    Area of Science:

    • Comparative physiology
    • Neuroscience
    • Animal behavior

    Background:

    • Food intake regulation is a complex process studied for decades.
    • Most research has utilized rats, with fewer studies focusing on avian models.
    • Understanding avian feeding control is crucial for comparative physiology and animal science.

    Purpose of the Study:

    • To review current research on food intake control mechanisms in birds.
    • To compare avian feeding regulation with that of mammals.
    • To highlight the potential of birds as models for studying appetite control.

    Main Methods:

    • Literature review of studies on avian food intake.
    • Comparative analysis of avian and mammalian feeding mechanisms.
    • Discussion of neuroanatomical and physiological factors involved.

    Main Results:

    • Avian and mammalian food intake regulation share common control mechanisms.
    • Peripheral structures like the alimentary tract and liver play roles in avian feeding.
    • Specific brain regions (hypothalamus, striatum, olfactory bulbs) are implicated in avian appetite control.
    • Significant breed and line variations exist in how birds respond to feeding regulators.

    Conclusions:

    • Birds exhibit conserved food intake control mechanisms compared to mammals.
    • The avian model offers unique advantages for investigating the impact of growth selection on appetite regulation.
    • Further research is needed to fully elucidate the roles of peripheral organs in avian feeding behavior.
