Abstract

Introduction: Trypanosomosis is a bottle neck on the livelihood of farmers in study area and 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 any information on effect of this chemical on prevalence of Trypanosoma.

Objective: The aim of the study was to evaluate the effect of Deltamethrine in controlling Trypanosomosis.

Methods: Cross-sectional study was conducted in 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 SPSS Statistics version 21.The approach followed to complete the study was by implementing pre-intervention phase to know status of Trypanosoma before using chemical in April 2020 and 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 prevalence difference.

Results: Out of 576 cattle during pre-intervention 159 (27.60%) cattle were positive with mean packed cell volume 20.68%. During post intervention Out of 576 cattle 27 (4.70%) cattle were positive with mean packed cell volume 26.10%. From study there were strong evidence at 95% confidence interval (t = 3.035, p < 0.05) Delthamethrine chemical application reduce prevalence of Trypanosoma parasite by ten estimated mean. Also there were strong evidence at 95% confidence interval (t = -84.66, p < 0.05) Delthamethrine chemical application increase packed cellvolume of cattle by five estimated mean.

Conclusion: An intervention was encouraging to suppress Trypanosomosis prevalence and should be continually implemented to keep the intervention difference.
