Well, my horses are doing amazing on the Purina Ultium Gastric care. Just found out tractor supply is no longer going to carry it and all of the dealers within 100 miles are not carrying it because it doesn't sell as well. :(  ALl local places want me to order a pallet minimum.. No way. LOL SO I ordered it online from NRS. Expensive to have 50 pound bags of feed shipped but I'm not giving it up. First TX shipment will be here monday. Is there any mills I need to watch out for in TX? Just being over cautious. THanks! 

I dont trust Cargill feed mill at all here in Seguin, texas, I know that they mill for Nutrene, but dont know about Purina, but pretty sure they do. I had a beautiful colt that I traded a gelding for and the lady used Nutrene feed and was milled here in town well, about 6 months into having the colt this lady went threw hell because the feed was tainted with some cattle med and this colt got really sick and had to be put down, he was tested befor he was put down and came back postive with some type of cattle meds, I cant remember what since this was about 10 yeras ago, but this feed was milled at Cargill here in town {Seguin}..there was a law suit, but cant remember how it turned out.

Have you checked with Chewy.com to see if they carry this feed that you are using?

Its the Purina Ultium gastric care. Chewey does not carry it. I will for sure check my tags on the new feed when it gets here to see if its from the Mill you listed! thanks so much!
