Green ecotype crucian carp feed

Abstract

The invention discloses a green ecotype crucian carp feed. The feed is prepared from the following raw materials in percentage by weight: 10-11% of flour, 10-12% of green bran, 3-4% of DDGS (Distillers Dried Grains with Solubles), 8-13% of bean pulp, 28-32% of rapeseed meal, 10-17% of cottonseed meal, 9-16% of fish meal, 2-3% of soybean oil, 0.8-1% of phospholipid oil, 0.15-0.20% of salt, 2.2-2.4% of monocalcium phosphate, 0.10-0.15% of choline, 0-2.5% of zeolite powder, 0.5-0.8% of premix compound and 0.10-0.20% of compound additive. By adopting the technical scheme, the effects of high crucian carp growing speed, low feed coefficient, low frequency of occurrence of diseases, low death rate, less use of drugs and low frequency of occurrence of floating heads are achieved and the crucian carp breeding cost is reduced.

Description

technical field [0001] The invention relates to an animal feed, in particular to a green ecological feed for crucian carp. Background technique [0002] Since the reform and opening up, my country has implemented the fishery development policy of "mainly raising fish". In 2006, my country's freshwater aquaculture output reached 21.4831 million tons, accounting for 59.78% of the total aquaculture output (35.9395 million tons). Among them, the breeding scale and breeding potential of crucian carp are increasing, and its total annual output has exceeded 2 million tons by 2005. It can be predicted that the proportion of crucian carp in freshwater aquaculture will become larger and larger in the next decade or even decades. However, behind the rapid development of the crucian carp farming industry, the problems exposed by itself are worrying. The current crucian carp farming model mostly starts from the pursuit of output and economic benefits, and uses high consumption and hig...

However, behind the rapid development of the crucian carp farming industry, the problems exposed by itself are worrying

The current crucian carp farming model mostly starts from the pursuit of output and economic benefits, and uses high consumption and high input of feed and medicine in exchange for high output, resulting in serious water pollution, deterioration of the ecological environment, decline in fish immunity, and more and more diseases. More and more, the etiology is more and more complicated, especially intestinal and liver lesions, leading to high mortality rate, and at the same time, there are more and more types of medicines, and the cost of medicines is getting higher and higher, but the effect is not satisfactory

At the same time, more side effects are produced, such as: ①Drug residues in aquatic products endanger human health, such as "three causes", allergies, and even diseases or potential hazards that humans have not yet understood at the current scientific level

②The microbes in and out of aquatic animals are resistant or resistant to antibiotics, the efficacy of the medicine is reduced, and the dosage of the medicine is continuously increased, which increases the cost of breeding and makes the drug residue more serious, forming a vicious circle

④ Make aquatic animals dependent on antibiotics, inhibit the growth and development of the animal's immune system or reduce the animal's immune function, and reduce disease resistance

⑤ Residual bait and fish excrement that have not been eaten by fish enter the water body, increase oxygen consumption, pollute the water body, and produce toxic and harmful substances

It is difficult to achieve the purpose of healthy breeding and ecological breeding, and to obtain green and healthy pollution-free crucian carp aquatic products
