Characteristics of aquatic feed

Different animals because of its different digestive system, so the degree of digestion and secretion of enzymes also show different characteristics for aquatic animals, that compared with other animals, the digestion level is low, the digestive system is not developed, so its digestive enzyme secretion and the number of species is relatively low. Therefore, the characteristics of aquatic feed and animal feed is different, what are the aquatic animal nutrition feed’s characteristics?

(A) aquatic animals to digest the enzyme

Different animals because of its different digestive system, so the degree of digestion and secretion of enzymes also show different characteristics, for aquatic animals, compared with other animals, the digestion level is low, the digestive system is not developed, so Its digestive enzyme secretion and the number of species is relatively low. 


(B) the difference between aquatic animals and livestock and poultry nutrient feed

As the digestive system of aquatic animals and shrimp, livestock and poultry animals vary widely, so the feed ratio should be based on its digestive system composition, structure and digestive enzyme species and the living environment to conduct a comprehensive analysis, with Than for the aquatic animal physiological needs of the nutritional feed. 


Specifically, first, the digestion of aquatic animals is small, so its energy demand is low, only about half of terrestrial organisms, so the ratio of feed to the energy value should be adjusted accordingly, not too large. Second, the protein demand for aquatic animals is relatively high due to physiological characteristics. 


Generally speaking, the protein content of aquatic animal feed should be between 22% and 55%, compared with the increase in livestock and poultry feed Nearly doubled. Once again, aquatic animals have a higher demand for vitamin C, vitamin A and vitamin B, and are less sensitive to vitamin D requirements, so they should be properly equipped when dispensing. Finally, the crushing capacity of aquatic animal feed is small, and the feed has a high degree of stability to the water. Therefore, it is necessary to avoid the processing of aquatic animal feed with high temperature and high pressure.
