I have about 20-25 cows in our open field. I just noticed one of our cows having these symptoms; puss coming out of eyes, weight loss, not moving, it used to just stand but wont run off like they used too. she lays there now, and will not even get up. Its almost like she is developing a cramp in her whole body. She used to lay and move her neck with her head above the ground, but now she is just laying there. She is still breathing and licking water as I feed her. Does anyone know whats she may have? :|
