EGG PRODUCTION AND HATCHABILITY OF LOCAL DUCKS UNDER SEMI INTENSIVE VS EXTENSIVE MANAGEMENTS
Abstract: 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 4th 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.
