Abstract

A 10-week feeding trial was conducted at the University Animal Farm, ADSC, CA, UP Los Baños using a total of forty-eight 23-week old Philippine mallard ducks to determine the effects of different dietary energy levels (2600, 2700, 2800, 2900, 3000, and 3100 kcal ME/kg) on egg production performance specifically on hen-day egg production, egg weight, egg mass, average daily feed consumption, and feed efficiency. Ducks were randomly distributed to six treatments following completely randomized design with eight replicates per treatment. Data were analyzed using analysis of variance and treatment means were compared using Tukey?s Studentized Range (HSD) test. Results showed that diet with 2800 kcal ME/kg had the highest egg production and egg mass for the duration of the study (23-32 weeks). Ducks fed diet with 3000 kcal ME/kg had the lowest egg production and egg mass which was attributed to its large final body weight. There were no significant treatment effects on the egg weight and feed efficiency of the ducks. However, significant differences were observed on egg mass and feed consumption. Increasing the energy content of the diet beyond 2800 kcal ME/kg did not improve egg production and egg mass. Based on the results of the study, the optimum dietary energy level for laying ducks from week 23 to 32 is 2800 kcal ME/kg.
