Survey Report on the Welfare of Piglets in Scaled Pig Farms
摘要
Abstract
This special investigation aimed to survey the practices of injurious management procedures in piglets and the reasons for non-use of analgesia on large-scale pig farms in China.A designed question-naire was distributed via the QuestionSar platform,and statistical analysis was performed on data from 330 pig farms with complete information,at least 10 sows,and the presence of piglets.The results showed that:(1)The proportions of farms performing tail docking,teeth clipping/grinding,and surgical castra-tion in piglets were 90.0％,45.8％,and 94.2％,respectively.Among these,90.9％,94.0％,and 70.4％respectively performed these procedures within 0～7 days of age,while 46.1％,36.4％,and 40.5％respec-tively used analgesia,indicating substantial room for improving pain mitigation management.(2)The pro-portion of farms using analgesia during tail docking,teeth clipping/grinding,and surgical castration was significantly higher(by more than 24％)on farms that emphasized animal welfare compared to those that did not(P＜0.05).(3)The prevalence of tail docking was significantly higher in breeding stock farms,farms with＞2 500 sows,and farms where the labor quota per worker was＞300 pregnant sows,com-pared to farrow-to-finish farms,farms with ≤2 500 sows,and farms with a labor quota of ≤300 pregnant sows,respectively(P＜0.05).In contrast,the prevalence of teeth clipping/grinding showed a significantly opposite trend(P＜0.01).(4)The proportions of surgical castration performed within 0～7 days of age or accompanied by analgesia were significantly higher in northern farms and farms with＞2 500 sows,com-pared to southern farms and farms with ≤2 500 sows,respectively(P＜0.05).(5)The top two reasons for not using analgesia during tail docking,teeth clipping/grinding,and surgical castration were"analgesic use increases labor costs"and"no suitable analgesics available",accounting for 55.2％～57.3％and 35.4％～47.0％of responses,respectively,and these were influenced by certain farm background factors.In con-clusion,injurious management procedures such as tail docking and surgical castration are very common on pig farms,but analgesia is used in less than half of these cases,indicating significant potential for impro-ving pain mitigation.These practices are influenced by farm background factors such as herd size.Enhan-cing the emphasis on animal welfare,advocating for performing injurious procedures within 0～7 days of age,and strengthening the use of analgesia are expected to reduce pain associated with these management practices and improve the health and welfare level of piglets.关键词
