THE EFFECT OF DIFFERENT SELENIUM SOURCES ON PRODUCTIVITY AND CARCASS QUALITY OF PIGS

Abstract

Purpose - to study the effect of feeding selenium inorganic and organic forms on productivity and quality of pigs. To achieve this goal, it was necessary to solve the following problem:to examine the effect of selenite, selenate and Sel-Plex diet on performance and quality indicators pork. Level of the selenium in ration before 0,3 mg/kg dry material to account of the selenite and selenate sodium, as well as sowed; sel-plex raises the daily average increases pig relatively with checking analogue on 6,9- 13,1%. the Advantage of the organic form of the selenium (sowed; sel-plex) on selenite and selenate sodium on daily average increase forms 6,2 and 8,3%. the Accompaniment inorganic (the selenite and selenate sodium) and organic (sowed; sel-plex) of the forms of the selenium in ration assists the improvement destructive and meat-greasy quality pig - an increase the destructive mass and destructive output, masses flourishes, increasing of the meat specific gravity in touch under simultaneous reduction of the contents of the fat in touch. Herewith the best accumulation in meat specified element is noted beside animal with organic form of the selenium in ration - sowed;sel-plex.
