Abstract
|
|
|
|
Landrace(L), Largewhite(Lw), Korean Native Pig(KNP) and commercial hybrid were experimented to determine holothane sensitivity, RYR gene mutation and quality profiles. In the results of halothane test, the incidence of halothane positive pigs was similar between L and Lw. But, the rate of dubious halothane positive type was higher in L than Lw. In hal-gene analysis, halothane-positive pigs(nn) were not found in any tested breed and heterotype(Nn) appeared only in one pigs of L. Of the breed effect on the quality profiles, there were no differences in ?_(1)(? at 1hr postslaughter), but ?u(? at 24hr postslaughter) was significantly higher in commercial hybrid and KNP than other breeds(p＜0.05). Color assessed by National Pork Producers Council(NPPC) and CIE L^(＊) was significantly paler in L breed than other breeds(p＜0.05). Significant differences were found in water holding capacity(WHC) and cooking loss in KNP(P＜0.05).
