The principle of operation of the extruder is as follows: the raw material is extruded through special filters creates a high pressure of 50 atmospheres, the temperature rises to 100-150. While there are various biological processes — cellulose is converted into secondary sugar, starch breaks down into simple sugars. High temperature disinfected products, neutralize harmful for birds and animals items.
After heating and pressure, the grains and beans out of the barrel of the extruder, the energy is abruptly released and an explosion occurs, food is increasing dramatically in volume. To demonstrate this process can cooking in the microwave beloved children of the popcorn.
Thanks ekstraktsii osaharivaniya straw, lignin out of it in the form of soluble humic acids, as a catalyst saccharification and calcium supplements is the lime. Salts of organic acids allows to absorb calcium in the stomach, as usual, but throughout the gastrointestinal tract.
Advantages of extruded feed has been demonstrated by numerous studies, these include:
- increase weight gain by 50-100%, reducing fattening time, for example, steers reach desired weight already after 1.2 years against 1.8 in the average diet;
- increase feed digestibility in 30-30%;
- reducing the cost of feed per unit of production by 7-12%;
- reduction of animal mortality from gastrointestinal diseases;
- increased milk production the production of eggs.
Among the disadvantages of extruded feed include relatively high price (which is justified considering the increase of production efficiency) and low humidity of the feed. On the one hand, dry food is convenient to store and use, no need to spend efforts on steaming, heating up, wash the feeders. With another animal need constant access to clean water when feeding.
To reduce the cost of feed and improve the nutritional value, manufacturers combine various grains and legumes. If the straw of wheat and rye is very low in nutrients, poorly eaten by animals and is almost never used when feeding, in combination with other crops if ekstraktsii it becomes healthy and tasty for animals, gets a nice grain smell, sweet taste and soft consistency. Thanks to the release of sugars in ekstraktsii from the diet of animals you can remove the Supplement, glucose and molasses, which also leads to savings.
