Getting a 12month bolus but want to do it in a month so it covers the danger periods and they don't have lambs on them to wrestle through. Just doing Min Vit drench as the ground is short of Cobalt
Cobalt from a drench only lasts a few days, at most, despite what a few suppliers claim (without ever putting it in writing ).
For Cobalt deficiency you really need to be looking at a bolus (or an imported jab of Troy/Sureshot) IMO.
