Abstract
   The aim of this study is to present the reproduction performance recorded at Landrace x Yorkshire cross bred sows exploited for bacon production in an elite unit in Denmark. We have investigated several reproductive parameters: fecundity (depending on season), index of using sows for reproduction, prolificacy, number of piglets farrowed dead and the survival percentage to weaning. The obtained results were: average fecundity is between 91.66 and 92.22%; the average index of use for reproduction is between 2.35 and 2.37; the average number of piglets farrowed alive is between 14.35 and 14.37. The results are a consequence of valuable genetic material, as well as of the technology applied in the unit. The results are situated within the data presented in the specialty literature for these parameters.
