【摘要】 通过在广东省湛江市的夏季人工混播草地自由放牧黑山羊,研究了大花牵牛、柳叶箬、白茅等5种植物适口性,结果表明:5种植物的适口性表现各不同,以大花牵牛的适口性表现最好;影响植物适口性指数的因子为植物含水量和无机盐含量,其中又以植物含水量影响最大,而植物的单宁含量对适口性表现没有直接的影响。更多还原

【Abstract】 Through the free-grazing black goats in mixed grassland in Zhanjiang City of Guangdong Province in summer, the palatability of Ipomoea nil,Isachne globosa&Imperata cylindrica were studied. Result shows that five plant species have different palatability,the palatability of black goats is the optimal. The factors affecting the palatability index of plants are water content of plant & inorganic salt content, among which the plant moisture content is the most affected, while the tannin content of plant has no direct impact on palatability.更多还原
