This study aimed to evaluate whether adding straw to a loose-farrowing house promotes maternal functions and production. Forty-eight sows (Landrace× Large White) were housed in either a farrowing pen without straw (C, n = 24) or with straw (S, n = 24). Behaviors were observed using video recordings and were statistically analyzed. Lateral recumbency was higher and standing was lower in S compared with C (p = .034 and p = .020, respectively), and lateral recumbency to other postures, ventral to lateral recumbency and standing to lying were markedly lower in S than C (p = .014, p = .025 and p = .023, respectively) on Day 1 postpartum. However, except piglet losses during the first three days postpartum (p = .032), piglet weight on Day 21 (p = .037), and piglet weaning weight (p = .020), other production performances were not significantly different between the two groups during the whole experimental period (p ˃.05). The results suggest the enrichment of a farrowing pen with straw has important beneficial effects on sow and piglet welfare and improves piglet survival rates.

这项研究旨在评估向散乱的农舍中添加秸秆是否能促进产妇的功能和生产。将四十八头母猪（Landrace×大白）放在不带秸秆（C，n = 24）或带秸秆（S，n = 24）的分娩猪舍中。使用录像观察行为并进行统计分析。与C相比，S的侧卧位较高，站立时较低（分别为p = .034和p = .020），S的侧卧位，其他姿势，腹侧向卧位和卧位至卧位均显着低于C（产后第1天分别为p = .014，p = .025和p = .023）。但是，除了产后前三天的仔猪损失（p = .032），第21天的仔猪体重（p = .037）和仔猪断奶体重（p = .020），在整个实验期间，两组之间的其他生产性能没有显着差异（p˃0.05）。结果表明，用秸秆富集产仔猪对母猪和仔猪的福利具有重要的有益作用，并提高了仔猪的成活率。
