Influence of Dietary Sodium Selenite on Tissue Selenium Levels of Growing Pigs
Effekten av natriumselenitt i fôret på selennivåene i organer hos gris.
Acta Veterinaria Scandinavica volume 23, pages 361–367 (1982)
Abstract
Twenty Norwegian Landrace pigs were divided into 5 groups and fed a basal diet consisting of a mixture of dried skim milk and whey powder together with ground barley. The diet was supplemented with 0, 0.2, 0.8, 1.2 and 2.2 μg selenium as sodium selenite and was fed for 12 weeks. The muscle selenium level was increased by a factor of about 4 and the liver selenium by a factor of about 12 when the dietary selenium supplement was increased from zero to 2.2 μg/g. There was a significant linear correlation between dietary selenium and selenium concentrations in tissues. Possible benefit for humans consuming meat from animals having received the selenium doses used in this experiment are discussed.

Sammendrag
Tyve griser med en gjennomsnittsvekt på 21 kg ble delt i 5 grupper og fôret med et grunnfor bestående av en blanding av skummet t0rrmelk og mysepulver blandet med byggrøpp. Fôret ble tilsatt hen-holdsvis 0, 0.2, 0.8, 1.2 og 2.2 μg Se/g som natriumselenitt og det ble fôret i 12 uker. Gjennomsnittsvekten ved slakting var 95 kg. Selen-nivået i muskulaturen økte med en faktor på omtrent fire og selen-nivået i lever med en faktor på omtrent tolv når selentilskuddet i fôret økte fra nuil til 2.2 μg/g. Det ble funnet signifikante sammenhenger mellom mengden seien tillsatt i fôret og selennivåene i lever og muskel. Grisene i kontrollgruppen utviklet muskeldegenerasjon. Humant kon-sum av kjøtt fra griser som har fått de selendosene som er blitt benyt-tet i dette forsøket er diskutert.
