Phytase was produced from a fungus Aspergillus niger through 10-day fermentation in a maize starch-based medium. Activity of the enzyme was found to be 1.075 phytase units per minute per ml of the crude culture ®ltrate, at pH 5.5 and 408C. A 4-week feeding trial was conducted on 90-day-old broiler chickens, fed on diets based on maize and soyabean meal, to study the ef®cacy of phytase enzyme on growth performance, apparent availability of P and Ca, tibia-and-toe ash and mineral contents of… CONTINUE READING
