Black carp feed for eliminating anti-nutritional factors and preparation method of feed

Abstract

The invention discloses black carp feed for eliminating anti-nutritional factors and a preparation method of the feed. The feed is prepared from raw materials as follows: fresh clam meat, swine blood meal, rapeseed dregs, distiller's grains, loofah sponges, pomegranate seeds, Lagochilus leiacanthus, coix seed oil, phosphatide oil, zeolite powder, table salt, an antioxidant, allicin, a microecological preparation and compound premix. Compared with the prior art, the feed has the advantages as follows: the microecological preparation is added after the Lagochilus leiacanthus is used for acid regulation, the distiller's grains and the rapeseed dregs are fermented, glucosinolates and toxic substances can be effectively eliminated, then the feed cost is reduced, and the feed is high in utilization rate, contains richer digestible crude protein and can balance nutrition required by growth of black carp, so that the black carp grows rapidly and is high in disease resistance.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a herring feed for eliminating anti-nutritional factors and a preparation method thereof. Background technique [0002] Herring is a fish with a green color, mainly distributed in the plains south of the Yangtze River in my country, and relatively rare in the north of the Yangtze River; it is an important fishery resource in the middle and lower reaches of the Yangtze River and lakes along the river and the main breeding object in lakes and ponds , is one of the "four major fish" in freshwater farming in my country. Therefore, there is a large demand for herring farming in my country. Among them, the main method of fish farming in pond farming, and limited bait resources have affected the development of herring farming. Therefore, artificial feed is required. As a supplement, the protein content in the feed needs to reach 28-41% to meet its nutritional needs. If a l...

[0002] Herring is a fish with a green color, mainly distributed in the plains south of the Yangtze River in my country, and relatively rare in the north of the Yangtze River; it is an important fishery resource in the middle and lower reaches of the Yangtze River and lakes along the river and the main breeding object in lakes and ponds , is one of the "four major fish" in freshwater farming in my country. Therefore, there is a large demand for herring farming in my country. Among them, the main method of fish farming in pond farming, and limited bait resources have affected the development of herring farming. Therefore, artificial feed is required As a supplement, the protein content in the feed needs to reach 28-41% to meet its nutritional needs. If a large amount of meat feed is used, although the protein demand can be met, the cost will also increase greatly, and the quality of herring is not too high. Therefore, it will seriously affect the economic value. The protein content of rapeseed meal is high, but it contains anti-nutritional factors such as glucosinolates. If it is used too much, it will affect the growth of herring. Feeds that will contain more anti-nutritional factors
