Objectives: The aim of this study was to assess how nutrient intakes are related to risk factors for metabolic syndrome according to dietary patterns in the middle-aged adults. Methods: The subjects (n = 187; 47 men, 140 women) consisted of middle-aged adults over 30 years old in Ilsan area. The metabolic syndrome was diagnosed according to the data collected from each subject, including anthropometric measurements and blood analyses. The dietary patterns were derived from the average of two-day dietary intake data. Results: Factor analysis identified three major dietary patterns which were "Meats and alcohol", "Mixed grains, vegetables and fruits", and "Rice, Kimchi and fish & shellfish". The daily intakes of energy, protein, and sodium increased across quartiles of "Meats and alcohol" pattern scores (p < 0.05), whereas the intakes of carbohydrates, potassium, calcium, and fiber increased across quartiles of "Mixed grains, vegetables and fruits" pattern scores (p < 0.001). The "Meats and alcohol" pattern scores were positively correlated with protein and sodium intakes but inversely correlated with carbohydrates, fiber and potassium intakes which were adjusted for age, sex and energy (p < 0.05). The highest quartile pattern score of "Meats and alcohol" pattern had elevated odds ratio of abdominal obesity and metabolic syndrome (p < 0.05). The risk of hypertriglyceridemia decreased in the highest quartile of "Mixed grains, vegetables and fruits" pattern (OR 0.35, 95% CI 0.12-1.00). Conclusions: Our results suggested that reducing the consumption of meat and alcohol along with increasing fruits, vegetables and mixed grains would be helpful for preventing the metabolic syndrome and chronic diseases.
This study was conducted to investigate effects of the brown seaweed waste(BSW) supplementation on milk production and related endocrine response in serum in Holstein dairy cows. A total of 14 Holstein dairy cows(initial mean live weight 625kg, average lactation days 225, Reproduction 2.4) were randomly allocated into control(basal diet) and treatment groups (4% BSW/basal diet) with 7 replications for 90 days. Dry matter intake was not affected by brown seaweed waste supplementation, but daily milk yield(kg) at the last experiment significantly increased (6.25kg) in treatment group compared with control group(p<0.05) at the last experiment. The plasma insulin-like growth factor(IGF)-1, triiodothyronine($T_3$) and thyroxine($T_4$) levels were significantly increased in treatment group compared with control group(p<0.05), although the concentration of plasma growth hormone(GH) was not significantly different. Milk composition was not significantly different between groups. The somatic cell count(SCC) in milk were significantly reduced in treatment group compared with control group(p<0.05), but antibodies(total IgG, G1, G2) were not significantly different between groups. Therefore we strongly believe that the increased milk yield is related to metabolic hormones as IGF-1, $T_3$ and $T_4$ and the mechanism of reducing SCC in milk must do more study related nonspecific immunsystem in the future.
An experiment was conducted to determine the effect of supplementation of chlortetracycline (CTC,110ppm), copper sulfate(Cu, 125ppm) and two levels of probiotics(Prob I, 0.04%, Prob II, 0.1%), Bacillus licheniformis and Bacillus subtilis) on growth performance, nutrient digestibility and manure characteristics in growing pigs. A total of 50 pigs that averaged 20.78$\pm$0.35kg BW and 50$\pm$2.3d age were allocated in a randomized block design with two pigs per pen and 5 pens per treatment. Pigs and feeders were weighed 10-days interval for the 40-d trials to determine ADG, ADFI and feed:gain ratio(F:G). Average daily gain, feed intake, feed/gain and nutrient digestibility were not improved(P>0.10) by the supplementation of CTC, Cu and two levels of probiotics. There were significant(P<0.05) Cu effects on digestibility of crude protein, and probiotics effects on digestibilities on organic matter, crude protein and energy between first 20 days and subsequent 20 days. Fecal concentrations of copper were highly increased(P<0.001) by the copper supplementation. Total bacteria and coliform counts were not altered by the supplementation of CTC, Cu and two levels of probiotics. Ammonia emission from slurry, measured during first 3 weeks, was reduced (P<0.001) in pigs fed diet with 125 ppm copper from copper sulfate. Results indicate that CTC, Cu and Probiotics supplementation had a little or not positive effect on grower pig performance under sound environmental conditions. Further studies may be warranted to investigate the effects of dietary copper-either reduced or in combination with dietary ammonia control agents-on the ammonia emission characteristics of swine manure.
This study was conducted to investigate the effect of single or mixed supplementation of bacterial and fungal phytase using 45-wk-old 450 Hy-Line Brown laying hens housed in individual cages for 12-wk period. The birds were reallocated to have similar egg productivity by examining the egg production for one wk before starting the experiment. Two sources of phytase, bacterial (BP) and fungal (FP), were used either in single or mixture to determine the effects of these phytase. Five dietary treatments consisted of control (BP 0, FP 0), T1 (BP 300, FP 0), T2 (BP 300, FP 300), T3 (BP 300, FP 3000), and T4 (BP 0, FP 3000). The DPU was used for phytase activity in this experiment. The nonphytate phosphorus (NPP) content of control was 0.30%, and those of phytase treatments were set to 60% of the Control. Experimental diets were fed ad libitum throughout the experimental period. The lighting schedule of 17L7D was employed. The egg production was not different between control and bacterial phytase treatments, but the T4 showed significantly low productivity compared to control (P<0.05). No difference was found in average egg weight among all treatments. The daily egg mass did not show any statistical differences among all treatments: however, it was significantly low in T4 compared to ther control during the latter half of the experiment (P<0.05). No significant difference was found among treatments in terms of feed intake, feed conversion and egg quality. The digestibilities of dry matter, crude protein, and fat digestibility were similar regardless of the treatments. No significant trends were detected in Ca and P availability. In conclusion, the BP level of 300 DPU contributed to achieve 40% reduction of recommended nonphytate phosphorus addition. The synergistic effect of bacterial and fungal phytase was not confirmed.

This study was carried out to investigate the effect of mountain grazing on growth performance and carcass characteristics of Hanwoo steers. Thirty two Hanwoo steers were randomly assigned. Control were fed concentrate + forage until 30 month of age. Treatment1 were fed concentrate + forage after mountain grazing from 8 to 13 months. Treatment2 and 3 were fed concentrate + forage after mountain grazing from 8 to 17 months. Hanwoo steers on Treatment 1 and 2 were slaughtered at the same age (30 months) as the control, and Hanwoo steers on Treatment 3 were slaughtered at 31 months. The average daily gain (ADG) were higher in the control than in the other treatments during the growing period (p<0.05). Carcass back fat thickness was thicker in the TRT 3 and marbling score was higher in the TRT 1 than in the other treatments; however, the differences were not statistically significant. There was no difference in the meat composition and shear force of the longissimus muscle according to the mountain grazing. However, the yellowness (b) of fat colors were significantly lower in the control than in the TRT 1 and TRT 2 (p<0.05). The effect of grazing on fatty acid composition was not constant. In conclusion, mountain grazing could reduce meat color without affecting the growth and meat quality of Hanwoo steers, and further research on the quality, yield and intake of grassland would be needed.

This study was conducted to determine the effect of supplemented useful micro-organism on performance and meat quality of growing-finishing pigs for sixty days and broiler for six weeks. The pig and broiler were randomly allotted into 3 treatment; Control 0 (C), T1 (supplemented with $0.2\%$ Aspergillus terreus), T2 (supplemented with $0.2\%$ EM-pro). In total experimental period, feed conversion and dairy feed intake were tend to be higher in T2(2.09kg, 2.70kg) than others. But ADG (average daily gain) was tend to decreased n (0.78kg) according to supplemented of Aspergillus terreus diet These treatments were not significant difference. The chemical composition of pork were not significant difference except for crude fat Crude fat content was lower Aspergillus terreus treatments than others. The pH tenderness, WHC and heating loss were not significant difference in pork $(p>0.05)$. In chicken meat, heating loss and WHC of control was higher than that of T1 and n but shear value was higher in T1 and n. Values of juiciness, tenderness and flavor were improved with highly significant difference (p<0.05) in control (4.95, 4.85, 4.60) than T1 and n in pork. Although the meat color was not significant difference in pork but a and b values of control was higher than that of T1 and n in chicken meat (p<0.05).
This study was conducted to investigate the changes in growth performance, blood hormone levels and immunity of weaning pigs by the installation of warm curtain for keeping warmth in pigpen. A total of sixty-four piglets was weaned at 21 d of age with an average body weight of 5.8 kg. Each thirty-two piglets were allocated into the pens with (TRT) or without warm curtain (CONT). Daily gain and feed intake were increased by 17% and 9% in TRT from 2nd week to 4th week compared with CONT, respectively. The occurrence of diarrhea was decreased by 62% in TRT from initial to 2nd week compared with CONT. There were no significant differences in blood hormone levels and immunity of weaning pigs between treatments. In conclusion, the installation of warm curtain, which supported high temperature in pigpen, was considered to be effective in improving growth performance and reducing diarrhea occurrence of weaning pigs.

This study was conducted to determine the maintenance energy requirements of growing goats in order to establish an appropriate energy benefit system, to reduce feed costs and improve livestock productivity of goat farmers, and to present basic data for detailed specifications afterwards. This experiment was conducted as a group specification test for a total of 3 months, with 32 goats of three months age and conducted by four treatments with different energy levels (T1: NRC+0%, T2: NRC+10%, T3: NRC+20%, and T4: NRC+30%). The average daily gain was the highest in the treated with NRC + 10% of the energy level of the experimental diet, and the feed conversion ratio was in the range of 6.3 g to 7.3 g in the group feeding experiment. Although there was no significant difference in digestibility between treatments, the digestibility of dry matter, crude protein, and crude fat was higher in T2 treated with NRC + 10% than the other treatments. Through the regression equation of the values of MEI and ADG obtained through the experiment (Y=0.5439X+111.51, R2=0.712), the maintenance energy requirement of the goat in the growing period was estimated to be 111.51 kcal/kgBW0.75.
This study was conducted to develope an automatic liquid feeder for early weaning piglets and to test the efficacy of the system. The liquid feeder consists of water heating and discharge unit, dry diet storing and discharge unit, mixing and discharge unit, mixed liquid feed-delivering unit, and the central control part which control each unit, feeding frequency and the amount of feeding. For investigating the possibility of practical use, a feeding trial was carried out using eighteen three way crossbred piglets weaned on 19 days of age for the experimental period of six weeks. Experimental diet was provided in liquid form using the automatic liquid feeder for the first three weeks and in dry form for the later three weeks. The water heating and discharge unit exactly supplied warm water by 27 $m\ell$/s, into the mixing unit. The dry diet storing and discharge unit supplied dry feed by 3.7g/s, into the mixing unit. Being compared with the standard growth rate suggested by NRC, average daily gain of the piglets during the first three weeks of liquid feeding was lower by 10%, while it was higher during three weeks of dry feeding and over the whole experimental period by 24 and 17%, respectively. Feed/gain was 1.09, 2.14 and 1.89 for the first 3 weeks, later 3 weeks, and whole period, respectively. Diarrhea was observed for three days from day 3 to day 7 after feeding liquid diet, but no pig died of it. In conclusion, a preliminary test for the newly developed an automatic liquid feeder using 19 days of age weaning piglets showed that the unit was successfully operated without any major problems. Piglets raised on a liquid diet through the unit developed grew less during the first three weeks, but their growth and feed intake were greatly improved thereafter, indicating the developed automatic liquid feeder may be practically used in swine industry.
