I'm sure most of you will recognise this old timer. 157 day meat withdrawal these days, presumably why it disappeared off the shelves in favour of marbocyl.
Long story short. Results back from a calf P.M. and lab culture revealed that the E. coli which killed it via navel ill is was resistant to 9/10 antibiotics tested. This being the one that can still challenge it.
I haven't got my eyes directly on the report yet, but fairly sure it is resistant to some ABs not used on this farm. And we're a closed herd.
