  • Title: Ontogeny of brain temperature regulation in chicks (Gallus gallus domesticus).
    Author: Arad Z.
    Journal: Br Poult Sci; 1991 Mar; 32(1):203-10. PubMed ID: 2049624.
    Abstract:
    1. Development of brain temperature regulation was studied in the domestic fowl (Gallus gallus domesticus) from hatching to 21 d of age. 2. Body and brain temperature at hatching were relatively low compared with adult levels. However, both were effectively regulated at ambient temperatures of 30 and 35 degrees C, with only a minor difference between the 2 temperatures. 3. Body and brain temperature increased as a power function of age at significantly different rates, approaching adult levels at around 10 d of age and resulting in a linear increase in body-to-brain temperature difference with age. 4. The results indicated the existence of different patterns of post-hatching development of brain temperature regulation in relation to the degree of precocity of a species.
