The issue is simple - supply and demand with no realistic market for culls. Horses are livestock. Livestock is stock. Stock needs to have a salvage value to be profitable.
When the market was good, there was a demand for horses. When the economy crashed, no one had money for luxuries (aka horses) anymore, so the demand stopped, the supply didn't. Somewhere in that time frame horse slaughter then became illegal and effectively shaved $600 off the price of every horse in the country in the process. Instead of Fluffy going to the plant and maybe one or 2 auctions first, Fluffy now goes through auction to auction to auction where he eventually ends up in Backyard Billy's Barnyard after being sold for $50 where he eventually just withers away in the back 40. Horse's dropped in value hard and fast because of the lack of 'salvage value.' it might be blunt, and this probably isn't the thing to say to a group of horsemen - but bringing back horse slaughter would not only provide more food for the nation, but would increase the price of horses, stop the market from being so flooded, and therefore the price will eventually turn around.
I am a dairy farmer. I ride the market for a living. My market swings MUCH more than the horse market, and instead of a hobby it is a business that supports 6 familes. In 2009, when milk hit an absolute 'why even bother' price, we lost money. We knew we were going to, but the truly excellent farms got through it. This is maybe the Miniature horse world's '2009,' the best will get through it, the rest will go out, but regardless, it WILL turn around someday. Dunno how, but have faith!
I agree with Doctor Taylor 100% - the main cause of dystocia is human error and poor choices with breeding! I disagree with confinement on heifers though - 4 years of college and a Dairy Herd Management degree later I have still never even heard of that. My girls are in 'confinement' housing in a freestall - and we have to pull maybe 3 to 5 a year out of 800 or so calvings. The reason for that? Healthy, properly conditioned animals and GENETICS. In cattle, pasture is not needed to effectively manage them and keep them healthy, they are not horses though and horses are a TOTALLY different story.
Here, all animals are bred to Bull's that have a less than 93% chance of having calves that need assistance to be born. Heifers are bred to bulls that have less than a 95% chance of a rough calving. All bulls selected have a +1 or greater DCE score, or daughter calving ease, meaning that their offspring will be small as calves, then grow to be ladies with 'good birthing hips.' However, the cattle industry is FAR more advanced in terms of genetics and reproduction as opposed to the horse industry. We don't have those numbers on stallions because their get is not scrutinized and studied like cattles are, they don't have the volume of offspring cattle do to come up with reliable numbers, or even a way to determine a stallion's produce value that's not 110% subjective.
It's all based on show winnings, a judge's opinion, or our own personal opinions on how his 'babies look' - and in the process of that we end up with DUDs. Its a fact of life, when stud companies test bulls we get DUDS, but because of genomics ( an emerging technology that maps the genome and correlates amino acids sequences with genetic traits ie an adenine here means he will probably sire posty legged offspring ) we are getting less and less. But in cattle, we sell those duds for beef after we milk them awhile and just don't keep her calves. There is a market for those culls. In horses, we try to pass that dud along to the first sucker that will pay cash for it, market it as a 'real nice horse,' and they take that dud and breed it again, making more duds for the next sucker to buy, flooding the market and driving down the price of even the nicest horses because of it. There is no realistic market for these culls.
Do all breeders do that? No. Does everyone who gets a dud breed it until it can't anymore? No. There are a LOT of really good, really responsible breeders and homes out there that we often forget about. We should take a moment to recognize them instead of always griping about Barnyard Billy. It's really not all that bad out there! First world countries are the only ones that geld and spay their problems away, but the only ones with overpopulation problems, therefore its OUR fault! however, its no more Barnyard Billy's fault for pumping out dwarfy unregistered critters than it is Showring Susy's for selling her duds - it all boils down to an over supply and an under demand. One of the two needs to change. How? Don't ask me. But I think the VERY first step is to stop pointing fingers at either side, and to come up with some kind of realistic market for culls.
