[QUOTE="Bright Raven, post: 1494009, member: 27490"] Thank you, Dave. I will add a little on the recent findings regarding Modified Live Virus vaccines for IBR. A naive heifer is one never before exposed to the IBR virus. Upon first exposure of a naive heifer to the live IBR virus (through an MLV or the natural virus), the ovary is targeted, particularly, the corpus luteum. This can upset the estrus cycle. So it is important to give it 4 to 6 weeks prior to when you are going to turn the bull in or AI them. The publication says 6 weeks is preferable especially if you are breeding via AI. [/QUOTE]
