I board my horse where he is in a group of about 12 geldings. In the larger farm, there are another 30 or 40 horses on 300 acres.
The horses are brought in once daily. My gelding gets Sho Glo for minerals and half a handful of horse feed. He is an easy keeping Morgan who looks great.
A couple of weeks ago, I noticed that he had runny poo and mentioned that to one of the barn staff. Staff guy said that it might be because they had started all the horses on aureomycin to combat winter colds. He said it has been very successful in the past.
Since that time, my horse’s poo has returned to normal but I feel uneasy about the antibiotic - it doesn’t appear to be harming him but theoretically, his gut biota might be harmed and the bad bugs might become antibiotic resistance.
Should I quit worrying because he looks and acts just fine?
