Q

If adult cattle have masses around their jaw/mandible area, what is an important observation you must make in order to make a diagnosis?

A

you need to determine if the mass is originating from the area between the 2 mandibles or the jaw bone itself.
If from the jaw, its lumpy jaw = actinomyces bovis
if between the 2 mandibles, its wooden tongue = actinomyces lignieresii

Q

what is the diagnostic approach / treatment for a bull with multiple cauliflower-like warts along his shoulder area?

A

these are most likely papillomas and can be plucked off if the base is small enough.
These warts are not harmful, but these animals cannot go to shows because this is contagious.

Q

How can you differentiate between waterbelly and acorn toxicosis?

A

acorn toxicosis leads to renal tubular necrosis and ventral edema which can appear very similar to waterbelly where urine is leaking out.
You should take an FNA of the area and place fluid on Azostick. If the BUN is high, it is waterbelly.
You should also check a blood sample to determine if the BUN is high. If the Blood BUN is normal, then the diagnosis is waterbelly. if the Blood BUN is low, then acorn toxicosis.
