That is exactly why I had all of the fields completely tilled and completely re-seeded with a mix that had certified tested fescue seeds. Then did the re-testing. I don’t even have pregnant mares, but I didn’t want to run into that issue down the road. Also yes I completely agree with the time. We always used to make sure that we cut our hay early morning. I’m thinking about sending in a soil sample to Logan labs here for mineral content too. I asked if anyone in the area had any issues with selenium poisoning (because of the studies I read about it happening more commonly in the Midwest). They think I’m crazy I guess? Everyone here seems to just feed the pre-mixed feeds. I was looking at the labels at the local feed store and some of them were pretty high in selenium which is great if your soil is low in selenium, but not if your soil is high. Although I even was told to “just feed sweet feed to keep the yearling weight on”. I might as well just bake my horses a sugar loaded cake at that point

I’m still having my soil tested for selenium levels. I noticed a lot of horses around here have brittle hair and hooves which could be many things, but I still have my selenium toxicity concerns. Based on the US soil data map our area is on the high side. I am a big Dr. Kellon fan I have been reading her work and articles since I was 13 and now I’m almost 30
