The aim of this study was to investigate management and strategy-related risk factors for the occurrence of postpartum dysgalactia syndrome (PDS) in commercial pig herds. A questionnaire was sent to 250 pig herdsmen. Of the responding herdsmen (n=110), 37 reported occurrences of PDS, whereas 73 reported no cases of PDS. Data were then analysed using logistic regression. After univariate analysis, eight variables associated with PDS (P<0.2) were retained and these were used to construct a multivariable logistic regression model. Four significant risk factors were found: (1) moving pregnant sows to the farrowing unit 4 days or less before expected farrowing (Odds Ratio [OR] 6.272); (2) farrowing induction (OR 4.804); (3) feeding sows ad libitum during lactation (OR 3.149) and (4) frequent farrowing supervision (OR 0.085). This study has demonstrated that a considerable number of modern pig herds still suffer from problems with PDS, and that control measures should include optimising management and feeding practices.
本研究旨在调查商业猪场产后无乳综合征（PDS）发生的管理和策略相关风险因素。我们向 250 位猪场主发放了问卷，其中 110 位回复了问卷，其中 37 位报告了 PDS 的发生，73 位报告没有发生 PDS。然后我们使用逻辑回归分析数据。在单变量分析后，保留了与 PDS 相关的 8 个变量（P<0.2），并使用这些变量构建多变量逻辑回归模型。发现了四个显著的风险因素：（1）在预计分娩前 4 天或更短时间内将怀孕母猪转移到分娩单元（优势比[OR]6.272）；（2）诱导分娩（OR 4.804）；（3）哺乳期母猪自由采食（OR 3.149）和（4）频繁的分娩监护（OR 0.085）。本研究表明，相当多的现代猪场仍存在 PDS 问题，控制措施应包括优化管理和饲养实践。
