  • This study was performed to evaluate the effect of the level of stocking density of housing with or without window on chicken meat quality. The incidence of $1^+$ grade of whole chicken housed with window significantly influenced by stocking density. The incidence of $1^+$ grade chicken at high stocking density ($0.050\;m^2$/head), standard stocking density ($0.066\;m^2$/head), and low stocking density ($0.083\;m^2$/head) was 26, 52, and 66%, respectively. Breast muscle of chicken housed with window and with low stocking density showed higher incidence of $1^+$ grade than high stocking density. Also minor and severe PSE (pale, soft, extractive) incidence of chicken meat were showed 4% each, while the $1^+$ grade chicken was not appeared at low density. In chicken thigh, the incidence rate was not affected by stocking density. In chicken housed without window, the incidence of $1^+$ grade chicken in high, standard, and low stocking density was 18, 8, and 46%, respectively. Also, the incidence of $1^+$ grade chicken breast was 2.6 times higher than the chicken in low stocking density. However, incidence of $1^+$ grade thigh was not affected by the stocking density. These results suggest that high stocking density significantly reduced the incidence of $1^+$ grade chicken meat regardless of housing with or without window.

  • In this experiment, 5 treatments consisted of control, probiotics (0.2%; T1), illite (1.0%; T2), activated carbon (1.0%; T3), and hardwood vinegar (1.0%; T4) as diets of chicken were evaluated for 35 days through feeding of 200 male chickens (Arbor Acre Broiler). Thigh muscle from slaughtered chickens were analyzed on pH, volatile basic nitrogen (VBN), thiobarbituric acid reactive substance (TBARS), shear force, and meat color during 10 d of cold storage at $4{\pm}1^{\circ}C$. Groups of T3 and T4 showed higher pH levels compared to the control group, and T4 showed significantly higher value. Over the storage period, all treatment groups showed increase in pH (p<0.05). Values of VBN of T1, T3, and T4 were lower than those of the control group and T2 up to 7 d of storage (p<0.05), but there was no significance at 10 d of storage. Values of TBARS of T3 and T4 were lower than the control group, T1, and T2, while all treated groups showed rapid increase of TBARS values over storage period (p<0.05). Shear force did not show significant difference among treated groups, but it was decreased over storage. Lightness of meat color (L) in treated groups was higher than the control, and T4 showed the highest value during entire storage period (p<0.05). Yellowness levels (b) of T3 and T4 were higher than the control group. These results may suggest the improvement of chicken meat quality and shelf life via the addition 1% activated carbon and 1% hardwood vinegar into feed.

  • A component of pine bark extract, pitamin, is known as an antioxidant and antimicrobial agent that exerts a variety of physiological effects; this compound has also been used widely in human beings. A 35-day trial was conducted to determine the influence of dietary pitamin premix via a sensory evaluation and evaluations of the TBARS, and meat quality in broiler chicken. We used 4 treatments groups: Control, Antibiotics, Pitamin premix 0.1%, and Pitamin premix 0.2%. The amino acid and protein contents in chicken breast muscle did not differ among the treatment groups. The pH of broilers fed on diets containing pitamin premix was lower (p<0.05) than broilers fed on the control and antibiotics diets, whereas the WHC was significantly higher in chicken breast muscles fed on the diet containing pitamin premix compared to the control and antibiotics groups (p<0.05). The TBARS is intended to be increased during the storage period (in days), and was significantly lower (p<0.05) in the chicken thigh muscles with skin from broilers fed on the diet containing the pitamin premix as compared to the control and antibiotics group (p<0.05). The sensory evaluation of boiled chicken, with the exception of the antibiotics group, revealed significantly better results from chickens fed on diets containing pitamin premix than the control group (p<0.05). These results suggest that dietary pitamin premix may improve the shelf life, flavor, taste, and meat quality in broiler chicken.

  • The present study furthered this research by determining the optimal level of inuloprebiotics derived from Korean Jerusalem artichoke to promote growth in broiler chickens. On hatch day, 320 male Ross 308 broilers were randomly allotted to four groups for a 35-day feeding regimen. The groups were a control (no supplementation), diet supplementation with antibiotics (8 ppm avilamycin), supplementation with 200 ppm inuloprebiotics, and supplementation with 250 ppm inuloprebiotics. Body weight and feed intake were comparably high in the two inuloprebiotics groups, and exceeded the values for the control and antibiotics groups. Body weight and feed intake was higher in chickens fed the antibiotics supplemented diet, compared to controls. There were significant differences among treatment groups. Feed conversion ratio during total experimental periods was significantly high in the control group compared to the inuloprebiotics-fed groups, but no significant difference was evident using antibiotics or inuloprebiotics dietary supplementation. Carcass weight, dressing percentage, and weight of breast and thigh muscle were significantly higher for inuloprebiotics-fed chickens, compared with control and antibiotic-fed chickens. Inuloprebiotics concentration was not significant, while antibiotics-fed chickens displayed significantly higher values than control chickens. Abdominal fat was significantly reduced (19.08%-23.30%) and blood immunoglobulin and the weight of the thymus and Bursa of Fabricius were significantly increased in chickens receiving inuloprebiotics-supplemented feed, compared to control and antibiotics fed groups. In the lower intestine, the viable counts of beneficial bacteria (Bifidobacteria and Lactobacillus) were significantly increased and counts of harmful bacteria (Escherichia coli and Salmonella sp.) were significantly decreased in the presence of the inuloprebiotics, compared to control and antibiotic. The present results support 200 ppm as an optimal level of Korean Jerusalem artichoke-derived inuloprebiotics as a dietary supplement to improve growth in broiler chickens.

  • Cellulose has been widely applied into various medical fields including scaffolding, tissue engineering and tissue formation. In this study, we manufactured cellulose medical fiber from Styela clava tunics(SCT-CS) and analyzed the tensile strength, elongation at break, fluid uptake and surface morphology. And then, the biocompatibility and toxicity of SCT-CS were measured in Sprague-Dawley(SD) rats after the implantation for 30, 60 and 90 days. The level of tensile strength and fluid uptake were lower in SCT-CS than chromic catgut(CCG), while elongation at break level were maintained the higher in SCT-CS. Also, the roughness with pronounced surface patterns as a result of in vivo degradation was significantly greater in CCG than this of SCT-CS although these levels gradually appeared with time in both groups. After implantation for 90 days, SCT-CS and CCG was successfully implanted around muscle of thigh without any significant immune response. Furthermore, no significant alterations were measured in serum parameters and the specific pathological features induced by most toxic compounds for liver and kidney toxicity. Therefore, these results suggest that SCT-CS showing good biocompatibility and non-toxicity can be successfully prepared from cellulose powder of SCT as well as has the potential for use as a powerful biomaterial for medical sutures.

  • A 35-day trial was carried out to determine the influence of dietary cinnamon powder (CNP) on the sensory evaluation and quality of chicken meat, carcass characteristics, plasma lipid level and growth performance of broiler chickens. There were 5 treatment groups: control; CNP 2.0%; CNP 3.0%; CNP 4.0%; and CNP 5.0%. The body weight of the broilers fed the diets containing 3.0% CNP was higher than the broilers fed the control feeds (p<0.05). The concentration of triacylglyceride, HDL-C was higher in the plasma from broiler chickens fed diets with CNP (p<0.05) but the concentrations of total cholesterol and LDL-C were significantly lower (p<0.05) compared to the control group. The carcass percentage, chicken breast and thigh weight were not different between the CNP and control groups. The WHC was significantly higher in the chickens fed 4% CNP diet, while the TBARS was significantly lower (p<0.05) in the chickens fed 3% CNP diet compared to the control group. The color of the breast muscle from the chickens fed 3% CNP diet was lighter than those from the control groups (p<0.05). The sensory evaluation of the taste and savor related to CNP in fried or boiled chicken meat were significantly better from the broiler chicken fed diets containing CNP than the control group (p<0.05). These results suggest that dietary cinnamon powder may improve savor and quality of chicken meat in broiler chickens.

  • Reflex sympathetic dystrophy is a syndrome characterized by persistent, burning pain, hyperpathia, allodynia & hyperaesthesia in an extremity, with concurrent evidence of autonomic nervous system dysfunction. It generally develops after nerve injury, trauma, surgery, et al. The most successful therapies are directed towards blocking the sympathetic intervention to the affected extremity by regional sympathetic ganglion block or Bier block with sympathetic blocker; other traditional treatments include transcutaneous electrical stimulation, immobilization with cast & splint, physical therapy, psychotherapy, administration of sympathetic blocker, calcitonin, corticosteroid and analgesic agents. The purpose of this report is to evaluate and describe the effects of magnetic resonance following unsatisfactory results with traditional treatments of RSD. A 17 year old female patient, 1 year earlier, had received excision and drainage of pus at the right femoral triangle due to an injury caused by a stone. Afterwards, she experienced burning pain, knee joint stiffness, and muscle dystrophy of the right thigh, especially when standing and walking. Despite a year of number of traditional treatments such as: lumbar sympathetic block, continuous epidural analgesia, transcutaneous electrical stimulation, & administration of predisolone, her pain did not improve. Surprisingly, the patients was able to walk free from pain and difficulty after just one application of magnetic resonance. The patient has been successfully treated with further treatment of two to three times a week for approximately ten weeks. More recently, magnetic resonance has been demonstrated to produce effective results for the relief of pain in a variety of diseases. From our experiences we recognize magnetic resonance as a therapeutic modality which can provide excellent results for the treatment of RSD. It has been suggested that polysynaptic reflex which are disturbed in RSD may be modulated normally on the spinal cord level through the application of magnetic resonance.

  • This study was conducted to evaluate the effects of dietary Korean red pine bark extract as an antibiotic replacement on cecum microflora, immune functions, blood lipids, carcass characteristics, and growth performance in broiler chickens. There were four treatment groups: a control group, an antibiotic group, and two treatment groups receiving 65 and 80 ppm Korean red pine bark extract. Growth performance, carcass weight, dressing percentage, and breast and thigh muscle weight of the broiler chickens fed 80 ppm of red pine bark extract was higher than the broilers of the control group and the antibiotic group. Abdominal fat was lower in both groups of broiler chickens fed red pine bark extract, but the growth of immune organs such as the thymus, spleen, and bursa of Fabricius was significantly higher in the group that received a diet supplemented with 80 ppm red pine bark extract than in the control group and antibiotic group. Concentrations of triacylglyceride and total cholesterol were significantly lower in both groups that received red pine bark extract when compared to the control group and the antibiotic group. The concentration of serum IgG was significantly higher in the 80 ppm red pine bark extract group than in the control group and the antibiotic group. The numbers of Bifidobacterium and Lactobacillus in the cecum digesta were significantly increased, while the numbers of Escherichia coli and Salmonella were significantly reduced in the group that received 80 ppm red pine bark extract when compared to the control group and the antibiotic group. These results suggest that the a diet with 80 ppm Korean red pine bark extract as a replacement for antibiotics improve the cecum microflora, immune functions, blood lipids, carcass characteristics and growth performance of broiler chickens.
