letting the cows out

Every year in spring time, March/April, we let all our cows and bulls out, back to the pasturing fields. The cold weather during the winter necessitates keeping the cows indoor so that they keep in good health.
The letting out of the cows is a very picturesque sight for the eyes as the cows are overjoyed and beyond themselves when let out again in the fields. They childishly kick their legs up high in the air whilst roaming in the field adjacent to the barns. The joy comes partly because they wil again graze freely the juicy and fresh grass as well as because they are no longer confined in their winter shelter.
