New generation of fodders

A. Obtaining protein from fish broth
While producing fish meal, the fish is boiled. Part of meat and bones go to drying room, and fish broth goes to further processing.
During the first stage, fish fat is separated from the broth. Then the broth, significantly devoid of fat, goes to thickening system where water is evaporated with use of thermal method. When the process is complete, fish protein concentrate is obtained, of thick liquid consistence where dry matter content is 45%. Such concentrate is then mixed with a mixture of corn of reduced grain size in proper ratio and goes to extrusion process. In adequate temperature and at high pressure in extruder, process of refining of the product is executed.
Having completed the extrusion, the product is cooled. When it exits the extruder, it is in the form of flakes. Depending on use, the flakes may be crushed, granulated, ground into flour or squashed. It is possible to change proportion of corns to any other ratio, as well as the degree of moistening of ground corns with fish protein concentrate in the range from 0 to 50% of share of fish meal from liquid concentrate in total mass. In the case of ready piglet fodder we use up to 15% of meal obtained from fish broth.
The product may be in the form of concentrate with portion of required and adequate for a given animal quantity of fish ingredients or ready fodder.
Uniformity of saturation with fish protein in the form of liquid concentrate and fish fat gives homogenous and evenly saturated product, which has beneficial influence upon quick absorption of ingredients and high digestibility. Presence of fish fat from cod liver with exogenous fatty acids has very favourable impact upon all functions of a young organism. Digestion of the product begins already in technological process. Obtained particles of product are characterized by easy softening in oral cavity and stomach of a piglet. The process is much quicker than in the case of raw ground grains or granules of conventional fodders filling a young stomach.
When feeding piglets and chickens with more digestible protein, it is possible to use less volume of fodder while keeping the same or better gains.
The above technology allows more precise proportioning of fish ingredients in fodder and better distribution in mixture.
