This report was presented at the UK Organic Research 2002 Conference of the Colloquium of Organic Researchers (COR).Under EU organic livestock regulations introduced in 2000, new restrictions were placed on the use of bought-in feedstuffs in hill systems. These reduced the non-organic annual percentage previously allowed in LFAs from 20% to 10% of annual dry matter intake. A further stepping down of these allowances may be introduced ahead of a complete ban in 2005. Bought-in feed supplements must therefore, be used strategically and offer “best value for money” in terms of ewe performance and lamb growth. The economic cost of supplementing the diet of twin-rearing ewes post lambing with either an approved non-organic feed block + half ration of commercial concentrate mix (B+CCM) or full ration commercial concentrate mix (CCM) was investigated. Lambs reared by ewes receiving the B+CCM diet had a greater liveweight gain than those reared by ewes receiving the CCM diet per kg of ewe supplementary feed. The costs in terms of kg lamb liveweight were lower for the B+CCM ewes than the CCM ewes
