Do bulls mate with the same cow twice?

This theory supposedly came up after a little experiment with a bull. The bull was locked in with a cow that he gladly mated with. But when another cow was brought to the bull, he gladly mated with the new cow. The Old Cow Theory, therefore, states that a bull will mate only once, never twice with the same cow.

When replacement heifers are kept from within the herd, close inbreeding will occur when a bull is used for three or more years.
