Abstract:
Background: The Alabio duck (Anas platyrhynchos Borneo) is one of the natural genetic resources that has the
potential to be a superior type of laying duck in South Kalimantan. The purpose of the study was to examine egg
production, duck feed conversion, and the physical quality of Alabio duck eggs at different ages during the
production period of the first egg-laying period.
Materials and Methods: The research was conducted at the Poultry Breeding Center (BPTU) in Tanah Laut
Regency, South Kalimantan. The materials used in this study were 5 flocks of female Alabio ducks (each with
about 500 heads of ducks per flock) with different ages: 6 months, 9 months, 12 months, 15 months, and 18
months.
Results: The percentage of egg production was affected by the ages of Alabio ducks; the highest yield was at 9
months of age (87.60%) and the lowest at 18 months (47%) with an all-term first-period production average of
71.92%. The feed conversion ratio was affected by the ages of the Alabio ducks. The lowest FCR value was the
9-month age group (2.67) and the highest was the 18-month age group (4.64). The ages of the group have an
effect on egg weight, egg shape index, yolk percentage, albumen percentage, percentage of eggshells, shell
thickness, HU, yolk index, and albumen index, but have no real effect on yolk color.
Conclusion Overall, 9-month-old Alabio ducks produce the highest egg production, the lowest feed conversion,
and the best egg quality in averages.
