Cihateup duck is one of the local duck which coming from Cihateup village, Tasikmalaya District, West Java- Indonesia. This bird is very good for laying ducks with production of about 280-300 eggs. Some constraints because of limited agricultural land, as well as agricultural intensification, resulting land fallow period after harvest has in a short and limited and commonly full of pollution with pesticides. That situation makes duck productivity going down or low. For this condition requires much effort to overcome the real problem by maintaining ducks used ration and water efficiently as a priority. The research were divided into two phases, where the first phase was done to determine the efficiency of protein utilization value (EUP) dietary by means of excreta collection, and to define the requirement standard of protein and energy during growth. Twelve female ducks at 8 weeks old were used by using Scott et al. (1982) formula and carried out in two week. The second phase was aimed to evaluate the protein and energy diet levels during growth period. The protein in energy diet 300 kcal/kg was standard requirement and 2% of protein in energy diet just the same was evaluated. A Completely randomized design with four replications was used in this experiment. The parameters were feed consumption, body weight gain , feed conversion for the growth period, and age at first egg laid. Feeding trial was used 48 female Cihiateup ducks at 3 weeks old, and was carried out up until 20 weeks. The result indicated that efficiency utilization protein (EUP) dietary as big as 54.14%. The Protein and Energy requirement of female Cihateup ducks for starter, grower I and grower II phase were respectively need 17.75 percent of protein, 2,454.57 Kcal/kg; 11.79 percent of protein, 2,122.81 Kcal/kg; 7.17percent of protein and 2,207.30 Kcal/kg. Based with the two phase period, it can be concluded that female Cihateup ducks can be raised with the low energy (2,200 kcal/kg ME) and low protein (12.0%) in the growing (20 weeks) diet without any ill-effects on feed intake, body weight gain, feed conversion and the age of first lay.
