The cold insulation performance of the duck house should be excellent. The roof should have ceiling or heat insulation. The north wall should not leak air. The height of the eaves is 2.6~2.8 meters. The ratio of window to ground area is 1:8. The area of the south window is comparable. The north window is 1 times larger, the south window is 60-70 cm above the ground, and the north window is 1 to 1.2 meters high from the ground. In order to make the summer well ventilated, the north side can open the foot and window. But without glass, only iron bars or lead wire mesh are installed to prevent animal damage. In the cold season, it is sealed with tarpaulin or plastic cloth to prevent air leakage. In addition to setting up drainage ditch, there is also a place for breeding ducks to lay eggs in the evening. Single-row type duck house, the walkway is on the north side, the drainage ditch is next to the walkway, the barbed wire or wooden strip is covered, the drinker is placed on the wire mesh, and the south side is on the side of the wall. The terrain is slightly higher, and the nest box can be placed. The egg laying box is 30 cm wide and 40 cm long. It is nailed with wooden boards, without bottom, and the front is lower for the ducks to enter and exit. The other three sides are 35 cm high, and the bottom of the box is covered with wood chips or short clean mats. Each box can be used for 3 egg type ducks or 4 meat type ducks.xx
种翻鸭/后备番鸭饲管要点
9～24周龄为后备种番鸭。应选留体大健壮的公、母番鸭作后备种番鸭，公母比例1∶4～5。后备种鸭应限制饲喂，降低饲料营养水平，适当控制体重。种母番鸭产蛋前体重可控制在2.3～2.8kg，同龄公番鸭则为4～5kg，日粮代谢能11.29～11.70MJ/kg，粗蛋白14%～16%，每只鸭每天平均用料100～150g，喂青料25～50g，临开产时，可适当增加日粮粗蛋白质和代谢能水平，以便逐渐过渡到产蛋期营养水平，保证产蛋期有较高的产蛋量。xxxx
