Sums and ratios of carnitine and acylcarnitines (AC) concentrations in uterine luminal fluid from Control (Con) and Pregnant (Preg) cows.

Metabolite groups	Group		P valuea	Log2 Fold-changeb
	Con (n = 8)	Preg (n = 10)
Total recoverable amounts of AC	239.56 ± 37.22	221.77 ± 25.88	0.69	−0.10
Total short-chain AC	75.86 ± 9.22	74.46 ± 9.22	0.92	−0.03
Total medium-chain AC	15.07 ± 1.23	13.43 ± 0.63	0.23	−0.17
Total long-chain AC	5.44 ± 0.52	4.80 ± 0.43	0.35	−0.18
Acylcarnitine/Free carnitine	0.68 ± 0.07	0.57 ± 0.04	0.22	−0.25
Total short-chain AC/Free carnitine	0.70 ± 0.07	0.64 ± 0.06	0.55	−0.14
CPT-I([C16 + C18]/C0)	0.046 ± 0.004	0.040 ± 0.004	0.32	−0.22
Total esters derived from DC/Total AC	0.032 ± 0.003	0.031 ± 0.003	0.84	−0.04
Esters derived from HO	4.69 ± 0.33	4.25 ± 0.29	0.33	−0.14
Esters derived from DC	6.98 ± 0.43	6.37 ± 0.32	0.25	−0.14

Acylcarnitines were categorized in esters derived from dicarboxylic acids (DC), esters derived from hydroxylated acids (OH), total short-chain acylcarnitines, total medium-chain acylcarnitines and total long-chain acylcarnitines. Values are expressed as nmol/cm² of endometrial area; mean ± SEM. Metabolite groups definitions are in Supplemental Table S2.

^aStatistical analyses were carried out by one-way ANOVA.

^bData are represented as fold-change of the metabolite concentration between Preg and Con groups.
