Abstract

The invention discloses winkle feed and a preparation method. The winkle feed is characterized by comprising, by weight percentage, dried waste fish or fish meal, soybean cake powder, bran, rice husk, vegetable leaves, grass meal, bone tankage, animal visceral meal and shell powder. The method includes: taking the substances according to the proportion, respectively sufficiently grinding the substances, sieving via a 80-mesh sieve, beating the vegetable leaves into vegetable slurry, feeding the raw material powder and the vegetable slurry together into a fish feed mixing machine for mixing for 50 minutes, using a special fish feed circular mould pelletizer to prepare pallet feed with the particle size of 2 millimeters, and airing the feed prior to bagging and packaging. The winkle feed is prepared from multiple feed raw materials in a proportioned manner, provides a feed basis for winkle production, and is reasonable in proportioning of animal protein and vegetable protein in components, rich in nutrient components, and beneficial to digestive absorption of winkles to the various nutrient components. The feed prepared by the formula is easily available to raw materials, good in palatability, easy for digestion and fast in absorption, and the winkles are fast in growth, high in disease resistance and high in cultivation survival rate.

Description

River snail feed and compound method

Technical field

The invention belongs to the aquatic feeds field, be specifically related to river snail feed and compound method.

Background technology

River snail is Fresh ﹠ Tender in Texture good to eat, unique flavor, and delicious flavour, nutritious, rich in protein, and be rich in fat and phosphorus, calcium, ferro element and vitamin, be the first-class health foods of people; The river snail happiness inhabits the water environment that bed mud is rich in humus, in the stream water body as pasture and water lake in great numbers, pond, low-lying area, field or unhurried current, normal is food with phytoplankton, young tender water plant, moss in the microorganism in the earth and humus and the water, also like anthropophagy worker's feed, as vegetables and fruits, dish leaf, rice bran, wheat bran, bean powder (cake) and various tankage.

According to surveying and determination: river snail edible part 100 grams contain moisture 81 grams, protein 10.7 grams, fat 1.2 grams, carbohydrate 4 grams, ash content 3.3 grams, 1357 milligrams of calcics, phosphorus 19l milligram, 19.8 milligrams of iron, 0.05 milligram of thiamine, 0.17 milligram in riboflavin, 2.2 milligrams of niacins, retinol1 30 international units approximately.

The traditional Chinese medical science is thought: the river snail flavor is sweet, salty, cool in nature; Can relieve heat and thirst, inducing diuresis for treating strangurtia makes eye bright, and removing jaundice is used for quenching one's thirst, liking drinking-water; Oedema, difficult urination, heat is drenched; Hot eyes heat pain; Jaundice symptom.

River snail is nutritious, edible, medical value is high, become the aquatic products that people like food gradually, market river snail product is in great demand, along with the river snail purposes more and more widely, the catching intensity of river snail also strengthens thereupon, it is imperative to propagate river snail artificially, river snail has become the important kind of aquaculture, the man-made feeds demand of river snail also continues to increase, only depend on wild feed not only to be difficult to satisfy the river snail requirement, also might cause the accumulation of disease, make river snail become the carrier of parasite, pathogen and can not eat.

Summary of the invention

For overcoming above-mentioned defective, the present invention has designed river snail feed and compound method.

Technical scheme of the present invention is, river snail feed and compound method, it is characterized in that, described feedstuff and proportioning: dried trash fish or fish meal 15%-20%, soya-bean cake powder 5%-10%, wheat bran 10%-14%, rice bran 15%-18%, dish leaf 14%-18%, grass meal 8%-12%, animal tankage 5%-7%, pluck powder 8%-13%, oyster shell whiting 1%-2%, described percentage is weight percentage.

As preferred version, river snail feed and compound method, described feedstuff and proportioning: dried trash fish or fish meal 20%, soya-bean cake powder 5%, wheat bran 14%, rice bran 15%, dish leaf 18%, grass meal 8%, animal tankage 5%, pluck powder 13%, oyster shell whiting 2%, described percentage is weight percentage.

Described feed making method is: get above-mentioned substance abundant pulverizing the respectively according to described than row; sieve with 80 eye mesh screens; the dish leaf breaks into dish liquid slurry; described material powder and dish liquid slurry are put into the fish feed mixer jointly and were stirred 50 minutes; make pellet with special fish meal ring modeling pelletizer again; 2 millimeters of feed particle diameters, feed dry the back bag distribution packaging and get final product.

Beneficial effect: the present invention selects for use multiple feedstuff assembly to form, and provides the feed basis for producing river snail, animal protein and vegetable protein reasonable mixture ratio in the composition, and nutritional labeling is abundant, is conducive to river snail digesting and assimilating various nutritional labelings; The feed of this formulated, raw material are easy to get, good palatability, easily digestion, absorb soon, and river snail fast growth, resistance against diseases be strong, culture the survival rate height.
