Fish feed nutritional formula, use method, application and feed containing the nutritional formula

Abstract

The invention discloses a fish feed additive, an application method, application and a feed containing the additive. The fish feed additive comprises the following components in parts by weight: 1.27-2.19 parts of arginine, 0.95-1.69 parts of isoleucine, 0.3-0.75 part of vitamin K and 0.05-0.2 part of folic acid. According to the invention, by adding the feed additive in the range, the growth and development of the immune organs of fish are promoted, the specific and non-specific immune functions are improved, the capacity of the fish against aeromonas hydrophila infection is enhanced, the immune protection rate is improved, and the death rate under infection is reduced; and moreover, without the substances causing toxic and side effects on the fish body as well as antibiotic substances, the additive avoids pollution and drug resistance.

Description

technical field [0001] The invention belongs to the field of freshwater fish breeding, and in particular relates to a feed additive for freshwater fish, a use method, an application and a feed containing the additive. Background technique [0002] Fish products have high nutritional value, which is very important for improving dietary structure and improving human health. With the increasing awareness of health, consumers have higher and higher requirements for the consumption and quality of fish products. Carp and grass carp are the main freshwater aquaculture fish in my country, accounting for 33-40% of the total fish aquaculture output. However, in recent years, with the continuous increase of breeding density and pollution of the breeding environment, the incidence of various fish diseases has increased sharply, among which bacterial sepsis is one of the serious diseases of carp. [0003] Aeromonas hydrophila is the main pathogenic bacteria of carp epidemic sepsis. Th...

Problems solved by technology

[0004] At present, antibiotics and disinfectants are mainly used in production to prevent and treat fish diseases caused by Aeromonas hydrophila, and their long-term use has led to serious consequences: (1) Abuse of antibiotics has resulted in increased resistance of bacteria, making the treatment of fish diseases more difficult Difficult; (2) Disinfectants have large toxic and side effects, strong local irritation, and carcinogenicity, causing severe stress to fish; (3) Destruction of aquaculture water, pollution of the water environment, and reduction of fish immunity; (4) Increased drug residues, aquatic products Worrying about safety, declining quality, endangering human health
