【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.
