Results from this study1

No result from this study comes from a test of the peptide.

Natural levels measured1

These results measure the body's own peptide. Nobody was given the peptide. They are not evidence about taking it. They are left out of key results, evidence counts and charts.

    In 5-day-old chicks, hypothalamic oxytocin mRNA was greater in the low body weight line than in the high body weight line.

    In plain wordsIn young chicks, the body's own oxytocin gene activity in the brain was higher in the low-weight line than in the high-weight line.

    Summary · context
    Whole hypothalamus was collected from 5 day-old chicks that had been fasted for 180 min or had free access to food.
