[Vitamin E serum levels in calves after various methods of administration].
We observed the levels of vitamin E in the blood serum of calves after peroral application of Combinal E (1 ml contains 20 mg of tocopherol acetate in water solution), after application through a fistula into the rennet stomach and after an intramuscular injection of Erevit (1 ml contains 300 mg of tocopherol acetate in vegetable oil). The fastest increase in the vitamin E level was recorded after the application of Combinal E directly into the rennet stomach. The application of Combinal E per os resulted in the same level of vitamin E in the ninth hour after application as in the third hour after application into the rennet stomach, the intramuscular injection of Erevit had a much lower effect on raising the vitamin E level in the blood serum of calves. It was confirmed that for a faster supplementing of vitamin E to the organism it is more suitable to give Combinal E perorally.
