摘要
Farrowing pens with temporary crating have been developed as a compromise between conventional farrowing crates and pens to better accommodate the welfare of both sow and piglets during lactation. However, not much is known about the behavioral and physiological consequences of early removal of confinement on the sow and piglets during lactation. The aim of this study was to assess the effects on sow and piglet performance of temporary crating until 3-d postpartum at 2 times points, immediately after confinement removal and 25 d into lactation. Sows were crated from 5-d prepartum either to weaning (permanently crated—PC group; N =14) or to D3 (83.0 ± 1.3 h) postpartum (Temporarily crated - TC group N = 13). Sow postural changes, activity, cortisol and IgA concentrations, and piglet body weight gain and behavior were assessed on D4 and on D25 postpartum, whereas piglet mortality was assessed throughout lactation. Data were analyzed using PROC GLM and PROC GENMOD of SAS. On D4 postfarrowing, TC sows were more active (10.9% vs. 7.1%; SEM: 0.8; P = 0.002), rolled more frequently (21.3% vs. 14.4%; SEM: 1.6; P = 0.008), and had lower IgA concentrations (139.7 vs. 75.2 μg/mL; SEM: 20.3; P = 0.040) than PC sows. No effects of housing were found (P > 0.05) on standing-to-lying movement or cortisol concentrations. No differences for any variables were found (P > 0.05) on D25. Mortality, body weights, and activity levels at the udder or in the pen of pigs born to PC sows did not differ (P > 0.05) from those of piglets born to TC sows on D4 nor on D25. This study indicates that removal of confinement on the 4th-d postpartum may have had small short-term positive effects on sow behavior and stress levels (as measured by IgA), and that it did not impair piglets’ behavior and performance during lactation. Therefore, this work suggests that temporary crating limited to the first 3-d postpartum might be a feasible alternative to improve welfare under intensive production conditions.

已开发出带有临时板条箱的分娩栏，作为常规分娩板条箱和围栏之间的折衷，以更好地适应泌乳期母猪和仔猪的福利。但是，对于泌乳期间尽早清除母猪和仔猪的行为和生理后果知之甚少。这项研究的目的是评估临时围栏直到产后3天，分娩后和泌乳25天后的2个时间点对母猪和仔猪生产性能的影响。母猪从产前5天到断奶（永久定殖）PC组。 N = 14）或产后D3（83.0±1.3 h）（临时创建— TC组N = 13）。在产后D4和D25评估母猪的体态变化，活动，皮质醇和IgA浓度以及仔猪体重增加和行为，而在整个泌乳期评估仔猪死亡率。使用SAS的PROC GLM和PROC GENMOD分析数据。在D4产后，TC母猪更活跃（10.9％比7.1％； P4）。扫描电镜：0.8； P = 0.002），更频繁地滚动（21.3％对14.4％；扫描电镜：1.6； P = 0.008），且IgA浓度较低（139.7对75.2μg/ mL；扫描电镜：20.3； P = 0.040）。没有发现住房对站立到躺着的运动或皮质醇浓度的影响（P> 0.05）。 D25各变量均无差异（P> 0.05）。在第4天和第25天，PC母猪出生的仔猪的死亡率，体重和活动水平与TC母猪出生的仔猪的乳房或围栏的死亡率没有差异（P> 0.05）。这项研究表明，在产后第4天取消分娩对母猪的行为和应激水平（以IgA衡量）可能具有较小的短期积极影响，并且这并未损害仔猪在泌乳期间的行为和表现。因此，这项工作表明，仅限于产后前3d的临时板条箱可能是在集约化生产条件下改善福利的可行替代方案。
