Silage quality: Earlier housing and a faster depletion of grass reserves is bringing silage quality into focus for many at an earlier stage of the winter. The focus for most sheep farmers with mid-season lambing flocks at this stage is ensuring ewes are fed a maintenance diet and don’t lose valuable body condition. A 70kg ewe in mid-pregnancy will require in the region of 0.8UFL (1kg of air dry barley is equivalent to 1UFL) to satisfy maintenance demand.

The table shows energy values in UFL per kg dry matter for silage and hay of varying dry matter digestibility (DMD). On many sheep farms, silage quality is in the region of 65 DMD to 72 DMD, which is sufficient to meet maintenance requirements.
