abstract
Four groups (A,B,C,D) of nine, trained, male racing pigeons were starved for one day after two months of high energy ration intake and then subjected to a respiration chamber test. One week before, groups A and B were orally supplemented with 90 mg of L-carnitine daily, whereas C and D were given a placebo. A and C underwent flight simulation by electro-stimulation of the breast muscles. Flight simulation increased heat production, prevented a decrease in respiratory quotient due to feed deprivation, decreased T-4 plasma levels and increased weight loss. Feed deprivation caused lower plasma T-3 and T-4 levels. L-Carnitine decreased the rise in heat production during electro-stimulation but did not influence respiratory quotient, weight loss or thyroid hormones. L-Carnitine supplementation in pigeons improved efficiency of energy usage during heavy exercise, thus preventing energy losses due to anaerobic metabolism.
