Effect of dietary zinc sources on the relative messenger RNA (mRNA) expression levels of intestinal development-related genes in weaned piglets. Control, basal diet. ZnSO4, basal diet +100mg/kg zinc sulphate. Gly-Zn, basal diet +100mg/kg glycine zinc. Zinc lactate, basal diet +100mg/kg zinc lactate. The relative mRNA expression levels of jejunal Bcl-2-associated X protein (Bax; A), B-cell lymphoma/leukaemia-2 (Bcl-2; B), epidermal growth factor (IGF-1; C), and insulin-like growth factor-1 (IGF-1; D) were determined by real-time quantitative PCR. a,b Within a row, means without a common superscript letter differ (p<0.05).
