中文摘要

The purpose of this experiment was to study whether environmental temperature could influence lactating sows’ behavior. 12 LY sows were randomly distributed into three temperature treatments: 14℃, 22℃, and 30℃. Behavioral observation was carried on for 24 hours at 0, 7, 14, 21, and 28 days after farrowing. Each sow was kept in a 1.8 m×2.3 m farrowing crate. Feed and water were provided ad lib. The results showed that sows had significantly higher (p<0.01) standing behavior in cold environment but significantly higher (p<0.01) lying behavior on side of body under high environment. Eating activity had significantly higher frequency when sows were kept in cool environment (P<0.05). The sows had significantly higher (P<0.01) drinking behavior when under higher temperature environment. There was less rooting behavior when sows were kept in high temperature environment. Sows had significantly higher dog sitting behavior when kept in an optimum environmental temperature. There was no significant difference on vacuum chewing among three treatments; however, the average figure was high for sows under optimum temperature. Bar and trough biting behavior occurred significantly more under low temperature.
