Abstract

We investigated the effects of dietary supplements such as probiotics, illite, active carbon and hardwood vinegar on growth performance and meat quality characteristics in finishing pigs. One hundred fifty pigs ($Landrace{\times}Yorkshire{\times}Duroc$; $32.3{\pm}1.3 kg$ average initial body weight) were used for a 100 day experiment. Pigs were randomly placed into one of five experimented diet groups (control, 0.2% probiotics, 1.0% illite, 1.0% active carbon, and 1.0% hardwood vinegar) and were slaughtered at approximately 110 kg live weight. The addition of 1.0% active carbon and hardwood vinegar caused a decrease in free water while, WHC (water holding capacity) was higher compared with controls. Drip loss in hog flesh was decreased by feeding probiotics, illite, active carbon and hardwood vinegar. Cooking loss was decreased when hogs were fed hardwood vinegar. Lightness ($L^*$) and redness ($a^*$) were no difference between the all treatment groups, yellowness ($b^*$) was higher when feeding active carbon and hardwood vinegar by 1.0%. When hogs were fed hardwood vinegar, drip loss was decreased, and meat color was higher in sensory evaluation of fresh meat. In cooked hog meat, meat color and juiciness were higher in hogs fed hardwood vinegar. These results showed that supplementing hog diets with 1.0% hardwood vinegar may noticeably improve the meat quality of finishing hogs.

본 시험은 육성-비육돈에 대한 생균제, illite, 활성탄 및 목초액이 육질에 미치는 영향을 평가하기 위하여 생균제 0.2%와, illite, 활성탄 및 목초액을 각각 1.0%를 삼원교잡종($Landrace{\times}Yorkshire{\times}Duroc$, 평균체중 $32.3{\pm}1.3 kg$) 육성-비육돈에게 100일간 급여하여 전단가, 보수력, 육즙감량 및 가열감량, 육색, 신선육과 조리육의 관능평가 및 조직감을 분석하였다. 목초액과 활성탄을 각각 1.0% 급여할 경우 유리수분은 대조구에 비하여 낮았으나, 보수력은 높게 나타났다. 육즙감량은 생균제, illite, 활성탄 및 목초액을 급여함으로서 유의적으로 적었으며, 가열감량은 목초액을 1.0% 급여할 경우 적었다. 육색의 명도($L^*$)와 적색도($a^*$) 값은 모든 처리구에서 차이가 없었으나, 황색도($b^*$) 값은 활성탄과 목초액을 1.0%급여할 경우 높았다. 목초액을 1.0% 급여할 경우 신선육의 관능평가에서 육즙감량은 적었으며, 육색은 높았다. 또한 가열육의 경우에도 육색과 육즙 함량은 목초액을 1.0% 급여할 경우 높았다. 따라서, 육성-비육돈 사료에 목초액을 1.0% 첨가 급여할 경우 경쟁력 있는 브렌드 돈육의 생산이 가능하며, 농가소득 증대에 크게 기여할 것으로 기대된다.
