Pig pellet feed is one of the formulated feeds, which is a kind of granular feed made from full price mixture and extruded. It's usually cylindrical.
The advantages of pellet feed for pigs are as follows:
1. Easy to store, package and transport
After the feed is shaped, the volume of pellet feed is reduced by about 1 / 3 compared with that of powder feed, which is convenient for storage, packaging and transportation. During the storage process, the powder feed is easy to absorb moisture, caking and moldy. Under normal circumstances, it can only be stored for 7-10 days. However, the pellet feed has good dispersibility, low hygroscopicity and high storage stability. Under normal circumstances, it can be stored for 35-45 days, and the storage time is 4-5 times as long as that of powder feed; the finished product is finished In the process of transportation, it avoids the phenomenon of automatic classification, and reduces the loss of dust and trace components in the process of packaging and use.
In the process of pelleting, some toxic substances or inhibitors (such as trypsin inhibitor and hemagglutinin) in feed are destroyed by heat. At the same time, it can kill 90% of Salmonella.
3. Improve the palatability and feed intake of pigs
Due to the high density, reduced volume and high nutrient concentration of pellet feed, the raw material components (corn and soybean meal) emit natural fragrance after granulation and ripening by processing technology, and the palatability is significantly increased, so the feed intake of animals is also significantly increased.
4. It is convenient for pig to digest and absorb and improve feed utilization rate
Through granulation and ripening, the physicochemical properties of some nutrients in feed were improved, and the utilization rate of nutrients was also improved.
5. Prevent pigs from picky eating and reduce feed waste
Due to the uniform size and comprehensive nutrition of pellet feed, the integrity and full price of the diet components were ensured, and the feed selection according to its palatability was avoided. Pellet feed can reduce the loss caused by flying dust in the air and water. Due to the large amount of dust in the feed powder, the feed dust in the air provides a comfortable living environment for pathogenic microorganisms. In the current situation that respiratory diseases exist everywhere in pig farms, the dust with pathogenic microorganisms enters the respiratory tract of pigs to induce respiratory diseases, which makes it more difficult for technical personnel to control respiratory diseases There is little dust,
The actual situation has proved that the pig pellet feed has fewer respiratory diseases and is easier to control; moreover, the pellet feed is easy to identify. For example, the size of pellet feed for piglets, growing pigs and finishing pigs is from small to large, which can reduce the waste caused by feeding mistakes of employees.
