Hi Dick, I think Nuflor was a good product, but now its possible to find better antibiotics without the side effecty of nuflor and that last enven between 5 an 7 days. Some new antibiotics doesn't burn, are not oily and really fluid to inject and have a stronger and larger effect then the old generation one.
I'm just waiting some answer from the labs to know the dosis for koļ carp.
I'll post that in a future thread.
