Growth performance and oxidative status in piglets supplemented with verbascoside and teupolioside

Abstract

Two hundred forty piglets, half female and half barrows, 8.1 ± 1.40 kg LW, were divided into 6 experimental groups and fed ad libitum with a diet supplemented with the following levels of antioxidants: 0 (CON + = positive control added with 100 mg lincomicine/kg), 5 (LT = low teupolioside or LV = low verbascoside), 10 (HT = high teupolioside; HV = high verbascoside; LT+LV) mg/kg of diet for 56 days. Body weight and feed intake were recorded on d0, 14 and 56 of the trial. Ten piglets from each group were selected and blood collected by anterior vena cava puncture at 0, 14 and 56 d for reactive oxygen metabolite (ROMs) determination. HV showed final weight higher than the other groups (P<0.05), and oxidative stability was improved by both integrations of verbascoside. These results support the view that Verbascoside influences the growth performances and oxidative status of piglets.
