Wait - you aren't allowed you supply our own Hay Bag? I don't like Hay nets either, but a Hay Bag is nothing to be worried about.
What you can also do, this is what I do for Nelson because he's a piggy with his hay - is I got one of those huge plastic barrels and had it cut 1/4 off the top.
You can sorta see it here:
Although it doesn't look it - LOL - it does help keep his hay limited on the floor, which minimizes the amount that gets "trompled" on.
You might give that a try.
I have a TB and yes, many of them are hard keepers. The first and foremost should be roughage. If your barn isn't putting round bales infront of their faces out in their pastures/paddocks, and not giving unlimited hay to your horse, then I would look to go else where.
Your horses health and weight is foremost important. I was at a facility where they BO was not concerned about his weight, but more concerned about her pocket book - and due to that he lost 300 pounds.
I moved him. Enough was enough.
Sorry, but 6 flakes in a day is not enough, not even close to being enough roughage for a 1000lb - 1100lb horse.
Pasture this time of year, is ****. There is nothing in it anymore
Grain, should be just top dressing in accordance to the hay. Nelson has a round bale infront of his face out on turnout, and when he comes in at night, he gets 6 flakes of hay thrown into his bucket. He has hay infront of him 24/7. Very important.
If I were you, I would go to a Senior Feed. It is great for any age of horse because of everything that is in it.
What Nelson is on, is 8 pounds of Tripple Crown Senior. 4 in the A.M and 4 in the P.M
Which also comes with Shaved Beat Pulp, Bran, Ultimate Finish and Coacoa Soya.
He went from being ribby and very skinny *ask Spyder and Joshie, they saw him* to a very plump, in shape, hard to keep, TB.
