  • This study was conducted to determine the effects of mugwort powder on meat compositions (proximate analysis, meat cholesterol, fatty and amino acid composition) and sensory characteristics in finishing pigs ($LY{\times}D$). Each $20{\times}3$ pigs (75 kg) were randomly allotted to three treatments. Mugwort powder was added for 0 (C), 0.5 (T1), 1.0 (T2), or 1.5% (T3) in basal diet, respectively for 50 days. Moisture, protein, ash, and cholesterol were not significantly different between the samples, however, the compositions of fat in T2 and T3 were significantly lower than the control (p<0.05). The amino acid composition did not differ significantly in the samples. The total sum of saturated fatty acid (SFA) and unsaturated fatty acid (UFA) did not differ significantly in the samples. The compositions of linoleic acid, linolenic acid, essential fatty acid (EFA) and polyunsaturated fatty acid (PUFA) were lowest significantly in T3, however, monounsaturated fatty acid (MUFA) were highest in T3 (p<0.05). The fatty acid compositions of arachidonic acid, EFA and PUFA were highest significantly in T2 (p<0.05). There were no significant differences in the sensory characteristics of fresh and cooked meats in the samples.

  • The goal of this study was to investigate the effects of dietary mugwort on the proximate composition, volatile basic nitrogen (VBN), thiobarbituric acid reactive substance (TBARS) and fatty acid in chicken meats. One hundred sixty broiler chicks (1 d old) were assigned to one or four dietary groups: Control; commercial feed supplemented with 1% mugwort (T1); commercial feed with 3% mugwort (T2) and commercial feed with 5% mugwort (T3). After 42 d, broilers from each group were slaughtered and meat samples were vacuum packaged and stored at $4{\pm}1^{\circ}C$ over a period of 0, 1,2,3, and 4 wk. Chicken breast was not influenced by all treatments in moisture, crude protein and crude fiber, while crude fat was lowered (p<0.05) in chickens fed with the T2 and T3 diets compared to the control and T1 diets. All treatments with mugwort diets tended to have decreased VBN values for chicken breast and thigh compared to control. As storage time increased, VBN was increased for all chickens (p<0.05). No significant differences in TBARS were observed among all treatments at 0 wk. TBARS values were reduced with the T2 and T3 diets and initially increased from 0 through 3 wk, then abruptly decreased at 4 wk. Dietary mugwort supplementation resulted in increased stearic acid (excepted T2) and oleic acid and decreased linoleic acid. Stearic acid in thigh meat was decreased in the T1, T2 and T3, however linoleic acid levels tended to increase with mugwort powder supplementation. It is concluded that dietary mugwort has a positive effect on increasing unsaturated fatty acid contents and decreasing saturated fatty acids.

  • The contents in large intestine of Sprague Dawley rats fed polygalae radix(Polygala tennuifolia), onion(Allium cepa) and mugwort(Artemisia asiatica)-supplemented diets for 14 days were analysed for changes of major intestinal microflora, activities of ${\beta}-glucosidase\;and\;{\beta}-glucuronidase$ and amounts of putrefactive products such as indole and volatile basic nitrogen. The rats having ingested $5%{\sim}10%$ mugwort water or ethanol extract-supplemented diets showed a significant increase in intestinal bifido-bacteria and a decrease in clostridia and E. coli (p<0.05). And 10% onion juice group also showed a similar beneficial microflora change. In 5% mugwort powder-supplemented group, ${\beta}-glucosidase\;and\;{\beta}-glucuronidase$ activities in the intestinal contents were lowered, but the changes were not significant. Indole contents and pH in this group were significantly low compared with that of control (p<0.05). However, the activities of ${\beta}-glucosidase$ in 5% polygalae radix water extract and 10% onion juice-supplemented group and ${\beta}-glucuronidase\;in\;5%{\sim}10%$ mugwort water and ethanol extract-supplemented group were significantly higher than those of control (p<0.05). The intestinal indole contents of rats were significantly increased by feeding diet with water extract of polygalae radix and ethanol extract of mugwort which had brought comparatively large amount of protein in intestine (p<0.05). However, polygalae radix, onion, and mugwort-supplemented group had no effect on volatile basic nitrogen.

  • This study was conducted to determine the effect of feeding dietary mugwort on the beef quality during 14 month(from 14 month to 27 month) with 32 heads of fattening Hanwoo. Fattening Hanwoos were randomly allotted 4 treatments(8 heads/treatment): C-1[(control(0%) of Hanwoo steers)], C-2[(control(0%) of Hanwoo heifers)], T-1(supplemented with mugwort powder 2.0% of Hanwoo steers), T-2(supplemented with mugwort powder 2.0% of Hanwoo heifers). The shear force value and water holding capacity(WHC) of longissimus muscle were the highest in T-1($3.20kg/0.5inch^2$, 54.32%) and cookingloss was in C-2(22.22%) than the others(p<0.05). However, panel test scores of juiciness, tenderness and flavor of longissimus muscle were the highest for T-1(5.20-5.50 point) between the treatment group. The total catechin and epicatechen in longissimus muscle were higher in treatment group(0.43-046 mg/kg, 0.056-0.065 mg/kg) than control group(0.23-0.25 mg/kg, 0.031-0.032 mg/kg)(p<0.05). The content of total fatty acid in longissimus muscle were oleic acid(48.45-47.56%), palmitic acid(29.67-28.86%), stearic acid(9.92-10.82%), palmitoleic acid and myristic acid(4.68-5.49%, 2.48-3.89%) of range. In conclusion, the effects of feeding dietary mugwort of Hanwoo steer were improved the quality beef with highly panel test scores(juiciness, tenderness, flavor) and physical-chemical characteristics(shear force value, WHC).

  • This study was conducted to determine the effect of mugwort powder supplementation on the fattening performance and carcass characteristics during a 14 month period (from 14 months to 27 months after birth) in 32 heads of fattening Hanwoo. Fattening Hanwoos were randomly assigned 4 treatments (8 heads/treatment): C-1 [(control (0%) with Hanwoo steers)], C-2 [(control (0%) with Hanwoo heifers)], T-1 (supplementation with 2.0% mugwort powder with Hanwoo steers) and T-2(supplementation with 2.0% mugwort powder with Hanwoo heifers). The final body weights for C-1, C-2, T-1 and T-2 at 27 months were 648.6kg, 623.1kg, 663.3kg and 620.7kg, respectively. The total gain and the daily gain were highest in the T-1 group (342.4 kg, 0.88 kg). Hanwoo steers were not significantly different from Hanwoo heifers. The feed intake for the C-1, C-2, T-1 and T-2 groups were 9.35 kg, 9.09 kg, 10.08 kg and 9.69 kg, with the T-1 value being highest. The feed conversion ratios were as follows: C-1 (11.28) > T-1 (11.48) > C-2 (11.52) > T-2 (12.57). The concentrations of total cholesterol, GOT, GPT, glucose and BUN in blood serum during the fattening period were higher after than before the experiment The total cholesterol, GOT and glucose after completion of the experiment were higher in the treatment groups than the control groups (p<0.05). The carcass body weight was higher in the treatment groups than the control groups. The back fat thickness was lower in the treatment groups (12.75-14.75mm) than the control groups (15.76-16.00mm), and the longissimus muscle area was higher in the treatment groups $(84.25-87.88cm^2)$ than the control groups $(84.00-85.25cm^2)$ with the highest over-all values in the T-1 group (p<0.05). The yield grade and quality grade point were higher in the treatment groups (2.02-2.50, 2.85-3.05 point, respectively) than the control groups (1.80, 2.55-2.80 point, respectively). In conclusion, the effects of feeding dietary mugwort powder to Hanwoo steers improved the ADG, carcass body weight, longissimus muscle area and quality grade.

  • This study was performed to manufacture guarasulgies for using in diet therapy by adding various ingredients (mugwort, Angelica gigantis Radis, cinnamon, cocoa powder) to decrease the flavor of guar gum itself and enhance the texture of guarsulgies. The sensory characteristics of guarsulgies added these ingredients wee investigated to decide the maximum acceptable addition levels. The maximum acceptable addition levels of these ingredients was 3.75% for mugwort, 3% for Angelica gigantis Radis, 2% for cinnomon or 0.75% for cocoa. In the texturemeter measure for guarsulgies added cocoa, springness, gumminess, hardness, and chewiness tended to increase compared to other guarsulgies. We concluded that guarsulgies added mugowrt, Angelical gigantis Radis, cinnomon, and cocoa would be much better sanacks for diabetes and obese people than plain guarsulgies.

  • This feeding experiment was conducted to investigate the effects of dietary inclusion of various additives on growth performance, hematological parameters, fatty acid composition, gene expression and histopathological changes in juvenile olive flounder (Paralichthys olivaceus). Eleven isonitrogenous (49% crude protein) and isolipidic (10% crude lipid) experimental diets were formulated: no additives (Con); 5% kelp meal (Ke); 10% krill meal (Kr); 1% garlic powder (Ga); 1% citrus meal (Ci); 3% onion powder (On); 1% ginger powder (Gi); 1% mugwort powder (Mu); 1% licorice powder (Li); 1% wasabi powder (Wa); and a mixture (Mix) of these additives. Three replicate groups of juvenile flounder (average weight of 8.5 g) were fed one of the experimental diets to visual satiety twice a day for 15 weeks. The dietary inclusion of additives did not affect survival, weight gain, specific growth rate feed efficiency, daily feed intake, daily protein intake, protein efficiency ratio, hepatosomatic index and visceralsomatic index of the fish. Plasma triglyceride levels were significantly lower in fish fed the Ke, Ga, On, Gi, Mu, Li, and Mix diets than in fish fed the control diet. Plasma glucose, glutamic oxaloacetic transaminase and total cholesterol did not differ among dietary treatments. No significant difference was observed in fatty acid composition and lipid content of the dorsal muscle in fish fed the experimental diets. Myosin gene expression did not differ significantly among treatments after 5 weeks but was significantly lower in fish fed the Kr, Ci, Li, and Mix diets than in control group after 15 weeks. Histopathological analysis showed mild gill hyperplasia and mild necrosis of liver parenchymal cells in several individuals of each experimental group. These conditions were also observed in the control group and were not thought to be related to the inclusion of feed additives. The present findings indicate that the dietary inclusion of additives did not affect growth performance, fatty acid composition, gene expression, and histopathological changes in juvenile flounder. However, plasma triglyceride content may be reduced by supplementation with 5% kelp meal, 3% onion powder, 1% garlic powder, 1% ginger powder, 1% mugwort powder, and the additive mixture.

  • While there are persistent rumors that the consumption of goat meat dishes increases blood pressure, there is no scientific evidence to support this. Two experiments were conducted to clarify whether or not blood pressure increases in conjunction with the consumption of goat meat dishes. In experiment 1, 24 Dahl/Iwai rats (15 weeks old, body weight $309.3{\pm}11.1$ g) were evenly separated into 4 groups. The control group (CP) was fed a diet containing 20% chicken and 0.3% salt on a dry matter basis. The goat meat group (GM) was fed a diet containing 20% goat meat and 0.3% salt. The goat meat/salt group (GS) was fed a diet containing 20% goat meant and 3% to 4% salt. The Okinawan mugwort (Artemisia Princeps Pampan)/salt group (GY) was fed a diet containing 20% goat meat, 3% to 4% salt and 5% of freeze-dried mugwort powder. The experiment 1 ran for a period of 14 weeks during which time the blood pressure of the animals was recorded. The GS, and GY groups consumed significantly more water (p<0.01) than the CP and GM groups despite the fact that their diet consumption levels were similar. The body weight of animals in the CP, GM, and GS groups was similar while the animals in the GY group were significantly smaller (p<0.01). The blood pressure in the GM group was virtually the same as the CP group throughout the course of the experiment. In contrast, while the blood pressure of the animals in the GS and GY group from 15 to 19 weeks old was the same as the CP group, their blood pressures were significantly higher (p<0.01) after 20 weeks of age. The GY group tended to have lower blood pressure than the GS group. In experiment 2, in order to clarify whether or not the increase in blood pressure in the GS group and the GY group in experiment 1 was caused by an excessive intake of salt, the effects on blood pressure of a reduction of salt in diet were investigated. When amount of salt in the diet of the GS and GY group was reduced from 4% to 0.3%, the animal's blood pressure returned to normotensive. These results indicate that, as in the case of chicken consumption, prolonged consumption of goat meat does not cause increased blood pressure, rather the large amount of salt used in the preparation of goat meat dishes is responsible for the increase in blood pressure.
