摘　　要：【目的】为提高海南黑山羊的生长和免疫性能,以南药诺丽为材料,开发一种新型免疫增效剂用于海南黑山羊的健康养殖,以期促进其产业的可持续发展。【方法】选取健康海南黑山羊54只,随机分为6个处理,试验期为60 d,分别在试验0、30、60 d测定各处理的生长性能和免疫指标。【结果】试验60 d高剂量诺丽处理比黄芪多糖处理和其他处理海南黑山羊的平均体重和日增重显著增长,且随着添加剂量的增加而升高;海南黑山羊血清总蛋白和球蛋白含量,黄芪多糖处理与添加诺丽的处理间差异不显著。而在试验30 d和60 d时,高剂量诺丽处理的血清IgG、IL-2和IFN-γ含量较其他处理略高,与对照差异显著,且随添加剂量增加而提高。【结论】每天添加20 g诺丽果粉饲喂海南黑山羊60 d为较理想的饲喂方案,其日增重可达97.27 (±20.87) g,且血清IgG、IL-2和IFN-γ含量分别为49.17 (±3.52) g/L、136.24 (±12.77) ng/L、112.72(±10.94) ng/L,诺丽可显著提高海南黑山羊的生长和免疫性能。诺丽在海南黑山羊绿色健康养殖及产业化发展中具有广阔的应用前景。【Objective】In order to improve the growth and immune performance of Hainan black goat,a new type of immune synergist was developed with Noni(Morinda citrigolia L.) as the material to promote the healthy breeding and sustainable industry development of Hainan black goat.【Method】Fifty-four healthy Hainan black goats were selected and randomly divided into 6 groups.The experimental period was 60 d,and the growth and immune performance of each group were measured on the 0 d,30 d and 60 d of the experiment,respectively.【Result】On the 60th day of the experiment,the average body weight and daily gain of the high-dose Noni group were significantly different from those of the Astragalus polysaccharide and other groups,and increased with the increase of the supplemental dose.In addition,there was no significant difference in serum total protein and globulin between Astragalus p.group and Noni group.On the 30th day and 60th day of the test,the serum levels of IgG,IL-2 and IFN-γ in the high-dose Noni group were slightly higher than those in the other treatment groups,which were significantly different from those in the control group,and they were increased with the increase of the additive dose.【Conclusion】Adding 20 g Noni powder every day and feeding for 60 days is the ideal feeding scheme,and the daily gain of Hainan black goat can reach 97.27(±20.87) g.The levels of IgG,IL-2 and IFN-γ are 49.17(±3.52) g/L,136.24(±12.77) ng/L and 112.72(±10.94) ng/L,respectively.Noni can significantly improve the growth and immune performance of Hainan black goat.Therefore,Noni has a broad application prospect in the green and healthy breeding and industrial development of Hainan black goat.
