The trial also involved 42 smallholder dairy herds with 316 animals. The animals were clinically examined for trypanosomosis signs then screened for haemoparasites using blood smears and micro-centrifugation methods. Positive animals on smears were classified as “cases” and were treated with a curative dose (1 mg/kg bodyweight) of Kelamidium® and monitored for parasitological recovery on days three, six and nine. A total of six “cases” were encountered and five which were treated with Kelamidium® showed parasitogical and clinical recovery by days 3 and 9 respectively, whereas one animal died. Smear negative animals were randomly assigned to two treatment groups; with one group receiving a prophylactic dose (0.5 mg/kg) of Kelamidium® and the controls being treated with the same dose of Samorin®. These animals were then monitored clinically and re-screened on days 60 and 90-post intervention for re-infections. Kelamidium® showed a prophylactic efficacy of 99.4% and this was comparable (p>0.05) to that of Samorin® (99.7%). These results thus show that Kelamidium® offers an alternative choice to Samorin®.enTrypanosomosisKelamediumCattleHaemoparasites chemotherapeuticChemo-prophylactic*Article
