Tryptophan's influence on feeding and body temperature in the fowl

The neurotransmitter, serotonin, has been implicated in both food intake and body temperature regulation. In this experiment, the effect of tryptophan, the amino acid precursor of serotonin, on food consumption and rectal temperature in the fowl was determined. Single Comb White Leghorn cockerels we...

Zusammenfassung:The neurotransmitter, serotonin, has been implicated in both food intake and body temperature regulation. In this experiment, the effect of tryptophan, the amino acid precursor of serotonin, on food consumption and rectal temperature in the fowl was determined. Single Comb White Leghorn cockerels were intubated with a tryptophan solution or distilled water. Tryptophan significantly (P less than or equal to .05) decreased both food intake and body temperature of the birds. These results suggest that tryptophan may inhibit food intake via peripheral rather than central mechanisms.
