This study was carried out with two groups of bovines naturally infected with Boophilus microplus. One group was treated every week during a month with Neem's watery extract and the other group was treated only once (at the test onset) with amabectin pour-on. The results of the Kruskal-Wallis test showed no significant difference (P<0.0001) between both groups (Neem and amabectin) throughout the experiment. However, time of collection [(day0 = day15) <FONT FACE=Symbol>¹</FONT> day30] and age brackets (cows<heifers) showed significant effect. Neem’s watery extract was cheap and easy to prepare, even at farm and could replace amabectin in the control of Boophilus microplus in bovines.
