Compound feed capable of quickly recovering body color of blue-body penaeus monodon and preparation method of compound feed

Abstract

The invention discloses a compound feed capable of quickly recovering body color of blue-body penaeus monodon. The compound feed comprises the following components in parts by weight of 30-45 parts offish meal, 3-6 parts of chicken meat powder, 17-20 parts of soybean meal, 3-10 parts of peanut cakes, 17-20 parts of low-gluten flour, 1-3 parts of shrimp paste, 1-3 parts of squid paste, 2-5 parts of soybean phospholipid oil, 5-10 parts of crayfish powder, 5-10 parts of euphausia superba powder, 0.2-0.4 part of xanthophyll, 1-2 parts of bentonite and 1-2 parts of a mixture of multiple vitamins and multiple minerals. The compound feed further comprises the following components of 0.2-0.5 part of choline chloride, 0.2-0.5 part of sodium chloride, 1-2 parts of calcium bis(dihydrogenphosphate),0.01-0.03 part of an antioxidant and 0.05-0.1 part of a feed mildewproof agent. The compound feed disclosed by the invention has good color mixing effects, can replace a compound feed with astaxanthin, can quickly recover the body color of the blue-body penaeus monodon, is low in cost and can effectively increase breeding benefits. The invention further provides a preparation method of the compound feed. The preparation method is simple, and large-scale production is convenient to realize.

Description

technical field [0001] The invention relates to the technical field of prawn feed manufacturing, in particular to a compound feed capable of quickly restoring the body color of Penaeus monodon and a preparation method thereof. Background technique [0002] Penaeus monodon, commonly known as king prawn and grass shrimp in China, has high economic value, and the scale of farming has gradually risen. It has become the main species to replace Penaeus vannamei in summer. With the improvement of breeding technology, the stocking density is gradually increasing, and the yield per mu is also increasing; however, there will be blue body problems in the culture of Penaeus monodon, and with the increase of the breeding density, the blue body problem of Penaeus monodon will become more serious. According to the market survey, if the prawns are produced at 60 tails / catties, the price of blue-bodied P. monodon will be 5-6 yuan per kg less than that of normal P. monodon, which will serious...

AI Technical Summary

Problems solved by technology

In recent years, in order to solve the problem of the blue body of Penaeus monodon, some feed manufacturers have also introduced feeds that can quickly restore the body color of Penaeus monodon. The main ingredient of this feed is astaxanthin. The breeding experiments have also proved that shrimp The effect of blue-bodied Penaeus monodon on coloring, but due to the high price of astaxanthin, the cost of this kind of feed is too high, the cost of breeding increases, and the breeding benefits of Penaeus monodon are reduced
