We've raised sheep for many years but have never had a year like this. We're losing a lamb a day to coccidiosis. We had a fecal test done for the diagnosis. We are treating their drinking water with Corid, and gave a Corid drench too. We've separated the symptomatic lambs from the apparently healthy, and we just have one of the symptomatic lambs left alive. Is there anything left to do? Next year we will drench the ewes with Corid 30 days prior to lambing, as I've seen suggested, as well as treat their water 30 days prior to weaning. This has been a very sad and costly experience.
