How do you perform a pregnancy test with a rabbit?

Urine is injected into the rabbit, sometime later the ovaries of the rabbit are inspected. They respond to pregnancy hormones in some way (grow?) that can be seen.
 
It is very difficult. Chasing a rabbit around the yard and getting it to pee on a test strip is almost impossible. That is why there is so many unexpected pregnacies in the bunny world! Sorry, could not help myself.
 
A woman pees on the rabbit. Then she takes the stick and rubs it on the rabbit. The rest is easy, 1 bar this, 2 bars that...

This^^^. I remember when someone found out they were pregnant they would say " The rabbit died ".

They have also used frogs and mice.
 
"The rabbit died" is a little bit misleading, since the rabbit died whether the woman was pregnant or not. Something in a woman's urine causes growths on the ovaries of the rabbit if she is pregnant. The rabbit is killed during the inspection of the ovaries either way.
 
Very interesting read. Why can't the hormone identified with rabbit pregnancy be used to test in the rabbits urine? It's the same principle for humans. Beta HCG (human chorionic gonadotropin) is what identifies pregnancy in females, although it must be above 0.05 in their urine (i think that's the correct number, I'd have to go back and study my physiology again).

I don't know if science has identified the hormone responsible in rabbit pregnancy.

Because the whole rabbit thing was from back before we could identify hormones, or proteins and create dyes specifically crafted to bind with those proteins as you see on a urinary pregnancy test. I mean, if you could determine whether or not a rabbit is pregnant from it's urine.... what do you need the rabbit for?
