These pests cause obvious discomfort to livestock and economic effects of heavy populations usually are discerned easily. However, research efforts to date have failed to establish reproducible losses caused by specific ectoparasites. Research efforts involving a multidisciplinary systems approach are necessary to provide the data needed to develop total dairy management programs.</style></abstract><issue><style face="normal" font="default" size="100%">11</style></issue><notes><style face="normal" font="default" size="100%">LR: 20031114; JID: 2985126R; ppublish</style></notes></record></records></xml>
