The identified functional KEGG pathway annotation of differential serum metabolites in sows during pregnancy and after farrowing in the control and NCG groups. (A) KEGG pathway annotation of serum metabolites in sows on D30 of pregnancy. (B) KEGG pathway annotation of serum metabolites on D70. (C) KEGG pathway annotation of serum metabolites on D110. (D) KEGG pathway annotation of serum metabolites after farrowing. D30: the 30th day of pregnancy; D70: the 70th day of pregnancy; D110: the 110th day of pregnancy; F: after farrowing; ***: the KEGG pathway was significantly changed in NCG group compared with control group (p < 0.001); **: p < 0.01; *: p < 0.05; n = 8.
