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.
