Special puffed compound feed for leiocassis longirostris and preparation method thereof

Abstract

The invention discloses special puffed compound feed for leiocassis longirostris and a preparation method thereof. The feed is prepared from the following ingredients in parts by weight: 25 to 28 parts of fish meal, 10 to 15 parts of fish steak powder, 2 to 3 parts of spray-dried animal blood cells, 30 to 35 parts of bean pulp, 10 to 15 parts of rapeseed meal, 10 to 15 parts of high gluten flour,2 to 3 parts of bean oil, 4 to 5 parts of bentonite, 2 to 3 parts of mountain flour, 1 to 2 parts of monocalcium phosphate, 0.1 to 0.5 part of choline chloride, 0.1 to 0.5 part of mildew preventives,0.01 to 0.05 part of antioxidants and 0.1 to 0.3 part of premixed materials. All ingredients are mixed and are then crushed to 60 to 80 meshes; next, expansion and granulation are performed. The special puffed compound feed can meet the growth requirements of the leiocassis longirostris; the growth speed of the leiocassis longirostris is accelerated; the feed conversion efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of fish feed, and in particular relates to a special puffed compound feed for long-breasted catfish and a preparation method thereof. Background technique [0002] Leiocassis longirostris (Leiocassis longirostris) belongs to the Siluriformes, the family Oleuridae, and the genus, also known as catfish. It is called "Catfish" in Shanghai, "Jiangtuan" in Sichuan, and "Xiyu" in Guizhou.

AI Technical Summary

Problems solved by technology

[0004] However, due to the short artificial breeding time and the limited breeding area of ​​the long-snout catfish, there are few studies on its nutritional requirements, and the obtained experimental data are not very informative; Combining nutrition research with processing technology due to slowness and other characteristics, the pellets produced are often not the most suitable feed for long-snout catfish breeding
