The study of infection rate with strongyles in the horses of Shiraz and it's suburbs regarding to age, sex and method of feeding.

In this study the faecal samples of 100 horses belong to Shiraz and it’s suburbs were examined for the infection with strongyles. The faecal samples were collected directly from the rectum of horses and were put inside the lidded plastic container and transferred to the laboratory. The faecal samples were examined by floatation method. Diagnosis was based on the observation of strongyle eggs in microscopic examination of faecal samples. 68% of investigated horses were infected with at least one species of strongyles. The difference of infection rate between different age groups and also male and female horses was not statistically significant but the infection rate was significantly lower in hand feeding horses in comparison with grazing horses (p<0.05).
