| Summary: | The usefulness of carbohydrate hydrolyzing enzymes in animal feeds and their potential utilization in broiler diets was Investigated. A 42-day of feeding trial involving 44, one week day old Cobb 500 broiler was carried out, in a completely randomized design (CRD) to evaluate the growth characteristics using enzymes at a dietary level of 0.07% Natugrain (T1), 0.07% Digestase (T2) and 0.035% Natugrain + 0.035% Digestase (T3) meals. Daily feed intake, body weight and growth rate of feed conversion ratio was determined for each diet. Proximate analysis of starter feed was carried out. Results showed that daily feed intake was increased in 12 (0.07% Digestase) on 21 days of age until 42 days of age. T1 (0.07% Natugrain) was also showed increase in daily feed Intake compared to control diet for the last two weeks of
experiment. However, T3 (0.035% Natugrain + 0.035% Digestase) showed a decrease in daily feed intake on 42 days of age. There was significance difference (p<0.05) for
body weight. Average body weight in 12 was Significantly higher compared with control, T1 and T3. Feed conversion ratio (FCR) of experimental birds in T1, T2 and 13 was also within a good range in 35 to 42 days of age (1.64 - 1.97) compared with control. It is suggested that the inclusion of these hydrolytic enzymes in diets could be used in broiler commercial feed to enhance feed Intake and to promote weight gain to broiler chicken.
