The objective of this research was to study the effect of restricted feeding period and refeeding on muscovy duck performance in the starter period. This study used 100 male day-old duck of Muscovy ducks that were kept for 1 day to 9 weeks of age. This study used a Randomized Block Design (RBD) with 5 treatments and 4 replications. The ratio given was 30% of the normal ratio. The treatment of restricted feeding period were ad libitum (A), 1 week (B) 2 weeks (C) 3 weeks (D) and 4 weeks (E) The variables observed were feed consumption, body weight gain, feed conversion (FCR) protein intake, growth rate, carcass and carcass percentage. The results showed that feed restriction had a very significant effect (P<0.01) on feed consumption and FCR but had no significant effect (P>0.05) on protein intake, feed conversion ratio (FCR), growth rate, carcass, and carcass percentage. It can be concluded that treatment D (3-week restriction) showed the best performance with a feed consumption of 903.64 g/head/week, a body weight gain of 170.18/head/week, FCR 5.72, a carcass of 843 g, and a carcass percentage of 57.88%.
