This study explored the effect of increased feed intake during the late gestation on the reproductive performance of sows, and fecal score in sows and piglets. A total of 21 crossbred [Landrace × Yorkshire] multiparous sows were randomly distributed into three treatments with seven replicates per treatment. Treatments: CON, 2.4 kg/day; TRT1, 3.2 kg/day; TRT2 , 3.6 kg/day. Body weight and body condition score of sow in different stages were not altered (p > 0.05) due to extra feed in late gestation. A linearly higher (p < 0.05) difference in backfat thickness during farrowing was found in this study. Average daily feed intake was increased (p < 0.05) linearly with extra feed in this experiment. The weaning body weight of piglets was increased (p < 0.05) with extra feed in the sow. The fecal score of sows and their piglets was similar (p > 0.05) in different levels of feed intake. In conclusion, extra feed to gestation sow showed a beneficial effect on improving the weaning piglet's body weight. Although there is a small improvement in the body weight of weaning pigs of sow fed 3.6 kg feed/day in the late gestation period, it is unlikely to be profitable enough to justify the additional waste of feed.

This study investigated the correlation of physique factor( standing height, body weight, chest girth, body surface ) and vital capacity upon records of swimming discipline at sea water. The subjects are 194 sophomore students of Korea Maritime University who participated in the swimming discipline. The swimming records were divided into three groups - higher, middle and lower group. The results from this investigation are as follow ; 1. The standing height was above the average on the A, B+ record, body weight was above on the A+, A record, and vital capacity was above on the A+, A, B+, C record respectively. 2. The standing height, body weight, chest girth, body surface, vital capacity was significantly correlated between record P < 0.05 and P < 0.01. Therefore the higher record group has better physique factor and vital capacity than the middle or lower record group. 3. The standing higher of the higher record group was significantly correlated with body weight(0.514), body surface(0.768) and vital capacity(0.427), and body weight was significantly correlated with chest girth(0.525), body surface(0.940) and vital capacity. This standing heiht of the middle record group was sigificantly correlated with body weight(0.509) and body surface(0.779), and body weight was significantly orrelated with chest grith(0.618) and body surface(0.927). The standing height of the lower record group was significantly correlated with body weight(0.595), chest grith(0.363), body surface(0.802) and vital capacity(0.250), and body weight was significantly correlated with chest grith(0.678) and body surface(0.952).

Obesity treatment efficiency can be increased by targeting both central and peripheral pathways. In a previous study, we identified two natural compounds (hispidulin and p-synephrine) that affect adipocyte differentiation. We tested whether obesity treatment efficiency may be improved by adding an appetite-controlling agent to the treatment in the present study. Alkaloids, such as p-octopamine, are adrenergic agonists and are thus used as dietary supplements to achieve weight loss. Here, we assessed anti-obesity effects of a mixture of p-synephrine, p-octopamine HCl, and hispidulin (SOH) on murine preadipocyte cells and on mice receiving a high-fat diet (HFD). SOH showed stronger inhibition of the formation of red-stained lipid droplets than co-treatment with hispidulin and p-synephrine. Moreover, SOH reduced the expression of adipogenic marker proteins, including CCAAT/enhancer-binding protein alpha, CCAAT/enhancer-binding protein beta, and peroxisome proliferator-activated receptor gamma. In the HFD-induced obesity model, body weight and dietary intake were lower in mice treated with SOH than in the controls. Additionally, liver weight and the levels of alanine aminotransferase and total cholesterol were lower in SOH-treated mice than in the controls. In conclusion, our results suggest that consumption of SOH may be a potential alternative strategy to counteract obesity.

This work was carried out to study the carcass characteristics, the chemical composition and the fatty acid profile in Longissimus muscle (LM) of bull breeds Nellore, NEL (11), Caracu, CAR (12) and Holstein-Friesian, HFR (12) finished in a feedlot. The bulls were fed twice a day with corn silage, cotton meal, cracked corn, urea, limestone and mineral salt. NEL and CAR bulls had similar (p>0.05) final weight and hot carcass weight. However, NEL and CAR bulls had higher (p<0.05) final weight and hot carcass weight than HFR bulls. Carcass hot dressing, carcass conformation, cushion thickness, Longissimus muscle area and texture were similar (p>0.05) among NEL, CAR and HFR bulls. NEL and HFR bulls had higher (p<0.05) carcass length in comparison to the CAR breed. Nellore breed had higher (p<0.05) leg length in comparison to CAR and HFR breeds. Leg length was similar (p>0.05) between CAR and HFR breeds. Thickness fat, color and marbling score were lower (p<0.05) in NEL breed in comparison to CAR and HFR breeds. LM of NEL bulls had higher (p<0.05) meat moisture content in comparison to CAR and HFR bulls. In contrast, lipid content was lower (p<0.10) in HFR bulls. LM ash and crude protein contents were similar (p>0.05) among breeds. Saturated fatty acids (SFA) were higher (p<0.10) in HFR animals. Monounsaturated fatty acids (MUFA), polyunsaturated fatty acids (PUFA), n-6, n-3 and PUFA/SFA ratio were similar (p>0.05) among the different breeds. N-6/n-3 ratio was higher (p<0.05) in CAR animals.

Our study analyzed the carcass properties of 170 Korean native pigs in relation to carcass weight and back-fat thickness to provide general data for the production and distribution of high quality pig meat. The 70-74 kg group showed highest yield (73.41%). The ${\geq}80kg$ group showed the highest thickest back-fat (24.13 mm) (p<0.05). The ${\geq}80kg$ group showed the best quality grade (1.00). Back-fat thickness showed significant differences in the weight among groups (p<0.05). The ${\geq}25mm$ group showed the highest carcass weight (75.93 kg). The thickest back-fat group (${\geq}25mm$) showed the highest yield (73.03%). There were significant differences in back-fat thickness among groups (p<0.05), and the ${\geq}25mm$ group showed the highest thickness back-fat (27.60 mm). We found a strong positive correlation between carcass weight and back-fat thickness (r=0.346) as well as meat quality grade (r=0.739). Backfat thickness had a relatively strong positive correlation with meat quality grade (r=0.444). Therefore, there are required to manage the breeding through selection of excellent native species for increasing their carcass weight and enhance meat quality.

Purpose : The study was to evaluate the weight distribution, balance and gait function of stroke patients wearing lateral wedged insole to the shoe of the affected side. Methods : 27 patients with stroke (15 men, 12 women) participated in this study. Participants performed weight distribution, dynamic balance and gait ability with or without wedged insole on affected side in a random order. The balancia was used to evaluate the weight distribution. Deviation from the center line was analyzed by Dartfish during sit to stand to evaluate dynamic balance. The functional walk ability evaluated by 10 m walking velocity. Results : The asymmetry index of weight bearing improved significantly with wedged insole of affected side(p<.05). During sit to stand, center of gravity significantly moved from non-affected side to more mid line of body(p<.05). Improvement were shown in walking speed after wearing the wedged insole(p<.05). Conclusion : Wedged insole applied on affected side have a beneficial effect on weight distribution, dynamic balance and walking speed with stroke.

Purpose: We evaluated the relationship of prostate-specific antigen (PSA) and obesity indices (weight, body mass index [BMI] and waist circumference [WC]) in Korean middle-aged men. Materials and Methods: From February to September 2013, 1,900 police men under 60 years old who participated in a prostate health screening program were included this cross-sectional study. All subjects underwent clinical examinations including weight, height, BMI, WC, fasting blood sugar, lipid profiles, estimated glomerular filtration rate (GFR), and PSA. Total prostate volume (TPV) was assessed clinically. Spearman correlation and multiple linear regression tests were performed to evaluate the obesity indices and PSA relationships. Results: The mean age was $52.0{\pm}4.7years$, and the mean PSA was $0.97{\pm}0.99ng/mL$. The PSA showed a significant positive correlation with the age (r=0.108, p<0.01), TPV (r=0.349, p<0.01), height (r=-0.052, p<0.05), weight (r=0.186, p<0.05), low-density lipoprotein cholesterol (r=0.056, p<0.05), and GFR (r=-0.096, p<0.01). All obesity indices including weight, BMI, and WC showed negative correlations with PSA (beta=-0.013, p<0.001; beta=-0.039, p<0.001; and beta=-0.010, p=0.005; respectively) in age and TPV-adjusted model. Conclusions: Common obesity indices (weight, BMI, and WC) were associated with lower PSA in Korean middle-aged population. Thus, an individual's degree of obesity should be considered when PSA is checked in the first prostate cancer screening of life.

This study aims at examining perception of body weight control and lifestyles and food habits of under-weight, normal-weight and over-weight female college students. The data analysis were conducted by a body fat analyzer and questionnaires. The subjects were 368 female college students divided into three groups: the under-weight(UW), the normal-weight(NW), and the over-weight(OW), according to the guidelines of the Korean Society for the Study of Obesity(2000). Among the subjects, 18.2% were under-weight, 63.6% normal-weight, and 18.2% over-weight. Mean of body weights were 45.4kg, 53.3kg, and 63.7kg, and BMIs were $17.5kg/m^2$, $20.5kg/m^2$ and $24.6kg/m^2$ in the UW, NW, and OW groups, respectively. 'Self assessment of body weight' was significant at the level of p<0.001 according to the Obesity Index. Of the UW group, 41.8% considered their weight to be normal and 4.5% believed they are over-weight. In the NW group, 43.2% thought they are over-weight, 1.5% believed they are under-weight. 57.1 % of the UW group and 98.6% of the NW group had ever tried to reduce their weight. Their 'exercise frequency and exercise time' were not significant by the 01. 'Regularity in the daily life' of the subjects was significant at the level of p<0.05. 43.3 % of the OW group answered that they don't live regular daily lives. 'Sleeping time' of the subjects was significant at the level of p<0.05 by the 01. 41.8% of the OW group reported that they sleep 'between 7 and 8 hours a day' which was the highest rate among the three groups. 'Frequency of meals per day' was not significant by the OI. 'The speed of eating meals' was significant at p<0.01, 23.9% of the UW group, 31.2% of NW group, and 38.8% of OW group reported that they have meals 'in a very fast speed'. Concludingly, most of female college students conceive themselves as having inappropriate body image, which means that they need to be given additional education about nutrition and diet.

Salmon oil (SO) could be used as a great source of ω-3 fatty acids in pig diet. The purpose of the study was to investigate the SO effect on production performance of sows and their offspring. 48 lactating sows (Landrace × Yorkshire) from Dankook University experimental farm were used in this study. Sows were conceived using either guided natural mating or by artificial insemination. Pregnancy diagnosis was confirmed by ultrasonography on day 25 after mating. Sows and their offspring were assigned randomly to 1 of 2 treatments. Treatments included: 1), control (CON); 2), control + SO 0.5% (CS). The inclusion of SO did not affect (p > 0.05) the litter size throughout the experiment. No difference (p > 0.05) was observed on the average daily feed intake (ADFI), chest circumference, estrus interval and sow backfat thickness between CON and SO treatments. Dietary SO supplemented diet reduced (p < 0.05) body weight loss during lactation compared with control treatment. Pigs fed SO supplemented diet did not affect (p > 0.05) the fecal scores during lactation compared with those fed control treatments. Sows fed SO supplemented diet led to a higher (p < 0.05) initial weight, weaning weight and average daily gain of piglets than those fed control diets. No difference (p > 0.05) was observed on piglet survival and fecal scores throughout the experiment. Inclusion of SO could reduce the body weight loss of sows and improves piglet growth during lactation, indicating SO has beneficial effects for pigs.
