在傳統豬隻生產系統中,母豬常被飼養於空間狹小且缺乏刺激的環境,容易產生慢性緊迫,影響其健康與福祉,並進一步影響後代表現。本專討之目的為探討懷孕母豬飼養系統及懷孕期與哺乳期的環境豐富化對母豬及其仔豬福祉、生理與生產效益的影響。懷孕母豬若飼養於群養系統(GS)而非個體夾欄(IS),可展現出更多的自然行為,體內的緊迫反應相關激素(如ACTH與腎上腺素)顯著較低;其仔豬在免疫測試下的恢復力較佳,緊迫反應較小,顯示群養能改善母豬及仔豬的健康狀況。在懷孕期(第6至14週)母豬提供環境豐富化可顯著降低初產母豬的緊迫反應,改善其分娩行為,並提升仔豬離乳體重,顯示環境豐富化有助於緩解分娩相關緊迫。除此之外,在分娩欄內提供母豬與仔豬豐富化設施,有助於減少母豬褥瘡的發生並改善仔豬的皮膚健康(如淚痕與皮膚病變)。整體而言,群養制度及環境豐富化措施不僅能增進懷孕或哺乳期母豬之福祉,亦有助於提升其後代健康與生產效益,對現代養豬業具有正向影響。
