My calves (500 and 400 lbs)developed Coccidia. We have been treating them with Corid Drench. I have found information that Coccidia come from fecal-contaminated ground. They are swallowed when a calf licks the dirt off its self. I want to know what I can put on the ground to kill any parasites in the piles of manure. I was thinking something like lime or bleach/water?
