摘要:

为探究硒代蛋氨酸(SM)在高氟诱导氧化应激条件下对肉鸡机体生理状态的调控作用,本试验以氧化应激的黄羽肉鸡为研究对象,评价饲粮中添加SM对其生长性能、免疫指标及血清生化指标的影响。试验选用720只1日龄岭南黄羽肉雏鸡,随机分为4组:对照组(CON)、氟化钠(HF)组、亚硒酸钠(SS)组和SM组。其中HF组在基础饲粮中添加800 mg·kg-1氟化钠,SS组和SM组在HF饲粮基础上分别补充0.15 mg·kg-1 SS和SM。试验周期为56 d。结果表明,与CON组相比,HF组平均日增重显著(p<0.05)降低,料重比显著升高,血清免疫球蛋白水平及免疫器官指数显著下降,同时血清丙氨酸氨基转移酶活性、天冬氨酸氨基转移酶活性、乳酸脱氢酶活性、葡萄糖含量和尿酸含量显著升高。与HF组相比,补硒可在不同程度上改善上述指标,其中SM在改善生长性能、免疫指标及缓解血清生化指标异常方面的效果优于SS。综上,高氟诱导的氧化应激条件下,饲粮中添加硒代蛋氨酸有助于缓解氧化应激对黄羽肉鸡生理功能的不利影响。

Abstract:

To investigate the regulatory effect of selenomethionine(SM)on the physiological status of broilers under high fluoride-induced oxidative stress conditions,this experiment selected yellow-feathered broilers with oxidative stress as the research subjects,and evaluated the effects of adding SM to the diet on growth performance,immune indicators,and serum biochemical indicators. 720 one-day-old Lingnan yellow-feathered broilers were randomly divided into 4 groups:control group(CON),sodium fluoride (HF) group,sodium selenite(SS) group,and SM group. The HF group added 800 mg·kg-1 sodium fluoride to the basal diet,while the SS group and SM group supplemented 0.15 mg·kg-1 SS and SM on the basis of the HF diet. The experimental period was 56 days. The results showed that compared with the CON group,the average daily weight of the HF group was significantly(p<0.05)reduced,the feed-to-weight ratio was significantly increased,the serum immunoglobulin levels and immune organ indices were significantly decreased,and the serum alanine aminotransferase activity,aspartate aminotransferase activity,lactate dehydrogenase activity,glucose content,and uric acid content were significantly increased. Compared with the HF group,selenium supplementation could improve the above changes to varying degrees. Among them,SM was superior to SS in improving growth performance,immune indicators,and alleviating abnormal serum biochemical indicators. In summary,under high fluoride-induced oxidative stress conditions,adding SM to the diet can help alleviate the adverse effects of oxidative stress on the physiological functions of yellow-feathered broilers.
