An Investigation Into The Effect Of Luye Functional Premixed Feed On Pig's Blood Biochemistry Index, Amino Acids, And Trace Elements In Its Liver And Kidney

Functional feed, also referred to as health feed, is a kind of special feed with certain specific functions such as raising immunity and improving animals' anti-stress. Similarly, Functional premixed feed is referred to as health premixed feed which is composed of trace elements such as Fe, Cu, Mn, Zn, I and Se, vitamins such as Va, Vd, Ve, Vbl and Vb2, amino acids, other specific functional constituents and carriers, with each mixed in certain proportion. Functional premixed feed has some special functions such as removing ammonia and odors and improving animals' anti-stress.This thesis investigated the effects of a new functional premixed feed, or alternatively referred to as a Luye functional premixed feed which can improve pork's flavor quality, on Sutai pigs' and Duroc pigs' blood biochemistry index, pork's amino acids, change of the contents of trace elements and the residues of harmful elements in the pigs' liver and kidney. The results show that this functional feed does not impose an obvious influence on the various biochemistry index of Sutai pigs' blood; when Sutai pigs and Duroc pigs are fed the same amount of daily feed, total content of amino acids of Duroc pigs is slightly higher, but the difference is not significant. In comparison with both the control group of Sutai pigs and Duroc pigs, total content of amino acids of Sutai pigs that are fed the Luye functional premixed feed significantly increased. The content of Cu and that of such harmful trace elements as As, Hg, Pb, Cr and Cd in livers and kidneys of the Sutai pigs of the experiment group meet the nation's food safety standard, while content of Zn in them is significantly higher than that of the control group; the pork is therefore safe to be consumed.
