1Data are presented as relative fluorescence units as an indicator of transport abundance.

2Tissue, fetal membranes (FM), endometrium (ENDO), superficial glands (SG), deep glands (DG), and myometrium (MYO).

3Probability values for the effect of tissue, maternal nutrition, day of gestation, day × maternal nutrition, and day × tissue on the fluorescence of hexose and cationic amino acid transporter abundance.

4SLC2A1, facilitated diffusion glucose uniporter; SLC2A3, facilitated diffusion glucose transporter; SLC2A5, fructose transporter; SLC7A1, arginine, lysine, and ornithine transporter; and SLC7A2, arginine, lysine, and ornithine transporter.

5CON, Heifers fed a TMR that meets 100% of NRC requirements to gain 0.45 kg daily; RES, heifers restricted to 60% of CON diet.

6Mean fluorescence of maternal nutritional treatment groups across uterine tissue type.

7Average SEM for day × tissue interaction. Day 34 CON n = 6, day 34 RES n = 9, day 50 CON n = 7, day 50 RES n = 7.

8Average SEM for the day × maternal nutrition interaction.

9Mean fluorescence across maternal nutrition within tissue type.

a–cMeans within row without common superscript differ (P ≤ 0.05).

d,eMeans within column without common superscript differ (P ≤ 0.05).
