How now ?
How is your girl now, still on the mend ?
I really hope that gangrene does not affect that quarter, it can be very distressing for both you and your girl. Apart from the smell of rotting flesh you have to be ultra careful about milking the other quarters and ensuring that the infection does not spread.
I'm just wondering how she came to be infected in the first place, this sort of ailment can be caused by flies or the environment so if you can find out how it happened it may well save any future outbreaks.
I wish you both the very best, please keep in touch and keep us appraised of any developments.
