High-absorption environment-friendly puffed sinking compound feed for crayfishes and preparation process thereof

Abstract

The invention discloses a high-absorption environment-friendly puffed sinking compound feed for crayfishes and a preparation process thereof. The formula of the feed comprises the raw materials of, byweight, 3 to 8 parts of vegetable protein powder, 35 to 45 parts of soybean meal, 25 to 35 parts of rapeseed meal, 5 to 12 parts of high-gluten flour, 2 to 6 parts of fish oil, 1 to 3 parts of composite vitamins, 1 to 3 parts of trace elements and 0.5 to 1.5 parts of phagostimulant. The preparation process of the feed comprises the steps of mixing the vegetable protein powder, the soybean meal, the rapeseed meal and the high-gluten flour, carrying out secondary crushing treatment, adding the phagostimulant by stages, then adding the trace elements and the composite vitamins to prepare a sinking puffed material, and finally drying, spraying oil, cooling and sieving to obtain a finished product. The feed and the preparation process have the characteristics of improving the culture yield andthe culture health level, reducing the feed cost, improving the feed utilization rate and reducing the water body pollution.

Description

technical field [0001] The invention relates to a crayfish feed, in particular to a crayfish high-absorption and environment-friendly puffed sinking compound feed and a preparation process thereof. Background technique [0002] Crayfish, commonly known as crayfish, belongs to the class Crustacea, subclass Molecula, decapod order, suborder Reptiles, family Crayfish, and the genus Procambarus. Because it is similar to the lobster in the deep sea and the individual is small, it is often called "crayfish". Crawfish has the characteristics of strong adaptability, high reproduction rate, fast growth, etc., and the meat is tender, delicious, nutritious, rich in trace elements such as calcium, phosphorus, iron, zinc, iodine and selenium, and is popular among consumers. It is favored by investors and has huge potential in the international market. It is an excellent variety for my country's export to earn foreign exchange. In recent years, the natural resources of crayfish have decr...

AI Technical Summary

Problems solved by technology

The existing traditional crayfish breeding is often based on natural bait, which is properly mixed with corn, wheat, bean cake, bran and other single feeds or processed into paste feeds, resulting in unbalanced nutrient intake of crayfish in the breeding process , lead to problems such as slow growth of shrimp body, low disease resistance and deterioration of water quality, which seriously affect and restrict the large-scale and healthy farming of crayfish in my country; or add various high-nutrient ingredients to the feed, and the ratio is not very good Reasonable, the absorption rate of crayfish is not high, and the cost of feed is greatly increased, and the pollution of water is also serious

Therefore, the existing crayfish traditional feed has the problems of low shrimp body cultivation output and low health level, and the existing crayfish high-nutrition feed has high feed cost, low feed utilization rate, and relatively high water pollution. serious problem
