Comfortable beds play an important role in increasing the ruminant and milk production efficiency of dairy buffalo. In loose housing systems, cow lying comfort depends on both the bedding materials and bed base.
Buffaloes spent more lying time on sand beds at depth of 15 and 20 cm (S-15 and S-20) than on beds of 10 cm (S-10a) beds or in the feed alley in Exp1 ( < 0.01). No significant difference in the cow comfort index (CCI) was detected between S-10a and S-15; however, both showed higher CCI than that of the S-20 bed. In Exp2, buffaloes spent more time lying on the wood shavings at depth of 15 cm (WS-15) bed followed by the WS-20 and S-10b beds, respectively ( < 0.01), and CCI was greater in the WS-15 bed than in the S-10b and WS-20 beds ( < 0.05).
A depth of sand or wood shavings at 15 cm can meet the lying comfort requirements of dairy buffaloes when bedding materials are used above drainage beds.
舒适的牛床对提高奶水牛的反刍和产奶效率起着重要作用。在散栏饲养系统中，奶牛的躺卧舒适度取决于垫料和床基。
在实验1中，水牛在15厘米和20厘米厚的沙床（S-15和S-20）上的躺卧时间比在10厘米厚的沙床（S-10a）或饲料通道上的躺卧时间更长（P<0.01）。S-10a和S-15之间的奶牛舒适度指数（CCI）没有显著差异；然而，两者的CCI均高于S-20床。在实验2中，水牛在15厘米厚的木屑床（WS-15）上的躺卧时间更多，其次分别是WS-20和S-10b床（P<0.01），且WS-15床的CCI大于S-10b和WS-20床（P<0.05）。
当在排水床之上使用垫料时，15厘米厚的沙子或木屑可以满足奶水牛的躺卧舒适要求。
