摘要： 选用4头装有永久性瘤胃瘘管的初产奶牛采用4×4拉丁方设计，研究不添加油脂（CK）、添加4％豆油（LOC1）、4％胡麻油（LOC2）以及2％豆油+2％胡麻油（LOC3）对DM、OM、NDF、ADF瘤胃表观消化率及全肠道消化率的影响。结果表明：在60%高粗料日粮基础上添加4%豆油、亚麻油或二者的混合物，对奶牛干物质采食量没有影响。与对照组相比,添加油组DM、OM、NDF、ADF的瘤胃表观消化率和全肠道消化率都有降低的趋势，但差异不显著（P＞0.05），3个添加油组之间差异也不显著（P＞0.05）。

Abstract: Four primiparous Holstein cows with cannulas in the rumen and proximal duodenum were randomly assigned to four diets with a 4×4 latin square experiment. Cows in four treatment were fed high forage（60%DM） diets without oil supplement（CK）, 4% soybean oil（LOC1）, 4% linseed oil（LOC2） or mix of 2% soybean oil and 2% linseed oil（LOC3） on dry matter basis. The objective was to examine the effects of supplemental fat on intake, apparent ruminal digestibility, and total tract digestibility of DM,OM,NDF and ADF in dairy cows. The results indicated that intake, apparent ruminal digestibility, and total tract digestibility of DM,OM,NDF,ADF were not affected by the oil supplementation(P＞0.05）,however the fat supplement tended to reduce the digestibility of DM,OM,NDF,ADF on rumen and total tract.

Key words: dairy cow; linseed oil; soybean oil; digestibility
