A prolonged farrowing interval is common on small farms in Nepal and may be attributable to the absence of boar contact at the time of weaning. To examine whether synthetic boar pheromone spray might be of value to aid the stimulation and detection of estrus, 30 village farms, each with a single sow, were recruited into a field study. All sows entered the study on final weaning from their first lactation at 56 days post partum. For 13 treatment sows, a boar pheromone spray (SOA, Intervet, Boxmeer, The Netherlands) was applied each day after weaning whilst 17 other sows did not receive any stimulus (negative control). When estrous was detected by the farmer, sows were taken to the nearest boar for service. There was a significantly shorter weaning to re-mating interval for treatment sows (42.9 V 82.2 day, p<0.05), with a significantly higher proportion of treatment sows rebred by day 60 after weaning (p=0.024, Fishers Test). It is concluded that use of boar pheromones can improve reproductive efficiency of sows kept under Nepalese village conditions.

Doctors who treat pregnant women ore usually cautious in writing their prescription for the drugs. The problem of which psychotropic medications ore sale during pregnancy seems to remain unsolved for many years. Although the rate of absorption is reduced due to a reduced rate of gastric emptying, the extent of absorption of drug is generally unchanged during pregnancy. Plasma volume and total body water increase during pregnancy. There is suggestion that drug metabolizing activity may be increased in pregnancy. Since the pregnancy increase the glomerular filtration rate significantly, drugs mainly eliminated by renal excretion will be cleared more quickly. Factors contributing to the potential teratogenecity of a drug include the type of compound, dose and duration of use, developmental stage of fetus at the time of exposure, and the effect of the drug on fetal pharmacokinetics. All major classes of psychotropic agents should be assumed to diffuse readily across the placenta to the fetus and to be present in some quantity in the breast milk. To decide when and how to start the drug treatment depends on an assessment of the risks related both with and without drug treatment of psychiatric disorders.

Nitrogen(N) concentration of preterm(PT) and term (T) milk in various fractions, such as total, protein, nonprotein, whey protein and casein were determined at 2-5 days, 1, 2, 4 and 6 weeks of postpartum. The purpose of this study was to investigate the nitrogen concentration of human milk from mothers delivering at preterm and term, and the propriety of preterm milk for premature infants. The concentration of total N, nonprotein N, protein N, whey protein N and casein N in preterm milk was decreased significantly with time postpartum. Total N was 374mg/이 at colostrum, 232mg/dl at mature milk. Whey protein N was decreased from 42mg/dl at 2-5 days to 32mg/dl at 4-6 weeks. Protein N was 332mg/dl at colostrum, 202mg/dl at mature milk. The proportion of whey protein N and casein N were 39:61 at colostrum, 28:72 at mature milk. No difference were found between T and PT milk for total nitrogen excepted 2 weeks. In this report we show that nitrogen concentration except casetpt casein N is smaller in milk from mothers giving birth prematurely than in milk from mothers giving birth at term, over the first two weeks of lactationl But protein N was higher in preterm milk than term milk, whey protein nitrogen was lower. By comparing predicted nitrogen intakes to estimated requirements of preterm infants fed 150 to 200ml/kg/day of their own mother's milk, we predict that the quantities of protein provided would be adequate to meet the requirements of the prematured infants during the early weeks of life.

This study reviewed on the occupational health status of female workers in China, where the half of female population are workers in occupational settings and realizes the importance of occupational health among them, to establish the occupational health management system in Korea as Korean female workers have been increasing for the last few decades. Results of the study were as follows. 1. The proportion of female workers in total workers have increased from 7.5% in 1949 up to 37.6% in 1990. As for the distribution of female workers by industry, manufacturing part has the highest proportion of female workers in total and out of total female workers, the rank was health social welfare (53.2%), community personal service(45.4%) and agriculture forestry fishing(44.1%). 2. The system of occupational health management for female workers was related to superior organization well by administrative district & work place and professionals were distributed to one per ten thousand persons or more, depending on each region's conditions. 3. The regulations of occupational health management for female workers are defined in a variety of fields. Considering the physiological characteristics of female workers, government has tried to minimize the loss due to menstruation, pregnancy, delivery and lactation and has let them have vacations, guaranteeing the health facilities at the same time. Also government has defined the scope of prohibited work to protect legal right of them.

Purpose: This study was done to identify the effects of self-breast pumping on breastfeeding rates and, the degree of breast milk fullness among primiparous women giving birth by cesarean section. Methods: The study design was a non-synchronized posttest control group experiment with repeated measures. The participants were 60 women, 31 in the experimental group who used a manual pump 5 times a day after exclusive breastfeeding and 29 in the control group who breastfed exclusively with no other interventions. Results: While self-breast pumping did not improve breastfeeding rates or the degree of breast milk fullness at any of the time points studied, breastfeeding rates continued to remain high till 12 weeks postpartum in both groups. Conclusion: Although some modifications in research methods will be required to identify the effects of breast pumping and exclusive breastfeeding, both these approaches can be used as interventions to improve breastfeeding rates and breast milk quantity.

Recently, for successful lactation, many breastfeeding mothers seek various products, including herbal medicine, dietary supplements, and prescribed medicines, to improve milk production. As demand for galactogogues grows, it is highly possible that pharmaceutical galactogogues may be adulterated with illegal products to maximize their efficacy. For continuous control and supervision of illegal products, we developed and validated a simple and sensitive LC-MS/MS method capable of simultaneously determining five galactogogues. Chromatographic separation was conducted using an Agilent Poroshell $120SB-C_{18}$ column with a mobile phase consisting of 20 mM ammonium formate (pH 5.4) and 100 % acetonitrile. The total run time was 13 min per analyte. The proposed method was performed according to the guidelines of the International Conference of Harmonization and it produced reliable results. This method showed high sensitivity and specificity, with a limit of detection (LOD) and limit of quantitation (LOQ) of 0.01-0.82 ng/mL and 0.02-2.45 ng/mL, respectively, for the solid- and liquid-type samples. Specificity was evaluated by analyzing matrix-blank samples spiked with the target compounds at LOQ levels, which provided a good separation of all peaks without interference. Additionally, the repeatability and intermediate precision were typically <15 %, whereas the recovery was 80-120 % of the values obtained using blank samples. Thus, we concluded that this method could be used for the identification and quantification of galactogogues in food or herbal products.

Although the chemical, physical, and nutritional properties of bovine milk have been extensively studied, only a few studies have attempted to characterize milk-synthesizing genes using RNA-seq data. RNA-seq data was collected from 21 Holstein samples, along with group information about milk production ability; milk yield; and protein, fat, and solid contents. Meta-analysis was employed in order to generally characterize genes related to milk production. In addition, we attempted to investigate the relationship between milk related traits, parity, and lactation period. We observed that milk fat is highly correlated with lactation period; this result indicates that this effect should be considered in the model in order to accurately detect milk production related genes. By employing our developed model, 271 genes were significantly (false discovery rate [FDR] adjusted p-value<0.1) detected as milk production related differentially expressed genes. Of these genes, five (albumin, nitric oxide synthase 3, RNA-binding region (RNP1, RRM) containing 3, secreted and transmembrane 1, and serine palmitoyltransferase, small subunit B) were technically validated using quantitative real-time polymerase chain reaction (qRT-PCR) in order to check the accuracy of RNA-seq analysis. Finally, 83 gene ontology biological processes including several blood vessel and mammary gland development related terms, were significantly detected using DAVID gene-set enrichment analysis. From these results, we observed that detected milk production related genes are highly enriched in the circulation system process and mammary gland related biological functions. In addition, we observed that detected genes including caveolin 1, mammary serum amyloid A3.2, lingual antimicrobial peptide, cathelicidin 4 (CATHL4), cathelicidin 6 (CATHL6) have been reported in other species as milk production related gene. For this reason, we concluded that our detected 271 genes would be strong candidates for determining milk production.

The present study was carried out to investigate the behaviour of parturition, nursing and sleep with a total of 40 sows and 420 piglets during 28 days from July 6 to August 3, 1984. The results obtained in this study were as follows: 1. About half number of sows employed were recumbent and lay on their right or left side throughout the process of delivery, but the rest changed their lying sides during the delivery, about 65% of piglets born were presented anteriorly. During nursing 51.3% of sows were recumbent and lay on their left side. 2. The entire farrowing process normally lasted 4 hr. Piglets were expelled at an average rate of one for every 19.3mim. 3. The first suckling attempt was observed at about 24.3min after birth. "Teat order" were established within 32hr after birth. 4. The duration and time of nursing were 35.8 second and 24.6 times/day, respectively, in the first day of piglet life. However, they tended to shorten with the advance of lactation. The intervals between nursings were 58.5 min. in the first day of piglet life, but it tended to lengthen with the advance of lactation. 5. The sows were awake for 31.7%. drowsy for 16.7%, and asleep for 51.6% of the 24hr period a day.

This study was conducted to evaluate the effect of dietary antioxidant and energy density on performance and antioxidative status in transition cows. Forty cows were randomly allocated to 4 dietary treatments in a $2{\times}2$ factorial design. High or low energy density diets (1.43 or 1.28 Mcal $NE_L$/kg DM, respectively) were formulated with or without antioxidant (AOX, a dry granular blend of ethoxyquin and tertiary-butylhydroquinone; 0 or 5 g/cow per d). These diets were fed to cows for 21 days pre-partum. During the post-partum period, all cows were fed the same lactation diets, and AOX treatment followed as for the pre-partum period. Feeding a high energy diet depressed the DMI, milk yield, and 4% fat-corrected milk (FCM) of cows. However, AOX inclusion in the diet improved the milk and 4% FCM yields. There was an interaction of energy density by AOX on milk protein, milk fat and total solids contents. Feeding a high energy diet pre-partum increased plasma glucose and ${\beta}$-hydroxybutyrate, whereas dietary AOX decreased plasma ${\beta}$-hydroxybutyrate value during the transition period. There were also interactions between time and treatment for plasma glutathione peroxidase activity and malondialdehyde content during the study. Cows fed high energy diets pre-partum had higher plasma glutathione peroxidase activity 3 days prior to parturition, compared with those on low energy diets. Inclusion of AOX in diets decreased plasma glutathione peroxidase activity in cows 3 and 10 days pre-partum. Addition of AOX significantly decreased malondialdehyde values at calving. Energy density induced marginal changes in fatty acid composition in the erythrocyte membrane 3 days post-partum, while AOX only significantly increased cis-9, trans-11 conjugated linoleic acid composition. The increase in fluidity of the erythrocyte membrane was only observed in the high energy treatment. It is suggested that a diet containing high energy density pre-partum may negatively affect the anti-oxidative status, DMI and subsequent performance. Addition of AOX may improve the anti-oxidative status and reduce plasma ${\beta}$-hydroxybutyrate, eventually resulting in improved lactation performance; the response to AOX addition was more pronounced on the high energy diet.
