I remember when they would take truck loads of foals from the PMU farms down to Florida. I knew several people who rescued them, and they definitely were not in good condition! Some came in needing to be bottle fed, others were in poor shape, with rainrot covering them head to toe. They would get off the trailer barely able to stand, and absolutely traumatized.
I did have pictures, but nothing on my current computer.
They did make lovely horses with some nursing and specialized care. I was very glad premarin became less popular due to the health risks.
I don't know how much they have "cleaned up" their act. Just because they are breeding better quality animals, doesn't mean the horses they have are treated well. Especially when farms are not allowing outsiders to get access to that information, or see the conditions of the animals.
I know some states have been pushing to make it illegal for anyone to take pictures of bad farming conditions, even if driving by in your car.
PETA may very well use outdated pictures, as it is difficult and even dangerous to go "under-cover" and get access to that information.
There is a local animal rights group who had to sue the University of Florida, as they refused to release any records of their "experiments". Once the records where released, it was quite upsetting, as the experiments they are doing with primates are nothing short of torture.
They have a treadmill research program as well. If the horses are not adopted out at the end of the program they are euthanized. They sometimes put down perfectly healthy horses for other reasons. One time they needed eyeballs for some research... You would think they have enough horses put down for health reasons?
I actually rescued a perfectly healthy mare from them that they were going to put down. They didn't even attempt to adopt her out, I just happened to overhear that she was going on the "cull" list. One of the vets that works there has rescued beagles from them as well. An Eleventh Hour Exclusive: Images of Horses Tortured Inside UF | Eleventh Hour for Animals
The above group does have extremists but given my experience with UF, what they have published is probably based in truth.
I have to believe there is a better way of doing research. Aren't there enough horses out there that are already crippled without needing to ruin perfectly healthy animals?
