It did not do much for jake eitehr, but then with him it may have just been more supportive to prevent infection from the COPD. I am going to try the Auromycin this year on him. He would not eat the sulpha powder well, we had to mix it with Calf Manna.
I never had any trouble getting any of mine to eat the sulfa, but they always looked like they had been snorting a boat-load of coke when they got done. ;o)
