Preliminary field investigations revealed the presence of Cooperia pectinata,
C. punctata, Haemonchus placei, Oesophagostomum radiatum and Bunostomum
phlebotomum as the most common parasites of bovines in the North Western Cape.
Experiments on the ecology and epizootology of these parasites were carried out
under field conditions, at the Armoedsvlakte Research Station near Vryburg in the
North Western Cape.
Possible methods of prophylaxis based on experimental observations are
described, and the possible use of strategic drenching, using anthelminthics which
gave promising results, is included.
