Hi I have posted to this forum before after I had rescued a 17 year old Arabian gelding. I put a lot of weight on him by using shredding beat pulp, calf manna, vegetable oil, weight builder, and he is on equine senior. He gained weight steadily but now he has started losing weight again. His coat is getting duller but that could be because it's starting to grow into winter (it's just that my mare still has her summer sleek coat) I understand that every horse is different, and I'll be honest I have no experience in Arabians, but I can't let him widdle away. Also I have done blood work on him and everything is normal. What about max e glo? With my work schedule I feed him in AM and PM. Ugh anything?
1. He's a rescue, was he checked for ulcers?
2. Is he on a high quality probiotic? Again, he's a rescue and he's 17, his digestive system could use some help in the microbial department.
Three of my horses are on "Probios". My 27+ Arab has been on it for several months and it's the only thing that stopped his loose stools.
3. What kind of blood work? A FULL CBC? If not, I know it's expensive but a full CBC should be done.
3.1 Are you sure it isn't muscle mass he is lacking more than fat? A crucial thing because that's where a full CBC would come in handy to check for something called "Malabsorption Syndrome".
This seems to be something that, while not common, also isn't rare, and that Arabs seem to get. Gastrointestinal: small intestine - malabsorption | Horses | Vetstream
I am waiting on the results of a CBC, as I write this, on my 27+ Arab. He consistently has 3 of the 9 indicators. Two more indicators intermittently present themselves.
The vet gave him a thorough hands on and is reasonably sure cancer isn't involved.
She said what teeth he has left are "amazingly good".
She said he has enough fat but the lack of muscle mass is a concern and is what makes him look so poor. That's why I asked if you're sure your Arab might be lacking more in muscle than in fat
His coat is so slick, I could find him at midnight without a flashlight. Healthy hooves.
No indications of Cushings which, by the way, thin horses can develop. Was your horse tested for Cushings and other metabolic issues?
Even though I gave the vet a detailed list of what the Arab eats, she doesn't want to make any changes until the blood tests come back.
My fella is 13.3H. He's on pasture all day, in at night with at least ten pounds of the fluffiest hay I can dredge up (four missing molars). Unless I hit on a "prime rib" bale of hay, I'm lucky if he eats 20% of what I give him, every night
I feed him three times daily. A daily total of ~12 pounds of roughage, Senior Feed and rice bran go into his feed pan.
I'm not saying your Arab has a protein assimilation issue but, if you're feeding him an ample amount of everything he's supposed to have for his height and desired weight, including forage, it's a possibility and so are ulcers
