TOPOGRAPHICAL PREVALENCE OF LICE INFESTATION IN GOATS AT DINAJPUR SADAR UPAZILA OF BANGLADESH

Abstract

This study was conducted to identify topographical prevalence associated with the risk factors of lice infestations in 152 Black Bengal Goats at Dinajpur Sadar Upazila of Bangladesh from July to December, 2018. The results of the study showed that 46 goats were infested out of 152 goats by lice with the percentage of 30.26 %. The lice were collected through hand-picked and brushing methods. The collected lice were preserved in 70% ethanol. The number of lice were entered in Microsoft Excel spread sheet and analysed with Statistical Package for Social Sciences (SPSS) software version 22. Chi-square (χ2 ) test was used to determine the associations between age and sex with the lice infestation in goats. Female goats were infested with lice with higher prevalence of lice 23.68% (36/105) than male goats 6.58% (10/48). With regard to age factor, young goats 21.05% (32/72) were more susceptible to lice infestation than adult goats 9.21% (14/80). The predilection site of lice infestation was mostly found on the body region (73.9%, n=782), neck (19.8%, n=209) and head (6.24%, n=66) of goats respectively. Here, n=number of lice. Age, poor hygienic condition and poor living arrangement enhanced the transmission of lice infestation. Education to the farmer, routinely use suitable insecticide and cost-effective control strategies need to be implemented to minimize lice infestation
