The ratio of male to female is about 8: 100.
If the newborn calf is female, raise it; If it is male, raise it at the ratio of 10: 1, and kill the rest at 9/ 10.
"Is the cow male or female?" The answer is yes. How to give birth to calves regardless of sex? It can be seen from this problem that people have different criteria for judging some concepts. First of all, what is a cow? If the cow is defined as an economic concept, a variety concept, not a biological concept, then there must be a male cow at this time. Then it must be a cow with black and white flowers, and it must be male and female. But if cow is defined as milking, it is neither male nor female, so different perspectives determine people's different ways of doing things.
Cow is a kind of cow. Not all cows that produce milk are called cows or all cows that have milk are called cows. Cows have horns.
There are different answers based on different concepts.
If the definition of "cow" refers to the kind of cow that produces milk, then there is no doubt that it includes males, that is to say, there are public females, at least for now. As for cloning or other parthenogenesis in the future, that is later. This is what people usually call a cow.
If the definition of "cow" refers to cows that can be milked, it does not include males. This is generally used in some specific occasions.
