Abstract

Effects of levels of Bomboo Vinegar Liquids(BVL) on growth performance, serum profile and meat quality in employing 90 pigs were investigated. Ninety pigs were allocated into 3 groups and fed by dietary levels of BVL 0(control), 2.0 and 4.0% were included in experimental diets of each of the groups. Concentrated diet was supplemented with 2.0 and 4.0% BVL. The results showed that the daily weight gains and the feed conversion increased significantly(p<0.05) in 2.0% BVL and the feed intake increased slightly. The glucose and the cholesterol contents at the serum decreased significantly(p<0.05) in 2.0 and 4.0% BVL. On the other hand the total protein concentration and the blood urea nitrogen(BUN) increased significantly(p<0.05) in 4.0% BVL. The carcass weight increased significantly(p<0.05) in 4.0% BVL, and back fat thickness had decreased significantly(p<0.05) in 2.0 and 4.0% BVL. The carcass grade tended to increase in 2.0 and 4.0% BVL. The total fat content of loin tended to increase in 2.0 and 4.0% BVL while the cholesterol content decreased significantly(p<0.05). The pH had lower slightly in 2.0 and 4.0% BVL, the lightness and the yellowness of the meat color had higher significantly(p<0.05) while the redness decreased. Shear force values had lower significantly(p<0.05) in 2.0 and 4.0% BVL. For the fatty acid composition, the saturated fatty acids decreased significantly(p<0.05) in 2.0 and 4.0% BVL while unsaturated fatty acids(oleic acid and linoleic acid) increased significantly(p<0.05). For the sensory evaluation, 2.0 and 4.0% BVL had a significant(p<0.05) effect of diminishing the odor and improving the appearance. The taste was also significantly(p<0.05) improved. In conclusion the 2.0% BVL had a positive effect on the feeding performance, the carcass grade and the meat quality characteristics therefore 2.0% BVL is the appropriate supplemental levels of BVL for finishing pigs.

본 시험은 돼지에 대한 죽초액의 급여수준을 구명하기 위하여 육성비육돈 돼지 90두를 대상으로 대조구와 죽초액 2% 및 4% 급여구의 3개 처리에 10두씩 3반복으로 배치하여 55일간 사양시험을 실시한 후 육생산성, 혈액성상, 도체성적 및 육질특성에 미치는 영향을 조사하였다. 일당증체량과 사료요구율은 죽초액 2% 급여구에서 유의적(p<0.05)으로 증가하였으며, 사료섭취량은 죽초액 급여구에서 약간 증가하는 경향이었다. 혈중글루코스 농도와 콜레스테롤 함량은 죽초액 2%와 4% 급여구에서 유의적(p< 0.05)으로 감소한 반면에 혈중요소태질소 함량은 죽초액 4% 급여구에서 유의적(p<0.05)으로 증가하였다. 도체중은 죽초액 4% 급여구에서 유의적(p<0.05)으로 증가하였으며, 등지방 두께는 죽초액 2%와 4% 급여구에서 감소하는 경향이었다. 도체등급은 죽초액 2%와 4% 급여구에서 향상되는 경향을 나타내었다. 죽초액 2%와 4% 급여구에서 지방 함량이 약간 증가한 반면에 콜레스테롤 함량은 유의적(p<0.05)으로 감소하였다. pH는 죽초액 2%와 4% 급여구에서 약간 감소하는 경향이었으며, 육색의 명도와 황색도는 죽초액 2%와 4% 급여구에서 유의적(p<0.05)으로 증가한 반면 적색도는 감소하였다. 전단력가는 죽초액 2%와 4% 급여구에서 유의적(p<0.05)으로 감소하였다. 지방산 조성은 죽초액 2%와 4% 급여구에서 포화지방산의 비율은 유의적(p<0.05)으로 감소한 반면에 불포화지방산(올레산과 리놀레산)의 비율은 유의적(p<0.05)으로 증가함을 나타내었다. 관능평가에서 죽초액 2%와 4% 급여구에서 이취제거 효과와 외관이 개선되는 효과가 유의적(p<0.05)으로 나타났으며, 맛에서도 유의적인(p<0.05) 증가를 나타내었다. 이상의 결과로 볼 때 비육돈에 있어 죽초액 2% 급여가 증체량의 증가와 도체등급 향상에 비교적 유리하게 나타났으며, 등심육중의 콜레스테롤 함량의 감소, 연도의 개선, 이취제거와 외관의 개선, 맛의 증가 등의 육질 개선효과에 적정 급여수준임을 알 수 있었다.
