is it safe for him to gain so fast?

Here is a picture of when we got him (december 31st)


And this is what he looked like a month later (end of january)


He has gained a total of about 110 lbs (this is by weight tape so not the most accurate) from the 31st of december- yesterday.

Is this safe for him or should I lower his amount of feed a bit?

I don't think he looks like he's gaining too fast. The skinny ones I have had put the first 100 -200 lbs back on fast and then the rest seemed to go on slowly. I've got a skinny one now I'm feeding and that last 100 lbs just doesn't seem like it wants to come but she is steadily gaining so I'm sticking it out. I was able to see a difference in a month but a lot of it was in attitude. With good food the world became interesting again. Made her carry herself a little different. Hard to describe but with a full tummy it lifted years off her.

No weird ridges on hooves or anything? Lots of good clean hay and a nutritious meal. Does wonders.
I see a shine in his coat that isn't there in the first pics. Keep on like your doing.

He looks a lot better,as Sue said-lots of good quality hay-maybe you've wormed him? He looks young, so he may have a growth spurt also, at some point. Keep us posted - the forum has so much knowledge,so don't be afraid to ask.

In following a variety of very emaciated horses from near dead to fat and on a diet, I can say that there doesn't seem to be a limit to how fast weight can be gained. Of course, in the beginning you have to be careful to avoid Refeeding Syndrome, but after that, no worries.

For instance, Grace, the horse in this article [prepare yourself for a VERY skinny horse, not pretty]:
Pet Talk: Grace, once 400 pounds underweight, gains pounds and Facebook friends | OregonLive.com

She started out 400lbs underweight and 90 days (3 months) after her rescue she was up to a proper weight:




Your guy is looking much better already! Keep up the good work. He's going to look great once he shed out and gains a little more. :)

Yea im quite proud at what he looks like now. He has been wormmed and according to his lip tattoo he is going to be 15 in april. So he's not young. He's quite happy and actually has the energy now to come running at dinner time. Complete different horse now. Glad to hear he can't gain to fast. I was just thinking of some hoof issues that might arrise (other then the ones he has sigh) thanks guys/gals. I will make sure to keep this updated with new pictures as well
:)

Here is his diet now (started him off very slowly)

Am
6lbs alfalfa
1.5 lbs strategy healthy edge
Couple apple treats :)
1 scoop cool calories 100
All you can eat local grass hay

Pm
6lbs alfalfa
1.5 lbs strategy healthy edge
1.5 lbs beet pulp
1 scoop cool calories.
Couple more apple treats :)
Fill up on local hay for the night.

OMG LORD HAVE MERCY that poor girl!!!!! How was she still alive? I shivered when I saw my boy before brining him home, I can only imagine walking up on a horse lookign like that, actually it so bad I don't think I could.

I know, right?!
Grace was in her mid-late 20's when they found her like that so it was extra awesome that she was able to recover. I had linked to a page showing what she looked like recovered but it was apparently removed due to being from Facebook.
If you want to see (and you have a Facebook), look up "Grace - the little horse with the big spirit" on FB and you'll see her looking (and acting!) fat and sassy.

Sadly, she died a few months ago from colic due to the rocks and sand that she ingested, while she was starving, trying to keep herself alive. :(

Anyway, that diet looks pretty good! I bet he's loving all that food!
You could probably even bump the beet pulp ration up a little more if you want. It's really great for putting the pounds on while being low in "the bad stuff".
I know that when my super easy keeping mare is looking "skinny" (aka "less fat" ) I'll add a pound (or two, when the weather tells me she'll be burning even more calories keeping herself warm) of beet pulp to her daily ration and she's back up to weight in no time. 3 pounds of BP probably wouldn't do anything but help your guy. :)

About the Strategy, are you feeding him the correct amount of it for how much he weighs now or his estimated healthy weight? I've heard that for for underweight horses, you want to be feeding them the feed ration for their healthy weight vs the weight they might be at now. So if he'll weigh 1200lbs healthy, you want to feed him the 1200lb ration of Strategy.
Of course, if you are feeding him for his healthy weight, ignore me! :)

When it gets really cold I give him 3 lbs of warm beet pulp at night. I was guessing his healthy weight to be about 1100, I have realized it all depends on the horse what there healthy weight it so I figure if we get to that weight and he still looks like he needs more I will add the extra (and im sorry I feed him 1.80 lbs per feeding not 1.5 lbs so 3.6 lbs per day) So according to the purina website im feeing .1 lbs to much, oh well its for extra yummy lol.

Poor baby girl, she sure was a fighter. Here is he facebook page Grace - the little horse with the big spirit | Facebook

She sure did turn out to be a very beautiful old girl. I need to find out what super food they were feeding her lol.

Coming up with a few more pictures from the first day we got him. Also his name is Kona (figured you guys would like to know) his registered name is slewed jury.
