Eight advantages of extruded feed
With the growing demand for "green food" from consumers, the current aquaculture industry is gradually developing from quantity to quality. At present, most places have formed a new mode of processing and breeding with extruded feeds as the mainstream. Why is extruded feed so popular?
1. The puffed feed has good palatability, and can effectively avoid feed grade change, and it will not affect the use effect due to uneven nutrition.
2. Various pressures and mechanical actions in the expanding process can increase the gelatinization degree of starch in the feed, destroy and soften the cell wall portion of the fiber, denature the protein, increase the stability of the fat, and improve the digestibility and utilization of the feed. At the same time, fat penetrates from the inside of the particles to the surface, so that the feed has a special fragrance, which is conducive to increase the animal's appetite;
3, feed ingredients after high temperature, high pressure puffing can kill a variety of harmful bacteria, thereby effectively reducing the body's digestive tract disease;
4, can be made into a variety of sedimentation rate of extruded feed, such as buoyancy, slow Shen and Shen, in order to meet the requirements of different living habits of aquatic animals, reduce feed loss, to avoid water pollution;
5, according to animal preferences to produce different shapes of products, such as cat feed can be produced fish shape, dog feed can be made into a rib-shaped, thereby greatly improving the appearance of feed and attracting food value;
6. Some young animals with underdeveloped digestive organs or fur animals with short digestive systems can hardly digest complex feeds and can use expanded feeds that are easier to digest and absorb.
7, has a special role in the development and utilization of feed resources, such as the use of extruder to produce full-fat soybean (4387, 3.00, 0.07%) powder, expanded feather powder, blood meal, etc.;
8. Extruded feed has a low moisture content and is convenient for long-term storage.
