I have a Charolais/ Black Angus cross that has a little scours going on. She had this problem about 2 months ago but it cleared up after I added hay and took away the protein tub. I moved her to a new pasture of weeds 2 weeks ago ago. The other cows don't seem to have this problem. Her stool is like soft ice cream texture. It is brown in color (normal). I just lost one cow to a birth problem and another to pneumonia so I Am xtra careful now. Any ideas? The guy I got her from says she has been wormed. I'm thinking it maybe diet related. What do you suspect?
