Analyzing the impact of a combination of zinc oxide and phytase on the performance and alkaline phosphate activity in local chickens

This study aimed to determine the effect of adding a combination of zinc oxide (ZnO) and phytase to the diet of local chickens (IPB D1) on their performance and alkaline phosphatase (ALP) activity. A total of 120 male and female chickens were divided into four dietary groups, with 24 cages of five birds each. Each group was fed using: a pure basal diet; a basal diet with 80 ppm ZnO/kg feed; a basal diet with 80 ppm ZnO/kg feed and 500 FTU phytase/kg feed; a basal diet with 80 ppm of commercial ZnO/kg feed and 500 FTU/kg feed of commercial phytase. The chickens were grouped by sex and body weight, with three classes of weight uniformity. The results of this research showed that there was a significant difference (p
