1、VENTILATINGPOULTRYHOUSESDURINGCOLDWEATHER冬季雞舍通風(fēng)YANTAIBernardGreenWhyWeVentilate為什么要通風(fēng)Weventilateto:通風(fēng)是為了:Createanairexchange空氣交換Controlmoisturelevels(relativehumidity/RH)控制濕度Supplyoxygen提供氧氣Removeharmfulgases(CO?,CO,NH?)排出有害氣體Controltheheatload控制熱量積聚Controlthebirdeffectivetemperature控制雞群
2、體感溫度Combinationoftemperature,relativehumidity,airspeed,birdage溫度、濕度、風(fēng)速及雞的年齡綜合作用AlwaysventilatetoachieveandmaintainBIRDCOMFORT通風(fēng)始終要達(dá)到并保持雞群舒適HowWeVentilate如何進(jìn)行通風(fēng)Atorbelowsetpointtemperature→minimumventilation低于設(shè)定溫度---最小通風(fēng)Regardlessofoutsidetemperature,acertainamountoffreshairmustbebroughti

5、ispriority!雞群舒適最重要!WhenDoWeUseMinVent?什么時(shí)候采用最小通風(fēng)Itcanbeusedsummerandwinter可以在夏季及冬季使用Itisusedanytimetheactualhousetemperatureisbelowtherequiredsetpointtemperatureforthebirds雞舍溫度低于理想的設(shè)定溫度時(shí)就可以使用Itisusedwhentryingtomaintaintemperature,butstillputtingtheleastamountoffreshairpossibletomaintain
6、goodairquality為了保持溫度但是還需要一定的新鮮空氣進(jìn)入雞舍一保持空氣質(zhì)量Whenthehousetemperaturegoesabovetherequiredsetpointtemperature,thenitisnolongerinminimumventilationmode當(dāng)雞舍的溫度超過設(shè)定的要求溫度時(shí),就不再進(jìn)行最小通風(fēng)SetPointTemperature設(shè)定溫度MinimumVentilation最小通風(fēng)TransitionandTunnelVentilation過渡及縱向通風(fēng)BirdRequirements雞只需求Warmfloordurin
