  In the present study, as an alternative to antibiotics in broiler diets, microencapsulated-inuloprebiotics extracted from Korean Jerusalem artichoke was manufactured as a natural antimicrobial agents and added to broiler diets after which the quality and storability of chicken meat were investigated. A total of 360, 1 day old Ross 308 broiler chicks were randomly assigned to 3 treatment groups that were each replicated 4 times. The broilers were then divided into T1 (control), T2 (Avilamycin 8 g ton-1) and T3 (inuloprebiotics 250 g ton-1). The pH, water holding capacity and water content of chicken meat was significantly higher in T3 than T1 and T2. Additionally, the L* value (lightness) and b* value (yellowness) of the meat was significantly higher in T3 than T1 and T2. The TBARS value during low temperature storage of chicken thighs was significantly lower in T3 than T1 and T2. Finally, the sensory evaluation scores of the cooked chicken meat were significantly higher in T3 than T1 and T2. The results of this study suggest that the addition of inuloprebiotics as an alternative for antibiotics to broiler diets can greatly improve the quality and the storability of chicken meat.

  In the present study, we investigated the effect of Microencapsulated-Inulin (MCI) in feed on the improvement of the growth performance in broilers using MCI prepared from Korean Jerusalem artichoke as a natural antibacterial growth promoter. After sex identification, 320 male Ross 308 broilers were randomly allotted to treatment groups and fed for 35 days. Treatment groups consisted of T1 (no supplementation; control), T2 (avilamycin, 8 g ton-1), T3 (MCI, 200 g ton-1) and T4 (MCI, 250 g ton-1). The growth performance and the dressing percentage were higher in broilers in groups T3 and T4 than in broilers in groups T1 and T2; statistical significance in the differences among the treatment groups was verified. The weights of breast and thigh muscles were significantly higher in broilers in T3 and T4 than in T1 and T2 and abdominal fat was significantly lower in broilers in T3 and T4 than in T1 and T2 with a decrease of 19.08-23.30%. The levels of blood immunoglobulins, IgG, IgM, IgA and weights of thymus and bursa of fabricius were significantly greater in T3 and T4 compared with T1 and T2 with an increase of IgG, IgM and IgA being 125.1-168.5, 100.5-170.5 and 103.0-125.3%, respectively. The colony counts of the beneficial intestinal microorganisms, Bifidobacteria and Lactobacillus were significantly greater in T3 and T4 than in T1 and T2 but the counts of harmful E. coli and Salmonella were significantly less in T3 and T4 than in T1 and T2. The supplementation of broiler feed with 200 g ton-1 microencapsulated-inulin can significantly improve the productivity of broiler chickens.

  The purpose of this study was to evaluate the effect of the ethanol extract from the grain larvae (GLE: Grain Larvae Ethanol extract) on the blood lipid level of high-fat diet-induced obese rats (Experiment I) and on the protective effect of liver damage in rats that were given intraperitoneal injections of Chlorotetracycline (CCl4) and alcohol (Experiment II). For Experiment I, 27 male rats (SDS strain) were randomized into three treatment groups: NC (Normal Control group fed with chow diet without the administration of GLE), HO (High-fat diet induced Obese group) and HOE (High-fat diet induced Obese rats administered orally with GLE 5.0 mg/100 g body weight). For Experiment II, 45 male rats (SDS strain) were randomized into five treatment groups: T1 (control group), T2 (intraperitoneal injection of CCl4), T3 (oral administration of GLE combined with intraperitoneal injection of CCl4), T4 (combined administration of GLE and alcohol) and T5 (intraperitoneal injection of alcohol combined with oral administration of GLE). Compared with HO, the levels of triglyceride, total cholesterol and LDL-cholesterol in blood decreased significantly in HOE while the HDL-cholesterol level showed a significant increase (p<0.05). Concentrations of AST, ALT, γ-GTP and bilirubin in blood significantly decreased in T3 and T5 groups with oral administration of GLE, compared with T2 and T4 groups (p<0.05). In rats in T3 and T5 groups, recovery of liver tissue cells from damage that had been induced by intraperitoneal injections of CCl4 (T2) and alcohol (T4) could be observed.

  This study has been performed to assess the anti-atopic efficiency in DNCB induced BALB/c to examine a therapeutic effect of Atobeauty cream which was provided by NJY Life Science Co., Ltd. on atopic dermatitis. Such BALB/c mice were provided by NJY Life Science Co., Ltd. The randomized complete block design was done by dividing 20 male mice with BALB/c into two groups of which the one group had 10 mice receiving no treatment as a control group and the other group had 10 mice receiving treatment with Atobeauty cream as a treatment group. When Atobeauty cream was applied to the mouse with severe atopic dermatitis 2 times a day for 6 days, it could be observed that its skin recovered to normal condition with the skin surface being clean and smooth without any horny tissue. It was found that each level of IgE and histamine in blood was significantly decreased by 57.80 and 59.41%, respectively in the Atobeauty cream treatment group (here in after, the treatment group), compared with the DNCB induced atopy control group (here in after, the control group (p<0.05). It was also identified that a mouse with atopic dermatitis to which Atobeauty cream was applied, recovered on the order of a normal mouse as its epidermis got to be softly formed with its surface thickness being even and its connective tissue got to be formed more uniformly.

  The purpose of this study was to examine the effect on lowering LDL-C in a adult human by applying low animal foods with a lower n-6/n-3 ratio. It was found that the n-6/n-3 ratio was significantly lowered in the low Hanwoo beef, the low pork, the low chicken, the low egg and the low milk to 4:1 or below, compared with commercial animal foods (p<0.05). Oleic acid was significantly increased in the low Hanwoo beef, the low chicken, the low egg and the low milk by 11.49, 8.16, 11.25, 2.69 and 24.12%, respectively, compared with commercial animal foods (p<0.05). Compared with the common Hanwoo beef and the low Hanwoo beef, the imported beef showed that the n-6/n-3 ratio was higher by 8.70 and 15.46 times, respectively while oleic acid was significantly decreased by 5.61 and 17.75%, respectively (p<0.05). When commercial animal foods were taken, the blood LDL-C level related with an increase or a decrease of cholesterol was not changed only in the common egg but it was significantly increased in the imported beef, the common Hanwoo beef, the common pork, the common chicken and the common milk by 27,02, 7.85, 25.81, 5.77 and 8.97%, respectively (p<0.05). When low animal foods with lower n-6/n-3 ratio were taken, it was significantly decreased in the low Hanwoo beef, the low pork, the low chicken and the low milk by 22.05, 22.89, 27.55, 12.38 and 14.78%, respectively compared with the imported beef and commercial animal foods (p<0.05).
