Abstract
The invention relates to a method for preparing a feed for river crabs. The feed comprises the following components in percent by weight: miscellaneous fish meal, river mussel meal, chicken blood meal, silkworm meal, potato flour, rice flour, duckweed meal, hydrilla varticillata, tape grass meal and alternanthera philoxeroides. The feed has low preparation cost and can be fed to the young and adult river crabs to take a good effect. The river crabs fed by the feed can grow quickly, can be large in size and fat and are not easy to be affected by diseases. The feed effectively overcomes the defects of the existing feeds which are shorts of various nutritions, are easy to lead to the slow growth and development, small size, light weight and less activity of the river crabs, have poor palatability and can cause the river crabs to be susceptible to various diseases.
Description
Technical field
The present invention relates to a kind of compound method of crab feed, particularly a kind of compound method of river crab breeding feed belongs to the breeding feed technical field.
Background technology
River crab also cries " crab " or " eriocheir sinensis ", before breeding migration, is young crab, and is yellow because of its shell colour cast, is commonly called as " yellow crab "; River crab is to grow in the fresh water, and the crab class of breeding in the seawater is educated at fresh water relaying supervention and to be grown up river crab formal name used at school Eriocheir sinensis; The expensive freshwater product of generic name, Fresh & Tender in Texture, delicious flavour; Nutritious, be the food simply that is loved by the people, have very high economic worth.
At present, popularizing along with agalactous, all is to be main feeding method with mixed feed; Because the nutrition in the batching contains quantity not sufficient, the content of various albumen and vitamin is lower, is prone to cause the shortage of protein, fat, carbohydrate, mineral matter and vitamin powder and the trace element of river crab; River crab is because the deficiency of various nutrition is prone to cause river crab to grow slowly, and stature is little, in light weight, activity is few; Agreeable to the taste poor performance is prone to suffer from various illnesss.
Summary of the invention
The objective of the invention is to provide a kind of: the cost cost; Various nutrition reasonable mixture ratio are fit to the river crab compound method of a kind of river crab breeding feed of growth fast, overcome in the existing feed because the deficiency of various nutrition; Be prone to cause river crab to grow slowly; Stature is little, in light weight, activity is few, agreeable to the taste poor performance, the easy defective of suffering from various illnesss.
The technical solution adopted for the present invention to solve the technical problems is: a kind of compound method of river crab breeding feed; It by: trash fish powder 35%45%, freshwater mussel powder 10%-15%, chicken blood meal 3%-8%, dried silkworm chrysalis meal 5%-9%, dehydrated potato powder 6%13%, paddy meal 5%-9%, duckweed grass meal 8%17%, hydrilla verticillata 2%-3%, eel grass powder 1%-2%, water peanut 1%-3% form, and described percentage is weight percentage.
In proportion above-mentioned substance is poured in the pulverizer and pulverized, put into mixer after the taking-up and stirred 180 minutes, produce the hard particles feed with ring mode grit unit then, sieve with 40 meshes, every weight is 0.15 gram.
Beneficial effect: this prescription selects for use multiple material formulated, and albumen and multivitamin content are abundant in the feed, and the ratio between the various nutritions is moderate; River crab can both be satisfied fat, carbohydrate, coarse-fibred demand in the feed, has reached the object of the invention.Above-mentioned river crab breeding feed, the cost cost is low, the river crab fast growth; To young crab with become crab to feed good effect is all arranged, raise substantially fertilizer of the crab that comes, and the rate of falling ill of crab is low; Effectively overcome in the existing feed because the deficiency of various nutrition is prone to cause river crab to grow slowly, stature is little, in light weight, activity is few; Agreeable to the taste poor performance, the easy defective of suffering from various illnesss.
