External parasite control in hill sheep

In this video Michael Gottstein, Head of Sheep Knowledge Transfer Programme with Teagasc discusses with Teagasc BETTER sheep and Signpost farmer John Joe Fitzgerald about the importance of dipping sheep for the control of external parasites.
The development of alternative methods of external parasite control in sheep has resulted in a dramatic reduction in the use of organophosphate and Cypermethrin sheep dip usage.
However the rise of both anthelmintic resistant stomach worms and also in the UK macrocyclic lactone resistance sheep scab mites requires sheep farmers to rethink the strategy of using injectable macrocyclic lactones to control external parasites such as sheep scab and lice.
