ABSTRACT
Twenty of 25 horses in a well-managed Missouri boarding stable were diagnosed with gingivitis/stomatitis. Gross examination of the affected horses revealed varying degrees of gingivitis ranging from mild periodontal swelling to marked swelling and erythema with ulceration and hemorrhage. Fine hair-like material was embedded within the intensely affected areas. Gingival biopsies from 4 affected horses contained pyogranulomatous inflammation with, in some cases, numerous eosinophils and several grass awns in cross and longitudinal section. Numerous foxtail seed heads were identified in hay samples. Examination of the records revealed that all of the affected horses had been fed the suspect hay, with the exception of 1 horse. Although not deliberately fed the suspect hay, this horse did have access to the hay when turned out into the exercise paddock. The lesions resolved following a change in hay source.
