We hypothesized that this phenomenon was induced by changes in the digestive function or in gastrointestinal hormone secretion at weaning. We therefore gave intravenous administrations of CCK-8 in order to establish whether or not it stimulated GH secretion. The administration in pre-weaned animals increased the GH level, but not ghrelin levels, which were significantly greater than in post-weaned animals. These results suggest that the regulation of somatotropic axis after feeding may be stimulated by peripherally secreted CCK. %A Kobayashi, Y. %A Onodera, M. %A Yoshida, M. %A Guilloteau, P. %A Katoh, K. %A Obara, Y. %P 421-424 %R 10.22358/jafs/73954/2004 %U https://doi.org/10.22358/jafs/73954/2004
