Morphometrical and statistical findings of the tissue layer thickness in the abomasum 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	49 ± 4a	41 ± 3a	39 ± 4a	25 ± 3a
Lp + Sb	pbt	pbt	96 ± 5	86 ± 6b	89 ± 5b
Tm	195 ± 10*	204 ± 10*	77 ± 5	79 ± 2	71 ± 4cd
Serosa	56 ± 3	32 ± 6e	30 ± 5e	25 ± 4e	23 ± 6e
Wall	313 ± 16	285 ± 10f	244 ± 18f	229 ± 14f	208 ± 29f

Lp + Sb = lamina propria 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 due to the fact that one structure will give rise to several others.

^aP = 0.0002 vs. group I.

^bP = 0.01 vs. group III.

^cP = 0.02 vs. group III.

^dP = 0.03 vs. group III.

^eP = 0.0002 vs. group I.

^fP = 0.002 vs. group I.
