Okay I have 3 horses. One 21 yr old hard to keep extremely finicky retired full arab mare (a babysitter who has earned her retirement due to arthritis).One 18 yr old morab mare who will eat ANYTHING not nailed down, but also a touch hard to keep. An 11 yr old pintabian (pinto arab) who is NOT a hard keeper and who will also eat ANYTHING. SO on the 16th I bought a 700# round bale from southern states that was fescue orchard grass mix and VERY nice hay.I had wanted to try roundbales to lower my feeding $$$. All 3 LOVED it, even my finicky old mare.It only lasted 8 days. It was $40.00 which is high but it was because it was from Southern states not a farmer. I also bought from a farmer square fescue hay $2.00 a bale. It IS horse quality baled this year. They will eat it when in but obviously it does not compare with the fescue/orchard grass roundbale. I was/am feeding my guys southern states legends high fat (9%) pellet.I HAVE to have a high fat pellet for the old retired girl. So my dumb question is has anybody been able to keep their horses fat and sleek on nothing but hay, paticularly roundbale hay? I would like to just feed the younger 2 the good quality roundbale hay and the retired girl a smaller ration of the high fat pellet. I was told they would waste a lot of the roundbale but I only had about 10% wastage.I have NO grass and they live on rocky soil.So the hay keeps them busy and happy.The 2.00 square bales are fine for when they are in, but I doubt they have a lot of nutritional value.My old girl picks thru the square bale hay. My guys ONLY go in when it is cold and wet, they stay out most of the time.That is because the old girl will PACE in a stall if you just do 12 hours in 12 hours out.SHE wants to be out unless it is cold and wet, and she will let you know when she wants IN by pacing at the gate. So I would like to get a roundbale every 7-10 days and then just give my old girl a grain ration.Has anybody had any luck with this? I have had horses for over 25 years but never tried the roundbale thing before. I could not afford to give them all they could eat quality square bale hay, but even at 40.00 the roundbale WOULD cut down expenses if I could reduce my grain rations for the 3. So anybody have luck keeping horses fat on JUST quality roundbale hay?
