摘　　要：选择1日龄健康樱桃谷SM3系商品代肉鸭18 490羽,随机分为网上(N组)和发酵床上(B组)2组进行饲养,监测冬季一个完全生长周期内(42d)鸭舍温度(T)、相对湿度(RH)及温湿指数(THI)变化,探讨不同养殖模式对商品肉鸭舍温湿指数的影响。结果表明:N组和B组舍内平均温度均明显高于平均气温;N组舍内温度全部高于B组,N组平均温度比B组高8.32℃,差异显著(P<0.05)。N组和B组舍内相对湿度均明显高于室外;N组舍内平均相对湿度比B组高2.47%,无显著性差异(P>0.05)。试验期N组有16d处于热应激状态,B组有6d处于冷应激状态。结果提示,在北方寒冷气候下网上供暖养殖模式能为商品肉鸭提供更舒适的温湿度条件。18 490 1-day-old healthy Cherry Valley SM3 meat ducks were randomly divided into 2groups to be cultivated on wire netting（group N）and fermentation bed（group B）.Changes of temperature（T）,relative humidity（RH）and temperature and humidity index（THI）of duck shed were monitored for a whole growth period（42days）in winter.The results showed that both the inside average temperature of group N and group B was significantly higher than that of outdoors;The temperatures of group N were averagely 8.32 ℃ higher than that in group B,indicating significant difference（P〈0.05）.Both the inside average relative humidities of group N and group B were significantly higher than those in outdoors;and the average relative humidity of group N was 2.47% higher than the group B,but with no significant difference（P〉0.05）.During the whole experimental period,there were 16 days under heat stress in group N and 6days under cold stress in group B.All the results suggested that wire netting feeding could provide more comfortable temperature and humidity conditions for meat ducks in cold northern China.
