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 2

Selenium, MDA, and thyroid status of cows without (non-RP) and with retained placenta (RP) 12 hours postpartum, independently of SS and TAc supplemental treatment. Parturition was induced using prostaglandin F_2𝛼.

RP status (number of animals)	Blood Se (ng/mL)	Blood GPx (µkat/L)	Plasma MDA (µM)	Plasma T3 (nM)	Plasma T4 (nM)
Non-RP (𝑛=19)	176±33	181±34	4.68±0.93	1.31±0.41	42±13
RP (𝑛=14)	138±40^∗	133±48^∗∗	5.32±0.80^∗∗	1.37±0.34	51±11^∗∗
