Maize (2406, -15.00, -0.62%) is used for feed-based grain, meridian and forage, and corn stalk is also an important production resource for industrial and agricultural production. As a resource, corn stalks are rich in nutrients and available chemical ingredients that can be used as feedstock for livestock feed. For a long time, corn stalks have been one of the main raw materials for livestock. The test results show that corn stalk contains more than 30% carbohydrate, 2% to 4% protein and 0.5% to 1% fat, which can be silaged or directly fed. In the case of herbivores, the net weight gain of 2kg corn stalks is equivalent to 1kg of corn kernels, especially after silage, yellow storage, ammoniation and saccharification, which can improve the utilization rate and the benefits will be more substantial. According to research and analysis, the digestive energy contained in corn stalk is 2235.8kj/kg, and it is rich in nutrients, and the total energy is equivalent to that of pasture. The fine processing of corn stalks to produce high-nutrition livestock feed is not only conducive to the development of animal husbandry, but also through the straw to the abdomen, and has good ecological and economic benefits.
Corn stalk feed processing technology is a technology that uses mechanical engineering, biology and chemistry to complete the process of harvesting, feed processing, storage, transportation and feeding from corn stalks. In recent years, with the rapid development of China's animal husbandry, new technologies for straw feed processing are emerging. In addition to feeding directly as feed, corn stalks are now widely used in physical, chemical, biological and other processing technologies, achieving centralized and large-scale processing and opening up new ways for feed utilization.
The corn straw granule feed processing technology is to smash the corn stalk after drying, and then add the additive and mix well, and extrude it into a pellet feed by a grinding plate and a pressing wheel in the pellet feeding machine. Due to the friction and heating during the processing, the internal ripening degree of the straw is deep, and the processed feed particles have a smooth surface, moderate hardness and uniform size, and the granule diameter can be adjusted between 3-12 mm as needed. It can also be applied to the complete equipment of pellet feed, which can automatically complete the functions of straw crushing, lifting, stirring and feeding. It can add various additives at any time, and it can be fully enclosed and produced with high degree of automation. Small and medium-sized corn straw pellet feed processing enterprises should use this technology. .
