Excessive consumption of raw materials such as corn, sorghum, barley, fresh sweet potatoes, and dried sweet potatoes by cattle and sheep not only grows slowly, but also causes illness. Cows and sheep are ruminants and have four stomachs: rumen, honeycomb, stomach, and stomach. The first three stomachs are collectively referred to as the foregut. There are a large number of bacteria and protozoa among the rumen, especially between the rumen. They can digest and decompose the crude fiber in the feed. This is the main reason why cattle and sheep can make heavy use of roughage. one. At the same time, cattle and sheep have the characteristics of rumination (the masses call it counter-milling), which can spit back into the oral cavity and then chew them. Therefore, in actual feeding, the cows and sheep must have sufficient ruminating time to ensure their normal digestive function. Bovine stomach volume accounts for about 70% of the entire digestive tract, sheep's stomach about 67%, and their rumen volume accounts for about 80% of the entire stomach volume. Therefore, in the actual feeding of cattle and sheep, in order to meet their fullness, large feed such as green feed and roughage must be fed, which is the physiological requirement of cattle and sheep. The raw grain should be fed, but it should not be the staple food for cattle and sheep. It should be more appropriate to use roughage fiber as the staple food and properly mix the raw grains.
