What are the nutrition of dairy cows?

Crude fiber is an essential nutrient for dairy cows, which can not only provide energy and raw materials for synthesizing glucose and milk fat, but also maintain the digestive function of dairy cows. Crude fiber is stable in nature, difficult to digest, large in size and strong in water absorption, and can fill the digestive tract to give animals a sense of fullness. It can also stimulate the mucosa of digestive tract, promote the peristalsis of digestive tract, promote the discharge of undigested substances, and ensure the normal function of digestive tract.
