Evaluation of selenium status in pure bred duroc sows and their progeny.
OBJECTIVE
The aim of this trial was to determine selenium status in pure bred duroc sows and their progeny and to compare it to Czech Large White x Landrace breed.


METHODS
The pregnant duroc sows (n=12) and pregnant Czech Large White x Landrace sows (n=12) were fed identical diets supplemented with sodium selenite.


RESULTS
During lactation significantly higher serum Se concentrations (p<0.001) were found in duroc piglets. Also significantly higher serum GSH-Px activities (p<0.001) were found in duroc sows and piglets. No differences in concentrations of Se in colostrums and milk were found between the two breeds.


CONCLUSIONS
Our findings support the hypothesis that there may be breed differences in indices of selenium status in pigs.
