Sheep Cydectin 2% LA working time.


New Member
Hi, can anyone tell me as to how many days after treating ewes with "Cydectin 2% LA" do the sheep stop itching?


If they have lice as well maybe never. If the scab is resistant to the treatment also maybe never. Does take a couple of weeks to stop itching if it works

The first time scab came here, the affected ones could not keep still at all. They were injected in the morning and by mid afternoon they were lying chewing the cud. I could not believe the speed of recovery.
I don't know what's changed but it does not seem to worry them nearly as much now, many years later.


If the bunch are resistant coming in they wont. They will then reinfect those it does cure initially in time.As you don't know which are not resistant coming in its a problem . We have had to dip all bottom sheep now.We buy a lot in re store lambs and replacement ewes/tups.
