To evaluate effects of tail docking and/or teeth clipping on sows and their piglets, a total of 24 sows and their 302 piglets at 3 days of age were randomly allocated to one of four treatments: teeth clipping and tail docking (TCTD), teeth clipping (TC), tail docking (TD), or intact teeth and tail (Intact). Behavior of piglets and sows, lesions on the body and tail of piglets and sows' teats were inspected. Heart rates of processed piglets were increased (p < .01) during the procedures. Teeth clipping decreased body surface temperature (p < .01) of piglets during and after the procedures but tail docking did not (p > .01). Processed piglets spent more (p < .05) time lying alone and playing/fighting than sham-processed piglets. Tail docked piglets spent less (p < .01) time standing than tail sham-docked piglets. Intact teeth increased (p < .05) the avoidance behaviors of sows. Teeth clipping decreased (p < .05) the lesion scores on the anterior, middle, and posterior teats. Taken together, piglet teeth clipping had more impact on sows and their piglets than tail docking did in the lactation period based on our findings.
为了评估断尾和/或剪牙对母猪及其仔猪的影响，将 24 头母猪及其 302 头 3 日龄仔猪随机分配到以下 4 种处理组之一：剪牙断尾（TCTD）、剪牙（TC）、断尾（TD）或完整牙齿和尾巴（Intact）。检查了仔猪和母猪的行为、仔猪和母猪尾部的损伤以及母猪乳头的损伤。处理后的仔猪心率增加（p<0.01）。剪牙会降低仔猪在处理过程中和处理后的体表温度（p<0.01），但断尾则不会（p>0.01）。与假处理仔猪相比，经过处理的仔猪独自躺着和玩耍/打架的时间更多（p<0.05）。断尾仔猪站立的时间比假断尾仔猪少（p<0.01）。完整的牙齿增加了母猪的回避行为（p<0.05）。剪牙降低了前、中、后乳头的损伤评分（p<0.05）。综上所述，根据我们的研究结果，与断尾相比，哺乳期仔猪剪牙对母猪及其仔猪的影响更大。
