密度问题，但养鸭的过程中一定要注意饲养密度不宜过大，这样容易导致鸭苗受潮，空气污染，引起病理反应，如果密度过小，就会浪费人类资源和减少经济效益。因此，适合密度为7天的小鸭每平方米提高34，小鸭每天提高25平方米，直到第20天小鸭可以减少到15平方米，直到满月龄的小鸭，每平方米可提高10个，也应根据季节调整，冬季密度可略微增加，夏季应减少。小鸭幼苗生长45天后，有必要进行分组饲养，一些较为健壮的鸭苗和生长较差的雏鸭分开管理。有必要隔离患病的鸭子并观察雏鸭的状态。积极采取措施。
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
托盘中的卵和孵化鸭孵化26天，并将活胚蛋放在托盘上。放置托盘后，应根据孵化蛋的温度和湿度要求控制温度和湿度。也就是说，与先前的培养阶段相比，温度适当地降低，并且适当地增加湿度以促进孵化。为了确保足够的湿度，应适当增加水盘的数量以保持水盘清洁，以便水可以蒸发。鸭蛋将孵化至孵化的第27.5天。在孵化29天后，小鸭将被保存在孵化场中，直到羽毛变干，然后取出并放入育雏室或盒子中。雏鸡太早，幼羽不干燥，对环境的适应性差;年幼的小鸡为时已晚，幼羽在干燥后会干燥，小鸭可能会自行爬出并落入水盘并淹死。在孵化期间，应尽可能少地关闭灯，并且只有当小鸡被点燃时，才能避免在幼雏爬行时损坏关节。通常在2小时内接一次。
