What I don't understand is..
Wouldn't the not-starved, hydrated, semi-healthy horse yeild a higher-quality meat, therefore creating more profit, so incentive to treat the horse better? And also, keeping them in better condition would decrease the number of dead animals, in turn increase the amount of meat per shipment of horses.
Growing up, we would feed out a steer or a hog to eat and that thing was always fed and watered.
I guess the world is an illogical place.. Which would explain why people want slaughter eradicated in the US only for the US horses to be shipped further and under more strenuous conditions.
