I know I give the vaccine before breeding. This is for my yearling virgin doeling. Then do I wait 21 days and give the 2nd shot, then again vaccinate at 4 weeks before freshing, then a week before freshing? This is what I have read in Health and Wellness but this sounds like a lot of vaccinations for Lysigin. Also 1 shot for Pasteurella or repeat in 21 days. My doeling has had this vaccine before. Thanks, and I sure do miss Vicki, and her world of knowledge!
