Abstract
The present invention provides a formula of an eriocheir sinensis ecology starter feed. The formula is characterized by comprising the following substances, by weight: 22-31% of soybean meal, 24-33% of fish powder, 1-3% of rotifer powder, 1.5-3.5% of cuttlefish powder or a cuttlefish paste, 5-12% of fermentation cottonseed protein, 2.5-7.5% of defatted rapeseed meal, 2-4% of soybean phospholipid powder, 1.5-3% of silkworm pupa powder, 1-1.5% of soybean oil, 1-3% of fish oil, 1.8-2.5% of calcium dihydrogen phosphate, 15-20% of wheat flour, 0.05-0.15% of shelling powder, 0.5-1.5% of a crab trace element additive, 0.1-0.3% of a crab composite vitamin, and 0.1-0.3% of 50% choline chloride. According to the present invention, the rotifer powder prepared from rotifer with characteristics of wide distribution, easy collection and high nutrition is added to the traditional eriocheir sinensis ecology starter feed, such that problems that nutrients of the traditional eriocheir sinensis ecology starter feed are single and nutritional values of the rotifer in the natural environment is not effectively utilized are solved.
Description
[0001] technical field [0002] The invention relates to the technical field of aquaculture feed, in particular to a formulation of an ecological opening feed for river crabs and a preparation method thereof. Background technique [0003] Rotifer powder is a collective name for nearly 2,000 tiny invertebrates of the Aschelminthes class Rotifera (Rotifera or Rotaria). Complete composition, relatively high crude fat content, rotifers are widely distributed in lakes, ponds, rivers, coastal waters and other fresh and salt water bodies, even in wet soil sites and mosses, rotifers are extremely fast The reproduction rate is high, and the production volume is very high, which is of great significance in the study of ecosystem structure, function and biological productivity. Rotifers are the opening bait for most economical aquatic animal larvae, and have considerable application value in fishery production. However, in the traditional aquaculture industry, especially the opening f...
