The healthy Hy-Line Brown chickens of 12-day-old were divided into three groups randomly. The chickens in group 1 and 2 drank the water with 0.5% and 1% Chinese herbal medicine immunopromoter every day. The chickens in group 3 as control drank pure water. The Harder＇s glands of the chickens from 0.5% group, 1% group and control group at 24, 36 and 48 d after drinking medicine respectively were made into histological section. And then the histological sections were observed histologically. The results showed that Chinese herbal medicine could increase the quantity of the immunocells in glandular organs conspicuously. Immunopotentiator of Chinese herbal medicine could promote the amount and growth of secreted immunoglobuline and elevate the immune level of the orgamsm, and the effect of 1% group was higher than that of 0.5% group.展开更多

Founded in 1978, the company used to be an original equipment manufacturer for foreign big names. Facing faltering demand and decreasing profit margins after the financial crisis since 2008, the company made a tough decision to change its business model, which later enabled it to transform to an original design manufacturer and finally an original brand manufacturer.展开更多
