Seasonal changes in growth rate, feed intake, growth hormone, and thyroid hormones in young male reindeer ( Rangifer tarandus tarandus )
The levels of thyroxine (T 4 ), triiodothyronine (T 3 ), and growth hormone (GH) in blood serum from young male reindeer have been measured and compared with changes in body weight and feed intake during ad libitum and restricted feeding. All three hormones fluctuated during the year. T 3 changed in...
