An approach to reproductive failure in pigs, based on the regular collection and analysis of performance records is proposed. Inovlvement at this level gives veterinary surgeons familiarity with herd mangement and economics. The use of control charts to monitor performance is also advocated for detecting problems as they arise. When failure occurs, a stage-by-stage clinical investigation of the whole breeding programme is advisable. Post mortem studies may also be useful in detecting specific pathological changes. Diagnostic tests should only be used to confirm diagnoses. Having established the source and extent of the failure, and its likely cost, if uncorrected, appropriate measures can be considered. Three principal methods of control are discussed.
本文提出了一种基于定期收集和分析生产记录来解决猪繁殖障碍问题的方法。兽医参与到这一过程中，有助于他们熟悉畜群管理和经济情况。本文还提倡使用控制图来监测生产性能，以便在问题出现时及时发现。当繁殖障碍发生时，对整个繁殖计划进行分阶段的临床调查是可取的。尸检研究也可能有助于发现特定的病理变化。诊断测试仅应用于确诊。在确定了繁殖障碍的根源、范围及其可能的成本（若不加以纠正）后，便可考虑采取适当措施。本文讨论了三种主要的控制方法。
