摘　　要：旨在研究手术去势后包扎对仔公猪创口愈合、行为、生产性能和血液指标的影响。选择体况良好、体重相近的杜长大仔公猪224头,随机分为3组,分别为假去势组(A组)、去势包扎组(B组)和去势不包扎组(C组)。仔公猪在5日龄进行无麻醉手术去势,21日龄断奶时试验结束。分别在仔公猪去势及包扎后对创口愈合、行为表现、死亡率、生产性能、血清皮质醇(COR)和免疫指标进行评估。结果表明:去势后5 d内,C组仔公猪创口愈合程度的评分显著高于B组(P<0.05);去势极显著降低仔公猪站立、玩耍和探究等行为(P<0.01),极显著增加仔公猪独处、惨叫、抱团、异常排尿、站立不稳和恐人等行为(P<0.01),而创口包扎对仔公猪玩耍和恐人行为有明显改善;在整个试验期内,B和C组仔公猪的断奶重和平均日增重(ADG)与对照组均无显著差异(P>0.05),去势造成哺乳期仔公猪的死亡率升高,但通过对创口包扎,B组仔公猪在去势后5 d内死亡率(1.35%)明显低于C组(6.41%);在去势后3 d内,B和C组仔公猪COR浓度均极显著高于对照组(P<0.01),而在第5天时B组COR浓度显著低于C组(P<0.05);在去势后3 d内,B和C组仔公猪血清免疫球蛋白A(IgA)和免疫球蛋白G(IgG)浓度均极显著低于对照组(P<0.01),而去势后第5天时,B组IgA浓度显著高于C组(P<0.05),白介素-12(IL-12)和干扰素-γ(IFN-γ)浓度在去势前后均无显著差异(P>0.05)。上述结果表明,手术去势造成仔公猪强烈的疼痛应激,而术后包扎可显著降低去势引发的创口红肿出血和感染死亡,加快创口愈合,缓解疼痛造成的行为变化,促进血液指标恢复,从而保障仔公猪的福利水平。This study aimed to explore the effects of bandaging or not after surgical castration on wound healing,the animal behavior,production performance and blood index of male piglets.Two hundred and twenty-four Duchang male piglets with good health and similar weight were randomly divided into 3 groups,sham operation(group A),wound bandage(group B)and no bandage(Group C)groups were set up.The male piglets were castrated without anesthesia at the age of 5 days and then the related indexes were detected until the age of 21 days.Wound healing,animal behavioral performance,mortality,production performance,serum cortisol(COR)and immunity index were evaluated after the ending of castration and bandaging on male piglets.The results showed that the scores of wound healing degree in the male piglets of group C were significantly higher than those in group B(P<0.05);the behaviors of standing,playing and exploring were significantly reduced(P<0.01)and the behaviors of being alone,screaming,hugging,abnormal urination,unstable standing and fear of man were extremely significantly increased(P<0.01)after surgical castration without bandaging.Wound bandage had obvious effects on the behavior of playing and fear of man;There was no significantly difference between group B and C in the weaning weight and average daily gain(ADG)during the entire test period(P>0.05).Although the mortality caused by surgical castration were increased,the mortality rate of(1.35%)group B was significantly lower than group C(6.41%)within 5 days after surgical castration;The concentration of COR in both group B and C were significantly higher than that of the group A(P<0.01)while the secretion of immunoglobulin A(IgA)and immunoglobulin G(IgG)in serum were significantly lower than group A(P<0.01)within 3 days after surgical castration;However,by the fifth day,the concentration of COR in group B was significantly lower than group C(P<0.05)and the secretion of IgA and IgG in group B were significantly higher than group C(P<0.05)and there was no significantly dif
