Bulls may mount her, however, there is not an egg present so she will not catch or become pregnant.
No. Cows either have false heats, cystic ovaries or anestrus, never false pregnancies.
A false heat is when a cow goes in heat or estrus but doesn't ovulate. False heats may occur when a female is pregnant, and are not common either.
An Angus cow is able to breed anytime she is not pregnant and in heat.
No, not usually. On rare occasions, a cow may experience false heats during pregnancy where she can be ridden by a bull, but otherwise, a cow that is pregnant stays pregnant and doesn't go into heat until a couple weeks after she's given birth.
between 40 and 60 you should let her have a heat to clean out some then breed her the second heat
If she's in heat, most definitely. Often a bull will go look for the cow that is in heat, no matter if he's the neighbor's bull or not.
When she goes into heat. A cow can only be bred if she's in heat. If not, then it's not worth the effort to breed her. See the related question below.
Yes.
Not usually, no. If she is having more than one "false" heat, chances are it's not false at all. She probably absorbed the embryo or aborted early and came back to heat soon after.
The rule of thumb is that you need to breed a cow 12 hours after you see her show signs of estrus or heat. A bull will typically mate a cow during her heat period, but not when she's not in heat, which is the rest of the 17 to 24 days that she's not in heat.
You don't. You can only breed a cow with a bull.
No you can't breed a deer with a cow i don't think there such thing as a deow.(cow deer)
