Show me your PMUs!

Here's my PMU! He's the big white one ;) He is 8 years old and 18.2hh. His name is Dozer. You guys all ave beautiful horses too!

I work in pharmaceuticals, but knew about Premarin before I started working. When I started at my pharmacy, I explained what Premarin was and how it was obtained to both my patients, and my boss. Before my 3rd month at that company, my boss pulled it from the shelves and started telling people to get it elsewhere. It was pretty awesome.

But I have a question... are most of the PMU horses draft breeds? Also are most of the "companies" that produce the conjugated equine estrogen, out of business? There doesn't seem to be as much of a demand for this product as there was in previous years.

A lot of PMU horses are drafts or draft crosses because of the volume of urine they could produce verses a lighter breed.

I'd also assume that with the PMU business down the drain, that marketing of thse drugs would be low if not void at this point.

The drafts also had the temperament required.
Business slowed partly due to awareness of how the product was made & also due to long term complications of use like some cancers. There is a synthetic product available now.

What is the umm.. substance.. even used for?

Birth control pills I believe.

If you look up the product Premarin, it's a hormone therapy drug for women with menopaus. It stands for PREgnant MARes urINe... It may have been used for some birth controls, but mostly for menopaus treatments.

Whoops! We posted at the same time

Thanks for all the great info! All I know is she was from "Ranch 16". I tried to get more information with no result. She also has a large RJ on her left shoulder. The J is an extension off the R...any idea about that one?

Also, she was sold to me a Percheron Cross...I personally see Clyde, but whatever.

Opps, should of been 10,000.

Of the remaining ranches, the majority (over 50%) of the mare are quarter horse and another 25% are paints, appys and other light horses. That only leaves about 25% of the mares being draft. Percherons make up about 50% of that number. Wyeth, now Pfizer, is the only company in the business. They were the one that developed the drug. There was another company, Natural Biological, that was breifly around. Their mares were predominantly in the Dakotas, Minnesota and Wisconsin. They were shut down 8-10 years ago by Wyeth. The number of Wyeth ranches have dropped from a high of 400 to currently 26.


It must be the classic Clyde coloring that made them think "she must be part Percheron...." My money would be on 1/4 clyde 3/4 QH or 1/4 clyde, 1/4 TB and 1/2 QH.
Referring to the ranches by numbers was a way the rescues protected the ranches and horses from the zealots and the fallout from the collapse.
The RJ brand might actually tell you more about her than the 810. Can you tell if it was done at a different time? I would think that the RJ is where she is actually from. She was branded as a weanling. Ran with a bunch of other fillies, separated out as a 2 year old than sold as a replacement mare where she got the 810. Find someone who can check to see is she's microchipped. Should be in the neck about 1/2 way down.
