Abstract: Effect of different Chinese herbal compound on production performance and immune function of Yunling black goat was evaluated in this study. 120 adult ewes with close birth date and weight were randomly divided into 4 groups by 30 per group, in which one was chosed as the control group and the other 3 groups as treatments (adding 1.2% of concentrate with Echinacea extract compound, four gentlemen powder and strong powder in the feed, respectively). The experiment included preliminary trial period (7 d, 1/4 of trial amount was added in the first 2 d, 1/3 of it was added in the second 2 d, 2/3 of it was added in the third 2 d, all trial amount was added in the 7th day) and trial period (60 d). All adult ewes were weighed fastingly on the morning of the 0, 30th and 60th day, recorded the total gain, average daily gain, and calculated the feed conversion ratio and the economic effectiveness. 1) In groupⅠ, the total weight gain and average daily weight gain were both the highest, with the value of 6.17 and 0.103 kg, which were 17.97% and 6.18% higher than that of control group respectively, but those of other 2 treatments were both lower compared to the control group; 2) In groupⅠ, the feed conversion ratio was 1.96: 1, and it was lower than that of the control group and groupⅡ by 7.09%, 17.76% and significantly (P<0.05) lower than that of group Ⅲ by 45.01%; 3) In groupⅠ, the net profit of sheep was the largest with the price of 4.25 Yuan/(d·ewe) which was 15.76% higher compared to the profit 3.58Yuan/(d·ewe) gained from the control group; 4)The number of red blood cell (RBC) and hematocrit (HCT) apparently increased in groupⅠ(P<0.05), the number of white blood cell (WBC) was higher by 3.98% than that of the control group, and the number of RBC also increased greatly in groupⅡ(P<0.05); 5) The serum total protein (TP) and globulin (GLB) of groupⅠand Ⅲ were significantly higher than those of the control group (P<0.05), also the Serum TP was 11.65% and 12.33% higher than that of the control group respectively, and the GLB of the two groups increased by 27.25% and 22.16%; 6) The serum cholesterol (CHO) of the 3 treatments was less than that of the control group (P>0.05), and compared to the control group, the CHO content of groupⅠ,Ⅱand Ⅲ decreased by 15.25%, 2.12% and 6.78%, respectively; 7) In groupⅠand Ⅲ, the immunoglobulin G (IgG) content was higher than that of other groups, especially higher than that of the control group by 3.5 and 1.3 times respectively. In conclusion, the Echinacea extract compound can promote production performance and the immune function of Yunling black goat, and it also increases the economic benefit.
