I have read that if you choose to vaccinate you should not use medicated feed. I have found that non-medicated feed is not as readily available as the medicated type. How effective is the cocci vaccine?
I understand the vaccine is only effective against some of the strains of cocci. Amprolium is supposed to work on all of them, but some on here find themselves treating for cocci even using medicated feed.
I have commented on other cocci post. Cover the ground 2-3 times a year with hydrated lime and give Acidified Copper Sulfate every 2 months. Do this and you wont have a problem with cocci. ACS is a mineral. It is composed of citric acid, copper and sulfur.
