Here's the deal. I raise several calves each year. Seems sometime in the past 6 months or less my supplier of jersey bull calves has picked up a fairly bad bug. Out of the last 7, I have lost 4, using the colostrums provided, within 2 weeks of birth. With the remaining having the same symptoms and getting worse. So I set down did a plan of attack and set about solving this. It has boiled down to; (all new arrivals) Colostrx - Gain a few days on the passing of bug from herd to calf. (first signs of symptoms 5 days out vs 1 or 2 on colostrums) Usual milk replacer mixed with 350 mg of Corid (for 5 days) Drop Corid back to a maintenance level of 175 mg after the 5 days. Treat with 90 mg Terramycin daily as needed for infections. The problem is the bug is very resistance to treatment. In 2 of the original 3 survivors the bloody stool, depression, lack of eating returned within 3 weeks and requires a re-treatment of 350 mg Corid. Followed by an additional antibiotic treatment. Once they get to solid food it seems to clear up (1 to go), but I am still watching. The supplier is quite interested in the results as well. Seems not only are the bull calves affected but his heifers as well. Now the part I don't get. I have been told another fellâa that gets calves from this guy is telling people he has no problems. If they scour he just feeds them a raw egg (shell and all) with the milk replacer and it clears right up. Claims he only lost 1 out of 10. Now it could be he is getting the pick of the litter and I get the sick ones (I doubt that the last 3 have come to me as they hit the ground, wet). Haven't talked to him personally, not sure he'd care to talk to me, being the competition and all. But given the suppliers problems with heifers and the painfully slow death (starvation) these guys were going thru, I doubt an egg is gonna fix them. Anyone hear of feeding a raw egg for scours, and/or as a Cocilidoses (sp) treatment?
