Winter feeding systems for autumn calving cows cannot manipulate body condition to the same extent in hill herds as in the lowlands. Maintaining the dry, pregnant hill cow economically in the grazing season means making use of rough grazings (SNRG) which will allow little body condition improvement. In effect, condition score needs to alter little throughout the year. Consequently, in the early part of the winter, at least, some concentrate supplementation is required for the moderate quality silage on offer from what are often limited supplies.
