[QUOTE="Harris2346, post: 1544969, member: 37952"] Thank you that helps me understand it better about the mlv vaccines and the killed vaccines, trying to understand what vaccines I need to give and when and why is like trying to learn a new language but slowly Iam understanding it. What I have figured out is that the reason that it is so crucial that the calf get enough colostrum within the first couple hours of being born is because the calf gains temporary immunities from disease when they ingest the colostrum. But after a few weeks or months this temporary protection fades off, and calves must build there own immunities. That’s why calves need to be vaccinated,from there you need to come up with a vaccination program that best fits your operation. And A few things that I need to keep in mind is vaccinating to soon may not stimulate immune response because the calf may still have maternal antibodies in its system and the vaccination may interfere with building its own immunities and the body sees no need to respond. I plan on weaning my calves at 2 months old so I want to get them eating calf starter as early as soon as possible so by the time I wean them they are eating 2 pounds of calf starter a day. So if Iam going to wean them at 2 months of age I can tell my vaccination program will be completely different then all of you that have commented because you all are raising beef cattle and wean at a lot older age. And my operation is completely different then yours, I figured when and what vaccinations you give to your calves were the same in any operation but know I can see it’s not. But I am starting to understand it and I appreciate everyone’s comments, they have been very helpful. And with what you said about the sex semen you are absolutely right about dairyman using it a lot and there are way more heifer calves being born then bull calves, and that’s something I didn’t think about that could hurt the market for dairy heifers, because there would not be a need and demand for heifers so the market will go down. I plan on using sex semen also when I AI my nurse cows. [/QUOTE]
