Investigations to identify the causes of high mortalities in cattle in the
agropastoral zone (ZAP) of Yale started in March 1993. African animal trypa
nosomosis (AAT) was found to be the major constraint, with incidence rates
exceeding 30%, justifying a tsetse control programme, which started in Marc
h/ April 1994. The treatment of all cattle at bimonthly intervals with delt
amethrin 1% pour on and the display of 1500 insecticide impregnated targets
during the 6 months of the dry season each year helped to reduce the tsets
e populations (Glossina tachinoides and G. morsitans submorsitans) by more
than 90%. In less than 7 months, the incidence of AAT dropped below 5% and
remained there throughout the intervention until June 1996, in spite of an
increase to 3 months in the interval between the treatments. Mean PCV value
s increased significantly from 26.5-30.9%, before, to 30.7-36.3% during the
intervention. The improvement in the overall health resulted in a resumpti
on in fertility and milk production, allowing the sale of dairy products in
Leo, thus creating a gross income of about $US3/day for the Fulani women.
