Always heard that there are three milch breeds; Holstein, Guernsey, & Jersey and that Jersey milk is richest.
Didn’t know Angus are polled; this one didn’t need horns to pull off that rampage. Eat of the steaks carved from it and inherit its fighting spirit.
My dad worked for the president of the American Jersery Assn. back in the late forties and for an angus breeder afterwards.
You are right about the Jersey cow, It has a higher butterfat content than the other breeds.
And if memory serves, the Angus comes in black and red. And each can be polled or horned. I seem to have a memory of him talking about the differences waaaaaay back when.
