Not so sure I agree with this Dave, and I think you're contradicting

management, then
say that your low cell count was genetic.
My cows are an amalgamation from wherever I could find them. 35 cows =

than genetics.
Do genetics play a part? Certainly, but I would say that they play a
relatively small part compared to management.
