Abstract
In this study we intend to present 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 and number of farrowings), 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 of 92%; the average index of use for reproduction is of 2.33; the average number of piglets farrowed alive is of 14.48; the number of piglets farrowed dead is of 1.5. 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.

Key words: sows, reproduction, fertility, prolificacy
