In growing lambs a high proportion of protein retained (0.2-0.3) may be stored in wool. Protein retention is known to be increased by treating sheep with B agonists and there are indications that the extra protein is stored mainly in the carcass (Williams, 1987; Fiems, 1987). Wool growth rate at any time is determined by the relative availability of nutrients to all body tissues and is affected by, for example, pregnancy. It is also dependent on the kinetics of all competing biochemical reactions, which are altered by hormones (Black and Reis, 1979).To investigate the partition of protein between wool and other body tissues, a nitrogen balance trial was carried out with lambs fed on a diet with or without the B agonist, Cimaterol (Boehringer Ingelheim, Ingelheim, West Germany).
