摘　　要：本试验旨在研究橡胶籽油(RSO)对热应激肉鸡生长性能及血浆生化、抗氧化和免疫指标的影响。选取1日龄爱拔益加(AA)肉仔鸡864只,随机分为4组,每组12个重复,每个重复18只鸡。对照组饲喂基础饲粮(含1%大豆油),试验组分别饲喂含1%(Ⅰ组)、2%(Ⅱ组)和4%RSO(Ⅲ组)的试验饲粮。各组均在高温环境[(34±2)℃]饲养,试验期42 d。结果表明:1)与对照组相比,Ⅰ组、Ⅱ组和Ⅲ组42日龄体重极显著升高(P<0.01),1~42日龄平均日采食量(ADFI)和平均日增重(ADG)极显著升高(P<0.01),1~42日龄料重比(F/G)极显著降低(P<0.01)。2)与对照组相比,Ⅰ组和Ⅲ组血浆总蛋白(TP)含量显著降低(P<0.05),Ⅰ组、Ⅱ组和Ⅲ组血浆白蛋白(ALB)、总胆固醇(TC)、三碘甲状腺原氨酸(T3)和四碘甲状腺原氨酸(T4)含量显著或极显著降低(P<0.05或P<0.01),Ⅱ组和Ⅲ组血浆丙氨酸氨基转移酶(ALT)活性显著降低(P<0.05),Ⅰ组和Ⅱ组血浆碱性磷酸酶(ALP)活性显著降低(P<0.05)。3)与对照组相比,Ⅰ组、Ⅱ组和Ⅲ组血浆丙二醛(MDA)含量显著降低(P<0.05),Ⅰ组、Ⅱ组和Ⅲ组血浆总超氧化物歧化酶(T-SOD)活性显著升高(P<0.05),Ⅱ组和Ⅲ组血浆总抗氧化能力(T-AOC)显著升高(P<0.05)。综上所述,饲粮中添加RSO可改善热应激肉鸡生长性能,提高机体免疫和抗氧化能力。The purpose of this experiment was to evaluate the effect of rubber seed oil(RSO)on growth performance and plasma biochemical,antioxidant and immune parameters of broilers under heat stress.A total of864 one-day-old Arbor Acres(AA)broilers were allotted to 4 groups with 12 replicates in each group and 18broilers in each replicate.Broilers in the control group were fed a basal diet(contained 1 soybean oil),and the others in experimental groups were fed experimental diets contained 1%(groupⅠ),2%(groupⅡ)and 4%RSO(groupⅢ),respectively.Broilers in all groups were fed in a high temperature environment[(34 ±2)℃],and the experiment lasted for 42 days.The results showed as follows:1)compared with the control group,the body weight at 42 days of age of groupⅠ,groupⅡand groupⅢwas significantly increased(P<0.01),the average daily feed intake(ADFI)and average daily gain(ADG)during 1 to 42 days of age were significantly increased(P<0.01),and the feed to gain ratio(F/G)during 1 to 42 days of age was significantly decreased(P<0.01).2)Compared with the control group,the plasma total protein(TP)content of groupⅠand groupⅢwas significantly decreased(P <0.05),the contents of albumin(ALB),total cholesterol(TC),triiodothyronine(T3)and tetraiodothyronine(T4)in plasma of groupⅠ,groupⅡand groupⅢwere significantly decreased(P<0.05 or P <0.01),the plasma alanine aminotransferase(ALT)activity of groupⅡand groupⅢwas significantly decreased(P<0.05),and the plasma alkaline phosphatase(ALP)activity of groupⅠand groupⅡwas significantly decreased(P<0.05).3)Compared with the control group,the plasma malondialdehyde(MDA)content of groupⅠ,groupⅡand groupⅢwas significantly decreased(P<0.05),the plasma total superoxide dismutase(T-SOD)activity of groupⅠ,groupⅡand groupⅢwas significantly increased(P<0.05),and the plasma antioxidant capacity(T-AOC)of groupⅡand groupⅢwas significantly increased(P<0.05).In conclusion,dietary supplemented with RSO can improve the growth performance,immune and antioxidant capa
