[QUOTE="wbvs58, post: 1472454, member: 16453"] No, I would prefer a live vaccine for BVD it is just that our authorities won't approve the registration of one here, just the same our killed vaccine seems to be doing a good job but also I have a closed herd and have very good biosecurity. We probably are using a BVD vaccine for a different situation to you Creek. I am using it to give my heifers and the cow herd protection from breeding loss with BVD whereas while you are protecting your heifers from breeding loss down the track I would think your primary use of BVD vaccine would be protection of your young cattle both introduced and homebred while in your feedlot at this time of year. While BVD will not make them noticeable sick it drastically lowers their immune system and makes them susceptible to BRD organisms such as Mannheimia haemolytica. Ken All we got to clear up now is the cow thing, if you read Jeanne's last post again it might help. [/QUOTE]
