JOURNAL OF ANIMAL SCIENCE AND BIOTECHNOLOGY. 9, BIOMED CENTRAL LTD, 19/03/2018.

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. eng http://creativecommons.org/licenses/by/4.0/ open access Attribution 4.0 International Maternal undernutrition and offspring sex determine birth-weight, postnatal development and meat characteristics in traditional swine breeds journal article
