In the present study, we aimed to evaluate the effect of supplementation of mineral nano particles on expression genes associated with piglet growth. The Duroc-Landrace-Yorkshire piglets weaned at 25 days were used for this study. Piglets of the experimental group was fed with basal diets supplemented with 12.8 mg/kg nMn, 160 mg/kg nFe, 16 mg/kg nCu, 0.8 mg/kg Co, 0.8 mg/kg nSe, and 160 mg/kg nZn. The commercially normal minerals were used for the control group. The qRT-PCR showed that the nano mineral supplementation induced the increase of CTGF and GHR transcript expression, while reduced the FST transcript expression in piglets for 20 days of treatment. After 40 days of treatment, the piglets using nano minerals showed the higher transcript expression of CTGF and GHR. However, the transcript expression of FST was reduced in group with nano minerals treatment. The result indicated that the ratio of mineral nano supplement could induce the changes of gene expression in piglet adipose tissue.
