"The corn is a treasure, all livestock can not be separated" is a popular saying that the corn is a good feed for livestock and poultry. Corn kernels, straw, and cobs are all rich in nutrients.
Corn kernels have 68-70% carbohydrate, 8-10% protein, 4-5% crude fat, and various minerals and vitamins. Some studies have reported that the nutritional value and digestibility of corn are higher than those of barley, oats and sorghum, especially high-quality protein corn, ie, high-lysine corn, and that lysine and tryptophan that can be used by humans and animals are high. Good feed crops. Corn is the main energy feed source in China, and more than 80% of the total annual production is used as feed. Corn stalks contain more than 30% carbohydrates, 2-4% protein, and 0.5-1% fat. Corn stalks can be either silaged or fed directly. About 200 billion kilograms of corn stalks are produced each year in the country, which is a huge potential source of feed. For herbivores, a net energy gain of 2 kilograms of corn stalks is equivalent to 1 kilogram of corn kernels, especially corn silage silage. After the yellowing, ammoniating, and saccharification treatments are performed, the utilization rate can be greatly increased, and the benefits will be more significant. The corn cob contains 45-55% carbohydrate, l-3% protein and 0.5-3% fat. After a certain processing, are the best source of feed. Here, we mainly introduce the by-product feed and straw processing technology using corn as raw material.
