RESULTS AND DISCUSSION
The basal level of Se in muscles (Table 2, Figure 1)
is comparable with the results reported by Driskell et
al. (1997) using a fluorometric method and also with
Koutnik and Ingr (1998) using atomic absorption for
the determination of selenium content in pork. Tissue
Se concentrations increase when higher dietary Selevels are provided. As was shown (Koutnik and Ingr,
1998), the Se content in the muscles of pigs (Seghers)
was significantly higher when feed with an addition
of Chlorella vulgaris was provided. More than twice
higher Se concentrations in muscles (MLLT, MSM)
were received when additional organic Se was supplemented to diets for pigs (Table 2, Figure l). Our
findings are comparable with the results when Seenriched yeast was fed to finisher pigs (Mahan and
Parret, 1996). The results reported by Mahan and
Parret (1996) suggested that a higher retention of Se
occurred when the organic Se source was fed compared with sodium selenite. Our and other studies
deal with the concentrations of selenium in pig meat
which may contribute to the solution of a sufficient
supply of this element into the human organism. The
FDA (1992) indicated that the terms “high”, “rich in”,
or “major source of” should be used when a serving
of food (in the case of meats, 100 g) contains 20% or
more of the Reference Daily Intake (also referred to
as Daily Value). Supplementation with organic Se
source in a pig diet is one of the possibilities how
to solve problems of sufficient supply of Se in human nutrition.
