It makes a through study on the medical treatment mechanism and efficacy of colostral milk, the results as fllows. 1. Colostral milk is some special things for baby newborn, and the other men and women of course. It is low in fat, and high in carbohydrates, protein, and antibodies to help keep your body healthy. Colostral milk is easy to digest, and it is low in volume, but high in concentrated nutrition for the newborn and men and women. 2. Colostral milk provides some of living cells which will defend babies against many harmful agents. The immune factors is much higher in colostral milk than in nature milk. Colostral milk works as a vaccine. It contains some quantities of an antibody called secretory immunoglobulin A Which is a important substance to the baby and men, 3. Colostral milk has a role to play in the baby's gastrointestinal tract. A newborn's intestines are permeable. The colostral milk makes the gastrointestinal tract in general. In addition, colostral milk contains a lot of leukocytes.

Objective: Because lactation periods in dairy cows lengthen with increasing total milk production, it is important to predict individual productivities after 305 days in milk (DIM) to determine the optimal lactation period. We therefore examined whether the random regression (RR) coefficient from 306 to 450 DIM (M2) can be predicted from those during the first 305 DIM (M1) by using a RR model. Methods: We analyzed test-day milk records from 85,690 Holstein cows in their first lactations and 131,727 cows in their later (second to fifth) lactations. Data in M1 and M2 were analyzed separately by using different single-trait RR animal models. We then performed a multiple regression analysis of the RR coefficients of M2 on those of M1 during the first and later lactations. Results: The first-order Legendre polynomials were practical covariates of RR for the milk yields of M2. All RR coefficients for the additive genetic (AG) effect and the intercept for the permanent environmental (PE) effect of M2 had moderate to strong correlations with the intercept for the AG effect of M1. The coefficients of determination for multiple regression of the combined intercepts for the AG and PE effects of M2 on the coefficients for the AG effect of M1 were moderate to high. The daily milk yields of M2 predicted by using the RR coefficients for the AG effect of M1 were highly correlated with those obtained by using the coefficients of M2. Conclusion: Milk production after 305 DIM can be predicted by using the RR coefficient estimates of the AG effect during the first 305 DIM.

Twenty-five fungal strains producing an extracellular soybean milk clotting enzyme were isolated from 146 soil samples, and identified as 11 species belonging to six genera of Aspergillus oryzae (5 strains), Aspergillus flavus (2 strains), Aspergillus parasiticus (1 strain), Aspergillus tamarii (2 strains), Aspergillus niger (4 strains), Aspergillus fumigatus (2 strains), Mucor hiemalis (2 strains), Wallemia sebi (4 strains), Scopulariopsis condida (1 strain), Fusarium redolens(1 strain) and Verticillum lecanii (1 strain). Among them, Aspergillus oryzae 020 and Aspergillus tamarii 287 showed relatively high soybean milk clotting activity. The coagulabilities of the enzyme from representative strains of those species decreased as the pH of soybean milk increased from 6.0 to 7.0 The optimum temperature for soybean milk clotting enzymes of those strains were 65$^{\circ}C$.

The objective of the study was to compare ranking of Sahiwal bulls selected on the basis of highest lactation milk yield of their dams with their estimated breeding values (EBVs) using an animal model. Data on 23,761 lactation milk yield records of 5,936 cows from five main Livestock Experiment Stations in Punjab province of Pakistan (1964-2004) were used for the study. At present the young A.I bulls are required to be from A-category bull-dams. Dams were categorized as A, B, C and D if they had highest lactation milk yield of ${\geq}$2,700, 2,250-2,699, 1,800-2,249 and <1,800 litres, respectively. The EBVs for lactation milk yield were estimated for all the animals using an individual animal model having fixed effect of herd-year and season of calving and random effect of animal. Fixed effect of parity and random effect of permanent environment were incorporated when multiple lactation were used. There were 396 young bulls used for semen collection and A.I during 1973-2004. However, progeny with lactation yields recorded, were available only for 91 bulls and dams could be traced for only 63 bulls. Overall lactation milk yield averaged 1,440.8 kg. Milk yield was 10% heritable with repeatability of 39%. Ranking bulls on highest lactation milk yield of their dams, the in-vogue criteria of selecting bulls, had a rank correlation of 0.167 (p<0.190) with ranking based on EBVs from animal model analysis. Bulls' EBVs for all lactations had rank correlation of 0.716 (p<0.001) with EBVs based on first lactation milk yield and 0.766 (p<0.001) with average EBVs of dam and sire (pedigree index). Ranking of bulls on highest lactation yield of their dams has no association with their ranking based on animal model evaluation. Young Sahiwal bulls should be selected on the basis of pedigree index instead of highest lactation yield of dams. This can help improve the genetic potential of the breed accruing to conservation and development efforts.

The amino acid composition of human and cow's milk represents a standard of reference in infantnutrition. The amino acid compositions determined by automatic amino acid analyzer, Yanagimote Model LC-5. Protein in the human and cow's milk were found to be hydrolyzed to yield free amino acids. Qualitative data for free amino acids in the milk are as follows: 1) Amounts of acidic amino acids such as glutamic and aspartic acid in cow's milk were obserbed to be about 2 times compared with human milk and it is considered that the abundance in these amino acids may contribute significantly to the specific flavor of cow's milk. 2) It is much interesting that in the human milk the contents of sulfur-containing amino acids were high comparatively better than cow's milk; cystine was found to be 3 times ana methionine, 2 times. 3) In the human milk a high content of some essential amino acids such as threonine, isoleucine and leucine was demonstrated and a specific flavor sweet amino acids. 4) Large amounts of basic amino acid such as histidine was found to occur in human milk and arginine in cow's milk.

Purpose: The cow's milk-related-symptom-score (CoMiSS) tool was developed as an awareness tool for the assessment of cow's milk-related symptoms in infants or children. Fecal calprotectin (FC) is a noninvasive biomarker of gut inflammation that can be measured in serum and stool. This study aimed to investigate the relationship between FC levels and CoMiSS scores in infants with cow's milk protein allergy. Methods: Infants (aged 6-12 months) who were allergic to cow's milk protein were enrolled prospectively. Following completion of the CoMiSS scoring, the infants were divided into group 1 (positive CoMiSS scores ≥12) and group 2 (negative CoMiSS scores <12). FC was measured using immunoassay. Results: Of the 120 infants enrolled in this study, 60 (50.0%) had positive CoMiSS scores (group 1), while 60 (50.0%) had negative scores (group 2). The mean FC level was higher in the infants in group 1 than those in group 2 (2,934.57 ㎍/g vs. 955.13 ㎍/g; p<0.001). In addition, there was a positive correlation between FC and CoMiSS scores (R=0.168, p<0.0001). A FC level of 1,700 ㎍/g provided a sensitivity of 98.3%, specificity of 93.3%, and accuracy of 95.8% for the diagnosis of cow's milk protein allergy (CMPA). Conclusion: FC measurement may have a role in the assessing infants with CMPA.

The aim of the present study was to determine the effect of dietary cultured wild ginseng root (CWGR) supplementation on goat milk composition and ginsenoside profiles. Sixteen Saanen dairy goats were allocated to two balanced groups based on lactation period, body weight ($38.6{\pm}3.2kg$), and dairy milk yield ($2.85{\pm}1.2kg$), and were kept in separate pens. Goats were fed a total mixed ration (TMR) feed (2.3 kg/d, dry matter basis) and 1.5 g of CWGR powder was supplemented in the experimental diet. The total feeding period was 3 weeks, and milk and blood samples were collected on the last three days of the experimental period. There was no effect of CWGR on daily milk yield and milk composition (fat, protein, lactose, and solid-not-fat). However, the CWGR-treatment group had significantly higher plasma IgG and protein contents than the control group (P < 0.05). Significant amounts of ginsenosides were observed in the milk of the CWGR-treatment group, whereas ginsenosides were not detected in the milk of the control group. In conclusion, dietary CWGR was a useful regimen to produce functional goat milk enriched in ginsenosides.

This study was performed to investigate the relationship between milk and milk product consumption and dietary nutrient intake among Korean adolescents. Questionnaire survey and 3-day diet survey using the food record method were completed by a total of 664 subjects. Subjects were divided into three groups, Q1 (low group), Q2 (middle group), and Q3 (high group), according to dairy equivalent of calcium. Dairy equivalent of calcium was determined by the amount of calcium eaten from milk and milk products by individual subjects. As a result, the ratio of school milk service was higher in Q3 (P<0.001). The most frequent answer about the reason for consuming milk and milk products was 'to be taller' followed by 'good taste' and 'health promotion'. Preference for all types of milk such as white-, enriched-, and flavored-milk was higher in Q3 followed by Q2>Q1 (P<0.05). Ratio of mean daily dietary nutrient intakes of dietary fiber, vitamin C, folate, and calcium to RNI was lower than 2/3 for all of the groups. These mean daily dietary nutrient intakes were significantly higher in Q3 (P<0.05), and in particular, mean daily dietary calcium intake, which was the lowest nutrient consumed by Korean adolescents, was also the highest in Q3 followed by Q2>Q1 (P<0.05). The above results suggest that the school milk program is very helpful in encouraging adolescents to consume milk and milk products and consequently ensure their optimal nutrition. Therefore, we should try to encourage adolescents to participate in the school milk program more actively through nutritional education and government policy.

For a survey of the occurrence of aflatoxin M$_{1}$ (AFM$_{1}$) in domestic cow's milk, we developed an enzyme-linked immunosorbent assay (ELISA) system, and quantitated the toxin in cow's milk. In order to produce specific antibodies AFM, conjugated to bovine serum albumin (AFM$_{1}$-BSA) and Freund's adjuvant were immunized subcutaneously to rabbits. By use of the antiserum showing the highest titer and AFB$_{1}$-HRP conjugate, we established a competitive direct ELISA (cdELISA) for AFM$_{1}$, whose detection limit was 0.003 ppb. The cross-reactivities of the antiserum against aflatoxin M$_{1}$ M$_{2}$, B$_{1}$, B$_{2}$, G$_{1}$, G$_{2}$, B$_{2a}$, and G$_{2a}$, were 100, 29.9, 25.0, 2.7, 13.0, 0.65, 0, and 0%, respectively. When the cdELISA was applied to the cow's milk spiked with AFM$_{1}$ and followed by cleanup with C$_{18}$ cartridge, the mean recovery of the assay was 104% (mean of CV, 6.4%) in the final concentration of 0.01-1 ppb (10-1, 000 ppt). When cow's milk samples gathered from markets and farms were assayed by the cdELISA, the mean concentration and SD of AFM$_{1}$ was 80.4 $\pm$ 55.0 ppt (n=64; range, 5.6-280 ppt).
