Problems solved by technology

[0003] At present, the vast majority of crab farmers in our country feed single feeds when breeding river crabs, such as corn, wheat, small miscellaneous fish, ice fresh fish, etc. In this way, the river crabs that are forced to eat a partial diet are unbalanced in nutrition, resulting in small adult crabs. The fat is not plump, and the growth of river crabs is also prone to diseases
The eating process of river crabs is relatively long, so it is necessary for river crab feed to maintain appropriate water resistance, so as to avoid the loss of river crab feed in the water, which will affect the feeding of river crabs and affect the economic benefits of artificial breeding of river crabs

Abstract

The present invention discloses a good water-resistant feed for river crabs. The good water-resistant feed is prepared from fish meal, soybean meal, rapeseed meal, wheat flour, wheat gluten, corn protein powder, food attracting powder, a zinc ion-porphyrin nanocomplex, beta-D-mannuronic acid, bamboo salt, pullulan, calcium dihydrogen phosphate, a membrane coating material, multivitamins and ferrous fumarate. The present invention also discloses a preparation method of the good water-resistant feed for the river crabs. The good water-resistant feed is stable in raw material source, the materials cooperate with each other, complementary functions between the nutrients are exerted, the good water-resistant feed has advantages of comprehensive nutrition, good water resistance, high feed utilization rate and good attracting property, significantly improves feed intake, digestibility, immunity and disease resistance of the river crabs, reduces use of antibiotics, promotes growth and development of the river crabs, and effectively improves economic benefits of river crab farming.

Description

technical field [0001] The invention belongs to the technical field of feed, and in particular relates to a feed with good water resistance for river crabs and a preparation method thereof. Background technique [0002] The scientific name of the river crab is "Chinese mitten crab". It often lives in caves on the mud banks of rivers, rivers, and lakes. It is nocturnal and feeds on fish, shrimp, animal carcasses, and grains. It often migrates to the estuary where it goes out to sea every autumn to lay eggs. River crab meat is fresh and tender, rich in nutrition, about 14g of protein, about 5.9g of fat, about 7.4g of carbohydrate, and about 0.71g of riboflavin in every 100g of edible part. Its nutritional value is higher than that of general aquatic products. It has the functions of strengthening tendons and bones, detoxifying knees, etc., and has good health care effects, and is deeply loved by consumers. Due to the large market demand for river crabs, wild river crabs canno...
