摘 要：本实验旨在研究纳米硒对山羊生长性能、山羊抗氧化能力、生长激素和胰岛素的影响。选择体重相近(12±1)kg、体格健壮太行青山羊公羊90只，随机分为9组，分别喂以基础日粮和添加不同水平（0.03 mg/kg DM，0.05 mg/kg DM，0.1 mg/kg DM，0.3 mg/kg DM，0.5 mg/kg DM，1 mg/kg DM，3 mg/kg DM和5 mg/kg DM）纳米硒的饲料，实验期95d。结果表明：日粮添加纳米硒显著提高山羊的生长性能（P<0.05）、血清超氧化物歧化酶和谷胱甘肽过氧化酶活性（P<0.05），当添加水平在0.3 mg/kg DM ~1 mg/kg DM时，血清超氧化物歧化酶和谷胱甘肽过氧化酶活性保持高峰平台；日粮添加纳米硒显著降低血清谷胱甘肽硫转移酶活性和丙二醛含量（P<0.05），并在添加水平为0.3 mg/kg DM ~1 mg/kg DM时保持低谷状态；日粮添加纳米硒显著提高全血硒、生长激素和胰岛素的浓度（P<0.05）。结论：日粮添加0.3~1mg/kg DM，增强了山羊机体抗氧化功能，促进了生长激素和胰岛素的分泌，从而促进山羊的生长。

Abstract: The study was conducted to investigate the effect of different levels Nano-Se on growth rate, anti-oxidation function, growth hormone and insulin concentration in the goats. A total of 90 male goats with approximate body weight were allotted to the 9 groups randomly. Eight different levels Nano-Se were respectively supplemented to eight test groups in a dosage of 0.03mg, 0.05mg, 0.1 mg, 0.3 mg, 0.5mg, 1 mg, 3 mg, 5mg Nano-Se per kilogram diet dry matter respectively. Whole feeding experiment lasted for 95 days. Growth rate were very markedly higher than control group (P<0.05) at concentration range of 0.3 mg/kg DM ~1 mg/kg DM for Nano-Se; Serum glutathione peroxidase (GSH-Px) activity and superoxide dismutase (SOD) activity were very markedly higher than control group(P<0.05 ), which remained steady at the peak value at concentration range of 0.3 mg/kg DM ~1 mg/kg DM for Nano-Se. Serum glutathione-S-transferase (GST) activity, malondialdehyde (MDA)concentrations were markedly lower than control group (P<0.05), which kept the lowest value at concentration range of 0.3~1 mg/kg DM for Nano-Se; Blood selenium concentration, serum growth hormone and insulin concentration significantly higher than control group (P<0.05). It is concluded that supplementation of Nano-Se can improve the anti-oxidation function, increase growth hormone and insulin concentration, and increase growth rate in the goats. Supplementation level of Nano-Se is 0.3~1mg Nano-Se per kilogram basal diet for goats.
