| 摘 要： | 用全收粪法对当地农户收贮的苜蓿干草进行了采食量及表观消化率的测定。结果表明，小尾寒羊对苜蓿干草的采食量为936．4g／只·d-1，采食率为72．61％，（51．735％～88．13％）。表观消化率分别为：干物质43．53％；粗蛋白48．30％；粗脂肪14．89％;粗纤维40．30％；粗灰分19．51％；无氮浸出物46．92％。

| Abstract: | The intake and apparent digestibility of alfalfa hay on Xiaoweihan sheep were determined in Qingyang with total conection method. The results indicated that the intake was 936.4 g/head.d, and the intake rate was 72.61% (from 51.73 % to 88.13 %). The apparent digestibility was 43.53 % for dry matter, 48.30 % for crude protein, 14.89 % for crude fat,40.30 % for crude fibre, 19.51 % for crude ash and 46.92 % for nitrogen-free extract, respectively. |
