Partial correlation analysis between foaming performance and components of rumen fluid.

Items	Foaming performance of rumen fluid
	Foaming production (mL)	Foam persistence (min)
Protein (g/L)	0.49	0.75*
Total saccharide (g/L)	−0.69	−0.33
Ni (mg/Kg)	0.47	0.10
Na (mg/Kg)	−0.51	−0.45
K (mg/Kg)	0.43	−0.56
Ca (mg/Kg)	0.63	0.52
Mg (mg/Kg)	0.58	0.62
The sum of the cations (mg/Kg)	−0.55	0.50

¹Pearson correlation analysis was used for correlation analysis, *P<0.05, **P<0.01.
