1. Avoid being picky eaters. The compound feed formula has a variety of raw materials and is fully nutritious, which can prevent animals from picking their favorite food from the powder and refusing to take in other ingredients. Since pellet feed can maintain uniformity during storage, transportation and feeding, it can reduce feeding loss by 8%-10%.
2. High feed rate of return. During the pelleting process, due to the combined effects of water, temperature and pressure, the feed will undergo some physical and chemical reactions, which will gelatinize starch and increase the activity of enzymes, which enables the fed animals to digest the feed more effectively, which translates into weight gain. . Feeding poultry and pigs with pellet feed can increase the feed conversion rate (that is, the rate of return) by 10%-12% compared with powdered feed. Feeding fattening pigs with pellet feed has an average daily gain of 4%, and the feed-to-meat ratio is reduced by 6%; feeding broilers can reduce the feed-to-meat ratio by 3%-10%.
3. Storage and transportation are more economical. After pelleting, the bulk density of the feed will generally increase by 40%-100%, which can reduce the storage capacity and save transportation costs.
4. Good liquidity and easy management. Many powders, especially fluffy feeds with small specific gravity, often stick to feed silos with molasses or high fat and urea-added feeds. Because the pellet feed has good fluidity and seldom produces adhesion phenomenon, pellet feed is the most popular for those farms that use automatic feeders to raise dairy cows or poultry on a large scale.
5. Avoid automatic grading of feed ingredients and reduce environmental pollution. In the process of powder storage and transportation, due to the different volume and mass of various powders, it is easy to produce classification. After the pellets are made, there is no classification of feed ingredients, and the pellets are not easy to dust. During the feeding process, the pellets have much less pollution to air and moisture than powders.
6. Kill Salmonella in animal feed. Salmonella will remain in animal tissues after being ingested by animals. People who eat animals infected with this bacteria will suffer from Salmonella gastrointestinal problems. The method of steam high-temperature tempering and re-granulation can kill Salmonella in animal feed.
