Very interesting...I too use mainly Zimectrin (ivermectin) based
wormers...will ask vet about that for his opinion.

Now this is also a possibility with this particular mare here...she
does not
have Cushings, but is the one who receives more than a handful of grain,
compared to the others. She is older and has had the most medical-related
problems. She is on thyroid meds. and has low progesterone also (trouble
conceiving and keeping a pregnancy). All these things could be related
somehow.
