Anti-stress puffed feed for black carps and production method thereof

Abstract

The invention relates to an anti-stress puffed feed for black carps and a production method thereof and belongs to the technical field of aquatic product compound feed. The production method thereof is characterized by comprising the following steps: crushing fish meal, bean pulp, silkworm pupa, corn protein feed, rapeseed meal, cotton meal, blood powder, bread flour and potassium sorbate mildewcide, and uniformly mixing the crushed mixture and fish oil, 50 percent choline chloride, rhubarb anthraquinone extract, immune polysaccharide, lactobacillus sporogenes, premix compound for fish, zeolite and calcium biphosphate with stirring; crushing the mixture to form a mixed material with a supermicronmill after uniformly mixing with stirring, adding the mixed material into a modulator, introducing water vapor into the modulator to modulate the mixed material, and adding the modulated mixed material into an extruding and puffing granulator to prepare the mixed material into particles; and drying and cooling the puffed feed particles and packing the feed particles into bags. The anti-stress puffed feed of the invention has simple preparation and balanced and rich nutrition, can meet the growing requirements of the black carps, improves the immunity and oxidation resistance of the black carps, improves the anti-stress property and disease resistance, reduces water body pollution caused by throwing the feed in a breeding process, improves the palatability of the feed and promotes growth.

Description

technical field [0001] The invention relates to an anti-stress extruded herring feed and a production method thereof, belonging to the technical field of aquatic compound feed. Background technique [0002] Herring belongs to Cyprinidae, Cyprinidae, Yaluo subfamily, and Herring. Commonly known as: black carp, green carp, snail green. The herring body is long, slightly cylindrical, with flattened tail, round abdomen, and no ventral rib. The head is slightly flattened and the tail is flattened sideways. The mouth end is arc-shaped. Upper jaw slightly longer than lower jaw. Dorsal and anal fins without spines, dorsal and pelvic fins opposite. The back and upper part of body sides are blue-black, the abdomen is gray-white, and the fins are gray-black. It is mainly distributed in the plain area south of the Yangtze River in my country, and it is rare in the north of the Yangtze River. It is an important fishery resource in the middle and lower reaches of the Yangtze River a...

Problems solved by technology

[0004] However, in aquaculture, in order to pursue high benefits, under intensive and high-density farming, the water body is easily polluted, especially under high temperature conditions, diseases occur frequently, and in practice, it is easy to bleed, and the fish body turns red, which affects the economy of pombra. Benefits have brought huge economic losses to the breeding industry. In order to prevent and control pathogenic bacteria, antibiotics and antibacterial drugs have been used in large quantities, and cause drug residues, enhanced drug resistance, decreased animal immunity, microecological disorders, and teratogenic, carcinogenic, A series of adverse consequences such as environmental pollution, some antibiotics or antibacterial drugs, there will be drug residues, affecting human food safety and the sustainable development of aquaculture
