Getting rid of DSLD-ESPA (horses that is)

Hmmm, a couple more links:

http://www.topix.net/forum/city/eubank-ky/T0D2905NHMTM83DHU/p2 (scroll down to last post)

Could this be a trend? Note on the equine rescue website it states:

Crimson was donated after developing Degenerative Suspensory Ligament Desmitis (DSLD).

And here's a quote from the second link:
The breeders in Peru would cull horses that had any defects by shooting them. They would not sell them or even give them away because they did not want these faults in either gait, confirmation, or temperament passed down. Breeders in this country get rid of their culls in a different way, they sell them to some unsuspecting person. At one time I thought the Peruvian Pasos were probably the safest horse to buy. I have changed my mind completely though since DSLD is very common in the Peruvians now.
