Abstract :
Insect bite hypersensitivity (IBH) is a recurring and chronic allergic skin disease of horses. In the current research, the frequency of this disorder and also the role of some effective risk factors in its occurrence were investigated in horses of Lorestan province. For this purpose, during every visit to the horse breeding centers (between September 1401 and April 1402), almost all the available horses were examined for the presence or absence of skin lesions and the results were recorded along with individual information related to each horse and the environmental and management conditions of the place. The results showed that among the 383 examined horses, 74 (19.3%) were affected by this disease. Also, statistical analysis revealed that among host factors (including age, gender, breed, and color), the relationship between breed and the frequency of the disease was statistically significant (p≤0.001). Among the environmental and management factors, the location of sampling (city) (p≤0.001) and herd size (p≤0.01) indicated a significant correlation with the frequency of the disease. However, the relationship between the intervals of feces collection and the implementation or non-implementation of insect control with the frequency of the disease was not significant (p>0/05). The findings of the present study indicated that although the incidence of this disorder in horses in Lorestan province is lower compared to other studies conducted in Iran, the lesions caused by the mentioned disease have affected a significant number of horses in Lorestan province.
