中文摘要

The purpose of the experiment is to compare the behaviour, stress and welfare implications of 3 different housing systems for sows. A total of 64 first litter LY Landrace ♀× Yorkshire ♂ sows used in the present experiment. There were 16 sows in stalls, 16 sows in groups (4 in each group), and 32 sows in electronic sow feeding (ESF) during gestation. There were four treatments during lactation stage. They were (1) 16 sows in stall moved to farrowing crate; (2) 16 sows in group pen moved to farrowing crate; (3) 16 sows in ESF moved to farrowing crate, (4) but another 16 sows in ESF moved to group farrowing pen. Behavior observation were conducted for 24 hours during the following time: first day in each sow housing treatment, day of service, 80 days after service, 109 days after service, day after farrowing, 14 days after farrowing, 27 days after farrowing, post weaning day. The results during pregnancy period showed that the sows kept in stall had significantly more standing (p<0.001), eating (p<0.05), drinking (p<0.001), dog-sitting (p<0.001) behavior and had significantly less moving (p<0.001), and lying (p<0.001) behavior. The results during lactation stage showed that the sows kept in small groups had significantly more standing (p<0.001), rooting (p<0.001), moving (p<0.001), but significantly less eating (p<0.01), dog-sitting (p<0.01), lateral lying (p<0.001), and nursing frequency (p<0.001). The present results also showed that the behavior was significantly different (p<0.001) among different physiology stages. The above results showed that the stall had a negative effect on the sow during pregnancy stage, although dog-sitting behavior had significantly more for sows raised in farrowing crates than group farrowing house.
