Why do cows reject their calves?

Are twin female calves sterile?
When a set of twins is born and one is a bull calf and the other is a heifer calf, more than 90% of the time the female is infertile. The infertile female twin is called a freemartin. This happens because early in embryonic development it’s common for the separate embryos to fuse and share the same blood supply.

Are twin bull calves sterile?

How long does a cow carry a calf before giving birth?
