1Values are means ± pooled SEM, 𝑛=7. CC: all period fed lard diet; CT: post-weaning period fed fish oil diet; TC: lactation period fed fish oil diet; TT: all period fed fish oil diet.
2Effects of lactation (L) and the post-weaning (PW) or the interaction between lactation and the starter diet period (L × PW).
a,bMeans with different letters are significantly different (P < 0.05) among groups.
