Abstract

For suitable nutrition according to the requirements of Alabio male ducks, it is necessary to balance metabolic energy and protein. The purpose of the study was to analyze the effect of the energy and protein balance (E/CP) on the growth achievement and carcass quality of Alabio male duck. The feeding trial study was conducted in a poultry house for six weeks. The research method used a completely randomized design (CRD) with factorial pattern where is the first factor being metabolic energy+y level (E) consisting of E1: 2800 kcal/kg ME, E2: 2900 kcal/kg ME, E3: 3000 kcal/kg ME, while the second factor was crude protein level (CP) consisting of P1: 15 CP, P2: 16 CP, P3: 17 CP, with three replications, where each replication consisted of five ducks with a total of 135 male Alabio ducks. The observed variables were final body weight (BW), body weight gain (BWG), feed intake (FI), feed conversion ratio (FCR), carcass percentage, carcass fat, and abdominal fat. The data obtained have been analyzed by analysis of variance (ANOVA) method. The results showed that there was an interaction between (E) and (CP), where the best results were obtained in the combination of E2P3 treatment with an E/CP ratio of 17.1 (ME 2900 kcal/kg, 17 CP), including BW at 1185.0 g/bird, BWG at 1134.0 g/bird, FI at 3563.21 g/bird, and FCR at 3.14 and the lowest carcass quality with the highest carcass percentage reaching 67.33, and the lowest carcass fat and abdominal fat were 0.37 and 0.75, respectively. It was concluded that the effect of E/P ration at ratio of 17.1 gives the best result on the performance of male Alabio ducks including the achievement of BW, BWG, FI and FCR, and carcass quality through the achievement of increasing carcass percentage, decreasing carcass fat and fat abdominals. © 2021.
