Anti-stress expanded feed for Erythroculter ilishaeformis Bleeker and production method thereof

Abstract

The invention relates to anti-stress expanded feed for Erythroculter ilishaeformis Bleeker and a manufacturing method thereof. The manufacturing method is characterized by comprising the following steps: firstly grinding fish meal, bean pulp, silkworm pupa, expanded soybeans, rapeseed meal, cottonseed meal, peanut meal, bran, wheat middling, squid extract and potassium sorbate mildew preventive; stirring and blending evenly with fish oil, vegetable oil, lecithin, 50% of choline chloride, rhubarb anthraquinones extractive, glutamine dipeptide, premix for fish, zeolite and monocalcium phosphate; grinding into mixed materials by an ultrafine grinding machine after stirring and blending evenly; moving the mixed material into a modulator and introducing water vapor for modulation; entering an extrusion pelleter to manufacture into feed particles after modulation; packaging the expanded feed particles after drying and cooling. The invention has simple preparation, balanced and rich nutrition, can satisfy the growth requirement of Erythroculter ilishaeformis Bleeker, improve fish body immunity and oxidation resistance, improve anti-stress and disease-resistant capabilities, reduce water body pollution caused by feed casting in the culturing process, improve feed palatability and promote growth.

Description

technical field [0001] The invention relates to an anti-stress puffed feed for red carp and a production method thereof, and belongs to the technical field of aquatic compound feed. Background technique [0002] Erythroculter ilishaeformis Bleeker belongs to Cypriniformes, Cyprinidae, Cultrinae, and Erythroculter Berg. , Heshun, and Taihu Lake whitefish are one of the well-known "Three Whites of Taihu Lake". It is large in size, fast in growth, white in texture, tender and delicious in taste, and high in amino acid content. It is a top-grade fish and is deeply loved by the masses. . The cocked-billed red bream is a large-scale freshwater economic fish in the middle and upper layers. It moves swiftly, is good at jumping, has a violent temper, and is easily frightened. Red carp is a euthermic fish, with a living water temperature of 0-38°C, a feeding water temperature of 3-36°C, an optimum water temperature of 15-32°C, an optimum growth water temperature of 18-30°C, and a br...

AI Technical Summary

Problems solved by technology

[0003] However, at present, the nutritional requirements of the artificial compound feed of the red crocodile are borrowed from other fish. There are relatively few studies on the nutritional requirements, and there are a few reports on the requirements of protein and fat. Metabolic studies are rarely reported

In the actual breeding process, it is also found that the red cymbal is quite irritable. If there are some slight noises from the outside world, the fish will have a great stress response, and it is easy to jump, causing the scales to fall off easily and die.
