Eh-jang (fermented aquatic products) of Asia can be classified 4 groups, those are Chot-kal (salted fish guts), Chot-kal Paste, Eh-ganjang (fish sauce) and Shic-hae (lactic acid fermented fish products). The native place of Eh-jang and rice culture is almost same and Eh-jang had been spread out all the area of Asia along with rice culture. Korea has variety of Chot-gal and consumes much Chot-gal that Korea is the culture area of both soybean sauce and Chot-gal. Eh-ganjang had been edible all area of Korea during Chosun Dynasty, but it remains only Southern part of Korea. Korean Chot-gal paste is produced as a form of Kon-chang-yi-chot. Korean Shic-hae had been edible all area of Korea during Chosun Dynasty, but remains at the east coast and some area of Hwang-hae Do and Kyung-sang-nam-do.

The present study was conducted with twenty-four Korean native (Hanwoo) steers to observe the effect of mixed oil and monensin supplementation and duration of feeding on c9,t11-CLA content in plasma and fat tissues. The steers were randomly assigned to three groups of eight animals each according to body weight. Hanwoo steers in the control group were fed the commercial concentrate for the late fattening stage. The other groups of steers were fed the same diet as control steers, but the concentrate was supplemented with high-$C_{18:2}$ oil mixture (soybean oil, sunflower oil, safflower oil) and fish oil at 6% level of concentrate (DM basis), and monensin (20 ppm). The second and third group of steers was fed the oil mixture supplemented diet with monensin for the last 10 weeks and 20 weeks, respectively, prior to being slaughtered. The oil mixture consisted of 45% soybean oil, 20% sunflower oil, 20% safflower oil and 15% fish oil. Average daily gain (p<0.049) and feed efficiency (p<0.018) of the steers fed the diet supplemented with oil mixture and monensin (OM-M) for 20 weeks were higher than those of the other groups of steers. Dressing percent, fat thickness and longissimus muscle area were not affected by the OM-M supplementation and duration of its feeding. The OM-M supplementation increased the content of total-cholesterol (p<0.0001-0.0007) and HDL-cholesterol (p<0.0001) in the plasma of steers compared to the control diet. The steers fed the OM-M diet had a higher proportion of c9,t11-CLA in plasma (p<0.048-0.044) than the control steers. Feeding the OM-M diet for 20 weeks increased the proportion of CLA in intramuscular (p<0.015), intermuscular (p<0.039) and subcutaneous (p<0.001) fat tissues compared with both steers fed the control diet and the OM-M diet for 10 weeks. Increased (p<0.007) proportion of total unsaturated fatty acids in steers fed the OM-M diet for 20 weeks compared to those in control steers was related to the increased (p<0.001) $C_{18:2}$ and decreased (p<0.001) $C_{18:0}$ proportions in subcutaneous tissue.

This study was conducted to investigate the growth performance between six different Korean crossbred native chickens. A total of 312 one-day-old male chickens from the same paternal line with six different maternal lines were allocated into six groups (1A, 2A, 3A, 4A, 5A, and 6A) to give four replicate cages (13 birds per cage). Corn soybean meal based diets were provided as a starter (0 - 5 weeks: 20% crude protein [CP] and 3,050 kcal/kg metabolizable energy [ME]), grower (5 - 8 weeks: 18% CP, 3 and 100 kcal/kg ME) and finisher (8 - 12 weeks: 17% CP and 3,150 kcal/kg ME) diet. Chickens were able to access their respective feed and water ad libitum. In week 2, 2A had a lower body weight (p < 0.05) than that of the other groups. In contrast, in weeks 4 and 8, 2A had a higher body weight (p < 0.05). Similarly, in week 6, 2A had a higher body weight (p = 0.76) than that of the others. However, no difference (p > 0.05) was observed in the body weight after week 10. Meanwhile, 2A had a lower feed conversion ratio (FCR) than that of the other groups (p < 0.05) and a higher average daily feed intake (ADFI; p < 0.05) compared to the other groups in week 6. In conclusion, crossbred 2A had a lower growth performance in week 2; however, in weeks 4 and 6, 2A had a higher growth performance than that of the other groups. Based on this conclusion, we can use those results as a basis for further study.

체중 범위 100$\~$1000g 되는 이스라엘계 잉어에 $50\%$ 대두박을 함유하고 조단백질 함량 약 $32\%$ 되는 사료에 인산염 첨가량 결정을 위한 실험을 하였다. 그 결과 약 200g의 잉어인 제1 인산나트륨($NaH_2PO_4{\cdot}2H_2O$)을 $1.6\%$ 첨가하면 충분하다는 결론을 얻었다. 이때 잉어가 소화 흡수할 수 있는 인의 양은 총사료량의 $0.504\%$로 계산되었다. 그리고 300g 이상에서는 인의 요구양이 적게 필요한 경향은 보이지만 여기서는 정확한 자료는 얻지 못하였으므로 앞으로 크기에 따른 잉어의 인 요구양 연구가 필요하다고 사료된다. 여기에서 얻은 인 함량은 다른 연구가가 보고한 4.5g되는 작은 일본계 재래종 잉어가 필요로하는 인의 요구량 $0.6\~0.7\%$보다 적은 양이며, 이것은 어체의 크기가 다르고 또 종의 strain이 다르기 때문이라고 짐작되며, 종류별 크기별 연구가 필요하다고 사료된다.

Two experiments were conducted to evaluate nutritive value of cell mass from lysine production (CMLP) as a protein supplement for ruminants. In each experiment, animals were fed a diet containing 40% of forages and 60% of concentrates, mainly composed of rice straw and ground corn, respectively, to meet the maintenance requirements, and the diets were formulated to supply equal amounts of energy and nitrogen among treatments. In order to investigate the effect of CMLP on ruminal fermentation (Experiment 1), three Korean native goats weighing $26.1{\pm}1.4kg$ were allotted into individual cages with a $3{\times}3$ Latin square design. Each animal was fed one of three protein sources (CMLP, soybean meal (SBM), and urea). Rumen pH, bacterial and fungal counts, volatile fatty acid concentrations and acetate to propionate ratio were not significantly different among treatments. Concentration of propionate, however, was higher in SBM treatment (14.1 mM) than in CMLP (8.7 mM) or urea (9.3 mM) treatments. There was significantly more branch-chain volatile fatty acid production in CMLP (1.9 mM) and SBM (1.8 mM) treatments than in urea (1.3 mM) treatment. The number of protozoa was the highest in urea treatment, followed by CMLP and SBM treatment with significant differences. A metabolic trial (Experiment 2) was conducted to measure in vivo nutrient digestibility and nitrogen retention in Korean native goats fed CMLP and SBM. Two heavy ($35.0{\pm}1.2kg$) and two light ($25.0{\pm}0.9kg$) Korean native goats, caged individually, were used in this experiment. A heavy and a light animal were paired and supplemented with either CMLP or SBM. The animals fed CMLP showed a trend of lower total tract digestibility in all the nutrients measured; however, there was no statistical significance except for digestibility of ether extract. Nitrogen digestibility of CMLP was estimated to be about 7% units lower than that of SBM. There was a tendency for lower nitrogen retention in CMLP treatment (35.9%) compared to SBM treatment (42.3%). In summary, CMLP can be a good protein source for ruminant animals from nutritional and economic perspectives and may replace some, if not all, of SBM in a diet without losing nitrogen utilization efficiency. Further research is warranted for investigating the effect of CMLP fed with easily fermentable forage and the effective level of CMLP for replacing SBM.

A 2,172-bp full-length gene (aga-F78), encoding a protease-resistant $\alpha$-galactosidase, was cloned from Rhizopus sp. F78 and expressed in Escherichia coli. The deduced amino acid sequence shared highest identity (45.0%) with an $\alpha$-galactosidase of glycoside hydrolase family 36 from Absidia corymbifera. After one-step purification with a Ni-NTA chelating column, the recombinant Aga-F78 migrated as a single band of ~82 and ~210 kDa on SDS-PAGE and nondenaturing gradient PAGE, respectively, indicating that the native structure of the recombinant Aga-F78 was a trimer. Exhibiting the similar properties as the authentic protein, purified recombinant Aga-F78 was optimally active at $50^{\circ}C$ and pH 4.8, highly pH stable over the pH range 5.0-10.0, more resistant to some cations and proteases, and had wide substrate specificity (pNPG, melidiose, raffinose, and stachyose). The recombinant enzyme also showed good hydrolytic ability to soybean meal, releasing galactose of $415.58\;{\mu}g/g$ soybean meal. When combined with trypsin, the enzyme retained over 90% degradability to soybean meal. These favorable properties make Aga-F78 a potential candidate for applications in the food and feed industries.
