摘要
湘黄种鸡露天散养时,合理的光照以提高产合格种蛋率是露天散养的重要技术之一。本研究采用人工光照与自然光照结合办法,对4个批次7 400套种鸡进行了研究观察,并与对应的同日龄全自然光照专业户鸡群比较,得出散养种鸡制定出合理的光照程序可使产合格蛋率提高21.93%。
It is an importance technic for Xianghuang seed hen when scatter-feed, right illumination program basis elements of illumination for increase seed egg. In the research, 7 400 Xianghuang seed hen(4 groups) be observed. The illumination means combine manpower with nature, and compared with seed hen food al farmer' s with nature illumination. It is known the rate of eligible egg increased to 21.93 %.
