  • Fasting has severe effects on thyroid metabolism in the chicken: plasma thyroxine (T4) concentrations increase, whereas 3',5,3-triiodothyronine (T3) concentrations decrease. In the present report we studied the effect of fasting at the level of: 1) the pituitary (plasma thyrotropin (TSH) concentrations; the sensitivity of thyrotrophs to corticotropin-releasing hormone (CRH) and TSH-releasing hormone (TRH)); and 2) the hypothalamus (TRH content). A regulatory role of corticosterone is discussed… CONTINUE READING
