Selenium status of feedstuffs and grazing ewes in Serbia
Status selena u hranivima za ovce na ispaši u Srbiji
Abstract
A total of 221 feedstuff samples (187 grain samples and 34 hay samples) were collected from 13 different locations on the territory of the Republic of Serbia. The results expressed as μg/kg have shown an average selenium content in grain samples of 34.3 ± 17.1 and 53.8 ± 18.7 in hay samples. However, a distinct difference was noted between samples collected from the locations north of the river Danube (52.8 ± 20.0 and 73.4 ± 21.3 for grain and hay samples, respectively) compared to the locations south of the Danube (23.3 ±15.4 and 41.7 ± 17.1 for grain and hay samples, respectively). GPx activity was measured in a total of 58 blood plasma samples collected from ewes grazing on 5 different locations. The average GPx activity was 157.4 ± 61.9 μkat/L and it followed a pattern similar to the distribution of Se in feedstuffs. GPx activity was higher in samples collected north of the Danube (212.8 ± 91.2 μkat/L), compared to ewes south of the Danube (66.9 ± 14.0 μkat/L). According to the obt...ained results and literature data Serbia can be described as a selenium deficient area, showing a marked deficiency on the locations south of the Danube.
Ispitano je ukupno 221 uzoraka biljnih hraniva (187 žitarica i 34 uzoraka sena) sakupljenih sa različitih lokacija na području 15 opština Republike Srbije. Rezultati izraženi u μg/kg pokazali su da je prosečan sadržaj selena 34.3 ± 17.1 μg/kg u uzorcima žitarica i 53.8 ± 18.7 μg/kg u uzorcima sena. Međutim, značajna razlika je uočena između uzoraka koji potiču sa područja severno (52.8 ± 20.0 i 73.4 ± 21.3 za uzorke žitarica i sena) u odnosu na uzorke sa južne strane toka Dunava (23.3 ±15.4 i 41.7 ± 17.1 za uzorke žitarica i sena). Aktivnost GPx je merena u ukupno 58 uzoraka krvne plazme ovaca koje su bile na ispaši na 5 različitih lokacija. Prosečna GPx aktivnost je iznosila 157.4 ± 61.9 μkat/L. Aktivnost GPx je pokazala distribuciju po lokalitetima slično kao i ispitivana biljna hraniva. Naime, aktivnost GPx je bila viša (212.8 ± 91.2 μkat/L) u uzorcima krvi ovaca na ispaši severno od Dunava u odnosu na ovce koje su bile na ispaši na južnim lokalitetima (66.9 ± 14.0 μkat/L). U skladu... sa postignutim rezultatima, kao i literaturnim podacima, Srbija može da se svrsta u seleno deficitarne regione, pri čemu lokaliteti južno od toka Dunava pokazuju više izražen deficit. .
