作者用绵羊对盛花期红豆草青干草氮磷和钙的代谢沉积率进行了测定,其结果氮为16.26％,磷为96.42％,钙为92.94％。在试验期间,绵羊平均日增重为169.1±54.7克,说明用盛花期刈割的红豆草调制的青干草具有优良的饲用价值。
The authors used sheep to determine the metabolic deposition rate of nitrogen and phosphorus and calcium in the sapling of Azolla at full bloom, with the results being 16.26% for nitrogen, 96.42% for phosphorus and 92.94% for calcium. During the experiment, the average daily gain of sheep was 169.1 ± 54.7g, which indicated that the green hay prepared by flowering-seasoned sainfoin grass had excellent feed value.
