임신돈의 사육시설이 분만모돈의 분만성적에 미치는 영향

In this study we investigated the performance of sows reared under two different housing systems : single stall - farrowing crate (SSFC) and shoulder length barrier - farrowing crate (SLBFC). Two groups of pregnant sows (30 sows ⨯ 2 treatments ⨯ 4 seasons = 240 sows) were housed in individual stalls (SSFC) and shoulder length barrier (SLBFC) for twelve weeks respectively. All pregnant sows were then transferred to individual farrowing crates a week before parturition and were reared for four weeks. Average litter size, average birth weight, average litter weight, and body condition score (BCS) were measured and statistically compared using SPSS. Our results showed that there were no significant differences (p>0.05) on the farrowing performance of sows reared under SSFC and SLBFC. However, in this study, the welfare level of SLBFC is higher than that of SSFC. Therefore, we recommend that gestating sows must be housed in shoulder length barrier (SLBFC).
