Abstract

The aim of this study was to investigate the responses of growth performance, digestibility and blood biochemistry to the dose and administration method of enzymes. A total of 150 unsexed 1-d-old Arbor Acres broiler chickens were divided equally among 5 dietary treatments with 6 replicates per treatment and five chickens each. All experimental groups were fed the same basal diet and given 5 multienzyme treatments: The 1st group, the control group, did not receive multienzyme supplementations. The 2nd, 3rd, 4th and 5th groups were given multienzyme in water at 100 and 150% of the recommended dosage in drinking water given either continuously or intermittently methods, respectively. In the continuous method, the multienzyme is added to the water over the day. While, in intermittently method, the multienzyme is added to the water over the day followed by day off during the 1st through the 35th days of age. The addition of multienzyme either at 100 or 150% to water improves the growth performance and nutrient digestibility i.e. dry matter, crude protein and ether extract of broiler chickens compared with the control. However, 100% of multienzyme resulted in the best growth performance than that 150% multienzyme group. Intermittently administration exhibited significantly better growth performance and nutrient digestibility i.e. dry matter and NFE than those given multienzyme with continuously administration way. There were no significant effects of the multienzymes dose and the administration methods on carcass characteristics and blood biochemical constituentsexcepttriglycerides and creatinine. In conclusion, broilers received multienzymes at 100% intermittently in water exhibited significantly higher growth rate and significantly the best FCR. Production index was also the best of this group.
