This study was attempted to analyze nutritional composition and nutritional balance of domestic and affiliated company of foreign group weaning food. The results were as follows: The proximate compositions were 61%∼70% carbohydrate, 14%∼16% protein, 2.5%∼3.2% ash and 8%∼15% lipid. Leucine content was the highest among all essential amino acids in all test weaning foods. The P/S and linoleic acid / linolenic acid ratio of domestic weaning foods were higher than those of affiliated company of foreign group weaning food. The peroxide values of H, M, S and N product were 13.9 meq/kg oil, 1.1 meq/kg oil, 5.4 meq/kg oil and 14.8 meq/kg oil, respectively.

The aim of the present study was to examine the relationship of maternal factors such as knowledge, attitude and practice of weaning with infant feeding. The subjects were 103 mothers visiting a public health center in Gumi, Kyungbook who filled out self-administered Questionnaires. First of all, about $90\%$ of the participants recognized the importance of complementary foods and proper weaning practices. The response for the recognition of the importance of infant weaning process showed a significant difference by education levels. Concerning an appropriate time for the introduction of weaning foods, $53\%$ of mothers had commenced weaning at age $4\~6$ months, while $38\%$ had done so at age $6\~8$ months. Approximately $76\%$ of mothers fed their babies without the knowledge of age-related weaning method and type of weaning foods. There were no statistical differences in maternal weaning knowledges between levels of education and house income. Mothers with higher levels of education and family income tended to show high perception scores regarding possibility of food allergies caused by baby foods. A demand for reliable sources and education related to nutritious weaning foods and weaning practices were strong in the group with higher education. Knowledge of weaning method and baby foods were obtained by 59 of the 103 mothers from mass media, 35 from friends caring babies, and 9 obtained advice from health professionals or family. Advice from the heath professionals was not the main influence on their decision to introduce weaning foods. Although commercial baby foods are the most commonly used as first weaning foods, those with higher education groups considered commercial baby food are not nutritionally better than home-maid foods. The current findings suggest to us that to improve weaning process, mothers should be educated on the selection and preparation of nutritious, balanced weaning foods and on good weaning practices. It is advised that supportive health professionals from community public health centers should lead the education of infant feeding practices based on maternal characteristics and on basic food and nutritional knowledge.

Timing of weaning is later in Korean rural and lower urban classes compared with middle and upper classes. Weaning after the international standard of six months of age has adverse effects on the growth rate of children. This occurs because supplementary foods are not provided for the child during the weaning period; rather, the infant goes directly from nursing(or bottle feeding) to the cereals and solid foods of the adult diet. Consequently, all nutrient and calorie intake, with the exception of thiamin, in Korean rural children had not yet attained the Recommended Dietary Allowance (RDA). This situation bas created an urgent need for easy to prepare, low priced. highly nutritious supplementary foods. The research team of Yonsei University developed 3 formulas prepared from rice, soybeans, sesame, dry skim milk and fish which are all plentiful and inexpensive items in Korea. A proximate analysis and amino acid determination were performed on three formula. These formulas were prepared and used as exprimental diet for an animal assay. In the animal assay, growth rate, PER evaluated and biochemical analyses were also carried out. A safety storage assay and the cost evaluation were also conducted.

Purpose: This study was carried out to investigate the awareness of the weaning of food using questionnaires, and the relationship with the weight gain in young infants. Methods: From September 2005 to December 2005, we performed a survey on 141 guardians of young infants aged from 6 to 18 months, who visited the pediatric out-patient department at Dongguk University Medical Center. We calculated the total score for each responder from ten questions on the weaning of food and assessed the body weight percentile of each of the young infants. Results: The most commonly reported information source for weaning food was 'the friends around' by 62 respondents (44.0%); 54 (38.3%) responded that the definition of weaning food was the preparatory step before starting a solid diet. Most used a spoon (90.8%) to feed when weaning food with a thin gruel of rice (78.7%). The time for weaning of food was before breast or infant formula feeding (55.3%). Addition of cow's milk was around 12 months (77.3%). The mean score was 6.21; however this did not show a statistically significant correlation with weight gain in young infants. Conclusion: The overall awareness of weaning of food has improved; however, information from doctors has decreased. Although the relationship between the awareness of weaning of food and the growth of young infants was not statistically significant, further studies on weaning of food, with larger and controlled sample sizes may provide important information.

The recognition that omega-3 polyunsaturated fatty acids (n-3 PUFA) possess potent anti-inflammatory properties in human models has prompted studies investigating their efficacy for animal growth and immunity. This study examined the effect of feeding an n-3 PUFA-enriched diet on growth and immune response of weanling piglets. Newly weaned pigs (averaging $27{\pm}2$ days of age and $8.1{\pm}0.7kg$ of body weight) were assigned randomly to receive a control (3% vegetable oil, n = 20) or n-3 PUFA-supplemented (3% marine n-3 PUFA, n = 20) diet for 28 day after weaning. Female pigs consuming the n-3 PUFA-enriched diet were lighter at week 4 post-weaning than those fed the vegetable oil supplement. Weanling pigs gained more weight, consumed more feed and had better growth to feed ratios between days 14 and 28 than between days 0 and 14 post-weaning. Plasma insulin-like growth factor I (IGF-I) decreased between days 0 ($87.2{\pm}17.0ng/mL$) and 14 ($68.3{\pm}21.1ng/mL$) after weaning and then increased again by day 28 ($155.2{\pm}20.9ng/mL$). In piglets consuming the vegetable oil-enriched diet, plasma tumor necrosis factor alpha (TNF-${\alpha}$) increased from $37.6{\pm}14.5$ to $102.9{\pm}16.6pg/mL$ between days 0 and 14 post-weaning and remained high through day 28 ($99.0{\pm}17.2pg/mL$). The TNF-${\alpha}$ increase detected in the piglets fed vegetable oil was not observed in the piglets fed n-3 PUFA. Results indicate that weaning induces considerable immune stress in piglets and that this stress can be mitigated by dietary supplementation of n-3 PUFA.

This study was undertaken to classify Enterobacter sakazakii isolates from 13 powdered infant formula products, 25 powdered weaning diet products, and 33 weaning diet ingredients on polymerse chain reaction (PCR) methods. The numbers of the isolates from 1 powdered infant formula product, 7 powdered weaning diet products, and 6 weaning diet ingredients were 1, 14, and 8, respectively. The contaminated ingredients were 1 rice powder, 2 millet powders, 2 vegetable powders, and 1 fruit and vegetable premix. PCR with the primer of repetitive extragenic palindromic element (REP-PCR) and random amplification of polymorphic DNA(RAPD) were effective in discriminating among the isolates, but tRNA-PCR and PCR with the primer of l6S-23S internal transcribed spacer (ITS-PCR) were not. Some of E. sakazakii isolates from vegetable powders, fruit and vegetable premix, and millets powders were classified into the clonal groups based on the DNA patterns in the REP-PCR and RAPD analysis. A close genetic relationship among the isolates from some of the powdered weaning diet products and the rice powder was also detected in the cluster analysis based on the DNA patterns in RAPD.

The purpose of this study was evaluate the perception on the relationship between feeding and atopic dermatitis of infants. The results are summarized as follows:. The feeding method of atopic dermatitis infant was composed of breast feeding 26.9%, bottle feeding 50.9%, and mixed feeding 22.2%. 95.3% of the subjects recognized mother's meal during breast feeding were transmitted to infant, but 30.8% of breast feeding restricted their foods. Weaning food was recognized as a nutritional supplement primarily. 61.5% of the subjects perceived the relation between food and atopic dermatitis and 58.8% of the subject perceived atopic dermatitis infants will be cured by growing. 39.9% of the subjects answered that special food developed and made worse atopic dermatitis in their infants. Egg, mackerel, milk, pork, chicken scored high as doubtful food related with atopic dermatitis. It is necessary to find out the food that develop atopic dermatitis symtoms and make guidelines for diet therapy for the infants with atopic dermatitis.

1) A process was described for the preparation of drum-dried weaning food containing about 20% protein and based on a blend of sweet potato, full-fat soy flour, minerals, vitamins and methionine. 2) The protein efficiency ratio of this product was 2.63 as compared to 3.30 for the blend containing corn starch in place of sweet potato. This is attributed to the partial destruction of available lysine in the presence of sweet potato during the drum-drying process. 3) Overall nutritive value of the weaning food was comparable to milk food and control food based on corn starch and soy flour in terms of feed efficiency, body composition and protein retention.

Objective: To evaluate the use of nurse sows and post-weaning nutrition strategies for low wean weight (WW) pigs on lifetime growth and efficiency. Methods: Animals (n = 270) were assigned to one of five treatments at 28 d. Low WW pigs (<6 kg) were either weaned and offered a special dietary regime recommended for low WW pigs (WEAN) or placed on a nurse sow (NURSE) and weaned at 49 d. Normal WW pigs (9 kg) (NORM) were also weaned at 28 d. After weaning, NORM and NURSE pigs were offered either a 'high' (4 kg/pig of starter 1 diet followed by 8 kg/pig of starter 2 diet) or 'low' (8 kg/pig of starter 2 diet) starter diet allowance in a 2×2 factorial arrangement. A typical grower diet was then offered, followed by a typical finisher diet until 147 d of age. Results: NORM pigs where heavier throughout their life compared to NURSE pigs (91.4 kg vs 76.2 kg at 147 d; p<0.001). WEAN pigs were heavier at 70 d compared to NURSE pigs (23.9 kg vs 21.0 kg; p<0.001), but there was no significant difference at 147 d between NURSE and WEAN treatments. NURSE pigs had reduced feed intake throughout the finishing period (1.6 kg/d; p<0.001) compared to WEAN (2.0 kg/d) and NORM (1.9 kg/d) pigs. Feed conversion ratio (FCR) of NURSE (2.20) was lower than NORM and WEAN during the finishing period (2.40 and 2.79, respectively). Conclusion: Extended (up to 49 d) nursing for low WW pigs resulted in improved FCR during the finishing period, but no overall improvement in growth rate compared to low WW pigs weaned at 28 d and offered a specialised starter regime. Normal WW pigs where significantly heavier than low WW pigs throughout the study.

The purpose of this study is to examine the effects of pre-school children's past lactation types and food habits on dental health status. This study was carried out by analyzing the information obtained from oral inspection of 163 preschool children and questionnaires answered by their mothers. The results are as follows: 1. 80.4% of the preschool children have decayed and filled teeth. 2. The older they are, the more decayed and filled teeth they have 3. The earlier they started to have weaning foods, the more decayed and filled teeth they have. Preschool children who started weaning foods after 12 months of their birth have significantly more decayed and filled teeth. 4. Preschool children who had weaning foods by using milk-bottles have significantly more decayed and filled teeth than others. 5. Preschool children who had weaning foods regularly have significantly less decayed and filled teeth. 6. Preschool children who have frequently skipped breakfast have the least decayed and filled teeth. 7. Preschool children who would like to have sweet things have significantly more decayed and filled teeth than others.
