New rescue horse! Weight and worming!

I just got new horse for my little girl he is a qh and around twenty years old I was told. They guy who had him negelcted him and was really skinny, then he gave him to another guy who was able to get some weight on him but was only feeding oats and round bales. I was told guy number 2 was able to get some weight back, but he hasn't kept up with worming or trimming! He is just ribby in the belly, but his topline and hind end are BONEY!

First step I took is the vet will be out next week to float his teeth. I need to worm as well. I was told both good and bad about using a power pac on skinny horses, any advice? And I am slowing going to work him into a diet of soaked senoir feed, beat pulp, weight gainer supplement, free choice hay, and some green pasture.

Any advive?

I not familiar with the use of Power pac and its controversy but would like to know more if you could explain it
With some rescues here in Alberta the vet prescribed half the regular sized dose with ivermectin than 2 weeks later the regular full dose. This was to avoid massive die- off of worms that could impact the horse and kill it. For this case and those horses, Quest was too strong a product for the fragile state the horses were in. (I personally had my own old stallion go down after a quest deworming one time and never used it on him again to be safe). I know that in my area, Tapeworm deworming can be done in a later deworming, and should be considered due to tapeworm not showing up on fecal counts but still are present in the horses' system and be causing bleeding and impaction problems, hence poor health.
Good luck with your senior, it sounds like he made it to the right home!

I also noticed he has hay in his poop. Is it safe to say it is because he needs his teeth done and can't chew it or could this be more serious like a digestive problem?

We used a Power Pak on Bones when we rescued him. He was a 1.9 on the weight scale..We did get a blood test immediately, then wormed him as soon as we found out his organs were all functioning, just starvation causing him to be skinny

It's best to see what you vet has to say. It could be the horse is much older. In the mean time you might consider putting him on Seniors pellets and wet them until they are like wet grass. This he can eat if his teeth are poor. Senior's contains extra oils, probiotics for gut care and beet pulp for weight. Start him on 2lbs at least 2x daily, 3 x is better and work him up to no more than 5lbs per feeding. Give him all the hay he wants. Let the vet make the worming recommendations which he may base on a fecal count. The Senior's certainly won't do him any harm as it's a very safe feed.
