Feed for promoting fish muscle growth by using S-adenosylmethionine as well as preparation method and application of feed

Abstract

The invention discloses a feed for promoting fish muscle growth by using S-adenosylmethionine and a preparation method of the feed. Comprising the following components: 5 to 10 parts of fish meal, 10 to 20 parts of chicken meal, 20 to 30 parts of soybean protein isolate, 5 to 10 parts of cottonseed protein, 2.5 to 2.8 parts of fish oil, 1.8 to 1.3 parts of soybean oil, 1.0 to 1.5 parts of soybean lecithin, 1 to 2 parts of squid paste, 0.5 to 1.5 parts of monocalcium phosphate, 0.3 to 0.6 part of composite vitamin, 0.2 to 0.4 part of composite mineral substance, 2 to 5 parts of amino acid mixture and 0.1 to 2.5 parts of S-adenosylmethionine. The invention also discloses a preparation method of the feed and application of the feed in preparation of fish daily ration. The feed disclosed by the invention improves the absorption and transfer efficiency, improves the nutrition physiology of the largemouth bass, promotes nutrient substance metabolism of the largemouth bass, remarkably increases the number of muscle fibers, reduces the cross sectional area of the muscle fibers, efficiently promotes muscle growth, increases the content of protein in muscles, and reduces the discharge amount of nitrogen and phosphorus in the feed.

Description

technical field [0001] The invention relates to the field of nutritional feeds, and more particularly, to a feed for promoting fish muscle growth by using S-adenosylmethionine, a preparation method and applications thereof. [0002] technical background [0003] Largemouth bass (Micropterus salmoides) is an important aquaculture economic fish in my country. The aquaculture output will exceed 600,000 tons in 2020. It is currently the freshwater fish with the largest annual output growth rate in my country, and has made outstanding contributions to the increase of aquaculture industry revenue. In recent years, although researchers have carried out a series of nutritional research work on the development of its compound feed, the replacement of fishmeal in the feed leads to a decrease in muscle deposition, which affects growth performance and is still a bottleneck restricting the development of largemouth bass aquaculture industry. Therefore, there is an urgent need for a feed a...

Problems solved by technology

In recent years, although researchers have carried out a series of nutritional research work on the development of its compound feed, however, the substitution of fishmeal in the feed leads to a decrease in muscle deposition, which in turn affects growth performance and is still a bottleneck restricting the development of the largemouth bass aquaculture industry.
