  In gauge models with bigger number of Higgs particles their couplings to
fermions are more complicated then in the standard model (SM). The influence of
the Higgs bosons exchange on the neutrino production cross section in $e^-e^+$
collision ($e^-e^+ \rightarrow \nu N$) is investigated. The study has been done
in the framework of the left-right symmetric model with the rich Higgs sector
containing bidoublet and two triplets. The couplings of the Higgs particles
even to light leptons can be as large as the gauge bosons couplings. The total
effect of the Higgs bosons is small as a result of the big Higgs mass in the
propagators.
