Together with good quality hay or silage, this will provide the ewe with all the essential protein, digestible energy and vitamins and minerals that she requires for healthy lambs. Ewes in poor condition should be fed Ewe Nuts or Sheep Mix, with the quantities gradually increased prior to tupping. As a guide, start with about 0.25kg per head per day, two weeks before tupping, and build up to about 0.5kg per day, tailing off again after tupping (this technique is known as flushing). In most cases ewes will need to be fed either Ewe Nuts or Sheep Mix from 6-8 weeks before lambing, and certainly in the 4 week period leading up to lambing. Introduce Ewe Nuts at a level of 0.25kg / head / day, and build up to a maximum of 1kg / head / day before lambing. Be careful not to overfeed young ewes or those lambing for the first time as this could produce lambing difficulties. Over fat ewes should be monitored and put on limited grazing. Fed at up to 0.5kg a day these can be used as a maintenance diet. After weaning, ewes should be kept on a low plain of nutrition with concentrates kept to a minimum or cut out completely, depending on availability of grass and condition of the ewe.
