I DID READ that article in Western Horseman!! It was a really detailed, thought out, and comparative piece of writing. They visited several farms, and did not think it was an abusive situation. Horses are kept "differently" but all had free access to water, were well fed, in good condition, no holes or sores. Things were CLEAN. Big remarks at the end were about comparing the barning to older, stanchion dairy operation, just not what newer horse folks expect to see for horses. No abuse to be seen!! Excellent journalism on a touchy topic. Horsemen with horse keeping knowledge, viewing a situation for CORRECT information to report. They were not bleeding hearts who whine if a horse doesn't have a 14' x 16' stall with food 3 times a day!
However I don't think many folks saw or read the article, who didn't do western riding!! We bought some horses up in Canada in the mid-90's from a PMU farm. We also had heard "bad stuff" and I was very curious about what we would find. I found it quite like an old dairy barn as well! The manager gave us the tour, explained how things were done. No horses were inside in July, they are out on the range then. I found everything to be pretty nice, easy to clean with power washers for sanitation. Mares were inside for only a few months in winter, and with a choice of -45F outside there, I would go for the barn too! The mare we bought had done time on the line, half TB with great legs, in marvelous shape. Manager said the Company buying urine did spot checks and things had to be perfect. If they quit buying, you were in DEEP trouble with no income!!
I think the deluge/dumping of PMU horses came a few years after article, when the Company said they were cutting back production. Synthetics were taking up more of the Estrogen replacement market, and then the heart problem report came out about dangers of taking Estrogen after menopause. Lots of women just stopped taking anything and the market fell apart!!
Meat buyers in Canada had more horses than they needed to buy, prices dropped to almost nothing. PMU folks who quit taking care of the horses were dumping at auction in the States and then the bleeding hearts uproar started. Of course I felt bad for the roughly treated Canadian animals, but it made me very angry when nice, BROKE animals locally could not be sold with everyone "full up" with PMU animals. Local horses who would have been ENJOYABLE to own and use, went cheap for meat instead of the PMU imports.
There was quite a bit of "no good deed goes unpunished" with the free, UNTRAINED, PMU animals hurting people, damaging property. Many were drafts and draft crosses,young animals turning into BIG horses with no respect for anything. Horses may not have had a purchase price, but they COST in every other aspect of having them around!! We lost potential long-term horse owners. They did not buy replacement animals when they get rid of the PMU animals because of all the problems they had with them. No fun owning such horses for many, huge expenses as well.
Our State of Michigan loses SO MUCH money with non-enforcement of various laws. Seems like there are plenty of enforcers for tiny things, but no one for big stuff like over-loaded semi trucks wrecking our highways, animals with no paperwork being introduced into the State. I would agree with you on organized horse activities following rules, having paperwork in order. But the folks who run down to Shipse on a Friday for the summer horse, don't have needed paperwork and NEVER get corrected, along with the killer buyers running home to Canada after the sale. Everyone just thumbs their nose at the laws and gets away with it. Heard about some out-west sale horses coming thru the Sales in Lansing just COVERED in ticks. New owner had to de-tick them when she got home. Who knows what those ticks had in them? Not inspected anywhere along the route and crossed a LOT of states getting here. Horses were lethargic, not enough blood left in them! Scared me, hearing about this. We got a free tick in alchohol for 4-H study, it was HUGE! And this is just stuff I know about, lots of horse things I would never hear of in other state locations.
