Every year in the UK one hears stories about the RSPCA or police being called by a concerned member of the public because’there are cows standing in a muddy field with no grass’.
Of course cows can be, and are, put out into grassy fields in the winter. These are usually sown with a ryegrass ley and this download can tell you more about the management of this.
However, the alternative ‘fresh’ food is provided by brassica crops which are sown as part of the crop rotation. There are a variety of these, and you can learn more about them in this download. The ones currently being grown in the valley include forage rape, kale, and turnips. The cows eat the foliage and, in the case of turnips, the roots as well.
An electric fence is used to partition off strips in order to be able to periodically provide fresh strips of pasture. So if you see cows in a muddy field, look closely at what has been planted there. It may be that they are at the end of a day grazing kale.
Or it may be that they are grazing a root forage crop, have eaten the foliage, and are now down to the sweetest part of the plant – the root!
