Just a little advice - quarantine a new horse regardless of where the horse came from for a minimum of 2 weeks as a precaution.  In spring and fall the grass changes levels of sugar - keep a close eye on your horse and their feet, digestive system during this time.  Don't forget to worm for bots after frost - and after proper de-worming schedule.  If you worm a horse with a strong  wormer without a proper de-worming cycle you can bind, colic and kill your horse.

A horse that is slaughtered immediately ceases to contribute to the economy. A horse that lives adds constantly to the economy. He requires food, a veterinarian, a farrier, a dentist, and people to care for him. The ripple effect of that living horse across the economy is huge. Hay and grain will be grown and bought for him; he will require medication and vaccinations; he will require a place to live, like a boarding stable. Money for the economy.

So.... What is going on?  State regulations shut down the US Slaughter plants.  However, horses have always been exported to Canada and Mexico for slaughter for human consumption and they are looking to open slaughter houses in the USA AGAIN and it happened 11/11 language was removed to allow the USDA to inspect horsemeat in the USA.
