Prochilodus scrofa mixed feed and preparation method thereof

Abstract

The invention relates to prochilodus scrofa mixed feed, and further relates to a preparation method of the prochilodus scrofa mixed feed. The prochilodus scrofa mixed feed provided by the invention is prepared from the following components in parts by mass: 21 to 29 parts of fish meal, 5 to 15 parts of vegetable cake, 4 to 15 parts of sweet potato flour, 5 to 14 parts of fructus quisqualis, 6 to 17 parts of pumpkin seed, 3 to 11 parts of Chinese torreya seed, 5 to 16 parts of semen raphani, 5 to 14 parts of fructus lycii, 3 to 10 parts of ferula asafoetida, 4 to 15 parts of sweet potato leaves, 3 to 15 parts of elm seeds, 3 to 10 parts of medicated leaven, 5 to 14 parts of folium perillae, 3 to 9 parts of fish oil, 1 to 4 parts of olive oil and 1 to 4 parts of compound vitamin, after the prochilodus scrofa mixed feed is fed, the prochilodus scrofa mixed feed coefficient is low, the crude protein content of the muscle of prochilodus scrofa is high, the crude fat content is low and the flavor amino acid content is high.

Description

technical field [0001] The invention relates to a fish feed, in particular to a South American herring compound feed; the invention also relates to a preparation method of the South American herring compound feed.

Problems solved by technology

In addition, the quality of artificially farmed South American herring is worse than that of wild South American herring, which is mainly manifested in: the lean meat rate of artificially farmed South American herring is low, the crude protein content in muscle is low, and the crude fat content is higher than that of wild South American herring

Muscle quality is an important economic trait of farmed animals. At present, the poor quality of artificially farmed fish has become a major problem affecting its commodity prices and sustainable development
