The powder in the cow's small intestine is not feces, but a substance secreted by the mucosa and glands on the intestinal wall. In the digestive system of cattle, food passes through the stomach and enters the small intestine after initial digestion.

The secreted material forms a white or pink film inside the small intestine.
