Abstract

The invention relates to a special fat powder for crayfish and a preparation method and application thereof. The special fat powder for crayfish comprises, in parts by weight: 10-30 parts of composite omega-3 functional fatty acid ester and 5-20 parts of yeast extract and carrier 30‑65 copies. In the invention, the compound omega 3 functional fatty acid ester, yeast extract and carrier in a specific weight ratio are mixed as a special fat powder for crayfish and added to the basic feed, so as to enhance the immunity of crayfish and improve the growth of crayfish by means of nutrient intake. performance, save resources, protect water quality, and improve economic benefits. In addition, the feed added with the fat powder has stable properties, is less prone to oil rancidity, and is less prone to bitterness and reduced nutritional value during processing and storage.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, in particular to a crayfish feed additive and a preparation method and application thereof, in particular to a special fat powder for crayfish and a preparation method and application thereof. Background technique [0002] The survival rate of crayfish is the most critical link in the breeding process, which determines the production efficiency of crayfish and directly affects the economic benefits of farmers. Only by ensuring the health of crayfish can we promote the rapid growth of crayfish. However, crayfish need to molt about 11 times from birth to sexual maturity, and each molting is a stress and a lot of physical energy consumption, which easily leads to a decrease in disease resistance and stress resistance, and a decrease in feed intake. , Low digestibility of exogenous nutrients, atrophy and degeneration of intestinal villi, and slow growth. [0003] In addition to providing energy...
