Cattle on stalks

I sampled a field today where cows were grazing stalks.  In the top photo they are all walking toward me to see what I am doing.  The cow in the bottom picture was not moving because she found an ear of corn as was eating it.  The cows get food value from the stalks.  For the cows, the ear of corn is like if you found a fresh donut in a bag of stale bread.
