Mature cattle that have endured a drought can suffer weight loss if exposed to substantial numbers of larvae on pasture. The environmental life cycle is similar to cyathostomins, with the third stage larva being the infective stage.
Since the effective lifespan of most O. ostertagi L 3 is under 1 year and cross-infection between cattle and sheep in temperate areas is largely limited to O. leptospicularis, Trichostrongylus axei and occasionally C. oncophora, good control of bovine ostertagiosis should, in theory, be achieved.
