What makes a good doe?

Clue No. 1: A good, tight udder with lots of milk.

I just had to share this photo I took over the weekend. It's such a simple photo yet says so much. 

To me, milk in the udder is like money in the bank. This doe is raising twins on pasture with no supplement. So far this spring she has needed no deworming and no medication. Neither have her kids. She's out there making money for me while I sit here and play on the computer. What more could a producer want out of a commercial meat doe?
