Effects of Different Amounts of Supplemental Selenium and Vitamin E on the Incidence of Retained Placenta, Selenium, Malondialdehyde, and Thyronines Status in Cows Treated with Prostaglandin F_2α for the Induction of Parturition

Table 1

The effects of three different SS and TAc supplemental treatments (mean ± SD) on the incidence of RP, Se, MDA, and thyroid status of cows 12 hours postpartum. Parturition was induced using prostaglandin F_2𝛼.
