Embodiment 1

[0049] The compound feed additive of every 100 parts by weight contains 6 parts by weight of methionine chelated manganese, 2 parts by weight of methionine chelated copper, 30 parts by weight of berberine, 20 parts by weight of creatine and 0.5 parts by weight of red fife The ratio of yeast and defatted rice bran as the balance is mixed to obtain a compound feed additive for improving liver mitochondrial function of sea bass.

[0050] Among them, the ligand ratio of methionine chelated manganese is 2.5:1. Copper contained in methionine chelated copper is Cu 2+ , The chelation rate of copper in methionine chelated copper is 92%, and the ligand ratio of methionine chelated copper is 2:1.

Embodiment 2

[0052] The difference between the present embodiment and Example 1 is: the compound feed additive containing 10 parts by weight of methionine chelated manganese, 6 parts by weight of methionine chelated copper, 50 parts by weight of berberine, 30 parts by weight of compound feed additive per 100 parts by weight The creatine and 2 parts by weight of Phaffia rhodozyme and the balance of defatted rice bran are mixed with each raw material to obtain a compound feed additive for improving the liver mitochondrial function of sea bass.

Embodiment 3

[0054] The difference between the present embodiment and Example 1 is: the compound feed additive containing 7 parts by weight of methionine chelated manganese, 3 parts by weight of methionine chelated copper, 35 parts by weight of berberine, 23 parts by weight of compound feed additive per 100 parts by weight Creatine, 0.5 parts by weight of Phaffia rhodozyme, and the rest in the ratio of defatted rice bran are mixed to obtain a compound feed additive for improving liver mitochondrial function of sea bass.

Abstract

The invention relates to a composite feed additive capable of improving liver mitochondria function of jewfish as well as a preparation method and application of the composite feed additive, and belongs to the field of feeds. Each 100 parts by weight of the composite feed additive comprises the following components in parts by weight of 6-10 parts of manganese chelate methionine, 2-6 parts of copper chelate methionine, 30-50 parts of berberine, 20-30 parts of creatine, 0.5-2 parts of red Fife yeast and the balance of a carrier. The raw materials of the composite feed additive are safe, harmless, and free from residues, and create condition for production of green feeds and aquatic products. According to the preparation method of the composite feed additive, the raw materials are mixed in compounding ratio. The preparation method is simple, good in condition controllability, and good in stability, and has favorable application prospects. The composite feed additive is applied to preparation of the feed for jewfish, so that the liver mitochondria antioxidant ability and the mitochondrial respiratory chain function of the jewfish can be improved, and the mitochondria oxidative damagecan be reduced.

Description

technical field [0001] The invention relates to the field of feed, and in particular to a compound feed additive for improving liver mitochondrial function of sea bass, a preparation method and application thereof. Background technique [0002] In recent years, with the development of high-density, intensive, and industrialized aquaculture, the frequent occurrence of fatty liver in cultured sea bass is a common problem faced by the aquaculture industry. Fatty liver will not only reduce the growth rate and feed conversion rate of sea bass, but also reduce the immunity of sea bass, bring huge economic losses to sea bass farming, and seriously affect the healthy development of sea bass farming. According to the results of many years of research in our laboratory, it was found that the dysfunction of mitochondria is the root cause of fatty liver in sea bass. Mitochondrial dysfunction leads to reduced fatty acid decomposition energy, and fat is prone to excessive deposition in s...
