  The inclusion of string fusion in Dual Parton Model results in the appearance
of diquark-antidiquark pairs in the sea with comparatively large Feynman-$x$.
Such antidiquarks can fragment into fast antibaryons, thus increasing several
times the corresponding yields in high energy $pp$ collisions for $x_F \sim 0.8
\div 0.9$. String fusion also results in an unusual dependence of inclusive
spectra on the multiplicity of secondaries. Some numerical estimations are
presented.
