Abstract

The invention provides a loach puffed feed and a preparation method thereof, and relates to the field of aquaculture. The loach puffed feed is prepared through the following steps of mixing an animal feed with a vegetable feed and auxiliary materials, performing puffing granulation, then performing spraying with an enveloping agent, and performing drying, wherein the animal feed comprises fish meal, silkworm chrysalis meal and corbicula fluminea meal; the vegetable feed comprises soybean meal, tea grounds and potato powder; and the auxiliary materials comprise an immunization additive, calcium dihydrogen phosphate, choline chloride, oligosaccharide, vitamins and minerals. According to the loach puffed feed disclosed by the invention, the health of intestinal tracts of loaches is effectively improved, the immunocompetence of the loaches is effectively improved, the disease resistance of the loaches is improved, the feed digestibility is improved, and the growing performance is improved. The invention further provides a processing method of the loach puffed feed. The operation method is controllable, and the utilization of the feed is effectively increased.

Description

technical field [0001] The invention relates to the field of aquaculture, and in particular to an extruded loach feed and a preparation method thereof. Background technique [0002] Loach belongs to Cyprinidae Cyprinidae and is omnivorous. Because of its tender meat and delicious taste, it is known as "ginseng in water". Consumers in South Korea and Japan are especially fond of it. 95% of domestically farmed loach are exported to South Korea and Japan, and the sales price is relatively high. , good profitability, and also gave birth to a new industry such as loach farming. However, there are great differences in feed efficiency and survival rate in loach farming at present. The reasons for the analysis are not only the loach species and seed quality factors, but also the weak anti-stress ability of feed and loach. [0003] Loach has a small mouth, short and straight intestines, and the ratio of the length of the intestines to the body length is only about 0.8, which is far ...
