Twenty crossbred calves of $88{\pm}5.5kg$ initial live weight and 3-4 month of age were divided into two groups and fed wheat straw and concentrate to support a 500 g daily gain in body weight. Calves in the experimental group (YC) were given a daily dose of 10 ml yeast cell suspension (YC) containing live cells $(5{\times}10^9 cells/ml)$ of Saccharomyces cerevisiae ITCCF 2094. After a growth study of 122 days metabolism trials were conducted. The calves in the YC group recorded a daily weigt gain of $492{\pm}27.8g$ as compared to $476{\pm}20.1g$ in control group. There were no significant differences in feed intake, nutrient digestibility, feed/gain ratio and nitrogen retention between the YC supplemented and control groups.

The purpose of this study was to evaluate the folate nutritional status of Korean pregnant women and to investigate the relation between folate levels of maternal-umbilical cord blood, placenta tissue, and pregnancy outcomes. The study subjects consisted of 25 pregnant women who have had normal term deliveries. Dietary folate intakes of the pregnants were estimated by semi quantitative frequency questionnaire and the serum and placenta tissue folate level was measured by microbiological analysis. The total folate intakes of the pregnant women was 655.6 ${\mu}$g/d, which was 131.1% of the Korean RDA for pregnants. Maternal serum folate level was 16.18ng/ml, which was significantly lower than that of umbilical cord blood (34.98ng/ml, p<0.05). Mean folate concentration of the placental tissue was 998.0ng/ml, which was the highest compared to maternal and umbilical cord serum level. Umbilical cord serum folate level and placental tissue folate level were highly influenced by maternal serum folate level. The umbilical cord folate levels of the infant group whose birth weight was higher than 3500g were significantly higher than the group whose birth weight was less than 3500g (p<0.05). The placental folate level was significantly higher in maternal group who showed desirable weight gain during pregnancy (11 - 14kg). In conclusion, the birth weigt was related to the umbilical cord folate level and the maternal weight gain was affected by the placental folate level.

This study investigated the effects of dietary rumen-protected L-tryptophan (TRP) supplementation (43.4 mg of L-tryptophan kg^-1 body weigt [BW]) for 65 days in Hanwoo steers on muscle development related to gene expressions and adipose tissue catabolism and fatty acid transportation in longissimus dorsi muscles. Eight Hanwoo steers (initial BW = 424.6 kg [SD 42.3]; 477 days old [SD 4.8]) were randomly allocated to two groups (n = 4) of control and treatment and were supplied with total mixed ration (TMR). The treatment group was fed with 15 g of rumen-protected TRP (0.1% of TMR as-fed basis equal to 43.4 mg of TRP kg^-1 BW) once a day at 0800 h as top-dressed to TMR. Blood samples were collected 3 times, at 0, 5, and 10 weeks of the experiment, for assessment of hematological and biochemical parameters. For gene study, the longissimus dorsi muscle samples (12 to 13 ribs, approximately 2 g) were collected from each individual by biopsy at end of the study (10 weeks). Growth performance parameters including final BW, average daily gain, and gain to feed ratio, were not different (p > 0.05) between the two groups. Hematological parameters including granulocyte, lymphocyte, monocyte, platelet, red blood cell, hematocrit, and white blood cell showed no difference (p > 0.05) between the two groups except for hemoglobin (p = 0.025), which was higher in the treatment than in the control group. Serum biochemical parameters including total protein, albumin, globulin, blood urea nitrogen, creatinine phosphokinase, glucose, nonesterified fatty acids, and triglyceride also showed no differences between the two groups (p > 0.05). Gene expression related to muscle development (Myogenic factor 6 [MYF6], myogenine [MyoG]), adipose tissue catabolism (lipoprotein lipase [LPL]), and fatty acid transformation indicator (fatty acid binding protein 4 [FABP4]) were increased in the treatment group compared to the control group (p < 0.05). Collectively, supplementation of TRP (65 days in this study) promotes muscle development and increases the ability of the animals to catabolize and transport fat in muscles due to an increase in expressions of MYF6, MyoG, FABP4, and LPL gene.

Aiming at the total 200 pregnant women including 150 ones registered with the Health Center of Chung Ku District and 50 ones registered with the Health Center of Mapo District, we have conducted a research study of the socio-medical characteristics, maternal child health, and the status of nutritional intake which has utilized the application of convenient method for the study of nutritional status, during the period of April 20 to May 25, 1983. And we have obtained the following conclusions: 1. Regarding age distribution, the pregnant women aged from 26 to 30 were most numerous, which was 54.0%. The percentage of women who experienced the first pregnancy was 12.0% and the percentage of those who experienced the second pregnancy was 37.0%, which was the highest. Regarding the weeks of pregnancy of the pregnant women, the first trimesterr was 11.5%, the second trimester 30.0%, and the third trimester 58.6%. 2. Regarding academic achievements, the pregnant women who graduated from middle schools reached 43.5%, which was the highest percentage. Regarding economic status, the pregnant women who owned their own houses were only 21.0%. And the pregnant women whose monthly income was from 300,000 won to 400,000 won were 40%, which was the most numerous. 5. The women above 15 years old who experienced the first menstruation were 84.0%. And those who experienced abortion were totally 54.4%. and 35.5% among those women experienced artificial abortion. 4. 70.5% of the pregnant women said that their health condition was excellent, 24.5% felt subjective complaints, and 5.0% specially received medical consultation for their diseases. 5. 82.0% received prenatal care, but 60.5% regularly received prenatal care. 68.0% received the education for nutrition and only 19.5% regularly received the education for nutrition. 6. Regarding the family composition, the families consisting of two generations were 47.0%, which was the most numerous. 97.5% of the preparation for meals was conducted by housewives. They said that they did not lack time for meal preparation. 7. 94.9% of the pregnant women said that they had eaten as in ordinary times during their pregnancy. 25.5% said that there were tabooed foods. Tabooed foods are chiefly pork, chicken, milk, and eggs. 68.0% don't drink milk during pregnancy, 32.5% take the intake of vitamins, and 20.5% take iron supplement. 8. The average amounts of the intake of protein, fat, and carbohydrate of a pregnant women are 49.3gm, 29.4gm, and 205.1gm respectively, which showed the phenomenon in which the amount of the intake of nutrition increased as the weeks of pregnancy increased. The average amount of the intake of salt was 14.2gm. 9. Regarding the hemoglobin value of all pregnant women, those whose hemoglobin value was less than 11.0gm were 66.5%, those whose hemoglobin value was 11 to 12 gm were 16.5%. and those whose hemoglobin value was above 12gm were 17.0%. The pregnant women whose hemoglobin value was less than 11.0gm in the first trimester of pregnancy, in the second trimester, and in the trimester were 81.8%, 62.8%, and 64.9% respectively. This shows that the phenomenon of anemia increased as the weeks of pregnancy increased 10. Regarding physical development of a pregnant woman during prenatal period, the height and weight were $156.7cm{\pm}14.1$ and $51.1kg{\pm}58$ respectively. When the standard increase of a prenatal weigt gain is set as 100%, the women over the range of 100% were 28.0% and the women under the range of 80% were 37.0%.
