熱季杜洛克公豬精液配送方式對母豬繁殖性能之影響
Effect of shipping method of Duroc boar's semen on reproductive performance of sows during hot seasons
摘要
本試驗之目的在探討熱季環境下目前三種主要精液配送方式:門市取貨、火車寄送與宅配服務對母豬繁殖性能之影響。杜洛克公豬精液採集後，經檢驗合格之稀釋精液，依不同配送方式寄至同一養豬場，行配種後調查母豬之受胎率、每窩出生總產仔數與每窩出生活仔數，共計調查母豬74頭。結果顯示：三種精液配送方式，於配送前後精子活力下降7－8%，但均可達活力70%的標準。門市取貨、火車寄送與宅配服務三種配送方式之母豬受胎率分別為89%、96%與92%，每窩出生總產仔數分別為9.8 ± 1.5頭、10.0 ± 2.8頭和9.4 ± 2.4頭，每窩出生活仔數則分別8.2 ± 2.3頭、8.9± 1.9頭和8.2 ± 1.9頭。本試驗中，不同配送方式對母豬每窩出生總產仔數與每窩出生活仔數在統計上沒有顯著性差異。綜合上述，在熱季環境下，以目前豬精液的處理流程而言，三種主要新鮮豬精液的配送方式均能有效的維持豬精液品質。

The objective of this study was to investigate the effects of three semen shipping methods on reproductive performance of sows during hot seasons. The diluted semen was delivered to pig farms by pick-up, train shipment and special delivery and the sows were then mated by artificial insemination. Seventy-four sows were randomly allocated into three groups and the reproductive data were collected and analyzed. The results showed that pigs born alive at birth by pick-up, train shipment and special delivery were 8.2 ± 2.3, 8.9 ± 1.9, 8.2 ± 1.9 head per litter and the litter sizes were 9.8 ± 1.5, 10.0 ± 2.8 and 9.4 ± 2.4 head and the conception rates were 89%, 96% and 92%, respectively. The reproductive performances of sows among three semen shipping methods showed no significantly differences. The three semen shipping methods could effectively maintain semen quality under a hot environment.
