I recently purchased a small tub of Probios powder to be used in Reno's feed, as he's been having diarrhea on and off since coming to his new home last December. It was never anything worth considering a major health issue as he always ate, kept himself hydrated, was properly wormed, good gut sounds, etc. At the worst it just annoyed everyone who does the horses' stalls (myself included). Apparently he didn't eat his breakfast yesterday morning (the first day with the Probios) and I didn't stay long enough after the unicorn birthday party to see if he ate his dinner. I'm sure the BO would call me if there was anything really wrong like him refusing to eat every day (besides grain he has free choice hay and pretty decent grazing all day even for this time of year).
I'm wondering if there's anything else I can suggest to my BO to make this addition more appetizing to him. To anyone who doesn't know, Reno is a coming 5yo TB gelding. He's a generally easy keeper.
