Do the Nuclear Forces have analogs of the CMBR?

I'm guessing that like EM, at some point the universe was *just* cool enough that the strong and weak nuclear forces became distinct. At each of these points, wouldn't there have been a sudden burst of gluons and W/Z bosons throughout the universe which we should be able to detect? Or at least can we detect what they decayed into?

EDIT: Also might not something like this exist for gravity?

W/Z bosons are unstable, and gluons are subject to color confinement. Ever since a few milliseconds after the Big Bang, the universe has been below the temperature at which strongly-interacting particles become confined.

So there isn't a "cosmic gluon background" or "cosmic W/Z background" as there is for photons.
