Where ewes and lambs are retained indoors for a significant period of time, offering ewes concentrate supplementation will be vital in ensuring they reach their peak milk yield. Where ewes are supplemented indoors for a short period of time (a few days to a week), twin suckling ewes in good body condition will require 1kg to 1.2kg concentrate supplementation along with access to silage of 68 to 70DMD. Ewes in poor body condition will require 1.4kg to 1.5kg.
