Correlation coefficients between serum and colostrum immunoglobulin (IgA, IgG and IgM) content of sows ¹.

	Serum IgA	Serum IgM	Colostrum IgG	Colostrum IgA	Colostrum IgM
Serum IgG	0.006	0.082	0.571 ***	−0.063	0.438 **
Serum IgA		0.072	0.087	0.159	0.098
Serum IgM			0.007	−0.215	0.013
Colostrum IgG				0.115	0.995 ***
Colostrum IgA					0.184

¹ Colostrum Ig concentration averages at 0, 6 and 24 h; ** p < 0.01; *** p < 0.001.
