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

目的是防止鴨子下河并減少污染。我們已經(jīng)進行了預(yù)測試，并且不接觸水的鴨子的產(chǎn)卵率緩慢上升。一般來說，產(chǎn)蛋率在50％~60％之間不會上升。因此，我們挖小池塘的作用是減少干面條的影響。小池塘不是太大。挖一個10平方米的池塘就足夠了2000只鴨子。池塘的深度為20厘米。泳池水每天都很容易更換，可以用小泵抽水。池水中還有一些鴨子，為期3天。鴨子在夏天每天發(fā)射3到4次，每次發(fā)射10分鐘。讓鴨子在水后放在陰涼處;每天2次，冬季，上午10點，下午3點左右，每次5分鐘，允許水后，鴨子在運動場曬日光浴。如果天氣太冷，如果天氣太冷，澆水的次數(shù)和時間應(yīng)相對減少。或者不要下水。

不同年齡雛鴨的率差異很大。隨著年齡的增長，小鴨體內(nèi)的病毒可以增強，并且si的率降低。 6.該病主要與甘，沙門氏菌，曲霉菌，鋸緣青蟹和黃病毒混合或。 7.發(fā)病率高達100％，可導(dǎo)致95％至100％的雛鴨。這種疾病全年都在發(fā)生。大多數(shù)小鴨突然發(fā)病，表現(xiàn)出抑郁，食欲不振，頭部下垂，后出現(xiàn)神經(jīng)系統(tǒng)癥狀，如抽搐和頸背。他們不在路上，眼睛半閉，半閉，顯示，腳不穩(wěn)，頸部呈拱形。背部表現(xiàn)為運動障礙，身體轉(zhuǎn)向一側(cè)，翅膀下垂，兩只腳反復(fù)踢。在顏炎正的陪同下，有不同程度的腹瀉，綠色或白色液體稀薄的糞便，泄殖腔常有糞便，并迅速。
