¹LZM 150 = control diet + lysozyme 150 g/t, LZM 300 = control diet + lysozyme 300 g/t.

ALB = albumin, GLB = globulin, GPT = glutamate pyruvic transaminase, GOT = glutamate oxaloacetic transaminase, TP = total protein.

²Data are means of 8 sows.

³Data are means of 8 piglets from 8 sows.

^a,bWithin a row, means with different superscripts are different (P < 0.05).
