Effects of two doses of verbascoside-based dietary supplement on performance, some blood parameters and plasma oxidative status in Lacaune suckling lambs were investigated. Twenty-four lambs were subdivided into three groups of eight animals each and fed per os dietary supplementation with a plant extract from Lippia citriodora containing phenylpropanoid glycoside verbascoside: the low verbascoside (LVB) group has received 2.5 mg/animal/day of natural extract and the high verbascoside (HVB) group has received 5.0 mg/animal/day and the control group (CON) has not received dietary supplementation. The experimental controls have regarded body weight, average daily gain, consumption and conversion index of milk and blood samples. The dietary supplementation with verbascoside in both the LVB and HVB groups resulted in an improvement in average daily gain (P<0.01), milk consumption (P<0.05), and serum lipid profile; the groups showed a decrease in triglycerides (P<0.05) and an increase in high density lipoprotein cholesterol levels (P<0.05). Plasma oxidative status in lambs supplemented with verbascoside showed an improvement in homoeostatic stability, that induced a significant decrease in reactive oxygen metabolites (P<0.01) and thiobarbituric acid-reactive substances (P<0.05) concentrations and a marked increase in serum concentrations of vitamin E (P<0.01) and vitamin A (P<0.05).
