Extract

Store lambs produced from hill ewes make a significant contribution to lamb meat production, particularly during the winter months. Studies of store stock marketing in Scotland reveal that hill store lambs are criticised frequently for unpredictable growth, poor conformation and low carcass and saleable meat yields (1,2). Trials using Scottish Blackface lambs of a single strain and source suggest that poor performance is a function of inappropriate feeding method and premature slaughter (3). This trial looks at strain ,feeding systems and strain:feed interaction as sources of variation in the growth performance and carcass characteristics of Scottish Blackface lambs.
