JOURNAL OF ANIMAL SCIENCE AND BIOTECHNOLOGY. 9, BIOMED CENTRAL LTD, 19/03/2018. ISSN 2049-189110.1186/s40104-018-0240-6https://hdl.handle.net/20.500.14352/92647The 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.engAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/journal article2049-1891https://jasbsci.biomedcentral.com/articles/10.1186/s40104-018-0240-6open accessCarcass qualityFatty acidsFeed restrictionGrowthIberian pigsLow birth-weightMalnutritionCiencias24 Ciencias de la Vida
