STUDY ON PREVALANCE AND THERAPEUTIC MANAGEMENT OF ECTO PARASITES IN CATTLE AT KAUNIAUPAZILAIN RANGPUR DISTRICT

Abstract

The study was conducted to investigate the overall prevalence of ecto-parasites in cattle in relation with age, sex, breed and seasonal variation and the therapeutic effects of commercial drugs against tick, lice and mite. A total of 790 clinical cases were registered for the clinical diagnosis and therapeutic purposes at kaunia upazila veterinary hospital in rangpur district of Bangladesh for a period of one year from July, 2016 to June, 2017. Diagnosis was made on owner’s statement, general examination and clinical signs and response to treatment. The overall prevalence of ecto-parasites were 25.6% of which the highest prevalence was lice 12.78% tick 7.59% and mites 5.18% respectively. On the basis of age >3 years the highest prevalence of tick 9.1% and lice 15.86% was seen in above 3 years age group and mite 6.67% in 2 years to 3 years old. According to sex the highest prevalence of tick 8.5%, lice 14% and mite 5.5% was found in male then female tick 6.67%, lice 11.54% and mite 4.8%, animals and breed-wise 8.81% tick, 17.86% lice and 6.43% mite was recorded in indigenous cattle. In respect of season, the prevalence of tick 11.67%, lice 17.5% and mite 8.33% infestation were significantly (P<0.05) higher in summer season then rainy tick 4.91%, lice 9.06% and mite 3.34% and winter tick 6.67%, lice 12.28% and mite 4.21%. Statistical results of the study also showed that the parameters breed wise prevalence by lice had significant (P<0.05) effect but age, sex had no significant (P>0.05) effects on prevalence of tick, lice and mite infestation. Animals treated with different ecto-parasitic drugs showed significant (P<0.05) effects on their date of recovery. Subcutaneous injection of combined ivermectin and clorsulon (Amectin plus®) showed quick result of recovery than single ivermectin (Vermic®) S/C injection and Ivermectin pour-on therapy against tick, mite and lice.
