| 摘 要： | 饲养动物对畜舍的利用存在差别。该文选择泌乳中后期荷斯坦牛68头，观察其在不同时间段内对散栏饲养体系各场所的利用及对不同地面卧栏的选择性；以其中的12头分别作为试验组和对照组，观察其对散栏饲养体系各场所的利用时间。试验研究结果表明：泌乳中期和泌乳后期的奶牛，对散栏饲养体系各场所的利用时间差异极显著（P<0.01）；整个牛群在不同时间段对散栏饲养体系各场所的利用和对不同地面卧栏的选择性差异均显著（P<0.05），对沙土地面卧栏的选择多于橡胶地面卧栏。

| Abstract: | The utilization of barns for different type of fed animals is different.The utilization of different facilities and the selection to different cubicle beds in free-stall barn system in different time period were observed with 68 Holstein cows in middle and late lactation. The utilization time of different facilities in free stall barn system were observed with 12 cows in experiment and control group. The experiment results showed that the utilization time of different facilities for middle and later lactation cows were significantly different (P<0.01) in the free-stall barn system. The frequency of selecting different facilities and different cubicle beds were significantly different (P<0.05). The proportion of selecting the sandy bed was higher than that of the rubber bed in the resting cubicle,which the sandy bed should be popularized in this system in the future. |
