Abstract

Selenium fed to open cycling ewes in the form of sodium selenate or Astragalus bisulcatus (a selenium
accumulator plant) at 24 or 29 ppm selenium, respectively, in alfalfa hay pellets did not alter the
estrous cycle length, estrus behavior, progesterone or estrogen profiles, pregnancy rate or outcome of parturition
(P>0.05). There was wool loss in some ewes fed seleniferous pellets and the mean whole blood selenium
levels were 0.45, 1.3 and 2.4 ppm, respectively, for control, A bisulcatus and sodium selenate; however,
ewe condition and appearance remained good. All lambs appeared normal and the number of lambs born and
the individual and total lamb weight averages were not significantly (P>0.05) different between treatment
groups and control group.
