DETERMINATION OF OPTIMAL METABOLISABLE ENERGY OF SUPER MEAT BROILER DUCK

ABSTRACT

Two studies were carried out to determine optimal metabolisable energy of super meat broiler duck, one study was done on duck 0-21 days with 5 ME diets: 2850, 2900, 2950, 3000 and 3050 kcal/kg feed.  Another study was done on duck 22-56 days with 5 ME diets: 2900, 2950, 3000, 3050 and 3100 kcal/kg feed. Base on parameters such as: body weight, average daily gain, average daily feed intake, FCR, feed cost/weight gain, carcass rate, breast rate, thighs rate and abdominal fat rate, we concluded that optimal metabolisable energy of super meat broiler duck raising in 0-21days stage and 22-56 days stage are 2850 kcal/kg feed and 2950 kcal/kg feed, respectively.
