摘　　要：为了探讨自渗牛床不同表层垫料(河沙和甘蔗渣)对西门塔尔母牛体表清洁度的影响,试验选取体况良好、年龄及胎次接近的西门塔尔成年母牛30头,随机分成2组,15头/组,分别饲养在铺撒厚度为15 cm的河沙与甘蔗渣表层垫料的自渗牛床上,按照4分制对西门塔尔成年母牛的乳房、左侧上腿部、右侧上腿部、左侧下腿部、右侧下腿部、腹部、尾部7个体表部位进行连续10 d的清洁度评分。结果表明:牛群在两类垫料上的体表清洁度差异不显著(P>0.05),且均无最肮脏的4分;乳房清洁度评分最低,最清洁的1分所占比例为98%,2分所占比例为2%,3分所占比例为0。说明自渗牛床配合厚度为15 cm的甘蔗渣或河沙作为表层垫料均能维护牛群良好的体表清洁度。In order to explore the effects of river sand and bagasse above the self-draining bed on the body surface hygiene scores of Simmental cows, thirty health Simmental adult cows with similar age and birth order were selected and randomly divided into two groups, with 15 in each group. The cows were feeding in the river sand and bagasse above the self-draining bed covered with 15 cm thick, respectively. On a 4-point scale, 7 individual table parts of simmental adult cows were rated for cleanliness for 10 consecutive days, including including udder, left upper rear leg, right upper right leg, left lower rear limb, right lower rear limb, belly, and tail. The results showed that there was no significant differences in body surface hygiene scores of cows between the river sand and bagasse(P>0.05), and neither of them reached the dirtiest 4 score. Breast cleanliness scores were lowest. The proportions of 1, 2, and 3 scores were 98%, 2%, and 0 for udder, respectively. The results indicated that the self-draining bed with 15 cm thick bagasse or river sand as the surface bedding could maintain good body surface cleanliness of Simmental cows.
