I've been having problems this year, more than in past years, with haemonchus contortus, (the barber pole or wire worm), infestation with my ewes. I ran a fecal test yesterday. I got some fecal matter from the lambs and processed that seperate. I got some from several ewes and processed it. I also got some from my 9 month old St. Croix ewe lamb and processed it seperate. Of the three slides I had haemonchus contortus eggs showing up in both the lambs and the adult ewes but NONE in the St. Croix's slide. I thought that was very interesting since she runs on the same pastures as everyone else. She apparently is more resistant to that blood sucking parasite.
