1. Improve digestibility of animal feeds, 10% conversion rate.
2. Reduce picky of animal feeds.
3. Economic storage and transportation as saving about 40-80% volume by higher density.
4. Avoid classification of feeds ingredients when packing, storage and transporting.
5. Reduce environment pollution.
6. Shorten feeding time, enhance feed intake and growth rate.
7. Salmonella---harmful to human and animal, will be killed by high temperature and high pressure when pellets processing.
8. Reduce wasting by winds and intake, about 8-10%.
9. Easy to accept by animal when changing different digestibility(Different digestibility needed by different growth stages).
