Abstract

The objectives of this study were applying environmental control technologies for comparing the reproductive capacity, the reproductive period and the adjusted period of the breading geese among three production types. A total of 7136 White Roman geese (5947 female geese and 1189 male geese) at 68 weeks of age were randomly divided into period adjustment with a water pad windowless building set (set A), natal period adjustment with traditional open building set (set B) and natural period with traditional open building set (set C). The experimental results indicated that the laying period of the set A, set B and set C are 177, 94 and 147 days respectively. The average laying rate, hatchability and fertilization rate of set A were the highest, but there were not significantly different among three sets (p > 0.05). The average egg production number per female goose for set A was 55 eggs which was the highest. The average product gosling number per female goose of the set A was 41 birds which was more than that of set B (19 birds) and that of set C (26 birds). Therefore, the laying period of goose could be successful adjusted to the non-breeding season and extended it with the water pad environment of control building for reducing summer temperature and short light time.
