Introduction
Trypanosomosis is a bottleneck on the livelihood of farmers in the study area and the Ethiopian government has been using
0.4% Delthamethrine impregnated targets and 1% pour-on to reduce the impact of this disease on food security. However,
there was no information on the effect of this chemical on the prevalence of Trypanosomiasis.
Objective
The aim of the study was to evaluate the effect of Deltamethrine in controlling trypanosomiasis.
Methods
Cross-sectional study was conducted on cattle of two districts of Buno Bedele Zone in April 2020 and 2022. Paired samples
“t” test statistic was used to summarize data by using statistical package for the social sciences (SPSS) statistics version 21. The
approach followed to complete the study was implementing a pre-intervention phase to know the status of trypanosoma before
using a chemical in April 2020 and an intervention phase using deltamethrine chemical on cattle at a rate of 1 mL/10 kg body
weight and 0.4% Delthamethrine impregnated targets from October 2021 to March 2022. The post-intervention was done in
April 2022 to evaluate the prevalence difference.
Results
Out of 576 cattle during pre-intervention 159 (27.60%) cattle were positive with a mean packed cell volume (PCV) of 20.68%.
During post-intervention out of 576 cattle, 27 (4.70%) cattle were positive with a mean PCV of 26.10%. For the study, there was
strong evidence at a 95% confidence interval (t=3.035, p<0.05). Delthamethrine chemical application reduces the prevalence
of the trypanosoma parasite by ten estimated mean. Also, there was strong evidence at a 95% confidence interval (t=-84.66,
p<0.05) that Delthamethrine chemical application increased the PCV of cattle by five estimated mean.
Conclusion
In both districts, there was strong evidence that deltamethrin chemical application reduces the prevalence of trypanosome parasites. Deltamethrin chemical application increased cattle’s PCV, which showed that an intervention was encouraging to suppress
trypanosomosis and should be continually implemented to keep the intervention difference.
