Surveillance of cattle hypodermosis in district Chakwal, Pakistan

Cattle are mainly reared for milk and draught purpose in this region. An epidemiological survey was conducted to find out the prevalence of hypodermosis in cattle in district Chakwal, Punjab, Pakistan. Total 4000 cattle were examined clinically in the field (n=2000) and slaughter house (n=2000), for grub infestation in the study area. The prevalence was 35.50 and 23.50% in the slaughter house and field, respectively. Prevalence was higher in males than in the females. In slaughter house, it was recorded as 39.50 and 31.50%, while in the field 26.50 and 20.50% in male and female respectively. Highest prevalence (41.81%) was recorded in calves. Hypodermosis was recorded only from September to December, which suggested that change of climatic conditions in the study area favours the fly activity and contributes towards the onset of disease.
