Abstract

The invention discloses mixed feed for cultivating soft-shell scylla serrata. The mixed feed is prepared from the following components in parts by weight: 35-40 parts of fish meal, 10-15 parts of blood meal, 5-10 parts of shrimp head meal, 20-25 parts of puffed soybean meal, 10-15 parts of peanut meal, 3-5 parts of beer yeasts, 5-10 parts of wheat germ powder, 3-5 parts of fish oil, 3-5 parts of vital gluten, 5-10 parts of rosemary powder, 1-3 parts of calcium dihydrogenphosphate, 0.1-0.2 part of unshelling elements, 0.01-0.03 part of butyl hydroxy anisd, 0.01-0.03 part of butylated hydroxytoluene, 1-3 parts of a weighting agent, 1-3 parts of compound phagostimulant, 0.3-0.5 part of multi-vitamin additives and 0.1-0.3 part of compound mineral additives. The mixed feed disclosed by the invention can promote the scylla serrata to unshell to improve the survival rate and shorten the cultivating period of the soft-shell scylla serrata. The survival rate of the soft-shell scylla serrata is high and the weight gain rate is great, so that the culture benefit is improved. The invention further discloses a preparation method of the mixed feed for cultivating the soft-shell scylla serrata. The preparation method is simple in process step and suitable for industrialized production, and the prepared mixed feed is less in nutritional loss, good in moldability and uniform in granule.

Description

technical field [0001] The invention relates to the technical field of compound feed, in particular to a compound feed for cultivating soft-shell mud crabs and a preparation method thereof. [0002] Background technique [0003] Scylla serrata, referred to as blue crab, has the characteristics of fast growth, large individual, strong adaptability and disease resistance, easy transportation, delicious meat, rich nutrition, and good breeding benefits. It is very popular among domestic and foreign producers and consumers. Favored, it is one of the important marine economic farming crabs in my country. [0004] Soft-shell Scylla serrata refers to the freshly shelled Scylla serrata. The soft-shell Scylla serrata does not need to be peeled when eating, but can be eaten with the shell, which is more convenient and hygienic to eat. It not only retains the flavor of the original crab, And more nutrients. The current soft-shell mud crab is favored by consumers at home and abroad, an...
