Tr. Batra et M. Hidiroglou, THE EFFECT OF SELENIUM SUPPLEMENTATION ON PLASMA SULFUR, MAGNESIUM AND SELENIUM PROFILES OF DAIRY-COWS, Canadian journal of animal science, 73(4), 1993, pp. 997-1000
Interaction of Se supplementation with sulphur and magnesium in blood
plasma were studied in dairy cows. Cows were divided into three groups
: (1) control, no treatment; (2) cows injected intramuscularly 21-10 d
prior to parturition with 45 mg Se and 2040 IU of vitamin E; (3) cows
intraruminally administered with two 30-g pellets containing 10% elem
ental Se 2 mo prior to expected calving. There were no significant eff
ects of Se supplementation on the plasma levels of sulphur and magnesi
um.
