Special feed for flounder fries and processing method of special feed

Abstract

The invention relates to a special feed for flounder fries and a processing method of the special feed, and belongs to the technical field of processing of aquaculture feeds. The special feed is prepared from the following raw materials in parts by weight: 30-50 parts of fish meal, 10-25 parts of wheat flour, 10-15 parts of yeast powder, 5-8 parts of fish oil, 0.1-0.3 part of choline chloride, 0.2-0.6 part of lysine, 0.2-0.5 part of methionine, 0.3-0.6 part of thetine, 0.1-0.5 part of protease, 0.2-0.5 part of lipidase, 0.8-3 parts of complex vitamins, and 1.0-3.0 parts of composite mineral substances. In accordance with the growth characteristics of flounder, according to the formula of the special feed disclosed by the invention, the nutrition in the feed can meet the growth requirements of the flounder fries, the lysine and the methionine are added, so that the utilization rate of zymolyte of vegetable protein is increased, the absorption of nutrients is promoted, and the digestibility of raw materials is improved; besides, the taste is strengthened, the feeding habit of the flounder fries is met, the feed coefficient of the feed is low, and the specific growth rate is high.

Description

technical field [0001] The invention relates to a special feed for flatfish fry and a processing method thereof, belonging to the technical field of aquaculture feed processing. Background technique [0002] Flounder is an important part of marine fish cultured in China. Its meat is delicious and tender, rich in nutrition, and has extremely high nutritional and economic value. It is distributed along the coast of China and is the main species for the development of marine aquaculture. The cultivation of flounder seedlings is directly related to the quality of fry. Artificially cultivating seedlings with strong physique, strong disease resistance and fast growth can greatly improve the quality of adult fish farming. The success rate of the flounder seedlings, and the nutrition provided to the flounder flounder seedlings directly affects the growth of the flounder flounder seedlings. At present, there is a lack of special feed for flounder flounder seedlings on the market. C...
