AIMS: to investigate effects of Selenium (Se) supply during late gestation on colostrum quality and passive transfer of immunity in neonatal lambs.
MATERIAL AND METHODS: 80 Vendéen ewes were allocated to 2 treatment regimens. The treated group received a mineral preparation containing inorganic Na-selenite and organic Se yeast during the last 5 weeks of gestation providing a daily selenium supply of 15 µg/kg BW. The control group was left with low daily Se allowances (0.7 µg/kg BW). After birth lambs were left to suckle their dam naturally. The butterfat (BT) and Immunoglobulin G1 (IgG1) concentration in colostrum was assessed at parturition. The plasma Se and IgG1 concentration was assessed in lambs 24 hours after birth, and their Se status evaluated further at 20 days of life.
RESULTS: at allocation the ewes Se plasma concentration was low (26.3 ± 5.4 µg/L) in both ewe groups. One week after parturition the Se plasma concentration and the glutathione peroxidise (GPx) activity in the treated group were higher than in the control group (p<10-4). Similarly the plasma Se concentration and GPx activity in lambs were higher (p<10-4) in the treated than in the control group at each evaluation point. No effect of Se supply could be evidenced for colostrum BT (p=0.94) and IgG1 concentrations (p=0.50) and for lamb serum IgG1 concentration at 24 hours of life (p=0.35).
CONCLUSION: This study did not show any effect of selenium supply during late gestation on colostrum quality and passive transfer of immunity in neonatal lamb. However the selenium supply during late gestation enabled to restore the selenium status of deficient ewes and to provide their lambs with a satisfactory selenium status at birth.
