This study aimed at the effect of carbohydrate level on serum glucose and lipid in Korean female 300 NIDDM patients. Mostly NIDDM appears in 50-64 years. As carbohydrate level increased, nutrient intakes increased. Most carbohydrate intakes were polysaccharides. High carbohydrate diets made blood glucose level increased. But high carbohydrate-fiber diets result lowering effect on serum LDL /HDL-cholesterol ratio and triacylglycerides. In conclusion, NIDDM patients need regular exercise and total energy intake balance. High carbohydrate-fiber diets are recommendable.

A 16-wk feeding trial was conducted to investigate the proper feeding regimen on the performance of Korean Native Chicken(KNC) consuming broiler diets. Commercial KNC are normally fed 3 kinds of diets during their life span, i. e., starter(S, 0 to 3wk of age), grower(G, 4 to 7wk of age), and finisher(F, 8 to l6wk of age) diets. In this trial, four feeding regimen were employed:T1(S-G-F), T2(S-G-G), T3(S-S-F), and T4(S-F-F). Day-old 360 KNC were randomly allotted to 12 pens: three pens per treatment, and 30 birds per pen. At the end of the trial, the BW of T2 was significantly better than that of T3(P<0.05), and T1 and T4 were intermediate. No significant difference were found in feed intake, feed conversion ratio, and viability among treatments. It appears that, in terms of BW gain, the T2 is the recommendable feeding regimen for KNC consuming broiler diets.

This study was conducted to evaluate the use of tuna by-product meal (TBM) as a substitute for fishmeal in juvenile Korean rockfish (Sebastes schlegeli) diets. Five isonitrogenous (52% crude protein) and isocaloric (4.9 kcal/g) diets were prepared. Control diet (Con) was formulated to contain brown fishmeal, whereas 25, 50, 75, and 100% of fishmeal was substituted with the same percentage of TBM in the TBM25, TBM50, TBM75, and TBM100 diets, respectively. Three replicate groups of fish (initial weight, $29.5{\pm}0.6g$) were fed one of the five diets for 12 weeks. The mean weight gain of fish fed the Con and TBM25 diets was significantly higher than that of fish fed the TBM100 diet (P < 0.05), but it was not significantly different from the weight gain of fish fed the TBM50 and TBM75 diets. The feed efficiency and protein efficiency ratios of fish fed the Con diet were significantly higher than those of fish fed the TBM100 diet (P < 0.05), but were not significantly different from those fed the TBM25, TBM50, and TBM75 diets. The TBM25, TBM50, TBM75, and TBM100 diets had significantly (P < 0.05) lower incidence cost and higher profit index than the Con diet. These results suggest that the tuna by-product meal used in this study could replace up to 75% of fishmeal protein in the diet without reducing growth and feed utilization in juvenile Korean rockfish weighing 29-53 g. By considering feed cost, the TBM 75 diet is recommendable for Korean rockfish farming.

This study was performed to investigate nutritional effect and the utilization possibility of rapeseed oil which could replace the imported edible oils and oil crops. The proximate compositions of a recommendable cultivar(Mokpo Dangyo 19) and a native kind(Asahi) and the characteristics of these rapeseed oils were analyzed. The animal experiment of these rapeseed oils was carried out during 8 weeks of growing periods after weanling. Forty male weanling Sprague-Dawley rats were randomly assigned to 3 diet groups of Dangyo 19 oil, Asahi oil and commercial Soybean oil. Mokpo Dangyo 19 variety contained more lipids than Asahi variety by 8% and there was no difference in physiochemical characteristics between Dangyo 19 oil and Asahi oil except that erucic acid was contained little in Dangyo 19 oil but 50% in Asahi oil. Body weight gain, FER(Feed efficiency ratio) and PER(Protein efficiency ratio) of rats fed Dangyo 19 oil were higher than those of rats fed Asahi oil and organ weights such as liver, kidney and epididymal fat pads weights of rats fed Dangyo 19 oil were significantly higher(P<0.05) thanthose of rats fed Asahi oil. the apparent digistibility of total diet and total lipid were higher in rats fed the diets containing Dangyo 19 oil than Asahi oil. The content of total lipid in heart in heart were not significantly different with dietary oil kinds. The content of total lipid in liver increased with age in all rapeseed oil groups.

Effects of dietary Scutellaria baicalensis extract (SBE) on growth, feed utilization and challenge test of olive flounder (Paralichthys olivaceus) were determined. Six hundred thirty fish averaging 5.0 g were distributed into 18, 180-L tanks. Six experimental diets were prepared in triplicate: SBE-0, SBE-0.5, SBE-1, SBE-2, SBE-3 and SBE-5 diets containing SBE at the concentrations of 0, 0.5, 1, 2, 3 and 5%, respectively. Fish were hand-fed to apparent satiation twice a day for 8 wks. At the end of 8-wk feeding trial, ten fish from each tank were infected by Edwardsiella tarda for challenge test. Survival and weight gain of fish were not affected by dietary concentrations of SBE. However, specific growth rate of fish fed the SBE-2 diet was higher than that of fish fed the SBE-0, SBE-1, SBE-3 and SBE-5 diets. Neither feed efficiency nor serum chemical composition of fish was affected by dietary concentrations of SBE. The cumulative mortality of fish fed the SBE-0 diet was 100% at 96 h after E. tarda infection, but 77 to 87% for fish fed the other diets. Dietary inclusion of 2% SBE appears to be recommendable to improve specific growth rate of fish and SBE had the potential to mitigate mortality of fish at E. tarda infection.

Effects of the commercially available or formulated extruded pellets (EP) and raw fish-based moist pellet (MP) on growth and body composition of flounder Paralichthys olivaceus L. were evaluated on commercial scale for 10 months. Survivals of flounder fed the MP, EP 1 and EP3 were not significantly different from those of fish fed the EP2 or EP5, but significantly (P<0.05) higher than that of fish fed the EP4. Weight gain of fish fed the MP was not significantly different from that of fish fed the EP3 and EP5, but significantly (P<0.05) higher than that of fish fed the EP1, EP2 or EP4. Improvement in weight gain of flounder fed the high lipid diets (EP1, EP2, EP3) compared to low lipid diet (EP4) in the $55\%$ protein level, and weight gain of fish fed the high lipid diet (MP) compared to low lipid diet (EP5) in the $61\%$ protein level indicated protein-sparing effect of lipid. FER for flounder fed the EP3. which was not significantly different from that for fish fed the EP1 or EP5 was significantly (P<0.05) higher thar. that for fish fed the EP2, EP4 and MP. FER significantly (P<0.05) changed over time. CF of flounder fed the MP was significantly (P<0.05) higher than that of fish fed EP1 or EP4. Moisture content of dorsal muscle in flounder fed the EP2 was significantly (P<0.05) higher than that in fish fed the EP1 or EP4. Crude protein content of dorsal. muscle in flounder fed the EP1, EP4 and EP5 was significantly (P<0.05) higher than that in fish fed the EP2. How- ever, crude lipid content of dorsal muscle, and moisture, crude protein and crude lipid content of liver in flounder was not significantly different among the diets. In considering performance of flounder, it can be concluded that the use of EP3 and EP5 is more recommendable than the MP, which commonly used in flounder farm.

육성기 넙치 사육용으로 부상배합사료 및 생사료의 사육효과를 비교하기 위하여 2회에 걸친 사육실험을 실시하였다. 실험 1에서는 평균체중 115 g의 넙치를 5종류의 실험EP ($EP1{\sim}EP5$v와 생사료(MP)로 78일간 사육 실험하였으며, 실험 2는 양식현장에서 평균체중 137 g의 넙치를 실험 1에 사용한 5종류의 EP ($EP1{\sim}EP5$), 시판사료(EP6) 및 EP4와 EP6에 물과 각종 영양소를 흡착시킨 2종류 흡착-습사료(MEP4 및 MEP6)로 80일간 사육 실험하였다. 사육실험 결과, 실험 1에서 증중율은 모든 EP 실험구가 MP 실험구와 유의한 차이가 없었으며, EP4는 MP에 비하여 더 높은 값을 보였다. 사료효율은 EP4 실험구가 다른 실험구보다 유의적으로 높은 결과를 보였다(P<0.05). 등근육의 간과 수분함량 및 간의 지질함량은 실험구간에 유의한 차이를 보였다. 실험 2에서는 생존율은 $89{\sim}99%$의 범위로 양호한 결과를 보였다. 증중량은 EP4와 MEP4 실험구가 가장 높은 값을 보였으며, 그 다음으로 EP3과 MEP6 실험구가 양호한 결과를 보였다. 사료효율은 모든 실험구에서 108% 이상으로 양호하였으며, EP4, MEP4 및 MEP6에서 높은 값을 보였다. 이상의 결과들로부터, $114{\sim}350\;g$인 넙치에게 생사료를 기초로 제조된 MP를 공급하는 것 보다 영양소 균형이 잘 갖춰진 EP를 공급하여도 좋을 것으로 보이며, EP 공급시 물과 다른 영양소의 흡착과정은 불필요할 것으로 판단된다. 또한, MP와 상업용 EP 실험구에 비해 양호한 성장 결과를 보인 EP4는 MP 대체 실용사료로서 사용될 수 있을 것으로 기대된다.
