We have a pregnant cow in her 8th month that all of a sudden developed a smell like infection. My first thought was that she had a dead calf inside her but after putting her into the chute the smell was coming from her mouth but she was pretty fussy so decided to wait a couple days when the vet was coming to have more help and have him have a look. Turned out she has a hole the size of a nickle way back in the roof of her mouth going into her sinus cavity and the hay/feed she eats gets lodged and creates the infection. He felt that antibotics would not help do to the fact that it would just be ongoing because of the food. I have put her on very soft grass hay and some corn and seperated her. She is very diarrheatic and loosing weight. Hoping to save her and the calf. Any suggestions?
