산삼 부정근박 급여가 육성-비육돈의 생산성, 혈액성상 및 육질특성에 미치는 영향

Abstract

This study was conducted to evaluate the effects of dietary wild-ginseng adventitious root meal on growth performance, blood characteristics and meat quality characteristics in growing-finishing pigs. Ninety six pigs[(Landrace×Yorkshire)×Duroc] with average initial body weight of 68.29±0.31kg were used in 70d growth trial. Dietary treatments included 1) CON(Basal diet), 2) WGR1(Basal diet+0.5% wild- ginseng adventitious root meal), 3) WGR2(Basal diet+1.0% wild-ginseng adventitious root meal) and 4) WGR3(Basal diet+1.5% wild-ginseng adventitious root meal). The pigs were allotted into four dietary treatments with six replicate pens and four pigs per pen in a completely randomized design. For the whole period, final body weight and ADG were increased in CON treatment compared to WGR3 treatment(Linear effect, P=0.005). In blood characteristics, red blood cell(RBC) was significantly increased in CON and WGR2 treatments compared to WGR1 treatment (Quadratic effect, P=0.019). WGR2 treatment resulted in higher white blood cell(WBC) than CON and WGR1 treatments(Linear effect, P=0.041). WBC difference was significantly improved in WGR2 treatment compared to other treatments (Linear effect, P=0.042). Total protein was increased in WGR2 treatment compared to CON treatment (Quadratic effect, P=0.011). In cholesterol concentration of blood, total cholesterol, HDL-cholesterol, LDL-cholesterol and triglyceride were not significantly different among treatments. In meet quality, pH in WGR1 treatment was higher than WGR3 treatment(Quadratic effect=0.022). Water holding capacity(WHC) was significantly increased in WGR2 treatment compared to WGR3 treatment(Quadratic effect, P=0.050).
