I think it also depends from horse to horse. Like humans, some seem to be more delicate than others (hell, I knew a horse allergic to hay). We spent two winters in arid areas of Spain where Kaylee ate plenty of the small local acorns (from spiny evergreen oaks), also with no ill effect. These tasted exacly like dried sweet chestnuts (I tried them). Here we have tall deciduous oaks with large acorns, which are also fine (although bitter).
Just sharing my experience, here. But in Germany they say that Hafligers can eat anything, and grow fat from it.
