利用畜牧业副产品或废弃物发展农、渔、工、副业生产,既可节约大量的饲料,又可获得显著的经济效益、生态效益和社会效益。下面介绍几种高效养殖模式,供农友择用。“鸭—鹅—鱼”模式。用竹网圈拦水面养鸭鹅,每平方米水面放鸭3～4只或鹤1～2只。1只鸭年产粪40～50公斤,可转化产成鱼3～5公斤。1亩水面配养蛋鸭100～200只、肉鸭100～120只、鹅50～70只,以其粪便及残落的饲料养鱼,可产鲜鱼300～500公斤。
The use of livestock by-products or waste development of agriculture, fisheries, industry, sideline production, can save a lot of feed, but also access to significant economic, ecological and social benefits. Here are several efficient breeding mode for farmers to use. “Duck - goose - fish ” mode. With bamboo net ring water surface duck, goose, duck per square meter of duck 3 ~ 4 or 1 ~ 2 cranes. A ducks annual output of 40 to 50 kg, can be converted into fish 3 to 5 kg. 100 ~ 200 ducks, 100 ~ 120 ducks and 50 ~ 70 geese will be raised on the 1 mu of water surface. With its excrement and its residual feed, it will produce 300 to 500 kilograms of fresh fish.
