The study was performed by examining the effects of fermented liquid of Crataegi Fructus on the lipid profile improvement in rats fed high fat diets. Sprague-Dawley rats of weighting $180.0{\pm}30g$ were randomly divided into five groups : basal diet (Normal control group, NCG), only high fat diet (High fat control group, HFC), high fat diet and supplemented with 1.69 mg/100 g body weight, 3.38 mg/100 g body weight, 6.76 mg/100 g body weight by fermented liquid of Crataegi Fructus - HFL, HFM, HFH group). These experimental diets were fed for 6 weeks. The fermented liquid of Crataegi Fructus fed groups had more significantly decreased in the levels of serum total cholesterol, triglyceride, LDL-cholesterol and atherogenic index than the high fat control group, while the HDL-cholesterol was higher when compared to the normal control group. Total lipid, total cholesterol, triglyceride, LDL-cholesterol contents in liver were decreased in high fat experimental groups. But the degree of increment was reduced by administration of fermented liquid of Crataegi Fructus. while the fermented liquid of Crataegi Fructus fed group had ore significantly increased in the level of HDL-cholesterol than the high fat control group. The singularity of the unsaturated fatty acid contents attracted our attention. Especially, the polyunsaturated fatty acid compositions were 36.36%, 34.70%, 20.31%in serum, liver and fecal of fermented liquid of Crataegi Fructus fed groups, respectively. These results imply that the fermented liquid of Crataegi Fructus can be used as possible food resources and medicinal food materials.

Two experiments were conducted to evaluate the effects of diet complexity and fermented soy protein on growth performance and amino acid digestibility. In Exp. 1, a total of 120 crossbred weanling pigs ($5.68{\pm}0.80\;kg$ BW) were randomly allocated into 4 treatments. Each treatment had 6 replicate pens comprising 5 pigs in each replicate. Experimental diets consisted of simple (soybean meal as protein source) and complex (soybean meal, rice protein concentrate, potato protein concentrate and fish meal as protein sources) diets; each diet contained 0 or 5% fermented soy protein (FSP), respectively. Dietary treatments included: i) simple diet; ii) simple diet with 5% FSP; iii) complex diet; iv) complex diet with 5% FSP. Pigs were provided each experimental diet for 20 d (phase 1) and then fed the same common diet for 10 d (phase 2). During days 0-10, pigs fed FSP diets had greater ADG than those fed non-FSP diets (p<0.05). G/F in FSP treatments was significantly higher than that in non-FSP treatments (p<0.05) from days 0 to 10. Throughout the overall period, G/F was greater in FSP treatments compared with non-FSP treatments (p<0.05). On d 10, N digestibility was higher in pigs fed FSP diets than in those fed non-FSP diets (p<0.05). Diet complexity did not affect growth performance and nutrient digestibility (p>0.05) in this experiment. In Exp 2, 12 ileal-cannulated, weanling barrows were housed in individual metabolism crates and randomly assigned to 1 of 4 treatments (same as Exp. 1) by using a $4{\times}4$ Latin square design. Among the essential amino acids, apparent ileal digestibility (AID) of Met and Val were increased in pigs fed FSP diets compared with those fed non-FSP diets (p<0.05). AID of Met, Phe and total essential amino acids were higher in pigs fed complex diets than in those fed simple diets (p<0.05). Among the non-essential amino acids, AID of Ala in FSP treatments was greater than that in non-FSP treatments (p<0.05). In addition, Asp, Cys, Glu, Pro, Ser and total non-essential amino acid digestibilities in pigs fed complex diets were higher compared with those fed simple diets (p<0.05). Interaction was observed in AID of Met, Asp and Pro. In conclusion, these results indicated that feeding of 5% FSP to nursery pigs improved feed efficiency and AID of amino acids, and diet complexity did not maximize the growth performance of pigs in the subsequent phase.

The study was conducted to investigate the dietary supplementation of citrus by-product (CBP) and CBP fermented with Bacillus subtilis (BS) or B. pumilus (BP) on growth performance, feed utilization, innate immune responses and disease resistance of Korean rockfish Sebastes schlegelii. Triplicate groups of juvenile fish (initial weight of 22.9 g) were fed one of five experimental diets which were formulated to replace a synthetic vitamin C (L-ascorbyl-2-polyphosphate, LAPP) with CBP or fermented CBP. A basal diet without LAPP and CBP was used as the control diet (Con). At the end of the 13 weeks feeding trial, growth performance, feed utilization and survival of fish fed the Con were significantly lower than those of fish fed the LAPP, CBP and fermented CBP diets. Fish fed the Con were significantly lower in lysozyme activity than fish fed LAPP, CBP and fermented CBP diets. In a challenge test against Edwardsiella tarda, cumulative mortality of fish fed LAPP, CBP and fermented CBP diets was significantly lower (20-30%) than that of the Con (60%). The findings in this study indicate that the CBP and/or fermented CBP can be a promising vitamin C source for LAPP replacement in diet for Korean rockfish.

Objective: This study was investigated the effects of dietary supplementation of Antrodia cinnamomea fermented product on modulation of antioxidation, anti-inflammation, and lipid metabolism in broilers. Methods: Functional compounds and in vitro antioxidant capacity were detected in wheat bran (WB) solid-state fermented by Antrodia cinnamomea for 16 days (FAC). In animal experiment, 400 d-old broiler chickens were allotted into 5 groups fed control diet, and control diet replaced with 5% WB, 10% WB, 5% FAC, and 10% FAC respectively. Growth performance, intestinal microflora, serum antioxidant enzymes and fatty acid profiles in pectoral superficial muscle were measured. Results: Pretreatment with hot water extracted fermented product significantly reduced chicken peripheral blood mononuclear cells death induced by lipopolysaccharide and 2,2'-Azobis(2-amidinopropane) dihydrochloride. Birds received 5% and 10% FAC had higher weight gain than WB groups. Cecal coliform and lactic acid bacteria were diminished and increased respectively while diet replaced with FAC. For FAC supplemented groups, superoxide dismutase (SOD) activity increased at 35 days only, with catalase elevated at 21 and 35 day. Regarding serum lipid parameters, 10% FAC replacement significantly reduced triglyceride and low-density lipoprotein level in chickens. For fatty acid composition in pectoral superficial muscle of 35-d-old chickens, 5% and 10% FAC inclusion had birds with significantly lower saturated fatty acids as compared with 10% WB group. Birds on the 5% FAC diet had a higher degree of unsaturation, followed by 10% FAC, control, 5% WB, and 10% WB. Conclusion: In conclusion, desirable intestinal microflora in chickens obtaining FAC may be attributed to the functional metabolites detected in final fermented product. Moreover, antioxidant effects observed in FAC were plausibly exerted in terms of improved antioxidant enzymes activities, increased unsaturated degree of fatty acids in chicken muscle and better weight gain in FAC inclusion groups, indicating that FAC possesses promising favorable mechanisms worthy to be developed.

Objective: Wheat bran (WB) was co-fermented with Aspergillus oryzae and phytase (Phy) to determine whether co-fermentation improve WB phosphorus and fiber utilization in Isa-brown layers. Methods: A total of 112 Isa brown layer were randomly divided into 7 treatments with 8 replicates per a treatment and 2 hens per a replicate. The treatments included basal diet (control), basal diet supplemented with 250 unit/kg Phy (control+Phy), diet with 10% WB (10% WB), diet with 5% WB and 250 unit/kg Phy (5% WB+Phy) diet with 10% WB and 250 unit/kg Phy (10% WB+Phy), diet with 5% fermented WB supplemented with molasses and phy (PCFWH) and 125 unit/kg Phy (5% PCFWH), and diet with 10% PCFWH (10% PCFWH). The intestinal microbial population, intestinal morphology, serum antioxidant enzyme activities, and excreta phosphorus content were assessed. Results: In PCFWH, spore counts, protease activity, xylanase activity, and ferulic acid were 8.50 log/g dry matter (DM), 190 unit/g DM, 120 unit/g DM, and 127 ㎍/g, respectively. Xylobiose and xylotriose were released in PCFWH, while they were not detectable in WB. Antioxidant capacity was also enhanced in PCFWH compared to WB. The 10% WB+Phy and 10% PCFWH groups produced higher egg mass, but hens fed 5% WB+Phy had the lowest amount of feed intake. Eggs from 10% PCFWH had better eggshell weight, eggshell strength, and eggshell thickness. Birds fed with 10% PCFWH also had higher serum superoxide dismutase and catalase activities. Compare to control, 10% PCFWH significantly reduced excreta phosphorus content. Conclusion: Diet inclusion of 10% PCFWH improved egg quality, antioxidant status, and excreta phosphorus content of laying hens.

본 연구에서는 발효콩 유지가 비만 억제 및 예방, 3T3-L1 지방전구세포의 성장 및 분화 억제 효과를 관찰하기 위해 실험을 실시하였다. 3T3-L1 지방전구세포에 발효콩 유지를 처리하여 세포생존율을 측정한 결과, NF군 $100{\mu}g/mL$에서 3T3-L1 지방전구세포의 생존율을 유의적으로 감소시켜 세포독성이 나타났다. 분화를 유도한 다음 세포 내 triglyceride 함량을 측정한 결과, 비발효콩 유지(NF) 처리군보다 발효콩 유지처리군에서 triglyceride 함량 저해 효과가 높게 나타났으며, 특히 BS, LBA, BLO군 순으로 높게 나타났다. 또한, BS군, LBA군, BLO군 순으로 지방세포분화 관련 유전자인 $PPAR{\gamma}$의 mRNA 발현을 농도 의존적으로 감소시켰으며, $PPAR{\gamma}$ 유전자와 상관관계에 있는 $C/EBP{\alpha}$ 유전자도 농도 의존적으로 감소시켰다. 그리고 adiponectin 유전자의 발현은 농도 의존적으로 증가시켰다. 고지방식이로 비만을 유도한 C57BL/6J 생쥐를 이용하여 항비만 활성을 관찰한 결과, 총 체중증가량은 대조군에 비해 4주째에 감소하는 경향이 나타났다. 혈액 내 지질농도를 측정한 결과 중성지방, 총콜레스테롤, LDL-콜레스테롤 함량은 LBA, BLO군에서 유의적으로 낮게 나타났으며(P<0.05), HDL-콜레스테롤 함량은 대조군보다 증가하였으나 유의적인 차이는 나타나지 않았다. 동맥경화 지수인 AI(atherogenic index)는 대조군보다 감소시키는 경향을 보였다. 비만관련 호르몬인 adiponectin의 농도는 SO, BS, LBA, BLO군에서 유의적으로 증가하였고(P<0.05), insulin 농도는 유의적으로 감소하였다(P<0.05). Leptin은 대조군보다 감소하였으나 유의적인 차이는 나타나지 않았다. 따라서 이러한 결과를 종합하여 볼 때 발효콩 유지가 3T3-L1 지방전구세포의 mRNA 단계에서부터 지방분화를 억제하여 항비만 활성을 가지고 있는 것으로 추정되고, 고지방식이로 비만이 유도된 C57BL/6J 생쥐에서 총체중을 감소시키고, 혈액 내 지질농도인 triglyceride와 총콜레스테롤, LDL-콜레스테롤 및 HDL-콜레스테롤과 비만관련 호르몬인 adiponectin, insulin, leptin을 조절하여 항비만 활성을 가지고 있는 것으로 확인되었다. 이 결과로 발효콩 유지가 항비만 생리활성을 나타내는 새로운 식품 소재로서 이를 활용한 기능성 식품 개발의 가능성이 있다고 생각된다.

Natto is a Japanese traditional soybean product fermented by Bacillus natto. The effects of dried fermented soybean (natto) supplement on egg production and egg qualities of layer chickens was studied with regard to the effective use of various waste foods in Japan. Dried natto, prepared by heating at $60^{\circ}C$, was added to a basic diet at a level of up to 3%. Forty 166-wk-old layer chickens (Rhode Island Red) were randomly divided into 4 groups and five layer chickens were used in each group with two replicates. Layer chickens in group 1 were fed a basic diet as the control. The remaining 3 groups were fed the basic diet supplemented with dried natto at levels of 1, 2, and 3% (w/w), respectively. The result did not show improvements in egg production or feed conversion ratio of layer chickens even when 3% dried natto was added to the control diet. The egg qualities including egg weight, eggshell strength and thickness, yolk color, yolk weight, albumen height, and Haugh unit were also not improved. However, the feeding of dried natto changed the cholesterol content in the egg yolk. The supplementation of dried natto showed the tendency to decrease the yolk cholesterol after 12-wk of feeding compared to the control diet though it did not change plasma cholesterol levels in the blood. On the other hand, yolk cholesterol decreased significantly after 12-wk of feeding 3% dried natto (p<0.05).
