This study was conducted to investigate the effect of probiotic from pine needle microbes on growth performance, blood characteristics, carcass traits and economy of pigs. One hundred eighty pigs (L×Y×D, average body weight=75 kg) were grouped and housed with 15 animals per pen for 3 replications per each treatment. The ingredients and pine needle microbes mixed and fermented on anaerobic condition for 10 days to make the fermented diet. The basal diet was substituted with 0 (CON), 3 (T1), 5 (T2) and 10% (T3) of fermented diet, the pigs were fed for 42 days and slaughtered at the end of the trial to measure the carcass traits. Crude protein concentration of fermented diet on 10 day was higher (p<0.05) than that of on 0 day, while crude fiber concentration and pH were lower (p<0.05). The supplementation of fermented diet did not affect on growth performance and feed intake. Hemoglobin concentration of whole blood in T3 was higher (p<0.05) than that of CON, and hematocrit concentrations in CON and T1 were higher (p<0.05) than that of T2 and T3. The concentration of platelet was higher (p<0.05) in T1 than in T2 and T3. The CON had higher (p<0.05) total cholesterol, LDL-cholesterol and triglycerides concentrations than the treatments, whereas lower (p<0.05) HDL-cholesterol concentration. Carcass weight and dressing in T1 and T3 were higher (p<0.05) than those of CON and T2. The backfat thickness was higher (p<0.05) in CON and T2 than in T3. The carcass grade and economy improved by supplementation of fermented diet compare to CON. In conclusion, the supplementation of fermented diet using probiotics from pine needle microbes could improve health and meat quality and reduce the feed cost of pigs.

본 연구는 솔잎 토착미생물을 이용하여 제조된 발효사료 급여가 돼지의 성장, 혈액성상, 도체형질 및 경제성에 미치는 영향을 규명하고자 실시하였다. 평균 체중 75kg인 3원교잡종 (Landrance× Yorkshire×Duroc) 180두를 공시하여 돈방 당 15두씩 시험구당 3반복으로 실시하였다. 발효사료는 원료 사료와 미생물을 혼합 후 혐기적 상태로 10일간 발효시켰으며, 양돈용 사료에 0 (대조구, CON), 3 (T1), 5 (T2) 및 10% (T3)로 대체하여, 42일간 급여 후 도축하였다. 발효사료의 조단백질 함량은 발효 후가 발 효 전보다 높았지만 (p<0.05), 조섬유 함량과 pH는 낮았다 (p<0.05). 돼지의 혈중 Hemoglobin 함량은 T3구가 대조구에 비해 높았고 (p<0.05), Hematocrit 함량은 대조구와 T1구가 T2구와 T3구에 비해 높았 고 (p<0.05), Platelet 함량은 T1구가 T2구와 T3구에 비해 높았다 (p<0.05). 대조구의 혈중 total cholesterol, LDL-cholesterol 및 Triglycerides 함량은 발효사료를 대체한 모든 시험구에 비해 높았으나 (p<0.05), HDL-cholesterol 함량은 적었다 (p<0.05). 지육중량과 지육율은 T1구와 T3구가 대조구와 T2 구에 비해 높았으며 (p<0.05), 등지방 두께는 T1구와 T2구가 T3구에서 비해 낮았다 (p<0.05). 육 등급은 발효사료를 대체한 모든 시험구가 대조구에 비해 개선되었으며 (p<0.05), kg 증체당 사료비는 발효사료 를 급여했을 때 약 2~6% 적었다. 따라서 솔잎 토착미생물을 이용하여 제조한 발효사료의 급여는 돼지의 건강과 육 등급 개선 및 사료비 절감에 도움이 될 것으로 사료된다.
