摘要

本研究共6组6只妊娠母羊，采用转换设计。在第一阶段，第1、2和3组可以接触到水乳头，第4、5和6组可以接触到水碗，第二阶段反之亦然。在第三阶段，所有六组都可以使用两种饮水机。母羊乳头采水量(3.27±0.29 l/只母羊/天)显著高于碗采水量(2.04±0.22 l/只母羊/天)(F = 78.28, P < 0.001)。乳头的用水量占用水量的36%，而碗的用水量可以忽略不计。当同时提供两种饮水器时，母羊的饮水量倾向于从奶嘴中获得更高的饮水量(t = 0.69, P < 0.10)，母羊似乎对奶嘴或碗没有特定的偏好。

The preference for water nipples vs. water bowls in pregnant ewes

ABSTRACT This study included 6 groups of 6 pregnant ewes with a change-over design. In period 1 group 1, 2 and 3 had access to the water nipples and group 4, 5 and 6 had access to water bowls and vice versa in period 2. In period 3 all six groups had access to both types of water dispensers. The ewes’ water intake was significantly higher when drinking only from water nipples (3.27 ± 0.29 l/ewe and day) than only from water bowls (2.04 ± 0.22 l/ewe and day) (F = 78.28, P < 0.001). The water wastage for nipples was 36% of water usage and negligible for bowls. When offered both dispensers the ewes' water intake tended to be higher from water nipples (t = 0.69, P < 0.10), and there seemed to be no specific preference for water nipples or bowls in ewes.
