I am looking for help on treating lambs that were purchased and have diarrhe. I posted on a different thread, somewhat random info, however two lambs that are brothers were purchased at an auction...apparently, were very sick before purchase, but looked great walking through the ring...clean, no runny poop on legs or tail area... Sadly, one of the two didn't make it. He purchased several lambs from an auction(unfortunately not the best source, for health and quality..). Before putting them in a new clean and never used grassy pen, with deluxe homemade accommodations, He treated each lamb with sheep drench based on their actual weights, as a precaution. Once he noticed the runny poop in the brothers, and less than perfect in a few of the others, began dosing with corrid for a 5 day treatment, which just completed today. (The day the brother died) After seeing them just a few hours ago see that some may still have runny poop. How long does this take to go away?
