“…The ability to maintain homeothermia during cold stress by increased metabolic rate is shown to be poorly developed in newly hatched chicks of domestic fowl (Freeman, 1963) and Japanese quail (Spiers et al, 1974). In the present investigation the chick of willow grouse was observed to pant and shiver one day after hatching.…”

“…This increase might be due either to a progressive raising of the set-point temperature, or an improvement of the chicks' total thermoregulatory potential. Hence it seems to be a general phenomenon among homeotherms since a progressive raising of the deep body temperature with age also has been observed in pigeons, rabbits, chicks of domestic fowl (Ginglinger and Kayser, 1929;Randall, 1943) rats (Hill, 1947), dogs, rats, rabbits (Gelineo and Gelineo, 1952), humans (Babak, 1902;Briick, 1961), and Japanese quail hatchlings (Spiers et al, 1974). in the experimental box were similar to the average T c measured in 25 adults at about the same time of the day (Fig.…”

Clocal temperatures (Tcl) of outdoor living captive willow grouse chicks (Lagopus lagopus lagopus) were found to increase from 39.4 +/- 0.5 degrees C. the first day to 40.3 +/- 0.5 degrees C. the twelfth day after hatching. Average Tcl of adults was 40.7 +/- 0.3 degrees C. When left alone for 30 min. in a controlled test environment providing temperatures ranging from 21 degrees C. to 46 degrees C., the one day old chicks preferred significantly higher ambient temperatures than eight day old birds. Tcl was significantly lower in the chicks tested the day after hatching than in the older chicks. It is concluded that the chicks' thermoregulatory behavior is essential for maintaining homeothermia, and that the birds' thermoregulatory set-point is low the day after hatching and climbs to adult level during the first week.

“…At day 14 post hatch, the adult follicle cell height of the thyroid gland is reached in precocial birds. The period of increase in follicle cell height coincides with the period of major increase in cooling resistance of young quail (Spiers et al, 1974). Takahashi et al (2005) found no effect on rectal temperatures with intra-peritoneal injection of T 3 or T 4 (0, 250, 500 and 1000 µg/kg, 8 treatments) in 2-day-old chicks.…”

The emergence of thermoregulation in avian species is a complex matter in which neural as well as hormonal processes are involved. In a previous paper, the neural aspects of primary avian thermoregulation were discussed. In this paper the role of the hypothalamus-pituitary-thyroid axis (HPT-axis) and the hypothalamus-pituitaryadrenal axis (HPA-axis) in the ontogeny of avian thermoregulation is evaluated. The regulatory mechanisms and different important hormones of both axes, which have stimulatory or inhibitory effects, are discussed. Because the onset of functionality of the thermoregulatory system is of great interest, the ontogeny and functionality of the hormonal axes are clarified. There is a great difference between precocial and altricial birds in hormonal events as well as in neural processes which are involved in the emergence of thermoregulation. In precocial avian species the HPT-axis becomes functional during the mid-to late embryonic period while the same axis only becomes fully functional during the first week post-hatch in altricial avian species.As early as the sixties, the emergence of homeothermy in chickens was investigated. It was concluded that the thyroid gland plays an important role in the thermoregulatory mechanisms of newly hatched chicks. More recent studies however were not able to show any direct effect of the thyroid hormones on the thermoregulation of day-old chicks, although blocking the conversion of T4 to T3 caused a decrease in body temperature in young chicks. Thyrotropin releasing hormone (TRH) is known to act in thermoregulation in mammals and several authors have found an effect of TRH on the metabolism of young and older chicks. However, the exact mechanism still remains unclear.Because the HPT-and the HPA-axis show close relationships, the role of the HPAaxis in the ontogeny of thermoregulation is also taken into consideration in this review. In mammals as well as in birds, corticotropin releasing hormone (CRH) is involved in the primary thermoregulation.We conclude that the HPT-axis has an important role in the ontogeny of avian thermoregulation. The exact role of the HPA-axis remains largely unclear although at least CRH is definitely of some importance.

“…Thyroid function parallels the time course of developing thermoregulatory ability in Japanese quail (Spiers et at., 1974). T3 or T4 (300 /-Lgjkg) injected intraperitoneally was thermogenic in the neonate chicken (Freeman, 1970).…”
