  The influence of the admixture of the $^{3}F_{2}$ state onto collective spin
oscillations and neutrino emission processes in the triplet superfluid neutron
liquid is studied in the BCS approximation. The eigen mode of spin oscillations
with $\omega\simeq\sqrt{58/35}\Delta$ is predicted to exist in the triplet
superfluid neutron condensate besides the already known mode
$\omega\simeq\Delta/\sqrt{5}$. Excitation of the high-frequency spin
oscillations in the condensate occurs through the tensor interactions between
quasiparticles.
  Neutrino energy losses through neutral weak currents are found to consist of
three separate contributions caused by a recombination of broken Cooper pairs
and by weak decays of the collective modes of spin oscillations. Neutrino
decays of the low-frequency spin waves can play an important role in the
cooling scenario of neutron stars. Weak decays of the high-frequency
oscillations that occur only if the tensor forces are taken into account in the
pairing interactions does not modify substantially the total energy losses.
Simple expressions are suggested for the total neutrino emissivity.
