Well I may have screwed up big time. Due to illness and other obligations dad and I were able to make it through calving season with out any losses except to a wild cat and a two week old calve that fell and landed upside down in a treelap and caught pnumonia. Anyway we were unable to get bulls banded as they were born so we waited until roundup about 2.5 weeks ago. We always use the little green cheerio but tried the tribander. We wormed and I gave the bulls a tetnaus shot as well as banding. Calves still look healthy except when the flies are around the little black bags while they are nursing. These were feburary and march calves under three hundred pounds. I get on here and read horror stories and I am now worrried. I won't be able to give second shot due to their location. What do I need to be looking out for? and did I screw up badly?
