Changes in the presence and distribution of several globally important parasitic infections of sheep might occur as a result of an increase in global trade and climatic changes. And with increasing reports of parasites resistant to all three main anthlemintics the viability of small ruminant industries is under threat. Vigilance, and refinement and development of parasite control strategies are essential to ensure viability of sheep production.
Changes in climate could lead to substantial shifts in the distribution and importance of particular parasites,
Increases in temperatures could result in lengthened fly activity resulting in a higher incidence of strike.
