I am having a strange thing happening in my flock of about 30 ewes and hope the folks here may have some idea of what is going on. Every once in a while one of the ewes will come up lame in a front foot. No fever, no swelling, have trimmed the feet and I'm not finding any sign of foot rot, by that the hoof is dry and clean. The ewe continues to eat well and has no sign of diarhea or anything else that would indicate illness. I have given LA200 shots but it doesn't seem to make a big difference. I catch the ewe, put her in a small pen by herself and after a couple or three days the limping disappears. This has happened with three of the ewes in the flock primarily. Two of the ewes are six years old the other is about three years old. The lameness began with an older ewe two years ago, she was pregrant with triplets and I layed it to ketosis. After the lambs were born the lameness disappears and she went on to raise the lambs with no other assistance. This year same senerio and a second ewe developed a limp and then a couple weeks ago a third ewe. The third one has taken longer to recover and at one point would not put weight on the leg. Kind of reminds me of my arthrictic knee acting up now and then. Thanks in advance for any ideas?
