Sex Lives of Cows

Submissive behavior
 The thing about dairy animals is that you have to breed them.

We choose to do our breeding via AI, or artificial insemination.

 I go shopping on line for the bull I would like to breed the girl with, and order the semen.
It is then sent to the vet's office and then I wait til the cow is ready to be bred. Then we take her to the vet and he inseminates her... easy as pie.

Lana is trying to chin rest
The trick is learning when the cow or heifer is ready to be bred. Every 21 days she will go into heat, and within  this cycle there is a period of 12 to 18 hours where she can be fertilized. Now let me tell you something, bull semen is not exactly cheap, and the postage and storage will all add up, so you really want to get it right the first time..

What you are about to get here is a little lesson on
learning when a heifer or cow is in "standing heat".

Sunny is standing to be mounted
 I would say it is next to impossible to determine a cow in heat that is  kept alone, really it is all about the behavior of the cows together that you need to be watching.

Initially other cows will "chin rest" on the animal going into heat, the animal going into heat will also
be more submissive as you can see in the photo of Sunny with her head under Lanas head.

Most importantly though is that the cow in heat will allow other animals to mount her, and she will stand for it, thus the term "standing heat".

Honestly, their behavior would make a sailor blush..
the cow in heat will try to mount everyone else, but they won't stand for it, they will walk a way, but the one in heat will stay put..... so after this hanky panky is observed, you have to get her to the vet to be bred 12 to 18 hours later....

It takes a little practice but after you know what to look for it's so simple....

Yet one more reason to thank god you're human.
