To elucidate the efficacy of different soy protein sources on piglet's performance, a total of 280 weaned piglets ($Duroc{\times}Yorkshire{\times}Landrace$, $23{\pm}3$ d of age, $5.86{\pm}0.45$ kg initial BW) were allotted to 5 treatment diets comprising soybean meal (SBM), soy protein concentrate (SPC), Hamlet protein (HP300), fungal (Aspergillus oryzae) fermented soy protein (FSP-A), and fungal plus bacterial (A. oryzae+Bacillus subtilis) fermented soy protein (FSP-B), respectively. Experimental diets for feeding trial were formulated to contain each soy protein sources at 8% level to corn-whey powder basal diet. There were 14 pigs per pen and 4 pens per treatment. Experimental diets were fed from 0 to 14 d after weaning and then a common commercial diet was fed from 15 to 35 d. Also for ileal digestibility studies, 18 pigs were assigned to 6 dietary treatments as N-free, SBM, SPC, HP300, FSP-A and FSP-B with T-canulation at distal ileum for 6 days. At $14^{th}$ d of experimental feeding, the ADG was significantly higher (p<0.05) in SPC fed diet as compared with others. Similar trend was noticed during the 15-35 d and overall study (0-35 d). All the processed soy protein sources tested in this experiment improved (p<0.05) growth than SBM during overall study. The nutrient digestibility of GE, DM, CP and Ca showed lower (p<0.05) values in SBM and FSP-A fed groups than SPC and FSP-B treatments. The apparent ileal digestibility of TEAA, non-TEAA and TAA showed lower (p<0.05) in SBM treatments compared with other soy protein sources. The true ileal digestibility of TEAA, non-TEAA and TAA were lower (p<0.05) in SBM fed group than SPC and HP300 treatments, and lower than FSP treatments though they didn't achieve significant difference (p>0.05). Villous height and crypt depth was not affected by dietary treatments. In conclusion, the growth and digestibility of nutrients in weaned pigs fed SPC was superior to others. Also FSP-A and FSP-B showed improved performance than those fed SBM.

This study evaluated the effects of dietary inclusion of soybean (SM) and fermented soybean meal (FSM) on growth promotion in juvenile abalone Haliotis discus. Six hundred and thirty juvenile abalone were distributed into nine plastic containers. Three diets were prepared with 22% fish meal, 2% casein, and either 25% SM or FSM used as the protein sources in the experimental diets, and Undaria was used as a control diet to compare the effects of the experimental diets on the growth performance of abalone. The diets were assigned to three containers each and fed to the abalone once daily to satiation for 16 weeks. Weight gain and specific growth rate (SGR) were higher in abalone fed the SM diet than in those fed the FSM diet. Weight gain and SGR of abalone fed the SM and FSM diets were higher than those of abalone fed Undaria. The crude protein and lipid contents of the edible portions of abalone fed the SM and FSM diets were higher than those of abalone fed Undaria. SM was superior to FSM as a protein source in abalone feed. The SM and FSM diets facilitated greater growth than Undaria.

본 시험은 육계 사료 내 사과박 발효물, 계피 및 계피 첨가 사과박 발효물을 첨가 급여시에 육계 생산성, 혈액 성상 및 계육 내 지방산화도에 대해 미치는 영향을 조사하고자 실시하였다. 육계 Cobb 종 수컷 총 600수를 5처리 4반복 반복당 30수씩 공시하여 5주간 실험을 실시하였다. 실험 전 기간 동안 증체율 및 사료섭취량은 사과박 발효물을 급여한 처리구에서 다른 처리구에 비하여 최대 30g 이상의 유의적인 개선효과를 나타내었으며(p<0.05), 계피 및 계피 첨가 사과발효물 처리구에서는 무항생제와 비교하였을 때 유의적인 차이는 인정되지 않았다. 각 처리구간 혈액 생화학 및 혈구 분석에서는 전체 처리구 간 유의적인 차이는 없었지만 Glucose는 계피를 첨가한 처리구에서 감소효과가 나타났으며 향후 이에 대한 좀더 깊은 연구가 필요할 것으로 사료된다. 지방산화도는 각 처리구간 사이에 유의적인 차이가 나타나지 않았다. 결과적으로, 육계 사료 내 사과발효물의 첨가 급여는 육계에서 생산성을 개선시키는 효과가 있는 것으로 사료되며 현재까지 이에 대한 연구가 매우 부족하다는 것을 감안할 때 향후 이에 대한 좀더 깊은 연구가 필요할 것으로 사료된다.

Objectives : We investigated the effects of fermented soybean(FSOB) on body weight and examined whether hepatic lipid accumulation are inhibited by it in high fat diet-fed obese male mice. Methods : 8 weeks old, high fat diet-fed obese male mice were divided into 5 groups: C57BL/6N normal, control, FSOB(1), (2) and (3). After mice were treated with FSOB for 9 weeks, we measured body weight gain, food intake, feeding efficiency ratio, fat weight, plasma leptin and lipid levels. We also did histological analysis for liver and fat on the mice. Results : 1. Compared with controls, FSOB-treated mice had lower body weight gain and adipose tissue weight, the magnitudes of which were prominent in FSOB(3) and FSOB(1). 2. Compared with controls, FSOB-treated mice had lower feeding efficiency ratio and blood plasma leptin levels, the magnitude of which was prominent in FSOB(3). 3. Compared with controls, FSOB-treated mice had lower blood plasma total cholesterol and LDL-cholesterol levels. 4. Blood plasma AST and ALT concentrations were not changed by FSOB, indicating FSOB do not show any toxic effects. 5. Consistent with their effects on body weight gain, the size of adipocytes were significantly decreased by FSOB, whereas the adipocyte number per unit area was significantly increased, suggesting that FSOB decreased the number of large adipocytes. Hepatic lipid accumulation was decreased by FSOB. Conclusions : These results demonstrate that FSOB effectively reduces body weight gain, feeding efficiency ratio, blood plasma leptin level and improves hepatic lipid accumulation.

Poly-gamma-glutamic acid ($\gamma$-PGA) is a mucilaginous and biodegradable compound produced by Bacillus subtilis from fermented soybeans, and is found in the traditional Korean soy product, cheongkukjang. This study was carried out to evaluate the effects of $\gamma$-PGA from a food source on the concentration of the neurotransmitter GABA and its metabolic precursor glutamate in diet-induced obese rats. Eight-week old male Sprague-Dawley rats (n=60) were used. The rats were divided into two groups and obesity was induced by providing either a 10% control fat or 45% high fat diet for 5 weeks. The rats were then blocked into 6 groups and supplemented with a 0.1% $\gamma$-PGA diet for 4 weeks. After sacrifice, brain and serum GABA and glutamate concentrations were analyzed by high performance liquid chromatography with fluorometric detection. The rats fed the high fat diet had significantly increased body weights. $\gamma$-PGA supplementation significantly increased serum concentrations of glutamate and GABA in the control fat diet groups while this effect was not found in the high fat groups. In the brain, glutamate concentrations were significantly higher in the $\gamma$-PGA supplemented groups both in rats fed the normal and high fat diets than in the no $\gamma$-PGA controls. GABA concentrations showed the same tendency. The results indicated that $\gamma$-PGA intake increased GABA concentrations in the serum and brain. However, the effects were not shown in obese rats.

본 연구에서는 대두가공부산물의 하나인 비지(SCR: soybean crud residue)를 이용하여 만든 메주를 항비만 또는 혈중지질 개선용의 식 의약 소재로써의 직접적인 이용 가능성을 검토할 목적으로 우리나라의 전통메주 발효의 주요 미생물의 하나인 Aspergillus oryzae var effuses KACC 44990로 발효시킨 메주(ASCR)와 홍국 제조용으로 사용되는 미생물의 하나인 Monascus pilosus IFO 4480으로 발효시킨 메주(MSCR) 및 이들을 1:1(w/w)로 상호 혼합한 메주(AMSCR)를 제조하였으며 이들 메주를 각 2%씩 함유하는 고지방식이로 8주간 마우스를 사육하였을 때의 체중, 혈액 및 간 조직 지질의 함량 변동과 간 조직 ROS 생성계 및 소거계 효소의 활성을 측정하였다. SCR, ASCR, MSCR 및 AMSCR은 고지방식이 또는 비만으로 유도된 간, 심장, 신장, 고환의 비대 현상과 부고환 주변 지방의 함량을 감소시키는 효과가 있으며, 그 효과는 AMSCR>ASCR>MSCR>SCR 순으로 ASCR과 AMSCR에서 높았다. SCR, ASCR, MSCR 및 AMSCR은 고지방식이 또는 비만으로 유도된 혈청과 간조직의 중성지방과 총콜레스테롤 함량을 감소시키는 효과가 있으며, 혈청의 HDL 콜레스테롤 함량을 높이면서 LDL 콜레스테롤 함량을 낮추는 효과가 있다. 특히 ASCR은 중성지방의 함량을, 그리고 MSCR은 콜레스테롤의 함량을 각각 감소시키는 효과가 높으며, ASCR과 MSCR을 혼합한 AMSCR에서 종합적인 지질개선 효과가 높았다. SCR, ASCR, MSCR 및 AMSCR은 고지방식이 또는 비만상태에서 나타나는 간 손상을 예방하는 효과가 있으며 그 효과는 AMSCR>ASCR>MSCR>SCR 순으로 컸다. SCR, ASCR, MSCR 및 AMSCR은 고지방식이 또는 비만상태에서 나타나는 ROS 생성계 효소인 XO의 활성을 억제시킴과 동시에 ROS 소거계 효소인 SOD, GPX 및 GST의 활성을 높이는 효과가 있으며 그 효과는 AMSCR>ASCR>MSCR>SCR 순으로 컸다. 결론적으로 본 실험을 통하여 발효비지는 항비만 효과가 있을 뿐만 아니라 지질을 개선할 수 있음을 확인하였다.

This study was designed to determine total lipid and trans fatty acids(tFAs) content of 157 food items commonly consumed in the Korean diet and to prepare the database for the estimation of tFAs intake in Koreans. Total lipid and tFAs content was determined by Bligh and Dyer method and attenuated total reflection infrared spectroscopy, respectively. The content of tFAs in margarines ranged from 0.8% to 25.2%, depending on the manufacturers. In bakery products, cakes contained higher levels of tFAs(0.8~16.9%) than hamburgers(0.8~8.4%) and doughnuts(4.9~10%). The distribution of tFAs in crackers and cookies was wide(0.8~25%), whereas meat and fish products contained 0% to 8.9% of tFAs. Fried chickens had 0% to 14.6% of tFAs and French fries had 5.2% to 18.8% of tFAs. In noodles, nuts, chocolates and fermented fish sauces, tfAs were not detected.

This experiment was aimed at investigating the effects of dietary supplementation with fermented rice bran (FRB) or fermented broken rice (FBR) on egg-laying performance, egg quality, blood parameters, and cholesterol level in egg yolk of Hy-Line Brown egg-laying hens. Altogether, 144 Hy-Line Brown egg-laying hens (32-week-old) were randomly allocated to one of 4 dietary treatment groups, with 4 replicates per treatment. Of them, 3 treatments diets were prepared by supplementing the basal diet with 0.1% probiotics (PRO), 1% fermented rice bran (FRB), or 1% fermented broken rice (FBR) at the expense of corn. Hen-day egg production was higher (P<0.05) in PRO and FRB treatment groups than in the basal treatment groups. However, feed intake, egg weight, egg mass, and feed conversion ratio did not differ among the treatment groups. Additionally, supplementation with FRB or FBR did not affect eggshell strength, eggshell thickness, egg yolk color, and Haugh unit during the feeding trial. There was no significant difference in leukocyte count. Total cholesterol level was lower (P<0.05) in the FRB treatment group than in the basal treatment groups. Asparate aminotransferase, alanine transferase, glucose, and albumin levels were unaffected by dietary supplementation with FRB or FBR. Egg yolk cholesterol level was lower (P<0.05) in the FRB and FBR treatment groups than in the basal treatment groups. In conclusion, dietary supplementation with FRB or FBR improved egg-laying performance, and reduced the levels of total serum cholesterol and cholesterol in egg yolk of Hy-Line Brown egg-laying hens.
