[QUOTE="Lucky_P, post: 1685244, member: 12607"] It's everywhere. If you've never had a case... your time is coming, eventually. Typically, we see it worst here (I live in the same county as Bigfoot) when it gets hot and dry, but heavy rains and temporary inundations may also increase exposure due to coating forages with silt/soil. I generally don't vaccinate until calves are 2 months old... before that, it's likely that colostral antibodies will interfere with response to bacterin. FYI, anything you're giving to cows hoping to pass antibodies along in colostrum needs to be given not less than 8 weeks or so prior to calving... maximum colostral antibodies are 'set' by 5 weeks pre-calving... anything given after that point won't be in the mix, for all intents & purposes.
