Swiss Landrace pig

Boar of the Swiss Landrace breed (SUISAG)

Origin and development

The Swiss Landrace pig has been the subject of breeding programmes since the early 1900s. It derives from old native breeds and was significantly improved by breeds imported from various countries. The Swiss Landrace pig is bred as a dam line and is particularly suitable for the production of fertile and long-lived cross-bred sows.

Description

White pig with lop ears and an average of 16 teats.

Breeding objectives

Optimum litter size and minimal suckling losses. Small number of non productive sow days. Good lifetime performance with regular litters and low within-litter birthweight variation. Optimum weight gain with good feed conversion and medium-fleshed animals. Selection for E. coli F18 resistance.
