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 (P < 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 (P < 0.01), and CCI was greater in the WS-15 bed than in the S-10b and WS-20 beds (P < 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.

温带气候下覆盖沙子和刨花的排水床对奶牛舒适行为的影响

舒适的床对提高奶牛的反刍动物和产奶效率起着重要作用。在松散的畜舍系统中，奶牛躺卧的舒适度取决于垫料材料和床底。在 Exp1 中，水牛在 15 和 20 厘米（S-15 和 S-20）深度的沙床（S-15 和 S-20）上的躺卧时间比在 10 厘米（S-10a）床或饲料小巷中的时间长（P < 0.01）。S-10a 和 S-15 之间的奶牛舒适指数 (CCI) 没有显着差异；然而，两者都显示出比 S-20 床更高的 CCI。在 Exp2 中，水牛在 15 cm (WS-15) 床深的刨花床上花费的时间更多，其次是 WS-20 和 S-10b 床（P < 0.01），并且 CCI 在 WS- 15 床位高于 S-10b 和 WS-20 床位 (P < 0.05)。
