I add Alfalfa pellets/cubes since they hay we can get locally is a orchard grass/clover mix only, and since none are ridden or worked, I keep with the 1.5% body weight, but the mare is in foal, but only 4 months, so I haven't upped her feed yet.
The Clyds mix looks fantastic, as does the pony and filly, and the Clyds was an emeciated rescue a few months ago, but the Saddlebred and Arab are looking underweight - Body scores of 4 and 4 1/2 per the vet. . . but they are both hard keepers and even in the summer on full pasture, plus the above feed and added hay, stay that way - BUT I just have their teeth done, so I am hoping for an improvement with that - I've only have the Saddlebred rescue since May, and the Arab is our broodmare, and we've just had her since July.
