It was studied the influence of organic selenium, as a source of amino acids, micronutrients and vitamins, on the chemical, amino-acid and fatty acid composition of pectoral muscles in laying hens of Lohmann Brown breed. It is established that the use of organic selenium in the compound feed for laying hens does not significantly change the chemical composition of muscles, but leads to the accumulation of arachidonic, lauric, tridecanoic, myristic, palmitic fatty acids, reduces the fat and caloric content of meat. The indicators of the morphological composition of carcasses of laying hens are given, at the same time the effect of various doses of organic selenium on the organoleptic quality indicators of meat and broth is estimated. According to the complex evaluation of obtained results, it is established that the optimum dose of Sel-Plex for laying hens is 400 g per one ton of feed.
Sel-Plex is a selenium-containing preparation, which is obtained by using special strains of yeast grown on selenium-rich environments with a low sulfur content.
The aim of the research is to establish the influence of organic selenium on the quality of carcasses, including the amino acid and fatty acid composition of pectoral muscles.
When organizing the scientific and economic experiment on hens and carrying out a control slaughter we were guided by methodological guidelines of ARSRTIP (All-Russian Scientific Research and Technological Institute of Poultry).

To assess the effect of organic selenium on the chemical composition of pectoral muscles of hens, a control slaughter was carried out at the end of the scientific and economic experiment. In general, the study of fodder positively influenced the chemical composition of pectoral muscles.
The results obtained by us indicate an insignificant intergroup difference in the morphological composition of carcasses, however, it should be noted a probable (P<0.05) increase in the mass of edible parts in the carcasses of hens, which received rations with organic selenium.
There is evidence that the supply of protein and minerals affects the exchange of amino acids. Attention is drawn to the slight tendency to reduce the amount of essential amino acids in the muscles of all hens of experimental groups. Although the composition of fatty acid lipids in the pectoral muscles of experimental groups was not significantly different, but it was observed the probable decrease (P<0.05) of margaric acid, as well as the accumulation of arachidonic one, especially in the muscles of the hens of 4 experimental groups, which were given organic selenium.
When tasting pectoral muscles, the best indicators on appearance, aroma, taste, consistency and juiciness are recorded in the groups having been fed with organic selenium. The broth of all groups was highly appreciated by the tasters, but without any significant difference between the groups. Thus, there is no doubt that organic selenium actively influences the synthesis of unsaturated fatty acids in the pectoral muscles of laying hens of Lohmann Brown breed.
1. The use of organic selenium in the composition of mixed fodders for laying hens positively influenced the chemical composition of pectoral muscles, reduced the fat and caloric content.
2. As a result of the use of organic selenium the arachidonic, laurinic, myristic, margaric and palmithinic fatty acids accumulate in the pectoral muscles of laying hens. The unsaturation rate was higher in the hens receiving organic selenium in the amount of 400 g per one ton of feed.
