The LPS, milk yield and milk composition in the dairy cows fed the low-concentrate (LC) and high-concentrate (HC) diets

Item	Treatment
	LC	HC	SEM 1	p-Value 2
Rumen LPS, EU/mL1 (×103)	47.17	79.04b	7.94	<0.01
Plasma LPS, EU/mL2	0.47	0.86ab	0.08	<0.001
Milk 3
Milk yield, kg	28.05	26.92b	0.30	<0.01
Fat, %	3.40	3.09b	0.03	<0.01
Fat yield, kg/d	0.95	0.84b	0.02	<0.01
Protein, %	3.04	3.16a	0.03	<0.05

¹SEM = Standard error of the mean between the two groups.

²The LPS data were compared using Student’s t-test. The milk samples were compared using a paired t-test.

³The milk samples were obtained from the 1^st week to the 18^th week.

^abindicates p < 0.001; ^aindicates p < 0.05; ^bindicates p < 0.01.
