In this study, adult ewes received restricted (Restrict., 60% of NRC requirements) or maintenance (Maint.) diets from day 50 until day 90 (D 90) or day 130 (D 130) of pregnancy (length of gestation approximately 145 days). mRNA expression was quantified by ribonuclease protection assay. †Day effect (P < 0.01) for VEGF, VEGFR-1, and VEGFR-2. ‡Diet effect (P < 0.01) for VEGFR-1 and VEGFR-2. n = 5 ewes per group; s.e.m.= 193.7 for VEGF, 312.0 for VEGFR-1, and 203.1 for VEGFR-2.
