Recent studes have indicated that there is a decrease in perinatal survival of apparently normal animals produced by somatic-cell nuclear transfer. Here we report that the cortisol and adrenocorticotrophic hormone (ACTH) profiles of cloned lambs in the first 4 weeks of life are significantly different to that of control lambs. The growth of cloned lambs however was not different to controls. These findings demonstrate that endocrine development may be altered in apparently “normal” clones.
