Two varieties of Hybrid napier (CO-3 and CO-2) were compared at three stages of harvest (60, 90 and 120 days) on yield, chemical composition and in vitro dry matter and organic matter digestibility. The CP content ranged from 7.28 to 10.60 percent on DM basis. The in vitro digestibility values showed that the fodder could be fed at maintenance as well as for production purposes. Based on forage yield, chemical composition and nutrient digestibility it was observed that CO-3 variety was superior to CO-2 variety. Maximum nutrients were available at 60 days of harvest, however, the total bio-mass yield was highest at 120 days of harvest.
