1. 1. Plasma GH was greater (P < 0.05) on day 12 in ad libitum-fed birds compared to restricted chicks. Conversely, maximum GH levels were found to occur in the nutrient restricted chicks during the period of accelerated growth (day 42). 2. 2. A significant decline in circulating insulin concentrations with advancing age was evident in both ad libitum-fed and restricted chicks. 3. 3. Feed restriction significantly suppressed circulating T3 in restricted chicks, with concentrations returning to control levels upon refeeding. 4. 4. A significant increase in T4 with advancing age was evident in both treatment groups, with T4 being significantly greater in controls compared to restricted chicks at 54 days of age. © 1988.
