Effects of copper hydroxychloride on growth performance and abundance of genes involved in lipid metabolism of growing pigs

Supplementing Cu to diets fed to pigs at 100 to 250 mg/kg may reduce post-weaning scouring and also improve ADG and ADFI. Addition of Cu at 250 mg/kg in diets for pigs containing 5% animal fat improved growth performance, and it was speculated that this is due to the ability of Cu to improve animal fat utilization and enzymatic activity. Inclusion of 45 mg/kg of dietary Cu in diets for rabbits improved body mass gain by upregulating mRNA transcription of fatty acid transport protein, fatty acid binding protein, and carnitine palmitoyl transferase 1, indicating that dietary Cu may influence post-absorptive metabolism of lipids. However, the effect of supplementing dietary Cu on post-absorptive lipid metabolism in pigs remains inconclusive. Therefore, an experiment was conducted to test the hypothesis that addition of 150 mg/kg Cu from Cu hydroxychloride (IntelliBond CII; Micronutrients USA LLC; Indianapolis, IN) to a diet based on corn, soybean meal (SBM), and distillers dried grains with solubles (DDGS) improves growth performance of pigs, and that dietary Cu influences mRNA abundance of genes involved in post-absorptive metabolism of lipids in pigs.
