Action taken at this stage will prevent difficulties at later stages in dealing with the consequences of poor uniformity and poor development of essential physiological functions‖ “在育雛早期階段，任何時間出現(xiàn)體重不達標或食欲不振的跡象，應(yīng)立即采取相應(yīng)措施。 High brooding temperatures 育雛溫度太低或太高 – Temperature Vs Humidity Interaction 溫度和濕度相互影響 So What’s the Problem? 會產(chǎn)生什么問題？ ? Hot: 太熱 – Drink More 飲水量增加 – Eat Less to reduce metabolic heat output 采食量減少 以減少代謝熱的產(chǎn)生 – Pant (Heavy/Light)嚴重喘氣或輕微喘氣 – Dilate blood vessels 血管擴張 ? Cold: 太冷 – Sit down 不愿活動 – Huddle up 擠堆 – Eat more to increase metabolic heat output 采食量增加 以增加代謝熱的產(chǎn)生 – Contract blood vessels 血管收縮 Too Cold 太冷 13 What Happens when Chicks Get Cold? 當雛雞受涼時會發(fā)生什么？ ? Blood Temperature Decreases 血液溫度下降 ? Chicks Get Colder 雛雞體溫下降 ? Metabolism Increased To Compensate 增加代謝量來彌補 ? Activity Decreased 活動量減少 ? COLD STRESS 冷應(yīng)激 2 3 . 9 癈3 7 . 8 癈242628303234362 5 .214 “Rule of Thumb” “一般原則” ? 24 hrs in normal climates ? 正常氣候預(yù)溫 24小時 ? 48 hrs in cooler times ? 溫度較低季節(jié)預(yù)溫 48小時 ? 72 hours in cold winters ? 寒冷冬季預(yù)溫 72小時 Preheating 預(yù)溫 Achieve 29C Litter Temperature on Arrival 雛雞到達時墊料溫度應(yīng)高于 29度 15 Too Hot 太熱 16 Air Temperature 空氣溫度 Hum
