Description

Technology Field

[0001] The present invention relates to fermented feed for livestock and a method for manufacturing the same. Background Technology

[0002] Livestock and the products derived from them (meat, milk, eggs, etc.) are important sources of protein, a nutrient essential for human survival. Therefore, the health and quality of livestock are directly related to human health. Meanwhile, the quality and composition of the feed consumed by livestock directly affect not only the health status of the animals but also the final products.

[0003] Traditionally, corn, soybean meal, sesame, barley, and rice straw have been primarily used as livestock feed; however, recently, the use of materials such as peanuts, peas, sugar beets, pulp, grain byproducts, animal offal meal, and fish meal has significantly increased. Despite the advantages of these feeds being nutritious and containing large amounts of protein, they have limitations because they contain a large amount of solid protein, making them difficult for livestock to digest. This results in low intake rates and causes intestinal problems. These issues with feed digestibility and absorption directly lead to a decline in the health and quality of the livestock. Furthermore, undigested feed excreted from the body causes severe odors due to high concentrations of ammonia and hydrogen sulfide. Prior art literature
