Maternal undernutrition and offspring sex determine birth-weight, postnatal development and meat characteristics in traditional swine breeds Vázquez Gómez, Marta García-Contreras, C. Torres-Rovira, L. Astiz, S. Óvilo, C. González-Bulnes, A. Isabel Redondo, Beatriz Isabel Redondo, Beatriz Carcass quality Fatty acids Feed restriction Growth Iberian pigs Low birth-weight Malnutrition Ciencias 24 Ciencias de la Vida The aim of this study was to determine how maternal undernutrition during pregnancy and offspring birth-weight can affect the postnatal development of offspring under farm conditions, which may lead to consequences in its meat and carcass quality. The current study involved a total of 80 litters from Iberian sows fed a diet fulfilling daily requirements (n = 47; control) or providing 70% daily requirements (n = 33; underfed) from d 38 to d 90 of gestation when fetal tissue development begins. After birth, piglets born live were classified as low birth-weight (LBW; < 1 kg) and normal birth-weight (NBW; ≥1 kg). During the growing phase, 240 control and 230 underfed pigs (50% males and females) distributed by BW category and sex were studied until the slaughter.
