In Experiment 1, microbial assays were conducted on 57 feed ingredient samples to determine the content of total folic acid using Lactobacillus casei(ATCC 7469). Folic acid contents of feed samples pretreated with conjugase, ${\alpha}$-amylase, and a mixture of protease(Pronase)were corn, 09${\pm}$1.18($\pi$g${\pm}$SD); fish meal, 23.05${\pm}$1.27; milo, 29.34${\pm}$0.55; bakery meal, 25.80${\pm}$6.93; meat and bone meal, 56.76${\pm}$4.97; wheat middlings, 85.14${\pm}$2.56; and soybean meal, 193.97${\pm}$3.98. Experiments 2 and 3 were conducted to determine the effects of dietary supplemental folic acid and methionine on the performance of starting broiler chicks for 18 days. Four levels of dietary folic acid(0.24. 0.54,1.14 and 2.34mg/kg) and four levels of dietary methionine(0.45, 0.53,0.61, and 0.69%) were fed in a factorial design. The basal diet was based on corn, isolated soybean protein, meat and bone meal, and fish meal. It contained adequate amounts of all nutrients except methionine and folic acid in both experiments. Increased growth rate was observed in chicks fed the basal diet supplemented with either folic acid or methionine. Total dietary folic acid and methionine plus cysteine requirements for optimum growth were estimated to be 1.80 mg/kg and 0.89% in Experiment 2, and 1.47 mg/kg and 0.91% in Experiment 3, respectively. There were interactions between dietary folic acid and methionine on weight gain in both experiments. Chicks fed diets containing 2.34 mg folic acid /kg tended to display slow growth rate in both experiments. There was a significant linear feed conversion response to folic acid in Experiment 2, and a significant quadratic feed conversion resuonse to methionine in Experiment 3. There were both linear and quadratic liver folic acid responses to dietary folic acid in both experiments. There was no indication that dietary methionine had any effect on liver folic acid content. The incidence of tibial dyschondroplasia increased with increasing supplemental methionine, but were no significant differences detected at 5% level.

The influence of supplementing diets with various levels of organic zinc (OZ) on the performance, meat quality attributes, and sensory properties of broiler chickens was investigated. A total of 3,200 1-d-old female broiler chicks were randomly allotted to 16 floor pens (replicates) with 200 birds per pen. A corn-wheat-soybean meal basal diet (control) was formulated and 20 ppm OZ (20 OZ), 40 ppm OZ (40 OZ), or 80 ppm OZ (80 OZ) was added to the basal diet to form four dietary treatments with four replicates per treatment. Live performance of broiler chickens, meat quality, and sensory properties were evaluated. The results showed no significant difference among the treatments for live performance of broiler chickens. Significant increases (p<0.05) in thigh skin epidermis and dermis thickness were shown in the OZ supplementation groups; however, no effect of OZ on the thickness of back skin epidermis or dermis was found. Dietary OZ levels did not affect the pH of breast and thigh meat or the water holding capacity (WHC) of thigh meat, but the WHC of breast meat increased significantly (p<0.05) when birds were fed 40 OZ and 80 OZ. Results of a sensory analysis showed no differences among the dietary treatments. In conclusion, dietary OZ did not affect live performance or sensory properties of broiler chickens but did increase the WHC of breast meat and thickness of skin layers; thus, improving carcass quality in broiler chickens.

A Survey was conducted to identify patrcis' eating behavior at the buffet styled restaurant during dinner time. The average frequency of taking food was 4.1±0.9 and this was statistically significant by age group. The frequency of taking food after satiety was 1.2±0.8. From the menu, 15 seafood items were the most popular which were chosen more than twice. The average of consumed food items was 24.9±8.9 out of 198. The average seafood items which were chosen by each individual was 5.8, desert items was 4.5, salad items with dressing was 4.2. The total weight of the consumed food was 954±365.1g. Mostly gruel, soup and saled chosen the first time. Alcholic beverages and drinks were chosen also first time. Seafood was chosen the 1.2 times and meat was chosen the first, second, and third time. Rice and soup. bread and noodles were chosen the second and third time. Desert was chosen the third time. The consumption of calories and nutrients were compared with the Korean Recommended Dietary Allowances. The average consumption of calories was 49.6% Korean RDAs, protein 71.4%, vitamin A 65.0%, thiamin 74.3%, riboflavin 71.8%, niacin 89.8%, ascorbic acid 72.7%, iron 68.1%, and calcium 108.3%. In one meal, the data shows over eating. The caloric consumption of desert was 275.5Kcal and seafood was 174.1Kcal. The protein consumption of seafood was 23.5g and meat was 7.5g. According to this research, customers have a lot of good chances to be exposed to the variety of food. This is desirable to correct the food habits with a experience. On the other hand, excessive food consumption is a problem. Therefore we suggest the provision of nutrition information about desirable order of eating a meal and the health problems due to overeating. We expect other research of nutritional evaluation in a meal in the different foodservice systems to be made in the future.

An experiment was conducted to investigate the effects of dietary supplementation of feather meal (FM its) digests on the performance of broiler chicks and taurine content in broiler meat. A total of 1,000 broiler chickens were assigned to five dietary treatments : Control, FM diet(FM), FM+pyridoxine(FM+Pyridox), H$_2$O$_2$ treated FM diet(H$_2$O$_2$-FM) and enzyme treated FM diet (Enzyme-FM). Treated diets were supplemented with FM or FM digests at the level of 5 % to the control diet. During the stater period, weight gain of chicks fed FM+Pyridox was significantly higher(P<0.05) than those of the other FM or FM digest treatments but was not different from the control. Weight gam of overall period were not significantly different among treatments. Feed intake of the control was greater than that of FM or FM digest treatments. Feed conversion ratio(feed intake/gain) of chicks fed FM and H$_2$O$_2$-FM were significantly higher than those of Enzyme-FM and FM+Pyridox, but were not significantly different from the control. Taurine contents of leg and breast mucle were significantly (P<0.01) different among treatments but those of liver were not significantly different. Taurine content of FM+Pyridox was highest in both leg and breast muscle. It was 85 % higher in leg muscle and 15 % higher in breast muscle than that of the control. Sensory evaluation data showed significant but not consistant responses in various parameters. FM + Pyridox treatment showed highest score in aroma of raw leg muscle of male and in juiciness and tenderness of broiled breast muscle of male chickens. Control group showed highest color score in raw leg muscle of female and lowest overall acceptability score in broiled breast and leg muscle of male chicken. It is concluded that taurine can be enriched especially in broiler leg meat by 5 % FM diet supplemented with pyridoxine.

This study was to investigate the food habits and the dietary behaviors of university students. Questionnaires were completed by 492 students in five different departments. The data were analyzed by SAS program. The results are summarized as follows: Fifty(10.2%) of respondents were vegetarians, 81(16.4%) were heavy meat eaters and all the others were light meat eaters. All students had their biggest meal at supper. Three hundred and ninety-three(79.9%) of the respondents usually had rice for breakfast. Three hundred -sixteen(64.2%) ate 3 meals a day, 155(31.5%) ate 2 meals and all the others ate 1 meal or more than 3 meals. The length of mealtime was 30 minutes in 268(54.5%), 10 minutes in 209(42.5%) and more than 1 hour in all the others. Respondents considered taste the most important meal factor with nutrition, hygiene, and amount ranked accordingly. A majority(63.0%) of respondents ate occasionally ate between meals, while 28.1% snacked frequently, and 8.9% ate no snacks. Although nutrition dept. students had studied nutrition subject, some results of nutrition dept. students were desirable and others were undesirable in dietary behaviors. Therefore they should have a nutritional education program to improve their food habits and the dietary behaviors for students' health. And nutritional education program should be organized practically and systematically.
