Results from this study2

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

Natural levels measured2

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.

  1. 01AnimalEndogenous levelAnimal study (in vivo)Mechanism

    In primiparous dairy cows, mean oxytocin concentrations after tactile stimulation of the teats did not differ between automatic and conventional milking.

    In plain wordsIn dairy cows, the body's own oxytocin level after teat stimulation was similar with automatic milking and conventional milking.

    Summary
    After tactile stimulation of the teats either by hand or by the cleaning brush, mean oxytocin concentrations did not differ.

    Summary · context
    A comparative study was performed to evaluate the differences in behavioral and physiological stress responses during milking between cows that were milked by an automated milking system (AM-cows) and cows that were milked in a conventional tandem parlor (TM-cows).
    Summary · context
    In a randomized design, 36 primiparous Holstein-Friesian dairy cows were observed and blood sampled (1-min intervals) individually during milking.

    This result measures the body's own Oxytocin. Nobody was given the peptide. It is not evidence about taking it.

  2. 02AnimalEndogenous levelAnimal study (in vivo)Mechanism

    In primiparous dairy cows, elevated oxytocin levels were prolonged at the end of milking in automatically milked cows compared with conventionally milked cows.

    In plain wordsIn dairy cows, the body's own oxytocin stayed high longer at the end of milking with the automatic system than with conventional milking.
