冬季鴨苗，如何預(yù)防疾病，gan是一種快速傳播和高度致命的病毒傳播的雛鴨，病原體是鴨瘟病毒。它的特點(diǎn)是病程短，且角弓逆轉(zhuǎn)的臨床表現(xiàn)，病變主要是g脹和出血點(diǎn)。在自然條件下，該病主要發(fā)生在3周齡以下的雛鴨中。成年鴨子可以在沒(méi)有發(fā)病的情況下運(yùn)行，但可以通過(guò)糞便排出，污染環(huán)境和染色的易感鴨子。該病一年四季都會(huì)發(fā)生，喂養(yǎng)和管理不當(dāng)，鴨舍溫度過(guò)低，密度過(guò)高，衛(wèi)生條件差，缺乏維生素和礦物質(zhì)可以促進(jìn)疾病的發(fā)生。本病病病潛伏期短，僅1-2天。小鴨子突然生病了。起初，病鴨表現(xiàn)出，頸部變窄，翅膀下垂。它無(wú)法與團(tuán)隊(duì)一起移動(dòng)，眼睛半閉，打瞌睡和共濟(jì)失調(diào)。該病發(fā)生在半天至一天，并發(fā)生全身抽搐。身體倒在一邊，兩只腳反復(fù)踢踢，大約十分鐘就死了。頭部回到背部，角的解剖姿勢(shì)稱為“后頸部疾病”。痰和爪的是深紫色，一些生病的鴨子在它們之前是黃色，白色和綠色和糞便。

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.
