鸡仅能消化吸收27%的饲料营养,其余大部分排泄出体外,可供鱼类直接利用。特别是对那些体长不到10cm食性以浮游生物为主的鲢、鳙、青、鲤等鱼苗,鸡粪肥水可培育大量的浮游生物,为鱼苗提供了食饵。 鸡粪饲料应用方法:先将鸡粪发酵,之后再均匀地泼洒鱼池内,以施肥代替投喂豆浆或精料。经试验表明,利用鸡粪培育鱼种,一般每亩年产鱼种可达200~
Chickens can only digest and absorb 27% of feed nutrition, most of the remaining excreted, available for direct use of fish. Especially for those body length of less than 10cm diet plankton mainly carp, bighead carp, blue carp and other fry, chicken manure can cultivate a large number of plankton for the fry to provide prey. Chicken manure application methods: first chicken manure fermentation, and then evenly splashed fish ponds to fertilize instead of feeding soy milk or concentrate. The test shows that the use of chicken manure breed species, the general production of fish per acre up to 200 ~
