A Cow and Calf Moose with Cysts or Fibromas Tumors

While processing our cow and calf this year, we encountered a cyst in the fat, mostly in the cow but also in her calf.


The cyst where Gray/Black in colour and the size of a golf ball; however not round like a ball more closely resembled a frayed egg.

The cow had several in the fat cap along her back also in the fat and connective tissue in the front shoulder.

The calf had the same cyst and same size in the front shoulders only.

The cow had hair loss in the front shoulder area also. not extensive.

I didn't take any photos of the cyst
Just wondering if you had any insight as to this?




John-Paul, from your description I am going to say the balls are a form of Fibromas. They will not harm the moose or the meat around them.

There is an article about Fibromas Tumors on the website.
