The study aimed to compare the egg production and hatchability of local ducks under different management systems, namely semi-intensive and extensive. The research conducted was an experimental one-way classification with two treatments. Each treatment used 15 male and 120 females (mating ratio 1:8), and ducks aged 13-14 months. Eggs production was recorded during three weeks period. About 300 eggs were selected from each treatment to be hatched. Fertility was observed at 4 th days of hatching process using egg candler. Data of eggs production, eggs weight, fertility, and hatchability were analyzed using unpaired two sample Student ’ s t-test. The results showed that average of egg weight, fertility and hatchability were not different under two management system, but egg production in the semi-intensive maintenance was significantly higher (P<0.05) than those in the extensive system. Egg production in the semi-intensive was 12.3% higher than those in the extensive. In conclusion, the semi-intensive system that is applied in this study the number of eggs production but did not affect the average of egg weight, fertility and hatchability.
