Problems solved by technology

Its shortcoming is that this formula is more suitable for the nutritional needs of Scylla serrata larvae, but not suitable for the nutritional needs of the growth stage of Scylla serrata; lack of food attractant, the effect of attracting food for Scylla serrata is poor, and the feed residue is wasted ;The compound feed lacks shelling element, which is not conducive to the smooth shelling of the blue crabs, and it is easy to cause the death of the blue crabs; the organic matter such as fish paste and oil is easily corrupted in the compound feed, and at the same time lacks the necessary preservatives, the feed is easy to spoil and deteriorate. It is easy to get intestinal diseases, causing a large number of crabs to die

Abstract

The invention relates to a compound feed for Scylla serrata, a preparation method, and an application method thereof. The compound feed comprises a solid part and a liquid part, wherein the solid part is composed of fish meal, strong flour, soybean meal, peanut meal, beer yeast, fish oil, shrimp shell powder, cuttlefish paste, phospholipids, plasma protein powder, choline chloride, compound vitamins, compound mineral substances, a decladding element, sodium diacetate, betaine, butylated hydroxyanisole, phytase and beta-carotene. The preparation method of the invention comprises the steps of raw material smashing and sifting, mixing, conditioning, granulating, drying and packaging, ant the like. The feed prepared by the method of the invention has the advantages of good food calling effect, good palatability, high feed utilization, rich and overall nutrient, a raised feed utilizing rate of the Scylla serrata, reduced pool pollution, and significant environmental protection effect.

Description

technical field [0001] The invention relates to the field of feed for aquatic animal breeding, in particular to a compound feed for Scylla serrata, a preparation method and a use method. Background technique [0002] Scylla serrata ( Scylla serrata ), belonging to Crustacea, Malacostraca, Decapoda, and Portunidae, is an important economic mariculture crab in southeastern my country, with huge economic value and development potential. With the breakthrough of artificial breeding technology of mud crabs, the improvement of breeding technology and the development of various crab production models, the mud crab farming industry has developed vigorously, the scale of farming has continued to expand, and the output has continued to increase. The development prospects of mud crab farming are broad. . The formation and sustainable development of the blue crab industry must take the road of healthy breeding, and the key to healthy breeding is to supply high-quality seed and maintai...
