Results from this study3

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

Studies that did not test the peptide alone3

In this study, Oxytocin was a lab tool or a carrier, part of a mix, or the subject of a lab method. These results are not evidence about taking Oxytocin.

01AnimalNot a test of Oxytocin aloneAnimal study (in vivo)Other
In beef heifers given oxytocin, serum PGF2alpha metabolite tended to be greater with low than with normal luteal-phase progesterone (P = 0.09).
In plain wordsIn cattle, a uterine hormone marker after an oxytocin challenge tended to be higher when progesterone was low than when it was normal.

Summary
Serum concentrations of the PGF2alpha metabolite following oxytocin stimulation tended (P = 0.09) to be greater in heifers with low luteal-phase progesterone compared with heifers with normal luteal-phase progesterone.

Summary · context
Animals were individually fed a corn silage-based diet supplemented with fish meal (5% of DMI; n = 12) or corn gluten meal (6% of DMI; n = 13).
Summary · context
Oxytocin was administered i.v. (100 IU) to heifers on d 16 after estrus to stimulate uterine PGF2alpha synthesis.
In this study, Oxytocin was a lab tool or a carrier, part of a mix, or the subject of a lab method. This result is not evidence about taking Oxytocin.

In beef heifers with low luteal-phase progesterone, fish meal supplementation mitigated the PGF2alpha response to oxytocin (P < 0.05).
In plain wordsIn cattle with low progesterone, fish meal reduced the uterine hormone response to an oxytocin challenge.

Summary
Fish meal supplementation mitigated this response in heifers with low luteal-phase progesterone (P < 0.05), but had no effect on heifers with normal luteal-phase progesterone.

In beef heifers with normal luteal-phase progesterone, fish meal supplementation had no effect on the PGF2alpha response to oxytocin.
In plain wordsIn cattle with normal progesterone, fish meal did not change the uterine hormone response to an oxytocin challenge.
