肩部溃疡影响母猪母性行为

    DENMARK - Shoulder ulcers in lactating sows lead to changes in behaviour such as shorter lying time, increased restlessness and lower nursing frequency, according to an investigation conducted by Aarhus University and the Danish Pig Research Centre.

　　The study was based on observation of 19 sows with shoulder ulcers and 19 without sows for a 24-hour period approximately two weeks after farrowing.It also showed that affected sows had less contact with their young compared with healthy sows without shoulder ulcers. Sows with ulcers also showed greater rubbing of the shoulder against the fittings than the healthy sows. Although sows two weeks after farrowing are motivated to nurse and care for their young, the investigation showed that their maternal behaviour was affected. Overall, the results can be interpreted as the sows attempting to ease pain or discomfort through frequent changes in posture and by spending less time lying.

　　丹麦——一项由丹麦奥尔胡斯大学猪研究中心进行的调查研究表明，哺乳期母猪肩部溃疡会导致行为的变化，如躺卧时间变短、不安情绪增加和喂奶频率降低。    

　　这项研究基于对19头有肩部溃疡的母猪和19头分娩后大约两个星期的母猪24小时内的观察。它还表明，感染的母猪和健康且没有肩部溃疡的母猪相比，它们更少接触幼体。和健康的母猪相比，有溃疡的母猪也表现出更多的肩部摩擦。虽然母猪产仔两周后更愿意为照顾、护理幼体，调查显示，它们的母性行为受到影响。总的来说，结果可以解释为母猪通过频繁的姿态变化或较短的躺卧时间，试图减轻疼痛或不适。
