Recently, the number of patients who received Bone Marrow Transplantation(BMT) has been increased dramatically and the diseases for which BMT if efficacious are increasing. Adequate nutritional card for BMT patients is crucial for the success of BMT because nutritional deficiency could provoke deteriorative effects. However, little is known about nutritional status among BMT patients in Korea. This study was conducted to assess oral and parenteral intake of BMT patients and compare the change of nutritional status before and after BMT. Twenty-two BMT patients who were admitted to the Severance hospital from December in 1995 to September in 1997 participated in the study. Total calorie requirements were calculated for each patients individually and nutritional support for each patients consisted of oral and parenteral feeding. To assess oral intake of BMT patients, each patients recorded the amount of food they have eaten from 6 days before BMT to 28 days after BMT. The medical records of each patients were used to assess parenteral intake. To compare the nutritional status before and after BMT, the results of anthropometric and biochemical test from 14 days before BMT to 28 days after BMT were used. At the time of admission, the patients were in allowable nutritional status and their total calorie intake was 93% of total calorie requirement. When the preparative regimen for BMT was started, the patients' oral intake was dramatically decreased below 400kcal/day. Even though their oral intake was increased after BMT, their oral intake at the 4th week after BMT was only 752kcal/d, which is only 35.8% of total calorie requirement. The patients' mean oral intake during BMT period (from 6 days before BMT to 28 days after BMT) was only 439kcal/d. Although Total Parenteral Nutrition(TPN) was added when the preparative regimen was started, the patients' mean total caloric intake during BMT period was 111% of basal energy expenditure and 83% of total calorie requirement. The mean total protein intake was only 58% of total protein requirement. In the comparison of nutritional status between pretransplant phase and posttransplant phase in BMT patients, their body weight and serum albumin level were significantly decreased(p<0.001). These results show inadequacies in nutritional intake among BMT patients, and indicate the need of TPN during BMT period.
The present study was designed to assess whether dietary inorganic and organic selenium (Se) could affect antioxidant enzymes, including superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and glutathione-S-transferase (GST), and the level of malondialdehyde (MDA), a marker of lipid peroxidation, in the intestine, serum, liver, and gastrocnemius muscle of Korean native goats. A total of eighteen Korean native goats was allotted into three dietary groups, consisting of basal diet (CON), or basal diet with either 0.25 ppm inorganic (IOSEL) or 0.25 ppm organic Se (ORSEL), and fed the corresponding diets for 5 wks. Growth performance, including body weight and total gain, and blood biochemical profiles, including GSH-Px, were not significantly different between the three dietary groups. Also, the specific activities of SOD, GSH-Px, and GST, and the level of MDA in the intestinal mucosa and liver from goats were not substantially affected by either inorganic Se or organic Se. However, goats fed the diet containing organic Se showed a significant increase in GSH-Px and GST activities in the gastrocnemius muscle compared with those fed the basal diet. In conclusion, increased muscle GSH-Px and GST activities suggest that dietary organic Se may affect, at least in part, the antioxidant defense system in muscle of Korean native goats under the conditions of our feeding regimen.
Bovine whey protein expression patterns of colostrum are much different from that of milk. Moreover, bovine colostrum is an important source of protective, nutritional and developmental factors for the newborn. However, to our knowledge, no research has been performed to date using a comparative proteomic method on the changes in the bovine whey proteome during the transition from colostrum to milk. This study therefore separated whey protein of days 1, 3, 7 and 21 after calving using two dimension electrophoresis. Differentially expressed proteins at different collection times were identified using high-performance liquid chromatography in tandem with mass spectrometry (LC/MS) and validated by enzyme-linked immunosorbent assay (ELISA) in order to understand the developmental changes in the bovine whey proteome during the transition from colostrum to milk. The expression patterns of whey protein of days 1 and 3 post-partum were similar except that immunoglobulin G was down-regulated on day 3, and four proteins were found to be down-regulated on days 7 and 21 compared with day 1 after delivering, including immunoglobulin G, immunoglobulin M, albumin, and lactotransferrin, which are involved in immunity and molecule transport. The results of this study confirm the comparative proteomic method has the advantage over other methods such as ELISA and immunoassays in that it can simultaneously detect more differentially expressed proteins. In addition, the difference in composition of milk indicates a need for adjustment of the colostrum feeding regimen to ensure a protective immunological status for newborn calves.

This study evaluated the effects of Glycine soja (GS) and hairy vetch supplementation on the quality of corn silage. The feeding regimen consisted of a corn silage (Control) and a control supplemented either with 20% GS or 20% hairy vetch with four replicates. All experimental diets were stored for 40 days at room temperature ($20-25^{\circ}C$). The control had a higher (p < 0.05) dry matter level but had a lower level (p < 0.05) of crude protein, crude fat, acid detergent fiber and neutral detergent fiber than any other treatments. Hairy vetch had a higher level (p < 0.05) of acetic acid and butyric acid than any other groups but had a lower level (p < 0.05) of lactic acid than that of the control. A lower silage pH was observed (p < 0.05) in the control compared to the other treatments. The control had lower (p < 0.05) sucrose and fructose concentrations compared to the other treatments. Corn silage supplemented with hairy vetch showed a higher level (p < 0.05) of crude protein and buffer solution protein and a higher ratio of soluble protein to insoluble protein than any of the other groups. Thus, the results of the present study suggest that GS and hairy vetch supplementation of corn silage would be beneficial for maintaining quality and elevating protein levels when compared to the control.
The purpose of this study was designed to observe the effects of the feeding Cynanchum wilfordii extract on the improvement of the blood glucose, lipid components in the serum of dietary hyperlipidemic and streptozotocin(STZ) -induced diabetic rats(S.D. strain, ♂) fed the experimental diets for 5 weeks. Concentrations of total cholesterol, atherosclerotic index, LDL, LDL-Cholesterol, free-cholesterol. cholesteryl ester, TG, PL and blood glucose in serum were significantly higher in the cholesterol administration groups((group 2(cholesterol+water), 4(cholesterol+Cynanchum WIlfordii 3.5g% extract)) than those in the control group (group1 , basal diet+water). But the concentrations of total cholesterol. atherosclerotic index, LDL, LDL- cholesterol. free-cholesterol, cholesteryl ester, TG, PL and blood glucose in serum were remakably lower in the group 4 than those in the group 2. In the STZ(55mg/kg B.W.)-induced diabetic groups((group 3(STZ, IP.)+water), 5(STZ(IP.)+Cynanchum WIlfordii 3.5g% extract? the serum total cholesterol, atherosclerotic index, LDL, LDL-cholesterol, free-cholesterol. cholesteryl ester, TG, PL and blood glucose concentrations actions were rather lower in the group 5 than those in the group 3. In the ratio of HDL -cholesterol concentration to total cholesterol and HDL-cholesterol concentration, Cynanchum wilfordii extract administration groups were higher percentage than III the groups 2 and 3. The activities of aspartate aminotransferase(AST), alanine aminotransferase(ALT), alkaline phosphatase (ALP) and lactate dehydrogenase(LDH) in serum were rather lower in the Cynanchum wllfordii extract administration groups (group 4,5) than in the cholesterol diet group(group 2) and STZ-induced diabetic group (group 3). From the above research, the physiological activity substances in Cynanchum wllfordii were effective on the improvement of the blood glucose, lipid compositions in serum of dietary hyperlipidemic and STZ-induced diabetic rats. And particularly, physiological activity substance in Cynanchum wilfordii was more effective therapeutic regimen for the control of metabolic derangements in adult disease.
Public concern on the methods of raising food-producing animals has increased, especially in the last two decades, leading to voluntary and mandated changes in the animal production methods. The primary objective of these changes is to improve the welfare of farm animals. The use of gestational stalls is currently a major welfare issue in swine production. Several studies assessed the welfare of alternative housing systems for gestating sows. A comparative study was performed with gestating sows housed in either individual stalls or in groups in a pen with an electronic sow feeder. This review assessed the welfare of each housing system using physiological, behavioral, and reproductive performance criteria. The current review identified clear advantages and disadvantages of each housing system. Individual stall housing allowed each sow to be given an individually tailored diet without competition, but the sows had behavioral restrictions and showed stereotypical behaviors (e.g., bar biting, nosing, palate grinding, etc.). Group-housed sows had increased opportunities to display such behavior (e.g., ability to move around and social interactions); however, a higher prevalence of aggressive behavior, especially first mixing in static group type, caused a negative impact on longevity (more body lesions, scratch and bite injuries, and lameness, especially in subordinate sows). Conclusively, a more segmented and diversified welfare assessment could be beneficial for a precise evaluation of each housing system for sows. Further efforts should be made to reduce aggression-driven injuries and design housing systems (feeding regimen, floor, bedding, etc.) to improve the welfare of group-housed sows.
Two experiments were conducted to study the effects of nutrient level and feeding method of split diets for a.m. and p.m. on laying hen performance, feed cost and eggshell quality. In experiment 1, 384 ISA Brown layers of 30∼38wk of age were assigned to four treatments which comprise of three replicates each containing 32 birds. The control(C) was fed a conventional single diet throughout the day and split diet groups(T1, T2 and T3) were offered high energy/protein-low Ca diets, and low energy/protein-high Ca diets in a.m.(04:00∼15:00) and p.m.(15:00∼21:00), respectively. In the split diet groups, daily ME and CP consumption, and feed cost were significantly reduced(P<0.05) compared to the C, while the hen-day egg production, average egg weight and daily feed intake were not different among treatments. Due to the reduced daily ME and CP intakes and feed cost, the conversions of feed, ME, CP and feed cost required per day and per kg egg mass were also significantly improved(P<0.05) in the split diet groups. Eggshell qualities (egg specific gravity, egg breaking strength and eggshell thickness) were improved(P<0.05) by split diet feeding. As the Ca level of the p.m. diet increased. In Experiment 2, 384 ISA Brown layers of 50∼58 wk of age were used in three treatments and each treatment was represented by four replicates each containing 32 birds. The control(C) was fed a conventional single diet throughout the day and split diet group(T1) was offered high energy/protein-low Ca diets, and low energy/protein-high Ca diets in a.m.(04:00∼l5:00) and p.m.(15:00∼21:00), respectively. T2 group was fed the diet mixed (50:50) with the a.m. diets in mash and p.m. diet in pellet used T1 group. In T1 and T2 groups, daily feed intake and average egg weight were significantly reduced(P<0.05) compared to the C, while the hen-day egg production was not influenced by the feeding system. Daily ME and CP consumption, and feed cost were reduced(p.0.05), and the conversions of ME, CP and feed cost required per egg were also significantly improved(P<0.05) in T1 and T2, while the conversions of feed, ME, CP and feed cost required per kg egg mass were not different to the C. Eggshell qualities of T1 and T2 were improved(P<0.05) compared to the others. It was concluded the feed and nutrients consumption, feed cost per day or per kg egg mass could be reduced by introducing split diets for a.m. and p.m. and the feeding method of mixed diet of split diets were also convenient and effective for sparing feed cost and improvement of eggshell quality.

The objective of this study was to investigate the effect of dietary supplementation of vitamin C and Sea buckthorn on the performance, blood biochemistry and meat quality in old laying hens. A total 200 Hy-Line Brown laying hens (101 weeks old) were randomly allotted to 1 of 5 dietary treatments : (1) Basal : basal diet, (2) Vit. C : basal diet + 0.1% vitamin C, (3) SB 0.1 : basal diet + 0.1% Sea buckthorn, (4) SB 0.5 : basal diet + 0.5% Sea buckthorn, and (5) SB 1.0 : basal diet + 1.0% Sea buckthorn. Each treatment was replicated 4 times with 10 birds units were arranged according to randomized block design. Feeding trial lasted 4 weeks under 16L:8D lighting regimen. The diets were fed to hens on an ad libitum basis for 4 weeks. Result indicated that during feeding trial of the experiment, hen-day egg production and feed conversion ratio were not significantly influenced by treatments. However, feed intake was significantly (P<0.05) higher in Vit. C and SB treated groups than the basal during 1 wks and 3 wks. Egg weight was significantly (P<0.05) higher in basal and Vit. C than the SB 1.0 treatment. There were no differences in carcass yield during feeding trials. However, partial ratio (breast and neck) was significantly (P<0.05) higher in SB 0.5 than other treatment. There were no differences in the level of leukocytes and erythrocytes. There were no significant differences on proximate analysis (DM, crude protein, crude fat, and crude ash), meat color, water holding capacity, cooking loss, and fatty acids concentrations. In conclusion, dietary supplementation of vitamin C and Sea buckthorn to the diet of old laying hens might be a potential ingredient for increasing partial weight (breast) in old laying hens.
The present study was conducted to determine the effect of energy restricted (ER) diet on the expressions of lipogenic genes in liver and myogenic genes in muscle tissue of broiler chickens. Energy restriction was accomplished by providing chicks with 70% (ER70) or 85% (ER85) energy level of control diet intake. Energy restricted groups of chickens were restricted for 7 days, starting at 8 days of age. Ad libitum feeding was resumed after the restriction period, and continued through the end of the experiment. The body weight of chickens in the restricted groups gained less during the energy restriction period (P<0.05). The body weight of the ER groups were similar to the control group during the re-alimentation period. However, the body weight of the ER70 group did not catch up with that of the control group by 35 days of age. The energy restrictions during early life of chicks decreased the contents of triglycerides and cholesterol in blood (P<0.05), but those were not different among treatments after re-alimentation. The genes of fatty acid synthase (FAS) and transcription factors including SREBP and PPARγ were down regulated by restriction regimen only in ER70 (P<0.05). However, those genes were not completely recovered after re-alimentation in ER70 group. The RNA expression levels of Myo-D, Myf-5 and myogenin in all treatment groups were decreased by restriction regimen when compared with control group (P<0.05). Myogenin was highly expressed after re-alimentation, but the other genes were not different among groups. These results suggest that ER85 group shows the best growth performance by re-alimentation and the higher muscle differentiation by expressing myogenin.

The objective of this experiment was to investigate the effect of dietary supplementation of herbal medication (HM) on laying performance, blood parameter, and immune response in laying hens. A total of 800 Hy-Line Brown laying hens of 60 weeks of age were randomly allotted to one of four dietary treatments with four replicates per treatment. Three additional diets were prepared by adding 0.5, 1.0 or 1.5 % of HM to the basal diet. Feeding trial lasted 7 weeks under 16L:8D lighting regimen. The diet and water were available ad libitum. Hen-day egg production in groups fed diets with 0.5% and 1.5% HM was significantly (P<0.05) higher than that of control. Feed conversion ratio in group fed diet with 0.5% HM showed the lowest value (P<0.05). Egg weight, feed intake, broken and shell-less egg production were not affected HM supplementation levels. Egg yolk color was significantly greater in all HM supplemented groups than basal treatment. However, eggshell strength, eggshell thickness, eggshell color, and Haugh units were not affected by HM supplementation level. There were no differences in leukocyte counts among the treatments. Plamsa IgM concentration was (P<0.05) higher in all HM treated groups. In conclusion, dietary HM improved egg production, and IgM of laying hens.
