Megalobrama amblycephala anti-stress feed and production method thereof

Abstract

The invention relates to a megalobrama amblycephala anti-stress feed and a production method thereof. The preparation method is characterized by comprising the following steps of: crushing fish meal, bean pulp, silkworm pupa, rapeseed meal, rapeseed, cottonseed meal, all-purpose flour, sub-powder, washed rice bran, and potassium sorbate mildew preventive; stirring and uniformly mixing the crushed product and fish oil, lecithin, 50 percent choline chloride, rhubarb anthraquinone extract, premix for fish, attapulgite, 35 percent phosphate vitamin C, 50 percent vitamin E and monocalcium phosphate; after stirring and uniformly mixing, grinding the mixture into mixed materials by using an ultra-micro grinder; and preparing the materials into a pellet feed by using the conventional method of the pellet feed. The pellet feed has total and rich nutrition, and can improve the immunity and oxidation resistance of the megalobrama amblycephala, improve the stress, enhance the resistance to disease, improve the feed palatability, and accelerate the growth.

Description

Technical field [0001] The invention relates to an anti-stress feed for bream bream and a production method thereof, and belongs to the technical field of aquatic compound feed. Background technique [0002] Megalobrama amblycephala (Megalobrama amblycephala), belongs to the class of bony fishes, Cypriniformes, Cyprinidae, Subfamily Bream, and Bream. It is now one of the main freshwater cultured species in my country. Primary freshwater fish inhabit the middle and lower water layers of rivers, reservoirs, and lakes. They prefer silt bottoms and static areas with lush aquatic plants. It usually inhabits the middle and lower layers of open water areas where the bottom is silt and submerged plants grow. Juvenile fish mainly feed on cladocerans and other crustaceans; adult fish feed on aquatic plants, mainly bitter weeds and hydrangea verticillata, as well as a small amount of zooplankton. Tuantou bream grows fast and is omnivorous. The juvenile fish are mainly crustaceans, and the...

AI Technical Summary

Problems solved by technology

[0003] At present, there are many reports on the nutritional requirements of bream such as protein, amino acids, carbohydrates, fats, and trace elements. There are also related feed formulas in production, but in aquaculture, in order to pursue high benefits, intensive, high-density Under the conditions of high temperature and high temperature, diseases frequently occur. In practice, the pomace is easy to bleed, and the fish body turns red and yellow, which seriously affects the economic benefits of pomace and brings huge economic losses to the aquaculture industry. Pathogens, antibiotics and antibacterial drugs have been used in large quantities, and have caused a series of adverse consequences such as drug residues, enhanced drug resistance, decreased animal immunity, microecological disorders, teratogenicity, carcinogenicity, and environmental pollution. Some antibiotics or antibacterial drugs, There will also be drug residues, affecting human food safety and the sustainable development of aquaculture

[0004] The feed formula for pomace bream described in previous patents mainly considers comprehensive and reasonable nutrition, and is mainly aimed at the cultivation of ponds, but with economical and high-density cultivation, diseases and deaths are often prone to occur
