Study of degenerative Injury of Frogs (Thrush) in kurd Horses

Degenrative injury of the frog (Thrush) is one of the diseases of the locomotor system in horses and despite paying special attention to this disease. This study was performed in equestrian centers on Kurd horses. In this study, all four motor limbs of 384 horses kept in care centers were clinically examined. Factors such as age, sex and number of infected venoms were evaluated and the incidence rate was graded from 1 to 3, with grade 3 indicating maximum frog disease examined to see if the horses had a black discharge in the frog's cleft. From all the studied horses, 215 (55.84%) heads were diagnosed with the disease. The prevalence of most research samples is between 7 to 10 years of age, and the lowest frequency is in the range of 4 to 7 years (P <0.05). The incidence of the disease was not related to the sex of the animal and no significant difference was observed (P <0.05). Transformed frog disease in the anterior motor limb of the studied horses was significantly higher than the posterior motor limb (P <0.05) and grades 2 and 3 of the disease in the anterior motor limb were more than the posterior motor limb was observed. Among the studied samples, 120 cases of anterior limb involvement and 95 cases of posterior limb involvement were observed. The quality of the litter, the use of moisture-absorbent litter for horses, improved nutrition, and regular venom modification can protect against poisonous frog thrush and improve performance.
