Feed for Leiocassis longirostris in fattening period

Abstract

The invention discloses a feed for Leiocassis longirostris in the fattening period. Raw materials of the feed comprise 30-50 parts of fermented grape seed meal, 20-40 parts of fermented sunflower seed meal, 5-10 parts of peanut meal, 2-10 parts of fish meal, 2-5 parts of honey, 1-2 parts of egg white, 4-12 parts of phoenix eggs, 1-4 parts of kelp powder, 1-2 parts of Herb of Hairystalk Loosestrife, 4-8 parts of an antibacterial system, 8-12 parts of a granulation system, 0.15-0.35 parts of fructooligosaccharides, 0.1-0.6 parts of nicotinamide and 0.01-0.04 parts of EM bacteria. A corn flour compound is prepared through the following steps: stirring corn flour, hydroxypropyl guar gum and an ethanol solution, adding 2-chloroethyldiethylamine, stirring above substances, filtering the stirred substances, drying the filtered substances until the weight is constant, and crushing the dried substances. The feed has the advantages of easily available raw materials, low cost, richness in nutrients, good dispersibility, easiness in digestion and absorption by the Leiocassis longirostris, effective reduction of the mortality rate of the Leiocassis longirostris, difficulty in dissolving of a bait in water, and facilitation of a water environment.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a feed for catfish in the fattening period.
