Objective: Adequate vitamin and trace mineral intake for pigs are important to achieve satisfactory growth performance. There are no data available on the vitamin and trace mineral intake across pig producers in China. The purpose of this study was to investigate and describe the amount of vitamin and trace minerals used in Chinese pig diets. Methods: A 1-year survey of supplemented vitamin and trace minerals in pig diets was organized in China. A total of 69 producers were invited for the survey, which represents approximately 90% of the pig herd in China. Data were compiled by bodyweight stages to determine descriptive statistics. Nutrients were evaluated for vitamin A, vitamin D, vitamin E, vitamin K, thiamine, riboflavin, vitamin B₆, vitamin B₁₂, pantothenic acid, niacin, folic acid, biotin, choline, copper, iron, manganese, zinc, selenium, and iodine. Data were statistically analyzed by functions in Excel. Results: The results indicated variation for supplemented vitamin (vitamin A, vitamin D, vitamin E, vitamin K, vitamin B₁₂, pantothenic acid, niacin, and choline) and trace minerals (copper, manganese, zinc, and iodine) in pig diets, but most vitamins and trace minerals were included at concentrations far above the total dietary requirement estimates reported by the National Research Council and the China's Feeding Standard of Swine. Conclusion: The levels of vitamin and trace mineral used in China's pig industry vary widely. Adding a high concentration for vitamin and trace mineral appears to be common practice in pig diets. This investigation provides a reference for supplementation rates of the vitamins and trace minerals in the China's pig industry.

Elevated maternal plasma homocysteine concentrations have been associated with adverse pregnancy outcomes. Serum homocysteine levels may be affected by the MTHFR genotypes and the nutritional status of B vitamins including vitamin $B_2,\;B_6$, folate and vitamin $B_{12}$. We investigated whether postnatal growth measurements were influenced by maternal MTHFR genotypes and their mid-pregnancy serum vitamin B and homocysteine levels. In 130 pregnant women of 24-28 wks of gestation, the MTHFR genotypes, serum B vitamins and homocysteine concentrations were analyzed. Physical growth status was assessed in their offsprings by measuring height, weight, and head and chest circumferences from birth up to 24 months. Serum homocysteine levels were higher in the subjects with T/T genotype than those with the C/T or C/C. Heights and head and chest circumferences of offsprings from the T/T mothers were significantly lower than those from the C/C or C/T mothers only when the serum homocysteine levels were above the median. The mean height of offsprings from the T/T mothers was significantly lower than those from the C/C and C/T mothers. The mean weight and head circumferences of offsprings born from the mothers whose mid-term pregnancy PLP levels were in the lowest quartile was significantly lower than those from mothers in the highest quartile. Heights and head circumferences of offsprings from the T/T mothers were significantly lower than those from the C/C or C/T mothers only when the serum FAD levels were in the lowest quartile. These results suggest that postnatal growth up to 24 months may be influenced by the maternal C677T MTHFR genotypes, and mid-pregnancy serum homocysteine and vitamin B status.

The objective of this was to investigate the technical feasibility of producing toxicant-free by germination. To this end, rapeseed(Brassica napus L.) was germinated at $25^{\circ}C$ for 120 hours, and the chemical compositions of amino acids and vitamins were determinated in every 24 hours during germination. The results obtained are summarized as follows: Before germination, rapeseed contained 5.4g/16g N of glutamic acid and high percentage of the other amino acids in order of Asp>Leu>His>Pro>Arg>Lys>Gly>Ser>Ala>Val. The amino acids were gradually decreased until 96 hours during germination had tendency to show a slight increase in 120 hours. Vitamin B$_1$, B$_2$and C contents in rapeseed before germination were found to be 0.11, 0.21 and 3.72mg% respectively, and the vitamin E was 423ug/g. The vitamin C greatly increased in 72 hours during germination, while the vitamin B group was drastically decreased in 72 hours. The results obtained by this method clearly demonstrate that germination process is very effective to the removal of toxicants in rapeseed.

The purpose of this research was to study food behaviors and nutrient intakes according to body mass index(BMI) and body image recognition in 211 female university students in Incheon. The majority of the surveyed subjects were in the normal range for BMI. Most of these female university students preferred a thin body type and were not satisfied with their body shapes. Most also controlled their body weight for appearance by exercising and limiting food intake. The obese group often ate processed foods(p<0.01) and ate out(p<0.05). The underweight group and normal-weight group took vitamins and supplements more frequently(p<0.001). Those students who recognized their body image as a 'fat shape' had good appetites(p<0.05) and those who recognized themselves as 'normal shape' considered food formulations ate every meal (p<0.05) and consumed vitamins and other supplements frequently(p<0.01). The mean calorie intake of all students was about 80% of the recommend amount, so there was a risk of lack of various nutrients. The 'fat' students by body image recognition had lower calorie intakes in order to reduce body weight. In all the groups, there was a lack of vitamins $B_1$ and $B_2$, as well as the minerals Ca and Fe. Therefore, education on correct body image recognition and training on proper weight control are deemed necessary. In addition, education and counseling on nutrition that are tailored to individual status are needed.

Seakso 5, a maize hybrid, was applied for variety in 2021 by Gangwon Agricultural Research and Extension Services in Korea. This variety was bred to produce a purple extract of com husk. It shows purple color in the husk and cob and contains abundant anthocyanins. In this study, to obtain basic data on purple com 'Seakso 5' husk extract (PCHE), a husk extract was prepared and the contents of vitamins, amino acids and fatty acids were analyzed. The Seakso 5 husks were extracted with 30% alcohol and concentrated, after adding dextrin to the concentrate, it was spray-dried to prepare an extract. The PCHE were analyzed for vitamins, amino acids, and fatty acids by referring to the Food Code. As a result, three types of vitamins were detected, and their contents were vitamin B₁ 0.14 mg/100g, vitamin B₂ 2.30 mg/100g, and vitamin C 11.32 mg/100g. A total of 15 amino acids were detected in the PCHE, including aspartic acid and glutamic acid, and the content of aspartic acid was the highest at 3.02 mg/g. Simultaneous analysis of fatty acids Among 37 types, saturated fatty acids were palmitic acid (C16:0), stearic acid (C18:0), monounsaturated fatty acids were oleic acid (C18:1(n-9)), polyunsaturated fatty acids were linoleic acid(C18:2(n-6)c) and a-Linolenic Acid (C18:3(n-3)) were detected. Among the detected fatty acids, the content of palmitic acid was the highest at 40.75 mg/100g. In the future, These analysis results will be used as reference data for temporary food ingredient applications by the Ministry of Food and Drug Safety.

The present study was designed to evaluate the protective effects of dietary vitamin A or E. and of combination of vitamins A and E on peroxidative deterioration of heart in adriamycin-treated rats. Male Sprague-Dawley rats were assigned to 5 groups according to the dietary supplementation of vitamin A or E Except control rats a dose of 2mg ADR/kg of B. W was injected to these animals intraperitoneally on the same day every week. Adriamycin treatment significantly decreased the weight gain of experimental rats compared with that of control rats, But this decrement was not modified by dietary supplementation of vitamin A or E. Lipid peroxide values of plasma were elevated by ADR treatment. The combined use of ADR and dietary vitamin A or E significantly reduced these values, The interaction between vitamins A and E seemed to be present in the lipid peroxide value of plasma. Catalase and superoxide dismutase(SOD) activities in rat heart were decrased by ADR treatment but glutathione peroxidase(GSH-Px) activity was elevated. Dietary supplmen-tation of vitamin A or E enhanced the heart catalase and SOD activities. except only vitamin A-supplemented group. GSH-Px activity of rat heart tended to be decreased by dietary supple-mentation of vitamin A or E. With ADR treatment polyunsaturated fatty acids such as archido-nic acid(20:4) and docosahexaenoic acid(22:6) were decreased in rat heart. However dietary supplementation of vitamins A and E reduced this decrease. The retinol and tocopherol contents of rat plasma were decreased by ADR treatment. Dietary vitamin A or E influence vitamin A or E content of plasma. The interaction between dietary vitamins A and E was observed in vitamin A or E level of rat plasma.
