[QUOTE="wbvs58, post: 1803742, member: 16453"] I really can't see the point of it. BVD can be controlled pretty easily and cheaply through other means such as vaccination and biosecurity. Traders would be most at risk but they have no control on how the cattle they buy in were produced. I guess gene editing means they will produce a line of cattle resistant to BVD. There are two areas where BVD affects cattle, the first in breeding animals especially in unvaccinated 1st calf heifers and naieve older cows where the sudden introduction of a PI can result in loss of pregnancies and ill thrifty calves. The 2nd in intensive feeding situations where a PI can pass on a transient infection to healthy cattle lowering their immunity for a while to respiratory diseases. Maybe feedlots could offer a premium on cattle from these gene edited lines. The problem getting people to comply with the existing control methods for BVD makes me sceptical that uptake of gene edited lines would be any better. If it is going to cost money then that is the first big hurdle. Ken [/QUOTE]
