What are the characteristics of cattle and sheep sleep?

When a sheep sleeps, it kneels on its forelimbs, then lies on its back, with its head and neck raised, and its forelimbs bent towards its abdomen, showing a semi-lateral posture. There are also some forelimbs that stretch forward, with the head and neck resting on the forelimbs and the hind limbs facing forward and pressing under the abdomen. If you lie on your side and your limbs are stretched out, you may be ill. Feeling dark, the sheep went to bed.

Cattle in different areas sleep with their eyes closed. Usually, cows living on sunny grasslands will sleep with their eyes open. Because they live in sunny areas, their eyesight is not very important, so their eyes become very small, or even completely degenerate. It doesn't matter if they naturally close their eyes when they sleep. And cattle live in areas with insufficient sunshine. Because the light there is very weak, their eyes are very big, otherwise they can't see anything. It doesn't matter how big your eyes are. What's more, I'm worried that things like bugs will affect my sleep, so I close my eyes and sleep.
