Because rectal palpation is the cheapest way of finding out whether a cow or heifer is pregnant or not (and "how pregnant" or rather, how far along they are). The uterus is located just below the rectum, and can easily be felt by an experienced producer or veterinarian. It's a lot cheaper than having an ultrasound done, or an ELIZA exam, and quicker a blood test, and can be performed by anyone with a little bit of training and practice and who doesn't mind sticking their arm into the rectum of a cow.

How do you tell if a cow is pregnant by doing rectal palpation?

You need to stick your arm into the rectum of the cow, then feel down for the ovaries. If you feel a large lump or something that is bumping against your hand as you feel downwards, then the cow is bred. If you feel nothing, then the cow is open.


How do you preg check a cow?

A veterinarian can perform a rectal palpation or ultrasound exam to determine if a cow is pregnant. During a rectal palpation, the vet inserts an arm into the cow's rectum to feel for the presence of a fetus. An ultrasound exam uses soundwaves to visualize the reproductive tract and confirm pregnancy.


How are cows artificially inseminated?

There is a fully detailed article that answers this question in full which can be read in the related link below. Basically, though, a cow is artificially inseminated by a person having one arm up the cow's rectum to hold the cervix through the colon wall and the other arm manipulating an AI gun with a semen straw in it through that cervix into the cow's uterus. Once the tip of the gun is in the cow's uterus, semen is deposited into her. A cow can only be successfully AI'd if she was recently in heat. Otherwise she will not take nor get pregnant. Use of artificial hormones can help a producer synchronize several cow's heat cycles so that they can be AI'd all together in one day.

Do shots go in your butt?

Some can. It's frequently the site of choice for intramuscular shots. SubQ (subcutaneous) shots usually go in the belly. Intravenous shots usually go into the lower arm somewhere; the wrist, the back of the hand, and the inside of the elbow are all places where there's a fairly large vein close to the surface.
