Abstract

The herd consisted of 25 captive Esfahan mouflons and their
offspring. The mouflons were wild and originated from their
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 have
suggested 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.
