Anti-stress and puffed mixed feed for ctenopharyngodon idellus and production method for feed

Abstract

The invention relates to anti-stress and puffed mixed feed for ctenopharyngodon idellus and a production method for the feed. The mixed feed includes the following raw materials in mass percentage: 0-8% of meat and bone meal, 2-5% of broad bean albumen powder, 8-18% of soybean meal, 20-30% of rapeseed dregs, 10-15% of cottonseed meal, 10-20% of wheat, 10-20% of tapioca flour, 5-8% of rice bran, 2-4% of soya-bean oil, 0.2-0.4% of 50% choline chloride, 0.9-1.5% of monocalcium phosphate, 1-2% of vitamin premix, 1-2% of mineral premix, 1-2% of zeolite powder, 0.02-0.1% of GSH, 0.01-0.08% curcumin, 0.01-0.03% of tea polyphenol, 0.05-0.1% of taurine, 0.005-0.01% of rheum emodin, 0.01-0.02% of L-carnitine, and 0.02-0.03% of complex enzyme preparation. The anti-stress and puffed mixed feed improves the digestibility and deposition of feeding ctenopharyngodon idellus to nutrient substances of the feed, improves the immune, antioxidant and anti-stress ability of fish body and promotes growing of ctenopharyngodon idellus.

Description

technical field [0001] The invention relates to an aquatic compound feed and a production method thereof, in particular to a grass carp anti-stress puffed compound feed and a production method thereof. Background technique [0002] Grass carp (Ctenopharyngodon idellus) belongs to Osteopharyngodon idellus, Cyprinidae, Cyprinidae, Yaluo fish subfamily, Grass carp genus, commonly known as grass carp, grass carp, oil carp, white carp, grass root (Northeast), mixed child, etc. It is one of the "four major fish" in traditional freshwater farming. Grass carp generally likes to inhabit the middle and lower layers of rivers, lakes and other waters and areas with many aquatic plants near the shore. They often forage in groups and are typical herbivorous fish. Grass carp is rich in nutrition, grows rapidly, has high breeding output and good economic benefits. According to the "2012 China Fishery Statistical Yearbook", the annual output of grass carp farming in my country is 4.4422 mi...

Problems solved by technology

[0003] However, in the intensive farming mode of grass carp at present, in order to pursue high yield, the stocking density of grass carp is too high and a large amount of feeding, etc., lead to the deterioration of the environment of the culture water area, and the stress of the poor water environment will lead to the immune suppression of the cultured fish and increase the disease. chance of happening

Grass carp is a lower vertebrate, which is easily induced by stress damage caused by adverse environmental factors in aquaculture water, resulting in frequent occurrence of diseases. The survival rate from fry to adult fish is less than 30%, which has caused huge economic losses to the grass carp aquaculture industry. loss

In addition, in order to prevent fish diseases, a large amount of antibiotics and hormones are added to the feed, resulting in many problems such as drug resistance and drug residues, which have brought great harm to the sustainable development of aquaculture industry, aquatic product safety and human health.
