In sheep production, obtaining twins is a key strategy to improve farm productivity. However, twin lambs are born lighter and smaller than singletons, which is associated with higher perinatal mortality, therefore the profitability of the productive system can be reduced. The intrauterine development of the offspring depends mainly on their genetic potential and the availability of nutrients and oxygen. The transfer of nutrients and gases between the maternal-fetal compartments responds to utero-placental blood flow and placental capacity (sufficiency), so that maternal undernourishment and placental insufficiency can adversely affect the development of the offspring by compromising the nutrient and/or oxygen influx. This study was conducted on 60 corriedale bred sheep, separated by pregnancy rank (singleton or twin bearing). The sheep in this study underwent two nutritional plans from day 30 until the end of gestation, one that covered ~70% and another ~ 100% of the energetic-protein requirements of the pregnant sheep. The weight and body condition score of the sheep were evaluated every 30 days. At 100 and 140 days of gestation, caesarean sections were performed. Blood samples were collected from the umbilical vein of each fetus to evaluate variables associated with fetal oxygenation (PO2, PCO2, hemoglobin saturation with oxygen, hematocrit and pH). Fetal morphometric parameters were also measured (crown-rump length, thoracic perimeter, arm and leg length). Additionally, at 140 days of gestation, an evaluation of placental weight and morphology was performed. The results were evaluated by analysis of variance (ANOVA), where the fixed factors were the number of fetuses in gestation (single or twins) and the nutritional level (~70 or ~100% of the requirements established by the NRC), followed by the post-hoc Duncan test. Significant differences were considered at p≤0.05. At 100 days of gestation, no differences were evident in any of the variables studied. At 140 days of gestation the weight of the ewes fed with the control diet (~100% NRC) was greater than that of the ewes fed with the restriction diet (~70% NRC). The ewes from the single gestation control group (SC) had the highest body condition score when compared with the other groups. Twin-bearing ewes had higher values of total placental weight per sheep and a greater number of placentomes per sheep than those of single-gestation ewes. The single-gestation ewes had higher values of total placental weight per fetus and more placentomes per fetus than twin-bearing ewes. The predominant type of placentome in all groups were A and B, with a lower proportion of C and D. Fetal oxygen concentrations were higher in the single gestation control group (SC) compared to the other experimental groups. In addition, there was a positive correlation (r = 0.459) and statistically significant (p = 0.013) between the PO2 obtained from the umbilical vein and fetal weight at 140 days of gestation. All singletons were heavier than the twins...
