The aim of this study was to demonstrate the effect of using feed treated with enzymes on some anatomical characteristics in rumen of lambs. This study was conducted in the animal field/ College of Agriculture/ University of Basrah. Sixteen Arabi male lambs aged 4-5 months and weighted 22.25 kg were used. Lambs were randomly distributed into four treatments, with four animals for each treatment. The concentrated diet was mainly consisting of 54% barley, 30% bran, 10% ground yellow corn, 5% soybeans, and 1% vitamins and mineral salts. Lambs were fed 3% of their live body weight. The studied diets consist of 60% concentrated feed and 40% of roughage without or with the addition of 10 gm of lignin peroxidase enzyme, or 40% of the concentrated feed and 60% of the roughage as well without or with the addition of the enzyme. The groups fed a diet supplemented with enzymes showed significantly high papillary length, breadth, and surface area of the rumen (P<0.05) compared to the control group. The results also showed a significant effect (P<0.05) on the amounts of feed consumed and the weight gain in the groups fed a diet supplemented with enzymes compared to the control group. I
