over fertilization is a contributing factor but stress is a bigger factor.Nitrate test? Oat, harvested green, is a very nice hay here. Do people use that much chemicals in America?
Same here. I've fed oat hay occasionally and the goats liked it. Most of time I add alfalfa to their pasture feeding. I think the oat hay was a welcomed variety for them. It seems to be sweeter than alfalfa (We call that lusern here).I feed my goats oat hay, no issues.
