Abstract

This study was conducted to investigate the effects of dietary supplementation with condensed molasses soluble (CMS), which has economically benefitted as an alternative ingredient of molasses, on growth performance and meat quality in growing-finishing pigs. A total of 160 cross-bred growing pigs (LY×D) having body weight 27.3±1.78 kg, were allotted to 1 of the 4 treatment groups with 4 replications each, in a completely random block design. The experimental diet consisted of a basal diet (CON), with supplementation of molasses 3% (MOL 3.0), CMS 1.5% (CMS 1.5), and CMS 3% (CMS 3.0) to basal diet. Feed and water were provided ad libitum for 70 days. We observed higher feed intake in the MOL 1.5, CMS 1.5, and CMS 3.0 groups than CON group. The final body weight and weight gain were significantly improved in the CMS 3.0 group (p<0.05), as compared to CON group. Evaluation of the meat quality revealed no significant difference in water holding capacity, heating loss, and pH, among all experiment groups. This study indicates that feeding CMS results in improved growth performance in growing-finishing pigs without deterioration in meat quality, and has the potential to be used as an alternative ingredient of molasses in swine feed.

본 연구는 생산비 절감을 위하여 양돈사료 내 당밀 대체 Condensed molasses soluble (CMS)를 육성비육돈 사료 내에 첨가 급여하였을 때, 생산성 및 육질에 미치는 영향을 평가하기 위하여 수행하였다. 공시동물은 평균 체중 27.3±1.78 kg의 교잡종(LY×D) 육성돈 160두를 공시하여, 4개 처리구에 완전임의배치로 공시하였다. 시험사료는 시판 육성비육돈사료 급여구(무첨가구)와 시판사료에 각각 당밀 3 % 첨가구(MOL 3.0), CMS 1.5 % 첨가구(CMS 1.5), CMS 3 % 첨가구(CMS 3.0)로 설계하였다. 각 처리구별 시험사료와 물은 70일 동안 자유채식을 실시하였다. 생산성을 분석한 결과, 당밀과 CMS첨가구에서 대조구 대비 사료섭취량이 유의하게 높은 것이 관찰되었으며, CMS 3 % 첨가에 의해 대조구 대비 종료체중과 일당증체량이 유의하게 개선되는 효과를 확인하였다(p<0.05). 사료요구율은 당밀 및 CMS 첨가 그룹에서 대조구와의 통계적 유의한 차이는 관찰되지 않았다. 사양시험 종료 후 등심부위의 육질을 평가한 결과에서 보수력, 가열감량, pH 모두 처리구간에 유의적인 차이는 관찰되지 않았다. 본 연구의 결과는, 육성비육돈 사료 내 CMS 3%의 첨가급여는 육질의 저하 없이 생산성 개선 효과를 가지며, 양돈 사료 내 당밀 대체제로써 CMS의 활용 가능성을 시사한다.
