Effects of feeding medium-chain fatty acid on nutrient digestibility of the peak lactation cows.

Digestibility (%)	Treatment		SEM	P-value
	CON	MCFA
DM3	68.56	67.90	1.427	0.82
Protein	66.02	66.56	1.652	0.88
Fat	70.04	74.43	1.661	0.20
NDF3	27.74	29.09	3.403	0.87
ADF3	25.83	24.37	3.445	0.84

SEM, standard error of mean.

^a-bMeans within a row with unlike superscripts differ (P ≤ 0.05).

¹CON, control treatment, basic diet with no medium chain fatty acids, n = 9. MCFA = MCFA treatment, basic diet and medium chain fatty acids 20 g/d, n = 9.

²Peak lactation, from 29 d to 70 d after calving.

³ADF, acid detergent fiber, NDF, neutral detergent fiber, DM, dry matter.
