Viruses were extremely âpopularâ in the â90s, which is when the term âAntivirusâ became common, but today viruses are the minority when it comes to malware. There are, however, a few at-large viruses currently evolving and spreading, these include âSalityâ and âVirutâ.
Thatâs especially true when it comes to the leg labeled health, and thatâs reason enough, Baker says, to consider vaccinating your calves at branding or turnout. Traditionally, the recommendation has been to wait until calves are at least four months old before administering any vaccines. That way, goes the conventional wisdom, thereâs a reduced chance that the antibodies in the colostrum will cancel the effects of the vaccine.
Calves at high risk of exposure should be vaccinated twice 4-6weeks apart before they are 6months old. They then require a 3rd booster injection at 6 months of age due to the possibility of maternal antibodies interfering with the initial 2 injections. Calves over 6months old need two vaccinations, 4-6weeks apart.
