Grass carp feed and preparation method thereof

Abstract

The invention discloses a grass carp feed and a preparation method thereof, belonging to the technical field of animal feeds. The grass carp feed comprises the following raw materials in parts by weight: 5-10 parts of fish powder, 1-5 parts of rice bran, 1-2 parts of monocalcium phosphate, 0.5-1 part of distillers' grains, 1-3 parts of bentonite, 5-10 parts of rapeseed meal, 1-5 parts of soybean meal, 1-5 parts of wheat bran, 3-9 parts of corn powder, 3-5 parts of alfalfa powder, 1-3 parts of compound vitamin, 3-9 parts of hawthorn fruit and 1-5 parts of indigowoad leaf. The grass carp feed does not contain antibiotics or hormones, not only can meet the requirement for plenty of nutrient elements for growth of grass carps but also has low morbidity and good feeding attraction property, and can conduce to obviously increasing the growth rates of the grass carps and increasing the feed conversion rate. Meanwhile, the preparation method is simple, is low in cost and is suitable for large-scale production.

Description

technical field [0001] The invention relates to a grass carp feed and a preparation method thereof, belonging to the technical field of animal feed. Background technique [0002] Grass carp is one of many freshwater fishes in my country. It is favored by consumers for its tender meat, large body, and few intermuscular spines. However, grass carp has poor disease resistance and a low survival rate, and is extremely vulnerable to the "four diseases of grass carp (the four diseases of grass carp are red skin disease, gill rot, enteritis and hemorrhagic disease)" during the breeding process. Chemical farming has been severely restricted. Long-term production practice has proved that injecting antibiotics into grass carp can prevent the "four diseases of grass carp"; however, these antibiotics will enter the human body along with people eating various fish products, which indirectly leads to the abuse of antibiotics, which may lead to multiple drug sources. Diseases, and even n...

However, grass carp has poor disease resistance and a low survival rate, and is extremely vulnerable to the "four diseases of grass carp (the four diseases of grass carp are red skin disease, gill rot, enteritis and hemorrhagic disease)" during the breeding process. Chemical farming has been severely restricted

Long-term production practice has proved that injecting antibiotics into grass carp can prevent the "four diseases of grass carp"; however, these antibiotics will enter the human body along with people eating various fish products, which indirectly leads to the abuse of antibiotics, which may lead to multiple drug sources. diseases, and even produce new "super drug-resistant bacteria", so this grass carp breeding method seriously threatens human life and health
