Enzymatic Hydrolysate of Functional Protein: Protect the Health of Fish Liver

During the peak season of aquaculture production, the feeding amount and cultivation density have increased. Meawhile, the incidence of fish liver problems occurs accordingly, which seriously affects the health of fish. When we dissect the fish body, the appearance of liver pathology, liver fibrosis, liver necrosis and other phenomena can be clearly observed.

Why fish liver prone to pathological changes?

1. Liver cell membranes are rich in polyunsaturated fatty acids, which are easily damaged by oxidation

Regardless of whether it is freshwater fish or marine fish, the content of polyunsaturated fatty acids on liver cell membranes exceeds 30%, while the content of polyunsaturated fatty acids on human liver cell membranes is only 7%. Polyunsaturated fatty acids are extremely unstable and are easily attacked by free radicals and oxidation damages, and causing various liver diseases.

2. The generation of free radicals in aquaculture is inevitable

Free radicals are the generated wastes when organisms obtain bio-energy, it is like the emitted exhaust gas when car consume oil. When fed with high protein and fat feed in high breeding density, the energy metabolism will be more vigorous and more free radicals will be produced. Thus the fish liver is more susceptible from oxidative damage, which will cause various liver diseases.

Therefore

It is an effective measure to protect liver health by effectively scavenging excessive free radicals in aquatic animals, enhancing the antioxidant ability of liver, reducing the oxidative damage of free radicals to hepatocytes, maintaining its structural integrity and normal function.

The functional protein from Mytech with enzymatic hydrolysis technology, it is not only a product with high digestion, absorption and utilization rate and low anti-nutritional factors, but also contains a large number of small molecule active peptides, especially antioxidant active peptides. Studies have shown that these small molecule active peptides can promote the development of functional organs, enhance the body’s antioxidant capacity, ensure the integrity of cell structure and normal function, and promote liver health.

Product research & application cases

NO. 1

Research institutes: Cooperated with Laboratory of Aquatic Animal Nutrition, Sichuan Agricultural University

Research fish：Common Carp

Result: The amount of oxidation products in carp liver is reduced by 10%, and the activity of antioxidant enzymes is increased by 5%

NO. 2

Cooperation customers: Sichuan *** Feed Company

Research fish: Ietalurus Punetaus and Gymnocypris przewalskii

Results: 1. Ietalurus Punetaus: add 1% enzymatic functional protein and reduce 1% imported fish meal, after feeding for 1 month,

A. The liver color and the health condition are significantly improved

B. The proportion of abdominal fat in internal organs is reduced by 12%

(Improve liver health, promote the catabolism of liver fat, reduce the proportion of abdominal fat, and enhance the body's anti-stress ability such as stress resistance and transportation)

2. Ietalurus Punetaus: In 2020, 1% enzymatically hydrolyzed functional protein replace 1% imported fish meal. (It is obvious that compared with last year, the proportion of abdominal fat in internal organs is controlled within 30%, and most of the fat contents is used in order to decompose and energy supplement, and protein is used to deposit for body tissues, and the growth of the fish body is significantly improved.)

Table 1 The total viscera, liver and abdominal fat indexes of Ietalurus Punetaus for each sample

3. Gymnocypris przewalskii: add 1% enzymatically hydrolyzed functional protein to replace 1% imported fish meal. (Repeated samples show that the liver and pancreas are rosy and elastic)

During the peak season of aquatic production, protecting liver health is the top priority! The enzymatic hydrolysate of functional protein of Mytech is rich in anti-oxidation and small molecule active peptides, which can effectively remove excessive free radicals in fish, ensure the integrity and normal function of liver cells, and maintain the health of fish liver!
