The way I count them the degrees of freedom from the different particle species are:

Scalar, spin-0 (Higgs boson): 1

Massless vector bosons (Photons, gluons): 2

Massive vector bosons (W+, W-, Z): 3

Leptons: 2 (spin up and down) x 2 (particle/antiparticle) = 4

Quarks: 2 (spin up and down) x 2 (particle/antiparticle) x 3 (colour) = 12

There are 8 gluon, 6 quark and 6 lepton species in the SM so I get:

Total degrees of freedom = 1 + 2 + ( 8 x 2) + ( 3 x 3) + ( 6 x 4 ) + (6 x 12) = 128

Is this right??
