The Prascend is fed separate from meals in a cookie (which we will see if it continues to work, she is currently very unenthusiastic about it).
The Coolstance + beet pulp isn’t overly appealing lol but it is good for them. I feed Contribute fish oil which is very strong smelling (smells like bubble gum - it’s not new to them) which I think helps.
TBH this seems to be a seasonal thing - the one horse I’ve only had for a year but the other I’ve had forever and she seems to go slightly off her feed (eats some but doesn’t finish, still seems excited to eat at meal time though) in the spring and fall when the seasons change.
I’m stuck between TC Senior, Ultium GC, and Renew Gold. I only add the RG as it’s soy free which is part of why they get the Coolstance but I don’t know if feeding a small amount of a soy feed (small as in 1cup per meal which is usually less than 1lb/day) would be enough to cause issues.
