can reach 1 500～1 833 g and the feed convertion rate can reach 3 56～4 35
