The meat quality and stability to damage during keeping, to a considerable extent
hang from his acidity, which define in size pH through 1-2 ch after slaughter. In our
study is noted only trend to reduction pH on 0.09-0.14 inresearchsample of meat that
possible to value as positive phenomena. In general, as it was judged under the
investigation factor, meat (the longest muscle of the back) and search, and checking
pig had a high food quality. In checking group factor pH was noticeably undermost in
comparison with research group.
The highest estimations on tastings has got meat an animal fourth group.
Thereby if intensity of the growing characterizes meat productivity with
standpoint amount, that intramuscularadipopexis characterizes it with quality
positions. Such association exists beside animal of the fourth group.
On factor slaughter animals of search groups prevail over checking that points to
positive action of the selenium of the different sources on shaping meat quality beside
pig.
Installed [5] made an attempt to explain the essence of organic and inorganic
forms of selenium with reference to more than 70 primary sources. The author notes,
however, that only recent studies on yeast strains have shown that selenium
metabolically replaces sulfur, thus including high concentrations of selenium in yeast
cells. As a result, the importance of organic selenium in animal feed has increased
lately. The addition of selenium to the organic structure of selenoproteins at present is
an additional indication that the role of organic selenium in some biological
mechanisms may be more effective than inorganic forms. However, despite the large
number of studies in which the effectiveness of different forms of selenium is studied,
the author notes that so far there is no complete understanding of the role of selenium
in the body of animals. In the same work, the author summarizes the results of
scientific research in recent years on the comparative characterization of the evaluation
of various forms of selenium, which indirectly affects the results of our studies, in
particular the balance of selenium.
Since organic selenium is a component of an organic mixture of amino acid
analogues (from 40 to 50% selenomethionine), and sodium selenite is a water-soluble
compound, its absorption and absorption mechanisms will be different in the body.
Thus, in studies on pigs [3,7], in this connection it has been demonstrated that the
excretion of selenium in urine is much higher when applied to an inorganic form of
selenium compared with organic. For example, when feeding pigs with sodium
selenite and selenium yeast in their urine 42 and 21% selenium were allocated from
consumed amount, in starch – 22 and 27%, and kept – by 36 and 52%. The total amount
of selenium excretion was 64 and 48%. That is, inorganic selenium was allocated 16%
more than organic.
