Abstract
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<0.05) in performance and ALP activity between male and female chickens. The group, that received IPB D1 diets with 80 ppm ZnO/kg and 500 FTU phytase/kg, had higher body weight and feed conversion ratio (FCR) than the other groups. However, feed consumption and ALP activity were not significantly different. Overall, adding zinc oxide and phytase to the diets of local chickens was found to improve their performance and ALP activity.
