These heifers are part of the 2016 milking string. they're out enjoying the grass and alfalfa on a cool fall day. Cool - but still warm enough that the grass is still growing.
To maintain the alfalfa, I don't cut it for 6 weeks before the first frost; that allows the plant to grow a little and store nutrients in its root so that it'll be ready to go next spring. In the meantime a little grazing doesn't hurt, and it saves the hay I put up for later in the winter and next spring.
