dc.description.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. | en_US |
