Abstract

The present invention relates to procambarus clarkii special fat powder, and a preparation method and an application thereof. The procambarus clarkii special fat powder comprises the following components in parts by weight: 10-30 parts of compound omega-3 functional fatty acid ester, 5-20 parts of a yeast extract and 30-65 parts of a carrier. A mixture of the compound omega-3 functional fatty acidester, yeast extract and carrier at the specific weight ratio is used as the procambarus clarkii special fat powder to be added into a basic feed, and a nutritional intake method is used to improve immunity of procambarus clarkii, improves growth performance of the procambarus clarkii, saves resources, protects water quality, and improves economic efficiency. In addition, the feed added with thefat powder has stable properties and is not prone to rancidity, bitterness and reduced nutritional value during processing and storage processes.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a crayfish feed additive and its preparation method and application, in particular to a crayfish special fat powder and its preparation method and application. 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 the crayfish can the rapid growth of the crayfish be promoted. However, crayfish need to molt about 11 times from birth to sexual maturity, and each moult is a stress and a large amount of energy consumption, which will easily lead 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] Fat in feed provides esse...
