This study focused on finding out the impact of immunization of cattle against ECF. Although there were other methods of treatment, this study specifically looked at Infection and Treatment Method (ITM) of immunization against ECF. The study considered a time scope of nine years (2007-2009). Farmers were improving their cattle production and productivity. ECF was however a limiting factor towards achieving their ultimate goal.The objectives of the study included establishing the effect of ITM on ECF prevalence and mortality of cattle. The study found out that the vaccine was imported by government and delivered to farmers via government extension system. The prevalence of ECF was reduced and overall crude mortality due to ECF in cattle was reduced.Farmers should be sensitized and encouraged to adopt ITM as its advantages were demonstrable in improving production and productivity.
