Fish flour is a fodder of animal origin that is produced from sea-food processing waste and inedible types of sea animals.
1 ton of fish flour is made of 6 tons of fish raw material. In compliance with requirements of state standard (GOST 2116-2000) production of fish flour is executed with addition of antioxidant.
Fish flour is used as food additive during feeding of domestic animals, as well as in animals breeding, birds breeding, and fish farming. Fish flour contains great amount of proteins and amino acids that allows to enrich vegetable fodders with protein. Besides that fish flour is rich in vitamins A, B, D, E, it contains potassium, phosphorous, selene, iodine, and other minerals increasing growth of animals.
Because of these reasons fish flour is an important component of combined fodders (up to 10 %) and successively supplements components of vegetable origin. Due to its properties fish flour is successively used as fodder additives for animals being in the process of fattening.
Chemical composition of fish flour is specified in table 1.
Table 1. Chemical composition of fish flour
Quality of fish flour is determined by its fat content. If fat content is over 18 % the fish flour can not be stored for a long time. Besides, meat and milk of animals which used such fat flour obtain fish taste.
