Serum concentrations of insulin, cortisol, insulin-like growth factor-1 (IGF-1), thyroxine (T4) and triiodothyronine (T3) were determined before and after feeding weaned piglets fed different diets in two experiments carried out in winter and summer. In experiment 1 the standard diet (CP - 20.2) was replaced with an isocaloric ration containing slightly less crude protein (17.5; diet 2). Diet 3 (CP - 19.6) was isonitrogenous with diet 1 but more concentrated. In experiment 2 the fishmeal supplement in the standard diet was replaced by yeast meal.
