To examine the effects of Euglena rubra (E. rubra) feeding on Nile tiapia, Oreochromis niloticus were fed diets containing dried powder of E. rubra at 0.5 or 2% for 4 weeks. Growth, selected hematological and non-specific immune parameters were assessed at 2 and 4 weeks. There were no significant changes in body weigh gain and erythrocyte levels. However a significant and diet E. rubra level-related decrease in leukocyte level was noted. Significant increases were observed in respiratory burst activity (nitroblue tetrazolium reduction) and lysozyme activities following E. rubra feeding. These results indicate that E. rubra could be beneficial to fish, but excess feeding could toxic.

우리나라의 수산 양식과 어로기술은 세계적 수준임에도 불구하고, 가공기술은 상대적으로 낙후되어 있다. 수산가공품은 냉동품, 통조림, 염장식품(젓갈), 연제품(어묵) 등이 대부분으로, 특히 부가가치가 가장 높은 고품질의 수산 건제품은 매우 적다. 이러한 문제는 단적으로 건조기술의 부족에 기인한다고 사료된다. 본 논문은 부패하기가 쉽지만 향후 대량 생산이 계획되어 있는 고가 수산물의 고품질 건조 가공이 기능하게 하기 위한 에너지 절약형 진공건조장치의 건조열전달특성에 관하여 수행한 실험적 결과를 보고한 것이다.

We designed a 16-week feeding experiment to test the effects of dietary supplementation with distillers' dried grain (DDG) on the growth, feed utilization, and body composition of juvenile muddy loach Misgurnus anguillicaudatus. Seven isonitrogenous and isocaloric diets were formulated to contain 0% DDG (Control); 10%, 20%, and 30 % DDG from rice (diets RM10, RM20 and RM30); and 10%, 20%, and 30% DDG from rice and wheat flour (diets RWM10, RWM20 and RWM30), respectively. Three replicate groups of juvenile muddy loach averaging $1.5{\pm}0.10$ g were fed one of the diets to satiation twice daily. Survival of juvenile muddy loach fed the RWM20 and RWM30 diets was higher than that of the control group (P<0.05), while weight gain tended to decrease when fish were fed diets containing DDG. Weight gain of fish fed the RWM10 diet was greater than that of fish fed other diets, but the RM30 diet resulted in less weight gain than did the control (P<0.05). The feed and protein efficiency ratios of fish fed the RM10, RM20, RM30, RWM10, RWM20 and RWM30 diets were all similar to the control (P>0.05). Neither daily feed intake nor proximate composition of the whole body was affected by dietary DDG (P>0.05). The compositions of isoleucine, leucine, lysine, threonine, and valine were all elevated in fish fed the RM30, RWM10, RWM20 and RWM30 diets relative to those of other groups (P<0.05). In contrast, methionine + cystine and phenylalanine + tyrosine were all lower in fish fed the RM30, RWM10, RWM20 and RWM30 diets, as compared to those of other groups (P<0.05). Our results suggest that DDG is suitable as a partial replacement for soybean meal and wheat flour, and could be used at a rate of up to 20% for rice, or 30% for rice and wheat flour, for optimum growth performance of juvenile muddy loach.

The Gwugonsiuebang is a book of Korean woman's life in the Yi dynasty which published I 1653 by Mme. Jang. I have studied the food habits of the Yi dynasty that wrote in Gwugonsiueband as following. The staple foods are Guksu (wheat vemicell as like western noodles) 5, Mandu (bun stuffed with seasoned meat and vegetables) 6 kinds in this book. the side dishes are Guk (soup) 8, J'm (steamed meat or fish) 6, chae6, Nooruemi 5, Hyae (sliced raw fish) 3, Jockpyun (jellied beef soup) 3, Jockgall (salted sea food) 2, Jock (skewer or broach) 2, jihee 2, Sun (Steaming of stuffed vegetable) 1, Bockuem (saute) 1, Jon (pan fried fish) 1, Gui (meat or fish grilled with seasoning) 1, and the other 13 kinds. The desserts are D,ock (Korean rice cake) 11, jabgwa 8, Beverages 5 kinds and Jungwa 1 kind. The alcohol and fruits wine are 51 kinds. The alcohol and fruits wine are 51 kinds. The seasonings are Soybean sauce, oil, Sesamol oil, pepper, Ginger, Garlic, Vinegar, Wine, Salt, Bean paste etc. Raw materials of Guksu, Mandu, D'ock, Jabgwa, Beverage, Wine, vinegar are all carbohydrates. It shows that a tendency of Korean people too much take a carbohydrates. Now and then, there are no special difference of winter over pass for vegetables, fruits, dried beef, dried fish and salt fishes. In yi dynasty, there are 62 kinds of table ware and cooking kitchen utensils, but many of them come to uselessness. 19 kinds of measuring unit are very non-scientific because that is not by weight but by bulk or volume. There are many food making terms which are 198 kinds of prepared cooking term, 11 kinds of cutting term and 20 kinds of boiling term. And 10 kinds of expression of taste can see this book.

One growth trial and one digestibility trial were conducted to evaluate the nutritional value of HP300, a commercially processed soybean meal product for weanling pigs. Dried whey, fish meal and/or full fat extruded soybeans (FFES) as well as portions of soybean meal (SBM) were replaced with HP300 in weanling pig diets. The objectives were to investigate the effects of HP300 on growth performance, digestibility, ileal amino acid digestibility and blood amino acid concentration in weanling pigs. One hundred and twenty crossbred $(Duroc{\times}Beijing\;Black{\times}Landrace)$ pigs weaned at 28 days of age were used in the growth trial. The pigs were randomly allocated to five treatments, with three pens per treatment and eight pigs per pen. The trial duration was 28 days. The control (CTRL) diet contained no HP300; in treatments 2, 3 and 4, dried whey and fish meal were replaced by 3.0%, 7.5% and 10.5% HP300; in treatment 5, full fat extruded soybeans were replaced by 10.5% HP300 plus soybean oil to attain the same metabolic energy content as FFES. Five T-cannulated barrows were used in a digestibility trial with a $5{\times}5$ Latin square design to determine nitrogen retention and amino acid ileal digestibility of HP300 used alone or mixed with other ingredients. The results indicated that replacement of dried whey, fish meal, full fat extruded soybeans and a part of the soybean meal with HP300 in piglet diets improved average daily gain and feed conversion ratio (p < 0.05). There was a trend toward improved DM, crude protein and amino acid ileal digestibilities and improved protein and amino acid ileal digestibilities and improved protein net availability with the use of HP300 in swine diets.

This study was designed to test the effects of dietary distillers dried grain (DDG) level on the growth performance, feed utilization, body composition and antioxidant activity of juvenile red seabream (Pagrus major). Six isonitrogenous and isocaloric diets were formulated to contain 0%, 5%, 10%, 15%, 20%, and 25% DDG from rice (designated as DDG0, DDG5, DDG10, DDG15, DDG20, and DDG25), respectively. Juvenile red seabream averaging $10.1{\pm}0.05g$ were randomly distributed into 400-L tanks in a flow through systems. Three replicate groups of fish were fed one of the experimental diets to visual satiation two times a day for 10 weeks. Survival, weight gain, feed efficiency, protein efficiency ratio and hepatosomatic index of fish were not affected by dietary DDG levels (p>0.05). Proximate and amino acid composition of whole body in juvenile red seabream were not affected by dietary DDG levels (p>0.05). Plasma content of total protein, glucose, cholesterol, glutamic-pyruvic transaminase, phospholipid and triglyceride were not affected by dietary DDG levels (p>0.05). 1, 1-Diphenyl-2-picryl-hydrazyl radical and alkyl radical scavenging activities in plasma and liver of fish were not affected by dietary DDG levels (p>0.05). The results of this experiment suggest that DDG has the potential to replace plant origin ingredients such as wheat flour and corn gluten meal and could be used up to 25% in diet without incurring negative effects on the growth performance of juvenile red seabream.
