Fish meal, as an important part of animal feed, always has high market prices. In particular, fish meal products from Chile, Peru, Indonesia, and other countries have always occupied an important position in the international market. Why is fish meal price so expensive? What nutritional value does fish meal have? Fish meal machine manufacturers will answer your questions here.
The protein content of the high-quality fish meal is above 60%, and some are as high as 70%; The various amino acids in fishmeal are high and balanced, so their biological value is also high, which is a good animal feed for balancing poultry diets.
Fish meal contains high fat, and imported fish powder contains about 10% fat; domestic fish meal standards are 10% -14%, but some are as high as 15% -20%. However, its fat is easy to oxidize, which often causes vitamin A and vitamin E to be deficient with the oxidation of fat. At the same time, the temperature of fat oxidation rises, which is one of the causes of spontaneous combustion of fish meal.
Fish meal contains 3.8% -7% of calcium and 2.76% -3.5% of phosphorus. The better the quality of fishmeal, the higher the phosphorus content, and the utilization rate of phosphorus is 100%. However, during storage, due to chemical decomposition, phosphorus is released and becomes elemental phosphorus. Elemental phosphorus has a low ignition point and can ignite spontaneously without an open flame. This is the second reason why fishmeal is liable to spontaneously ignite during storage.
