Effect of Compound Recipe Andrographitis on the Structure of Intestinal Mucosa of Arbor Acre Broilers

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(P0.05);crypt depth has significant decreased(P0.05);35 days' C group have significant increased in intestinal paries thickness(P0.05).The results indicated that compound recipe and rographitis have significantly increased villi height,decreased crypt depth and intestinal paries thickness.
