Feed capable of improving crucian immunity

Abstract

The invention discloses feed capable of improving crucian immunity and belongs to the technical field of animal feed. The feed is composed of, by weight, 60-70 parts of corncob, 30-40 parts of rice husk, 25-35 parts of bran, 10-14 parts of modified dried lily, 4-6 parts of modified sophora flower, 3-5 parts of Chinese yam, 0.7-0.9 part of houttuynia cordata extract, 0.6-0.8 part of fulvic acid and0.3-0.4 part of tea polyphenol. The feed can provide balanced nutrition to crucian, improve own immunity of the crucian, lower sickness rate of the crucian and improve quality of the crucian. In addition, the feed is safe, environment-friendly, free of side effect to environment, high in bioavailability and great in market popularization value, and resource waste is well eliminated.

Description

technical field [0001] The invention belongs to the technical field of animal feed, in particular to a feed for improving the immunity of crucian carp. Background technique [0002] Crucian carp is mainly an omnivorous fish that eats plants. It likes to travel in groups and live by choosing food. The meat is tender and has high nutritional value. Every 100 grams of meat contains 13 grams of protein, 11 grams of fat, and contains a lot of calcium, phosphorus, iron and other minerals. Crucian carp has extremely high medicinal value. Its nature is flat and sweet, and it enters the stomach and kidney. [0003] Although the current large-scale aquaculture method has increased the production speed, it also faces many problems. In order to prevent aquatic animal diseases, a large amount of antibiotics are added to the feed, which not only does not slow down the aquaculture diseases, but also greatly reduces the quality of aquatic products. With the continuous improvement of peopl...

Problems solved by technology

[0003] Although the current large-scale aquaculture method has increased the production speed, it also faces many problems. In order to prevent aquatic animal diseases, a large amount of antibiotics are added to the feed, which not only does not slow down aquaculture diseases, but also greatly reduces the quality of aquatic products. With the continuous improvement of people's living standards, people's requirements for things are getting higher and higher.

Nowadays, fish meal, shrimp meal, honey, etc. are added to many feeds, and the cost is high, which is unacceptable to many aquaculture farmers

The existing crucian carp feed is supplemented with fishmeal and soybean meal as a source of protein, which provides macromolecular protein, which is not conducive to the digestion and absorption of crucian carp protein, and the utilization rate of protein is low. In addition, soybean meal contains antitrypsin, urease, and saponin Glycosides, goiter-inducing factors, etc., are not conducive to the digestion and utilization of feed by crucian carp

In order to speed up the growth of crucian carp and create greater economic benefits, existing farmers add a large amount of chemical ingredients to the feed and eat it for a long time, which will not only harm the body of crucian carp, but also cause harm to the human body after crucian carp is eaten by the human body. At the same time, it will cause water pollution and bring heavy pressure to the natural environment.
