蛋鸡高密度叠层笼养工艺的初步研究

Study on High Density Stacked Cage Raising System of Layer

蛋鸡叠层笼养工艺具有节约土地、减少环境污染、降低饲养成本、提高投资利用率和劳动生产率等优点，饲养密度达４８．３～６０只／ｍ２，料蛋比２．２～２．５∶１，死淘率低于１５％，与三层全阶梯笼养相比，可节约土地６３．４８％，提高劳动生产率１６０％～２９０％。

The high density, stacked cage raising system can significantly save land, reduce the environmental pollution,cut down raising cost, raise investment utilization ratio and working efficiency. It will be a new direction of future development to raise layers for its efficiency and economy. The raising density is 48 3～60 layers/m 2,working efficiency is increased 160%～290% than old raising system.
