Bryony Poisoning

A local vet has reported a number of cases of bryony poisoning this year. Both white bryony and the unrelated species black bryony are poisonous to horses - and black bryony in particular is abundant this year, and not unpalatable to horses, especially if their pastures are well-grazed or over-grazed. As it is very fast-growing, you should check any hedgerows in your paddocks frequently for this dangerous weed.
