Abstract

This study was conducted to investigate the effects of bio-ion water on growth performance, blood characteristics and meat quality in pigs. Ninety nine crossbreed pigs $(Landrace{\times}Yorkshire{\times}Duroc)$ were randomly allotted to three treatments; CON (basal diet), T1 (basal diet with bio ion water from growing period), T2 (basal diet with bio ion water from finishing period). There were no significant differences in growth performance and carcass characteristics of pigs among treatments. The red blood cell and white blood cell were significantly higher (P<0.05) in diet added with bio ion water than the control. Proximate analysis (%), meat color, pH, drip loss (%), cooking loss (%) and shear force $(kg/cm^{2})$ were not significantly different (P>0.05) among treatments. The treatment 1 had lower saturated fatty acid (SFA) to unsaturated fatty acid ratio, but higher UFA concentration than those of control. The aroma of cooked meat in T1 was higher than other treatments. Thereby, overall acceptability sensory score of cooked meat in T1 tended to be higher than other treatments.

본 연구는 돼지의 육성기 또는 비육기에 Bio 이온수 급여에 따른 성장, 혈액분석 및 육질 특성 평가를 위하여 실시하였다. 시험구는 Bio 이온수 무 급여구 (대조구), 육성기 급여구 및 비육기 급여구로 3시험구를 두었으며, 각 시험구 당 33두의 3원교잡종 $(Landrace{\times}Yorkshire{\times}Duroc)$ 돼지를 배치하였으며, 총 99두를 이용하여 사양시험을 수행하였다. Bio 이온수 급여는 육성돈과 비육돈의 성장과 사료효율에 영향을 미치지 않았지만 (P>0.05), 비육기 급여구에서 일당증체량과 A등급 출현율이 높게 나타났다. 대조구에 비해 Bio 이온수를 급여한 처리구에서 혈액성상 분석 결과 적혈구와 백혈구의 수치가 증가하였다 (p<0.05). 일반성분, 육색, pH, 육즙감량, 가열감량 및 전단력에서 유의적인 차이는 나타나지 않았다. 지방산 분석 결과 육성기 급여구에서 포화지방산/불포화지방산 비율이 낮게 나타났고, 불포화지방산의 함량 비율이 가장 높게 나타났다. 또한 가열육 관능검사에서 향과 전체적인 기호도에서 높은 점수를 획득하였다.
