| Abstract: | In 1978, treatment and vaccination programs were recommended to control bovine trypanosomiasis and brucellosis in Ivory Coast. A single trypanocidal treatment of young calves dramatically reduced their mortality rate. A preliminary demonstration project was carried out in a limited area by the government agency SODEPRA, followed by demonstrations on nearly all the farms. The costs were covered by SODEPRA as one of their development projects. Over a period of time the farmers took charge of the treatments, both financially and physically. In 1992, the trypanocidal treatments were still widely used. The reasons for this success could be its dramatic efficacy, the simple technology employed, the low cost that was progressively charged to the farmers, and the fact that this was a long term extension project with continuous farmer training. The brucellosis control program started with an initial vaccination of 1 to 10 year old females followed by an annual vaccination of 1 to 2 year old heifers. One year later, a 37% reduction in the abortion rate was observed. The vaccination were paid for and carried out by SODEPRA. The control program then stopped but, because of growing problems with brucellosis, vaccinations started again in 1992. There is still a question of how vaccinations will be accepted when the farmers are required to share the cost for the control of a largely inconspicuous disease. |
