The NA57 experiment at the CERN SPS has measured strange baryon and antibaryon production in Pb Pb collisions with 158 and 40 A GeV/ c beam momenta. Recent results on Λ, Ξ and Ω hyperon enhancements and from the transverse mass spectra analysis for the 158 A GeV/ c data sample are presented. The energy dependence of hyperon production at mid-rapidity is discussed.
