Double-spine cattle look at the "backbone" of the cow.

The backbone of double-backed cattle is flat, with a concave middle, and the back is straight without leaking the spine. Such cattle are called double-backed cattle. The backbone of single-backed cattle is convex. To see whether a cow has single-backed and double-backed cattle, you mainly need to look at the back of the cow. If the back is wide, it means double-backed. If the back is wide, it means single-backed. The key to single-ridged cattle and double-ridged cattle depends on their feeding environment. The main use of environmentally friendly and organic feed is that cattle will be better.
