[0002] The grain-consuming livestock and poultry industry, which uses corn, soybean meal and other raw materials to process feed for feeding livestock, is the main form of livestock breeding in China. In China, corn, soybean meal and other feed raw materials rely heavily on imports, while the demand for protein feed in the livestock industry is increasing, which has a serious impact on China's food security. Therefore, it is urgent to accelerate the development of grain-saving livestock and poultry industry. Optimizing the structure of grass-eating poultry feed, increasing the proportion of high-quality forage in cattle and sheep breeding, and promoting "forage instead of feed". Mixing forage and feed in a certain proportion to prepare high-quality forage can not only improve the palatability of traditional feed and increase the foraging capacity of livestock and poultry animals, but also meet the growth needs of animals. It can also achieve the reduction of soybean feed and effectively reduce the demand for grain feeding of livestock and poultry animals.
