卵，鴨和鵝的育雛期是指0至6周齡，這是卵，鴨和鵝整個(gè)生長(zhǎng)過(guò)程中的重要階段。業(yè)內(nèi)有一種“終生5周”的說(shuō)法。這一階段不僅影響小鴨和鵝的成活率和生長(zhǎng)，而且影響未來(lái)產(chǎn)蛋的生產(chǎn)性能。為了成功培育和培育你的節(jié)目中的小鴨和鵝，有必要找出育雛期間的問(wèn)題并解決它們。 1，鴨鵝優(yōu)質(zhì)鴨鵝的質(zhì)量與育雛的成敗有關(guān)。當(dāng)鴨子和鵝被引入鴨子和鵝時(shí)，通常很難理解事實(shí)。因此，要抓好產(chǎn)區(qū)疫情調(diào)查，了解產(chǎn)區(qū)生存率和均勻度。鴨鵝養(yǎng)殖場(chǎng)應(yīng)有《種畜禽生產(chǎn)經(jīng)營(yíng)許可證》，管理規(guī)定，鴛鴦鴨苗價(jià)格，無(wú)重大流行病，白利，白雪病等疾病已經(jīng)凈化，并持有原產(chǎn)地檢疫證書。

The effect of temperature on feathers is particularly evident in management. In the autumn and winter， if the temperature suddenly becomes low， and the heating fails to keep up， or in the cold winter， the heating conditions of the duck house nei are too bad， causing the temperature inside the house to be too low， which can cause the duck to be feathered. And accompanied by a sharp drop in egg production. At the same time， the temperature of the ducklings during the brooding process is too high， which will make the ducklings not have long hair on a large area of the skin for a long time. Once an obstacle occurs in the drinking water system， it will cause long-term water loss. The ducks will be defeated under such severe stress， accompanied by a decrease in egg production or an outbreak of other diseases. In addition， the ventilation is poor， the ducks are stimulated by harmful gases for a long period of time; or the light is too strong， and the density and humidity are too large， which can cause the ducks to feed on the feathers of their own bodies or other ducks， thus causing serious paralysis. Feathers that are common in the tail and back are detached.xx
