Abstract
Objective
This study investigated the effects of the administration of ethanolic saffron petal extract (SPE) and vitamin E on growth performance, blood metabolites and antioxidant status in Baluchi lambs.
Methods
Thirty-two Baluchi male lambs (35.22±5.75 kg) were randomly divided into 4 groups. The 1st (control), 2nd (ISPE) and 3rd (Vit. E) groups were respectively injected subcutaneously with either physiological saline (5 ml), SPE (25 mg/kg BW) or DL-α-tocopheryl acetate (225 IU) once a week. An oral dose of SPE (500 mg/kg BW) was also administered to the 4th group (OSPE). Feed intake and body weight were measured for 42 days and blood samples were taken on days 1, 14, 28 and 42. The lambs were slaughtered and tissue samples were taken.
Results
Growth performance and many blood metabolites were not affected (p>0.05) by the treatments. Cholesterol of plasma in the ISPE and Vit. E groups was similar and less (p<0.01) than both the OSPE and control groups. Although there was no significant difference between the control and other groups for plasma triglyceride, the ISPE group showed lower (p<0.05) triglyceride than the OSPE and Vit. E groups. The highest (p<0.01) plasma glutathione peroxidase (GPx) was detected in the OSPE group, while the ISPE and Vit. E groups showed higher (p<0.01) superoxide dismutase (SOD) of plasma than the control. Malondialdehyde of plasma in the ISPE group was lower (p<0.05) than the OSPE. No differences (p>0.05) were observed among the groups for antioxidant status of both of the longissimus dorsi muscle and liver. However, the activity of GPx in the kidney and heart, as well as SOD activity in the kidney, were influenced (p≤0.01) by the treatments.
Conclusion
Adding ethanolic SPE improved antioxidant status and lowered lipids oxidation in lambs. The SPE and vitamin E demonstrated similar effects on antioxidant status in lambs.
