In recent years, domestic aquaculture has developed rapidly, but under the condition of high-density aquaculture, how to achieve rapid growth of fish, shrimp and crabs, shorten the breeding cycle, reduce the feed coefficient, enhance the physique of cultured animals, reduce the occurrence of diseases, and improve the survival rate is an urgent problem for high-quality aquaculture. The essence of aquaculture is to realize the transformation from low protein (food protein) to high protein (fish and shrimp meat). How to make breeding animals more efficient in the absorption, utilization and transformation of low protein is the fundamental solution to the rapid growth of breeding animals.
After years of research and development, Shanghai Norris has successfully developed the "really fast" product with the Royal Swedish Agricultural College. Use polypeptide genetic engineering technology and molecular biology technology to complete the recombination of compound protein peptide, promote the absorption and transformation of amino acids in cultured animals, promote the development of intestinal villi and the secretion of digestive enzymes, and improve the growth of cultured animals.
Action mechanism
Small peptide is an important component of animal nutrition protein. Small peptide can be absorbed in complete form and used by tissues. Moreover, the absorption mechanism of small peptide and amino acid is completely different and does not interfere with each other. In digestive physiology, small peptides have the advantages of fast absorption, low energy consumption, non saturation of carriers, non competition and inhibition of transportation between various peptides, and thus have obvious advantages over amino acids in absorption and metabolism.
It is really fast to use biological enzymolysis technology to hydrolyze soybean protein, animal intestinal mucosa, fish plasma protein, animal plasma, rice protein, wheat protein and other protein substances into complex protein peptides. The content of compound protein small peptide is more than 60%, and the small peptide with molecular weight less than 1000 daltons accounts for 78%, which can significantly improve the digestibility and absorption rate of nutrients, so as to reduce the feed coefficient or feed meat ratio, shorten the breeding time, reduce the breeding cost, and increase economic benefits.
Product features
1. As a short intestinal aquatic animal, Penaeus vannamei has a low ability to digest and decompose proteins and a low immunity. It needs to consume energy to synthesize proteins to affect the growth of the shrimp. The "really fast" produced by biological enzymatic hydrolysis contains a variety of active small peptide substances (glutathione, casein enkephalin, carnosine, antibacterial peptide, etc.), which have a strong role in inducing food and promoting growth. Since the small peptide can be directly absorbed and utilized without decomposition, its growth promoting function is well reflected in the culture of Penaeus vannamei.
2. Amino acids in the form of small peptides can be rapidly absorbed, because the absorption mechanism of small peptides has the characteristics of not easy to saturate the carrier, low energy consumption, and fast transport speed, and can alleviate the competition of intestinal cells for the intake of different free amino acids. Some small peptides can promote the early maturation of small intestine of young animals, promote the growth of small intestinal villi, improve the digestion and absorption function of the body, thus improving the utilization rate of protein in feed, i.e. feed conversion rate.
3. It is really fast to produce by biological enzymatic hydrolysis, and also contains a number of functional immunoglobulins and antibacterial peptides, which can significantly improve the immune ability of animals, increase vitality and reduce disease.
