The results showed that Digestrum had positive effects on final body weight, SGR and FCR so that in the treatment fed on 2 gr. The most final weight (6.8g±0.34), the best SGR (4.0±0.12) and the least FCR (1.1±0.22) were observed in the same treatment (p<0.05). The most number of Lactobacilli colonies, The best length of intestine villi (600.14+_15.44), villi across (105.14±2.18), and cript depth (55.2±2.10) were reported from this treatment too (p<0.05).
