Kentucky's ongoing attempt to end racing in state proceeds..

The origins and causes of EIPH are thought to be multifactorial. In the 1990's I worked on the research that first measured actual cardiopulmonary intravascular pressures in horses while galloping at racing speed both on and off lasix. Lasix decreases the exercise-induced increase in cardiac and pulmonary pressures. High blood pressure rupturing fragile capillaries in the lung has always been one suspected cause of EIPH.

Chronic airway inflammation predisposing to capillary failure is another. I'd love to study the lungs of horses that live year-round at Churchill Downs, bordered by highways and under airport plane exhaust.

Another is the physical pounding, and physics: the sheer forces created within the lung tissue as a horse gallops a long time over firm ground carrying weight.

Another is the huge variance in intrapulmonary airway pressures, upper vs lower, during massive air intake of exercise - why the Flair nasal strips which hold the upper airway open decrease EIPH as much as lasix in some horses.

Speaking of pollution that the horses are breathing, I know that it would be expensive but wouldn't it be much better for the horses' lungs if the barn areas were re-done at all the tracks. At most tracks, the whole barn area is dirt. Why not put grass down everywhere and then pave the paths with that rubber brick stuff. Inside the barns, they could put down that rubber brick surface too.

I would have to think the horses would be less likely to bleed if their lungs weren't filled with all the dust that they breathe in all day in the barn area.

At Oaklawn Park they have a lot of grass in the barn areas. I would have to think that is much better than all that dirt and dust.

Horse airways are designed to work with the horse's head down in the clean, green grass, grazing.

Most non-racing barns feed hay on the ground for that reason. Tracks determine if a trainer can use straw (can have alot of molds) or shavings to bed. Off track some people use newspaper or simply rubber mats for bedding allergic horses.

Yeah, horses inhaling all that dust from gravel drives and dirt on the track isn't as good as not doing it.

Those pavers are high dollar items.

Hey - for a mere less than 2 million, you can purchase this place next to the TB Training Center in Lexington, and have all your horses out getting grass time daily!
