The present study was conducted to determine the effects of energy-protein ratio in diets on Balinese duck performance and feed digestibility. A total of 120, 1-d-old healthy male Bali duck (Anas sp
) were randomly divided into four treatment groups: i) The ration contains metabolic energy (ME) 3150 kcal/kg with 22% crude protein as a control (A); the ration contains 3000 kcal/kg of metabolic energy with 20% protein (B); ration contains 2850 kcal/kg of metabolic energy with 18% (C) protein; and ration contains 2700 kcal/kg of metabolic energy with protein 16%(D), respectively.There were six replications per treatment, resulting in 24 pens, which contained 5 birds each. The results showed that there was no significant difference (P
>0.05) in feed intake, dry matter digestibility and protein digestibility between all treatments. Final body weight and live weight gains, the highest (P
<0.05) obtained in ducks fed ration A, conversely, the lowest was found in treatment D. Likewise, the lowest feed efficiency (P
<0.05) was found in ducks that were treated D.It was concluded that the decrease in metabolic energy and protein in the ration significantly decreased the performance of male Bali ducks in the starter phase and did not affect the digestibility of dry matter and protein ration.
