I have three Nigerian does who have never had the covexin vaccination or any CDT vaccination before. The label directions are for sheep and say 5ml initially followed by a 2 ml booster. Is this correct? I was looking at some other goat sites and one of them recommend 4ml initially and then 2ml and another said 2ml initially followed in 2 weeks by another 2ml and then another 2ml in 2 weeks followed by 2ml in 6 months. Does anyone have any experience with this? Should I just follow the sheep directions? Thanks!
