Body composition and blood parameters of newborn piglets from Alentejano and conventional (Large White × Landrace) genotype

This study aimed to compare the body composition and some blood parameters (glucose, albumin and insulin-like growth factor 1 (IGF-1) of newborn piglets farrowed by unselected Alentejano (AL) or conventional genotype (Large-White × Landrace (LL). Carcasses (12 of each genotype) and blood samples were obtained from a total of 34 litters (18 AL, 16 LL). Gestation length was 4d shorter in AL sows compared with LL sows. When adjusted for birth weight, carcasses of AL piglets showed higher percentages of dry matter (P
