When is a dairy cow artifitial inseminated before the milking period of 10 months end?

A dairy cow is not artificially inseminated before the milking period of 10 months ends. Artificial insemination is typically performed about 2 to 3 months after calving, which is the birth of a calf. This allows the cow's reproductive tract to recover and her body to regain the necessary nutrients before becoming pregnant again.
