I am sorry to say this and don't get me wrong I am not saying you don't know what you are saying but all 5 of the horses I had before I got while underweight and I tried doing the free choicing thing in order to save me time easement and stregnth but it did the oppositte 3 of the 5 (which were Paints also) ate to much when I got a vet out there he said they were bloated because of this reason. He told me only so many horses actually know when to stop eating most will just keep on eating and eating mainly because nobody trains them for that. Trust me I am not trying to say you don't know what you are talking about but I learned this from experience. I belive it may because of the hay we get up here it isn't like what I have seen in other areas (not bad or anything just diffrent) By the way thank you for calling by my name and not my username I appreciate that not many people do that.
You seriously need a new Vet.
Goats bloat, dogs bloat, cows CAN bloat though rare.... a horse does not bloat. Get a hay belly or get fat yes.
The absolute BEST thing you can do for an underweight horse is free-choice, good quality hay.
Heck, even my COWS have free-choice hay and nobody is bloating. Even the bull who my kids thought was stuck because he hardly ever removes his head from the round bale feeder.
Even if you insist on not free-choice feeding 1 1/2 - 2 flakes a feeding is not enough. When my 14.2hh guy was underweight, we gave him 4 flakes 2x a day, checked on him at noontime and if he was low/out, threw him another few. He's a tad fat right now so he got cut back to 3 flakes 2x a day and another 1-2 at noon.
Agreed, my horses are either on round bales 24/7, or get at least 3 flakes per feeding if they are stuck inside. And if you are truly concerned about bloating (which isn't the same as bloating in other animals) a cheap once a day probiotic will take care of it.
The very first thing most rescues do when they bring in an underweight horse is give it as much hay as it wants. That is the best and quickest way to get weight back on. If your vet doesn't know this, I question just how good a vet it really is...
Tequila actually looks worse now then when you got her, you really need to up their feed.
My two horses were getting between a bale and a bale and a third a day. Approximately 60-80 lbs of hay for two horses. Currently they are on free choice round bale (with a slow feeder net) and while they are a bit chubby neither has had any issues with free choice.
If you don't change something with your management style you are shortly going to have three sickly and very thin horses (Tequila already looks there). It's easier and cheaper to maintain their weight then to let them get emaciated and try to put weight back on them.
Please take a look at this link, it'll give you some guidance in determining whether your horses are a truly at a healthy weight.
I'm jumping on the "Get a new vet ASAP" bandwagon as well.
Tequila needs A LOT more food (my boys get around 8-9 flakes[50ish pounds] a day each.) Granted, they are drafts, but still, 4 flakes in a day won't cut it. Tequila is not half their size. Up her food! The brown horse looks to be a good weight, to me at least. I'd try and get the pali eating more too. It looks kind of thin to me.
I'm glad you guys found a possible cure for the cancer, hopefully the new vet (THAT YOU NEED) can actually help and come up with solutions without your dad having to find things out via the internet.
I know this is a bit of an old post but I thought everybody is telling you that your horses are skinny but they don't show you what a good weight looks like. I thought I'd show you a couple of pictures of overweight and decent weight..
Here is Bucky (Norwegian Fjord), quite over weight.
Kid (3/4 Arabian 1/4 QH), fat! You can see how big his belly is and how thick his neck is.
Red (reg QH), he is over weight.
Zayn (1/2 Arabian 1/2 QH) he is in good shape in this picture. Not too over weight and not too skinny. I was riding him at least four miles every day.
Sarah, (grade palomino), in good shape. She was also being ridden at least 4 miles every day at this time.
All our horses have always had all the hay or grass they could eat. Never had a 'bloat' and they just got a bit chubby if we didn't work them.
Your horses I think all look good weight wise, exept Tequila when we got our rescue horse he was a little thin so we gave him corn oil which help a lot so you might want to try that plus it make their coats look shiny and healthy.
Do NOT feed horses corn oil; it can be very bad for them in excess amounts. There are much better oils, feeds, etc. out there to get them GOOD fats. You're better off upping their hay or giving them more of a quality feed than to do corn oil.
That horse shouldn't have one rider til it gets more weight, let alone two.
