The Objective comparative estimation meat-greasy quality can be an attitude of
the meat mass to destructive mass pig. The Specific meat gravity in flourish pig
experimental groups formed 51.75 -52.20 against 51.90% in checking.
For specific fatgravity, he was undermost from checking on 0,09% only in
flourish animals 3 experimental group. The Correlation between meat and fat was
favorable in flourish experimental and checking animal - 1:0.260-0.265.
Under investigation factors have not rendered the unambiguous influence on
contents in meat moisture and protein (Table 2).

However, it decreased the concentration oxyproline. In meat pig 1 experimental
group contents this amino acid, has formed 0.08%. In meat pig 2 and 3 experimental
groups contents oxyproline were else smaller, than in checking, - on 0.09 and 0.12%
accordingly. Unlike oxyproline, the introduction selenic preparation in ration pig
research groups conditioned though and not more observable, but unambiguous
increasing to concentrations in meat of the contents tryptophan, which was positively
reflected on quality of meat.
In meat pig 2, 3, 4 exploratory groups, with checking relatively, increased the
contents calcium on 0.03-0.05% and phosphorus – on 0.02-0.06%. Herewith more
whole calcium and phosphorus was kept in meat pig 3 experimental group with organic
form of the selenium in ration.
The contents’increase of the selenium in ration pig research groups before 0.3
mg/kg DM rendered the assistance to the best accumulation in meat honeys, zinc and
manganese. If checking sample of meat contained these microelementsaccordingly
