Abstract: To study effect of compound recipe andrographitis on the structure of intestinal mucosa of Arbor Acres. 240 Arbor Acre broilers of one day old were divided into four treatments: A, B, C and control group. Experimental group supplemented with different production by requirement in the rage of Arbor Acres from 1 to 42 days of age. Taking intestinal tract of 7, 35 and 42 days broiler, measured the villi height, crypt depth, intestinal paries thickness. The results showed that: A, B group have significant increased in villi height（P＜0.05）; crypt depth has significant decreased（P＜0.05）;35 days’ C group have significant increased in intestinal paries thickness（P＜0.05）. The results indicated that compound recipe and rographitis have significantly increased villi height, decreased crypt depth and intestinal paries thickness.
