Analysis of sex share in litters from which reproduction breeding sows of PL breed originated and the connection of litter traits with reproduction performance of sows reared by them



Analysis of sex share in litters from which reproduction breeding sows of PL breed originated and the connection of litter traits with reproduction performance of sows reared by them



Annales Universitatis Mariae Curie Sklodowska Sectio EE Zootechnica 18: 61-68



An attempt to estimate the influence of sex ratio 21 days after farrowing in litters from which breeding sows originated on their further fattening, slaughter and reproductive performance was undertaken using data collected between 1993 and 1998. 275 Polish Landrace sows and 791 piglets from their litters were studied.
