PROBLEM TO BE SOLVED: To provide a chicken breeding apparatus capable of breeding a larger number of chickens well in a more comfortable environment and increasing egg production efficiency without being affected even by heat wave, thus contributing to reducing production costs.SOLUTION: A plurality of poultry house buildings each being longitudinally elongate and defined internally by a partition plate into an air inlet chamber and a return duct chamber along its longitudinal direction are provided. A breeding block is disposed in the air inlet chamber of each of the plurality of poultry house buildings and comprises breeding gauges arranged longitudinally along the air inlet chamber for housing many chickens. One air-conditioner building is connected to one end of each of the plurality of poultry house buildings to suck in returning heat-exchanged air from the return duct chamber to exchange heat and to blow out temperature-controlled cold or warm air into the air inlet chamber in place of the heat-exchanged air. A curved duct portion is provided at the other end of each of the plurality of poultry house buildings to guide the heat-exchanged air from the air inlet chamber to the return duct chamber.COPYRIGHT: (C)2014,JPO&INPIT【課題】より大量の鶏を、より快適な環境で、元気に飼育することができ、たとえ猛暑時においても影響を受けることがなく、産卵効率を向上させて生産コストの低減に寄与する鶏の飼育装置が望まれていた。【解決手段】長手方向に長く、かつ長手方向に沿って内部が仕切り板にて導風室と戻りダクト室に区画される複数の鶏舎棟を備える。飼育ブロックは、複数の鶏舎棟の導風室に配置され、多数の鶏を収容する飼育ゲージを導風室に沿って長手方向に並べられたものである。1つの空調装置棟は、複数の鶏舎棟のそれぞれ一端部に接続され、戻りダクト室から戻りの熱交換空気を吸込んで熱交換し、温度制御した冷気もしくは暖気の熱交換空気に換えて前記導風室へ吹出す。曲がりダクト部は、複数の鶏舎棟のそれぞれ他端部に設けられ、導風室から戻りダクト室へ熱交換空気を案内する。【選択図】図1
