one shot of 3-4ml of dectomax is all thats needed but yeah they need to be kept out of the "infected" land/shed for at leasy 17 days. The lice that cause scab cannot live for more than 17 days max without a host (sheep) so in theory there could be a small percentage of lice that can reinfect sheep on land/gates/bushes etc up to 17 days after sheep are taken away from that field
Are you sure 3-4 ml for hoggets?... I was barely given hoggets 1ml when I did them a few years back.
1 ml per 33kg it says on the leaflet to treat scab
I think it's 1ml per 50kg with ivomec classic
sorry yes its ewes i gave my ewes 3-4 ml there big 80-90 kg sheep
Just a reminder that dectomax is an im injection when given to sheep
I see on another forum a member was giving it sub.
If a flock is injected with Dectomax say last November and mix with other sheep with scab over the winter on commonage will the treated sheep be immune for a period ?
no dont mix them with untreated sheep. keep them away
You wouldnt be able to stop sheep on commonage from mixing..
