为了详细掌握我国北方蛋鸡生产和环境控制的现状及具体参数,本研究团队对河北省养殖密集地区的鸡舍类型及基本结构情况,蛋鸡生产配套设施基本情况进行了详细的调查,结果显示,鸡舍外围结构以花墙式为主,占72%;鸡舍屋顶结构类型以平屋顶为主,占77%;鸡舍材料以砖混结构为主,占53%。通风方式以自然通风利用率最高,清粪方式以人工清粪为主。说明样本调查区的分户散养模式下的鸡舍存在建筑及设施简陋,生物安全没有保障,不利于环境控制和疫病防治等特点。为实现蛋鸡产业升级,有必要对现有鸡舍进行改造。
In order to get a detailed grasp of the current situation and specific parameters of laying hens production and environmental control in the north of China, the team conducted a detailed investigation on the types and basic structure of chicken coops and the basic facilities of laying hens in the intensive breeding areas in Hebei Province. The results showed The external structure of the house was mainly flower wall, accounting for 72%. The roof structure of the house was dominated by flat roof, accounting for 77%. The house was mainly made of masonry, accounting for 53%. Ventilation mode to maximize the utilization of natural ventilation, manure cleaning methods to clear the main man-made. This indicates that the chicken coop under the mode of separated households and free-range farming in the sample survey area is characterized by poor construction and facilities, no guarantee of biological safety and adverse environmental control and disease prevention and control. In order to realize the industrial upgrading of laying hens, it is necessary to reform existing hen houses.
