The aim of this work was to investigate the phenotypic expression and variability of lactation duration as well as phenotype correlations and regression of lactation duration with subsequent litter size and weaning to fertility estrus interval. The average lactation duration was 30.15+/-7.40 days, the most number liveborn and weaned piglets is after duration of lactation from 21 to 28 days. The most weaning to fertility estrus interval is after duration of lactation less from 21 days. A weakly low negative phenotypic correlation was expressed between the lactation duration and subsequent litter size and weaning to estrus interval.
