I don't know, it probably depends on the circumstances and outcome.
Like, when you sell a foal to have it living with people who want to sit on it's back, for sports, it would not be so problematic. (Obviously inspired by Ben's foal....
I watched a documentayr abot Haflinger this week, where they were breeding a high class version of this horse, and a good foal is just as expensive as a good car, like 50 000 €.
It's an intelligent, healthy and eager horse.
They say they WANT to learn and train new things so badly they get jealous of horses which are taken to lessons before them.
It speaks for the owners and trainers very much that the horses are enjoying their work so much they can't wait to go!
I think that's how it should be and how we should treat our winged and hoofed friends.
But a think the calf of a cow has another destiny and raising it---it's always exploitation for some species, Ausbeutung, and as such problematic.
Your thoughts, Hanzze?
