I too myself are thinking of going MV or starting to go MV next year
The plan is to buy in a load of ewes next year (40-50 ish) of the shedding variety plus a tup, then become a closed flock and go fully MV, only buying in tups when I need them
That would put me at 150 ewes next year
I thought that if you did MV across a larger number then the cost would be spread more thinly and cost less per sheep? as in the brochure I have, as soon as you are above a certain number, its not all the sheep that need testing, just a % of them
So by doing your commercial ewes aswel, then maybe your costs per sheep would be lower
I may be wrong
