China is a major producer of livestock and poultry, and corn is the main raw material in their daily diet. Improving the utilization efficiency of corn is one of the important measures to promote China's livestock and poultry production, save feed resources, and alleviate the shortage of feed in China.
The particle size of corn grinding has a significant impact on the nutrient metabolism, digestive tract development, and production performance of livestock and poultry. Studies have shown that appropriate grinding of corn can significantly improve feed conversion rate and animal production performance, and is beneficial to feed processing. However, although excessively fine ground grain feed can increase feed utilization rate and reduce waste, it will also increase processing costs and cause digestive tract diseases in livestock. In recent years, it has been considered that appropriately increasing the particle size of corn grinding is beneficial to increase the feed intake of poultry, prolong the residence time of chyme in the digestive tract, improve the physiological condition of the gastrointestinal tract, and thus improve the production performance of poultry. The particle size of grain feed is affected by factors such as variety, drying conditions, storage conditions, crusher, and sieve hole diameter. After grain storage, the tissue hardens, flexibility and toughness weaken, and the texture becomes brittle. In addition, the particle size of corn may also be related to its water content and hardness.
