Apostichopus japonicus Selenka feed by replacing sargassum thunbergii for terrestrial plants

Abstract

The invention discloses an Apostichopus japonicus Selenka feed by replacing sargassum thunbergii for terrestrial plants, which has low cost and high nutritional value and can obviously improve the special growth rate, amylase activity, digestibility and immunity of the Apostichopus japonicus Selenka. The Apostichopus japonicus Selenka feed consists of the following components in percentage by weight: 11 percent of fish meal, 7 percent of soybean protein, 40 percent of sea mud, 5 percent of shrimp, 1 percent of yeast, 0.2 percent of xanthan gum, 0.8 percent of mineral, 5 percent of shell powder, 3.75 percent of pumpkin starch, 3.75 percent of papaya starch, 3.75 percent of sweet potato starch, 3.75 percent of potato starch, 10 percent of taro starch, 2 percent of red date starch and 3 percent of yam starch, wherein the starch is powder which is prepared by pasting, drying, grinding and crushing.

Description

Technical field: [0001] The invention relates to an animal feed, especially a sea cucumber with low cost and high nutritional value, which can obviously improve the special growth rate, intestinal amylase activity, digestibility and immunity of sea cucumber, which uses terrestrial plants to replace sargassum feed. Background technique: [0002] Sea cucumber (Apostichopus japonicus Selenka) has extremely high nutritional and medicinal value, and is an important species of mariculture in northern my country. High-efficiency, cheap and safe feed is the material basis for the development of sea cucumber aquaculture. Contains about 30% Sargassum thunbergii, Sargassum sp or other macroalgae powder. Because the artificial breeding of large algae such as sargassum is still in the research stage, the sargassum currently used is all collected from the wild. With the continuous expansion of Apostichopus aquaculture, the consumption of sargassum and other algae is also increasing. Howe...

AI Technical Summary

Problems solved by technology

With the continuous expansion of Apostichopus aquaculture, the consumption of sargassum and other algae is also increasing. However, due to the serious pollution of offshore water and non-aquaculture applications along the coast, the growth and living space of sargassum is shrinking year by year, resulting in the production of large algae such as sargassum. The sharp drop, the shortage of supply, stimulated the rising prices of sargassum powder, etc., and the cost of sea cucumber cultivation continued to increase
