Plasma -tocopherol concentrations in control ewes
5–6 weeks prepartum (Table 3) were greater than the range
0.6–2.4 mg/L reported in pregnant control ewes in other
studies with E-vitamin supplementation (Capper et al.,
2005; Parraguez et al., 2011). When considered on a BW
basis, however, daily vitamin E intake (2.0 IU/kg BW) was
higher, as well, compared with 0.6–1.2 IU/kg BW in the
two mentioned studies. Also for the supplemented ewes,
plasma -tocopherol concentrations were higher, although
daily E-vitamin intakes were lower (6.5 IU/kg BW) than
reported for the two other studies (8.0–12.2 IU/kg BW).
