Morphometrical and statistical findings of the tissue layer thickness in the omasum of red deer during prenatal development (µm)
| Group I CRL (cm) (1.4–3.6) 30–60 days | Group II CRL (cm) (4.5–7.2) 67–90 days | Group III CRL (cm) (8–19) 97–135 days | Group IV CRL (cm) (21–33) 142–191 days | Group V CRL (cm) (36–40) 205–235 days | |

| Epithelium | 62 ± 5 | 119 ± 11a | 219 ± 18a | 390 ± 28a | 525 ± 30a |
| Lp + Sb | pbt 195 ± 10* | pbt 206 ± 13* | 99 ± 8b | 168 ± 14b | 164 ± 16b |

| Wall | 313 ± 16 | 364 ± 13a | 429 ± 30a | 744 ± 38a | 868 ± 29a |
Lp + Sb, lamina propia and submucosa; Tm, tunica muscularis; pbt, pluripotential blastemic tissue.
The pluripotential blastic tissue of Groups I and II, which will later give rise to the lamina propria and submucosa, were not statistically compared because one structure will give rise to a variety of others.
P < 0.05 vs. Group I.
P < 0.05 vs. Group III.
