Inside an outdoor pen, a calf is nursing from a cow. The calf is primarily black with white markings. It is standing and has its head nestled under the cow. The cow is mostly dark brown and black with some white patches. She is standing still while the calf nurses. The pen is constructed with white metal bars, and the ground is covered in dirt and hay. Trees are visible through the pen's structure in the background.
