Special feed for factory-like circulating water short-term grass carp breeding and preparation method

[0016] A kind of preparation method of special feed for short-term cultured grass carp with industrial circulating water, the specific steps of the method are:

[0017] (a) First, crush inosinic acid, L-carnitine, vitamin E, astaxanthin, and rice through a 100-mesh sieve;

[0018] (b) Next, mix the pulverized inosinic acid, L-carnitine, vitamin E, astaxanthin, and rice flour in proportion to form a solid raw material;

[0019] (c) Finally, the conjugated linoleic acid is uniformly added to the mixed solid raw material in proportion to obtain the feed.

[0021] First, inosinic acid 10g, L-carnitine 50g, vitamin E 25g, astaxanthin 10g, rice flour 630g. Crushed through a 100-mesh sieve; secondly, the pulverized inosinic acid, L-carnitine, vitamin E, astaxanthin, and rice flour were mixed evenly to form a solid raw material; finally, 50 parts of conjugated linoleic acid were evenly added to the mixed Among the solid raw materials, a special feed for short-term grass carp breeding in industrialized circulating water is formed.

[0023] First, add 50g of inosinic acid, 15g of L-carnitine, 75g of vitamin E, 30g of astaxanthin, and 790g of rice flour. Crushed through a 100-mesh sieve; secondly, the pulverized inosinic acid, L-carnitine, vitamin E, astaxanthin, and rice flour were evenly mixed to form a solid raw material; finally, 200g of conjugated linoleic acid was evenly added to the mixed solid Among the raw materials, a special feed for short-term grass carp breeding in industrialized circulating water is formed.

[0024] In order to verify the effect of the special feed for grass carp breeding in industrialized circulating water for a short period of time in the present invention, two kinds of feeds, feed A and feed B, are used. Special feed for grass carp farming.
