Corid and Albon have variable effects on EMac and are not as consistent as Ponazuril in successful treatment. EMac can cyst in the intestinal tract and cause chronic protein loss, weight loss and lethargy. Rarely is diarrhea seen as with the other coccidian. Because the effects of Ponazuril on the developing fetus is unknown, it is recommended that females be at least 90 days out on their pregnancies and then treat THE ENTIRE GROUP for 3 days with Ponazuril and retest in 2 weeks.
We have heard Baycox has great success as well. Dose rate is 20mg/Kg. ( .18 x body weight = cc) Two regimens, 10 days apart, oral. The kicker is that it is really expensive - about $650 for a 1000 ml bottle.
