The objective of this study was to evaluate the effect of dietary fat inclusion on nutrient intake, body weight, milk production, return to estrus, pregnancy and lambing of winter-lambing, postpartum Awassi ewes. Thirty multiparous, winter-lambing Awassi ewes (body weight=51${\pm}$7.0 kg) were randomly assigned to three dietary treatments (n=10) for 62 days using a completely randomized design. Experimental diets were isonitrogenous, and were formulated to contain 0 (CON), 2.5 (MF), and 5% (HF) added fat, and 33% of the dietary crude protein (CP) as undegradable intake protein (UIP). On day 26 postpartum (day 0=parturition), ewes and their lambs were housed in individual pens for 28 days. Feed offered and refused was recorded daily. At the end of this period, ewes and their lambs within each treatment were combined into one group and fed their respective diet ad libitum. One fertile Awassi ram fitted with a marking harness was allowed with each group for 34 days. No significant (p>0.05) differences in dry matter intake, organic matter intake, and crude protein intake were observed for ewes fed the three experimental diets. No difference was observed in metabolizable energy intake (MEI) for ewes fed the CON and the MF diets (average 8.3 Mcal/d) diet. However, ewes fed the HF diet had greater(p<0.05) MEI compared with the rest of the treatments. Ewe body weights increased throughout the study, unaffected by the experimental diets. No significant differences in milk production were found among ewes fed the three experimental diets. No significant differences were observed in pregnancy rate (6/10, 5/10, 6/10 for CON, MF and HF diets, respectively), lambing rate and the number of lambs per ewe among the three treatments. postpartum reproductive performance of well-fed, winter-lambing Awassi ewes.

Purpose: The purpose of this study is to investigate the effect of Boheo-tang (B) and Boheo-tang plus cervi pantotrichum cornu (B+CP) on lactation in postpartum C57BL/6N mice. Methods: Normal saline(control), Band B+CP (8mu l/g$) were administerd p.o. twice a day for 20 days. Lactating mammary gland tissues were examined through light microscope by the way of HE staining and immunohistochemical assay. Milk producing associated gene expression were accessed by RT-PCR. Results: In mammary gland, amount of adipose tissues were decreased in both Band B+CP treated group. And the ductal branches and alveolar tissues increased in both treated group. Immunoreactivity of prolactin receptors was increased both treated group, and immunoreactivity of oxytocin receptors was increased in the B+CP treated group. In both treated group, IGF-l mRNA expression was increased and TGF-$\beta$ mRNA expression was decreased. And PRL mRNA expression was increased in the B+CP treated group. PL-l mRNA expression was decreased in the B treated group but increased in the B+CP treated group. Conclusion: This study shows that treatment of Boheo-tang and Boheo-tang plus cervi pantotrichum cornu can improve postpartum lactation in C57BL/6N mice.

The goal of this study was to investigate the behavior of sows and their piglets reared using the non-all-in all-out system and the all-in all-out system during a 3-week lactation period. The 24 Landrace${\times}$Yorkshire sows (range of parity: 2 to 4) and their litters (range of litter size: 8 to 13 piglets) for each treatment (8 sows/replication) were used in this experiment. The sows were housed in farrowing crates ($0.6{\times}2.1m$) located in pens ($2.4{\times}1.8m$) with totally perforated metal flooring. The crates were kept in an experimental room that was thermostatically controlled to approximately $23^{\circ}C$. A 250-W infrared heat lamp was turned on above the creep area during lactation. The sows and piglets were conventionally managed. The animals were recorded during a 24-h period at 1, 4, 7, 14 and 21 days postpartum. The videotapes were scanned every minute to obtain an instantaneous behavioral sample. In the behaviors of sows, lateral recumbency decreased and ventral recumbency increased from 1 day postpartum to 21 days postpartum. In comparison to the AIAOS, sows in the NAIAOS spent much less time on lateral recumbency (p<0.01), whereas they spent much more time on ventral recumbency and sitting at 4 days postpartum (p<0.05 and p<0.05). In the behaviors of piglets, lying increased and unsuccessful suckling decreased until 21 days postpartum. Compared to the AIAOS at 4 days postpartum, piglets in the NAIAOS spent less time lying (p<0.01), whereas they spent much more time walking and unsuccessful suckling (p<0.01 and p<0.05). These results suggest that the all-in all-out system may be preferable to the non-all-in all-out system for promoting welfare.

Objective : The aim of this study is to investigate rota virus infection of neonates In the Postpartum care center. Methods : This clinical study was carried out with the 205 neonates who admitted to the Postpartum Care Center of ${\bigcirc}{\bigcirc}$ Oriental Medicine Hospital, from July, 2004 to July, 2005. Stools were examined daily with Rotazyme ELISA tests(Bio Line Rota Virus, SD Standard Diagnostics, INC.) for 3 days from the day of admission. Supplementary test was examined when change was found in stools. Results : Among 205 newborn babies, 58 cases turned out to be positive. The positive rate of rota virus was not significantly related to sex, birth weight, gestation age. But, it was significantly related to delivery method and it was higher in caesarean section group. The manifestation rates of symptoms were 51.7% in Rotazyme positive neonates. In the Rotazyme positive 58 cases, 30 cases(51.7%) had diarrhea, 8 cases had fever(13.8%), 1 case(1.7%) had vomiting. The positive rate of rota virus was higher during from october to march. There were 190 cases(92.2%) of mixed feeding and 15 cases(7.8%) of artificial feeding. There was significance between breast feeding and the positive rate of rota virus. There was no significance between hospital of birth and the rate of positive rotazyme test. Conclusions : A further study of neonates in postpartum care center is necessary as preference of postpartum care center was increased. And the oriental medicine treatment of rota virus IS expected to be effective, so a further study is necessary.

The aim of this study is to examine size-based concentration and genera of airborne fungi distributed in public facilities such as hospital, kindergarten, day-care center and postpartum nurse center and to provide fundamental data in order to prevent respiratory diseases caused by exposure to airborne fungi. Culturable total and respirable concentrations of airborne fungi averaged to $382\;cfu/m^3\;and\;292\;cfu/m^3$ in hospital, $536\;cfu/m^3\;and\;347\;cfu/m^3$ in kindergarten, $334\;cfu/m^3\;and\;266\;cfu/m^3$ in day-care center, and $371\;cfu/m^3\;and\;289\;cfu/m^3$ in postpartum nurse center, respectively. The ratio of respirable to total concentration of airborne fungi in the investigated public facilities was ranged from $55\%\;to\;70\%$ but there was no significant difference among them (p>0.05). The mean I/O ratio of culturable total and respirable concentrations were 0.56 and 0.64 in hospital, 0.72 and 0.91 in kindergarten, 0.33 and 0.45 in day-care center, and 0.63 and 0.73 in postpartum nurse center, respectively. Indoor concentration of airborne fungi did not correlated significantly with indoor temperature and relative humidity (p>0.05) but had a significant positive correlation with $CO_2$ concentration (p<0.01) and surrounding condition (p<0.05). Penicillium spp., Cladosporium spp., and Aspergillus spp. were estimated to over $95\%$ of total airborne fungi identified in the investigated public facilities.

The present study was designed to determine the effect of barn or cycle of grazing on changes of biochemical metabolites in prepartum and changes of milk composition in postpartum of dairy cows. For this purpose, a total of sixteen 25 months old Holstein primiparous dairy cows were allocated in two groups (n=8) with an average body weight of 571.61 ± 35.30 kg (Barn) and 578.10 ± 39.20 kg (Grazing). The study was conducted from June 2018 to October 2018. Results revealed that barn raised dairy cows had a higher increase in their serum albumin and calcium level on day 14 prepartum. However, the level of palmitic acid, saturated fatty acid increased significantly, and the level of fat, oleic acid, γ-linoleic acid, arachidonic acid and unsaturated fatty acids decreased significantly in barn raised dairy cow's milk on day 14 postpartum. There were no significant differences observed with respect to all other biochemical metabolites, fatty acids and minerals between barn raised and cycle grazing dairy cows during prepartum and postpartum. Our study results could serve to a better understanding of barn raised cow with respect to changes of biochemical metabolites in prepartum and changes of milk composition, fatty acids and minerals content in grazing dairy cows in postpartum for estimating their physiological status.
