WITH feed currently representing around 40% of a typical flock’s annual variable costs and some 20% of total cash costs, most sheep breeding businesses could do to boost performance by improving the efficiency of ewe nutrition this season.
Analysis of the latest annual Business Pointers costings by EBLEX shows average lowland and Less Favoured Area breeding flocks could both add £2/ewe to their bottom lines by boosting their feed cost efficiency to the level achieved by top third performers without any increase in lamb output (Table). For many this could represent the difference between profit and loss at the net margin level.

EBLEX identifies a whole host of ways in which flocks can realise such feed cost efficiency gains from mid-pregnancy through to weaning in its new 20-page Sheep Better Returns Programme Manual on ewe nutrition. These primarily revolve around greater precision in feed analysis and supplementation aided by body conditioning scoring and pregnancy scanning.
Specific feed efficiency improvement opportunities identified include:
- Accurate analysis of key winter forages by a reputable laboratory to ensure the right supplements are provided at the right time for optimum performance;
- Strategic use of roots and forage brassicas to provide a high energy winter ewe diet requiring less supplementary concentrates;
- The best value ingredients in simple home-mixed concentrate rations formulated to avoid unnecessary as well as insufficient supplementation;
- Scanning and grouping all ewes by litter size as well as expected lambing date to ensure preferential supplementation of those bearing twins and triplets;
- Adequate trough space to allow each ewe in a group to receive her supplementary feed allowance, and ad-lib fresh water at all times;
- Body condition scoring throughout pregnancy so feeding can be fine-tuned to ensure all ewes lamb in the right body condition; and,
- Careful management of grazing with sufficient supplementation whenever the grass is less than 4cm high.
