FISH MEAL

The whole or parts of various fishes can be used as a fishmeal after they have been dried or ground. Cooking fish and pressing to remove water and oil is preferred as this process sterilizes fishmeal produced by drying the cooked fish. It has high levels of protein, amino acids like lysine, methionine and tryptophan and minerals like calcium and phoshorus. Apart from these, fishmeal is rich in vitamin B complex and growth promoting effect of Animal Protein Factor (APF). Two main process are employed to process this sort of meals. Batch process (under vacuum) or a continuous process. In both the cases heating is carried out in steam jacketed vessels. Next one is Flame drying process in which meal is dried in a revolving drum by hot air from a furnace at one end of the drum. Fishmeal should be tested for salt toxicity, E.coli bacteria. Fishmeal has greatest usage in feeding simple-stomached animals due to high quality protein having adequate quantity of essential amino acids. Young animals need more fishmeal than the older ones because the young ones require high quality protein in addition to growth promoting factor. Such diets may include up to 10% of fishmeal. In older animals fishmeal is included at 5% and it may be eliminated entirely from diets for those in the last stages of fattening.
