Global warming brings about increasing the risk of ducks to be more succeptable to heat stress which leads to decrease welfare and production. This research aimed to study duck welfare and productivity under probiotic and antioxidants administration at commercial farms. The method used was experiment with Completely Randomized Design based on factorial pettern. The treatment was dose of natural/home made and commercial probiotics combined with vitamin C at 400 and 600 mg/kg feed. Thus there were 4 treatment combinations. Each treatment was replicated 5 times, as a result there were 20 flocks of duck. Each flock had 50 laying females so there were 1,000 ducks involved. The treatment was applied for two months. Parameters observed were (1) duck welfare based on H/L ratio; (2) egg production consisted of (a) Duck Day Production, and (b) egg weight. This study concluded that administration of combination between homemade probiotic and vitamin C at 600 mg/kg feed significantly increased duck welfare and egg production but did not affect egg weight.
