For the purpose of the better dietary management and to empahsize of importance in nutrition education for 552 students at the dormitories, College of Agriculuture, Seoul National University, the dietary survey was conducted for each consecutive seven days, from March 7th to 13th at the boy's dormitory, from March 14th to 20th at the girl's dormitory, respectively. In comparison the average caloric and nutrient intake per caput per day at the both, girl's and boy's dormitory with the recommended dietary allowances for age of 25, the intake of calorie, and all nutrients except riboflavin were over the allowances for the boy, while the caloric intake be the girl was considerably below the allowance. But it is meant that only 150 calories was actually deficient in comparison with the figure of the average energy consumption determined for the girls at the dormitory of the Sook-myung Woman's University, whose pattern of living was quite similar to those of the girls at this college. Except iron and ascorbic acid, all other nutrients were deficient for the girls. The calories in the form of protein of a diet taken by the boy was 12.9% and that by the girl was 12.8%. Protein quality of the diet taken by boy scored 70 while that by the girl scored 79. NDp Cal% of the diet taken by the boy was 7 and that by the girl was figured out to be 8. Therefore, calculated reference protein taken by the boy was 55.8 grams and that by the girl was 36.9%. Though it is generally recommended that at least ⅓ of the protein should come from animal sources, it was apparent by this survey that providing 1/5 of the protein from animal sources with remaining part of high quality vegetable protein foods in the adequate mined diet would give satisfactory results for both girl and bow students. This was clearly demonstrated by the recommended reference protein and NDp Cal% met. Significant difference between boys and girls in the average consumption of seasonings was found. In consumption per das of seasonings, boy used 1.5 grams of red pepper powder which means they used 15 times more of red pepper than girls did. Kochujang was used 13 grams by boy-students which was as high as 21 times of that of the girl. Total salt intake by the boy was 34 grams while the girl consummed 23 gram.. It is obviously recognized that boys prefer more peppery and salty flavor than girls do. To reduce the amount of protein consummed and to improve the quality of protein food, increase of riboflavin rich food and increase of fat intake in place of grain intake are recommendable to the boy. For the girl's diet, consumption of grains, particularly more intake of barley may be recommendable to meet the B group of vitamins allowances as well as the caloric allowance. The use of more serving of yellow green vegetables is needed to the girl.

This experiment was carried out to investigate the effects of feeding antibiotic, enzymes, yeast culture and probiotics on the growth performance, nutrient digestibility and antibiotics residue in Israeli carp. A total of 253 Israeli carp weighing about 300 g/fish were allotted to 6 groups; control, Oxytetracycline (OTC), Nosiheptide (NH), enzyme, yeast culture and probiotics. Each group had 3 replications consisting of 14 fishes. Feeding trial were performed for five weeks. A metabolic vial was carried out by indirect methods using diets with Cr₂O₂. Tire residue of antibacterials agent in muscle was evaluated. The results obtained are as Follows: 1. Supplementation with NH, yeast culture and probiotics showed 16.5, 10.8, and 23.7% improvement in teed efficiency, respectively (p$lt;0.05). 2. NH, yeast culture and probiotics increased protein availabilities by 2.4, 1.3 and 2.0%, respectively, while NH and probiotics increased NFE digestibilities by 13.9 and 16.8% compared to the control, respectively (p$lt;0.05). There was no significant (p$gt;0.05) differences in amino acid digestibility among treatments. 3. OTC residue in muscle was less than the detectable limit (0.5 ppm).

A series of experiment was conducted to study effects of the partial substitution of Canadian barley (0, 10, 20, 30, 40%) for corn in the rations of growing chicks. The growth rate, feed intake, feed efficiency, mortality, nutrients utilizability and economic return among 5 treatments were compared with 500 birds of growing chicks of laying Shaver strain(Starcross) for a period of 21 weeks. The results obtained are summarized as follows: 1. Although the protein content of Canadian barley (12%) was higher than that of local barley, the amino acids composition of Canadian barley was similar to that of local barley. Throughout the total experimental period the growth rate was not affected by the level of barley used in the starter, grower and pullet developer diets. 2. It was found that there was no statistical difference in feed intake, feed efficiency and mortality among 5 treatments. 3. Present data revealed that the feed cost required per kilogram of body weight gain was not affected by the level of barley incorporated into the diets of growing chicks. 4. Metabolizability of dry matter, protein, fiber and nitrogen free extract was not affected by the level of barley, although the fat utilizability was significantly (p<0.01) improved as the level of barley was increased. It is concluded that the partial substitution of barley for corn up to 40% level would have no adverse effects on the growing performance of the chicks.

Two experiments with 32 sheep were conducted to study the effects of feeding the same amount of diet per day at different meal frequencies on ration digestibility, energy utilization, rate of gain, body composition and efficiency of gain. The results obtained are as follows: (1) The ingestion by sheep of the same amount of feed per day in 8 meals, 1 meal plus 7 ruminal inflations-deflations, and in 1 meal caused no different effect in the digestibility of the nutrients and energy, or the ME value of the diet. (2) Heat production per unit of metabolic size per unit of dietary, intake was markedly lower for sheep ingesting 8 mears or administered 1 meal plus 7 ruminal inflations-deflations per day than for sheep fed 1 meal per day. (3) Body weight gain was significantly greater by sheep fed 8 meals per day or 1 meal plus 7 ruminal inflations-deflations than by those fed 1 meal per day. However, the gain in DM and energy of wool was not affected by frequency of meals. (4) Sheep ingesting 8 meals or administered 1 meal plus 7 ruminal inflations-deflations per day gained body protein, fat and energy at a more rapid and efficient rate than sheep fed 1 meal per day. (5) Sheep fed 8 meals per day gained greater proportion of fat, protein and ash in the gained portion of the bodies than did 1 meal fed sheep. (6) An attempt was made to establish the possible explanations by which the frequency of ingesting meal exerts its effects.

This experiment was performed to investigate the effect of the frequency of meals on the methbolism and the body composition of rats when equal amount of purified diet was ingested. Thirty approximately days old rats weighting 290g and thirty-two about 40 days old rats weighing 180g were employed for the period of 34 days. Rats fed (10 to 15 meals per day) and two-meal per day were pair-fed and equal amount of die was fed to each rat in pair. The experienced results obtained are summarized as follows: 1. Frequency of meal did not exert any effect on the body weight gain. However, rats fed two-meal per day gained significantly (p$lt;0.005) more fat and energy than ad libitum group. The rate of gain of proteia in ad libitum group was higher than that of two-meal group. No difference was observed for the mineral deposition of rat body. 2. From the preparation of rat liver it was found that the activity of glucose-6-phosphate dehydrogenase was much higher for the rats fed two-meals per day than those fed ad libitum. Therefore, it is suggested that the metablic pathway of carbohydrate for two-meal group has been shifted from glycolysis to Hexose Monophosphate Shunt and produced more NADPH which would be the essential cofactor of fatty acids synthesis. 3. The rate of excretion of urinary nitrogen for two-meal group was significantly (p$lt;0.005) higher than that of ad libitum group. It is apparent that considerable amount of over-loaded amino acids by feeding two-big-meal daily could not be used for the protein biosynthesis all at once and excreted following deamination through urine. The residual carbon chain could be served as a precursor of fatty acids synthesis. 4. The heat production rate of rats fed two-meal group was significantly (p$lt;0.005) lower than that of ad libitum group, It seems possible that the activity of thyroid gland (and consequently BMR) can be depressed by the frequency of meal.

This experiment was conducted to study the effects of dietary protein and energy level on the body composition of broiler chicks. To analyze the chemical composition of chicks, 27 birds at ten week-age were sacrificed by the standard slaughter analysis method at the end of this experiment. The results obtained from this study for the body composition may be summarized as follows; 1. No significant difference was observed in the content of protein on empty body basis. However, under the condition of dried body basis, the protein content was increased as the level of protein increased. 2. The level of dietary energy had no effect in the content of fat on the basis of empty body weight. However, fat content of chick bodies was significantly (p$lt;0.05) increased as the dietary protein level decreased. It was noted that high-energy and low-protein ration tends to increase (p$lt;0.01) body fat. 3. No significant difference in ash content of carcass was observed among the treatments. 4. Dry matter and water content of the carcass was not significantly affected the level of dietary protein and energy.
