Umbilical hernias (UH) are common in pigs and are an animal welfare concern. This study used an assessment of play behavior to evaluate the welfare of pigs with UH. Twenty-one grower pigs with UH and 17 without hernias (WUH) were assigned to 16 playing groups (PG) of 2 or 3 pigs (with at least 1 UH pig per PG). The time each animal was engaged in any of the defined playing behaviors for locomotor/social or toy play behaviors was recorded. Mixed Poisson or negative binomial and linear models were used to determine the effect of UH and day of session, accounting for the cluster of pigs within groups, on the frequency of each play behavior, and playing times. Pigs with UH had the same frequency of most play behaviors and playing times as pigs without hernias. There was no indication that the presence of UH-affected play behavior or performance in pigs.
脐疝（UH）在猪中很常见，并且是一个动物福利问题。本研究通过对玩耍行为的评估来评价患有脐疝的猪的福利状况。将21头患有脐疝的生长猪和17头无疝猪（WUH）分配到16个玩耍组（PG）中，每组2或3头猪（每个PG组至少有1头患有脐疝的猪）。记录每只动物参与任何一种定义的运动/社交或玩具玩耍行为的时间。使用混合泊松或负二项式以及线性模型来确定脐疝和试验日对每组猪群中每只猪的每种玩耍行为频率和玩耍时间的影响。患有脐疝的猪与无疝猪的大多数玩耍行为频率和玩耍时间相同。没有迹象表明脐疝的存在会影响猪的玩耍行为或表现。
