Two types of feed that famers commonly feed their cattle in winter are hay or silage. On our farm we feed some of both. Hay is grass that was cut during the summer, dried and then baled into round or square bales. For the first time last year, we also fed our cows silage. Silage is the corn you see in the field chopped, leaves, corn, the whole darn plant, into small pieces. It is then packed into a pit of a bag where it "cures" so that during the colder weather it will be ready for the cattle. Silage can also be made made out of other times of crops.
The boy and a silage crew worked on putting up the silage for our cows this week. This is a neat YouTube video he made showing just a little bit of the process.
