In my sheep herd (230 ewes with lambs there side) i have had a run of 70 lbs lambs develop scours. the lambs were the age that cocci was most likely the cause. after treating with Corid for five days the lambs looked better but a week later they were scouring again. I lost the first one i treated. then i had two more act the same way after treatment. maybe it isn't cocci so i treated with valbazen and scour halt. three days and they look dry and are looking filled out. I still am on guard but it is looking up. not sure if Cored is loosing its punch or do i have a worm i have not seen before. i should take a sample to the vet------in my spare time between 2 and 3 AM Thank goodness it is species specific. if it was in my goats i would have lost more than one.
