The herd consisted of 25 captive Esfahan mouflons and their offspring. The mouflons were wild and originated from t heir natural habitat in Esfahan province. They had been kept in small enclosures with rough concrete floors. The diet consisted of alfalfa hay, corn silage, and a commercial concentrate. The mouflons showed severe claw overgrowth and detectable subclinical form of laminitis such as sole hemorrhage and yellow wax discoloration. Both prevalences were unexpectedly high (73.9%). The majority of foot lesion samples included in this study were taken from mouflons examined in the course of veterinary practice over a period of 4 months in a farm for clinical and histopathological purposes. Pseudocarcinomatous epidermal hyperplasia which are characterized by extreme proliferation of epithelial cells with large amounts of whorl-like structures that show no specific pattern, like dyskeratosis or central keratinization. Our findings were supportive of researchers who havesuggested that subclinical laminitis is a multifactorial disease that involves a complex interaction between nutrition and management. Feeding management, proper design of facilities and routine trimming seems to prevent subclinical laminitis is predisposed for more serious lesions in Esfahan mouflons.
