Livestock production costs are heavily influenced by the cost of feed, The use of domestically grown forages is more desirable for livestock feed production. As part of this study, triticale, which is an extremely palatable and easily cultivable crop in Korea, was used to produce low moisture silage bales with lactic acid bacteria (LAB) and then stored for different periods. We examined the nutrient content of silage, such as crude protein (CP), acid detergent fiber (ADF) and neutral detergent fiber (NDF), as well as their organic acids, including lactic acid, acetic acid, butyric acid, at different storage periods. The nutrient content of silages, such as crude protein, ADF, and NDF, did not change significantly throughout storage periods. Organic acid data indicated that lactic acid concentrations increased with increasing moisture contents and storage periods up to nine months. However, further extending storage to 12 months resulted in a reduction in the lactic acid content of all silages as well as an increase in their pH. Based on the present results, it suggested that the production of low moisture silage with the LAB may be able to preserve and maintain its quality without altering its nutritional composition. Also, the lactate content of the silage remained significant for at least nine months.

This study was performed to investigate the effect of heat-stressed environment on rumen microbial diversity in Holstein cows. Rectal temperature and respiration rate were measured and rumen fluid was collected under normal environment (NE; Temperature humidity index (THI)=64.6) and heat-stressed environment (HE; THI=87.2) from 10 Holstein cows (60±17.7 months, 717±64.4 kg) fed on the basis of dairy feeding management in National Institute of Animal Science. The rumen bacteria diversity was analyzed by using the Illumina HiSeq™ 4000 platform. The rectal temperature and respiratory rate were increased by 1.5ﾟC and 53 breaths/min in HE compared to that in NE, respectively. In this study, HE exposure induced significant changes of ruminal microbe. At phylum level, Fibrobacteres were increased in HE. At genus level, Ruminococcaceae bacterium P7 and YAD3003, Butyrivibrio sp. AE2032, Erysipelotrichaceae bacterium NK3D112, Bifidobacterium pseudolongum, Lachnospiraceae bacterium FE2018, XBB2008, and AC2029, Eubacterium celulosolvens, Clostridium hathewayi, and Butyrivibrio hungatei were decreased in HE, while Choristoneura murinana nucleopolyhedrovirus, Calothrix parasitica, Nostoc sp. KVJ20, Anabaena sp. ATCC 33047, Fibrobacter sp. UWB13 and sp. UWB5, Lachnospiraceae bacterium G41, and Xanthomonas arboricola were increased in HE. In conclusion, HE might have an effect to change the rumen microbial community in Holstein cows.

Lactic acid bacteria (LAB) were isolated and analysed its fermentation ability in triticale powder at different moisture levels. Furthermore, the antibacterial activity of fermented silage extract against cattle pathogens was also studied. The isolated strains were P. pentosaceus (TC48) and L. brevis (TC50) that confirmed based on biochemical and 16srRNA sequences methods. Extract from LAB fermented silage showed higher antibacterial activity (inhibition zone diameters: 18~24.2 mm) against E. coli P. aeruoginosa, S. aureus and E. Fecalis than the non-inoculated silage extract. TC48 and TC52 strains exhibited high tolerance to artificial gastric, duodenal and intestinal fluids. In summary, lactic acid bacteria mediated fermentation of triticale silage extract showed great antibacterial activity with significant probiotic characteristics might be an effective and safe way to provide new strategies for reducing the incidence of pathogenic bacteria associated diseases in animals.

The consumption of pre-treated vegetables (including fresh-cut vegetables) has been significantly increased because of their ease of use for cooking. Vegetable cutting machine has been widely utilized for producing fresh-cut vegetables or agricultural products with different sizes; however, its design standard is not specifically established depending on types of agricultural products. Therefore, this study was conducted to determine mechanical properties (compressive and shear force) of targeted agricultural products (radish, carrot, squash, cucumber, shiitake mushroom and sweet potato) for developing multipurpose vegetable cutting machine. According to ASAE standard (s368.3), compressive and shear force of targeted agricultural products were measured by using custom built UTM (universal testing machine). Shape type of samples and speed ranges (5~15 mm/min) of loading rate on bioyield and shear points were varied by targeted agricultural products. The range of averaged bioyield points of targeted agricultural products were between 7.89 and 146.98 N. On the other hands, their averaged shear points were from 22.50 to 53.47 N. Results clearly showed that the bioyield and shear points of targeted agricultural products were thoroughly affected by their components. As accumulating compressive and shear points of agricultural products, it can be technical feasible to establish the design standard and control mechanism of multipurpose vegetable cutting machine.

In such special or precious occasions as a wedding ceremony, brides, handicapped or not, wish to wear a beautiful wedding dress. However, an ordinary wedding dress is not suitable nor convenient to a bride who has a bodily impediment. A one-piece type wedding dress, which even a normal bride needs assistants to help her wear, will create more inconvenience to crippled females. In this connection, this study is purposed to convert a normal ready-made wedding dress design into one suitable to the bodily handicapped females. For handicapped people on a wheelchair who generally put on and off a wedding dress while sitting on the chair, a one-piece type wedding dress is divided into the top and the skirt to make it a two-piece type wedding dress which is easy to get into and take off. The top should be separated from the skirt in such a manner that the wearer may not be aware of the division of the two pieces but easily put on and off since the sides or back of the top is opened. An opening is also given to the sides of the skirt so that handicapped people may sit on the skirt on the chair and then close the opening by themselves. Converting ready-made wedding dress design into functional clothes for handicapped people is really significant in that ready-made clothes can be recycled, their production cost reduced, and the economic burden of handicapped people relieved.

This study aims to identify DNA marker related to health index which is derived from fatty acid composition of Hanwoo meat. We investigated a genetic association between two SNPs (-867G>C and 878C>T) of SCD gene and health indexes. Two health index values (index of atherogenicity and index of thrombogenicity) were derived from a combination of fatty acid composition. Phenotypic correlation indicated that oleic acid (C18:1) was negatively correlated to index of atherogenicity (-0.84) and index of thrombogenicity (-0.91), respectively. Statistical analysis revealed that 878T>C SNP was significantly associated with IA (index of atherogenicity, p=0.012) and IT (index of thrombogenicity, p=0.006). There was no association between the regulatory SNPs (-867G>C and -877Gdel) and health indexes. Haplotype analysis detected 4 main haplotype (GdelT; 0.004, GdelC; 0.344, CGT; 0.350 and CGC; 0.261) in Hanwoo. The GdelT haplotype was significant on IA and IT. The effect of GdelT haplotype showed increasing IA and IT values, while GdelC haplotype has a decreasing IA and IT value in Hanwoo. In conclusion, the 878C>T SNP in the SCD gene seems to have an effect on this health index and might be implemented into animal breeding program.

Background : Gentinae Macrophyllae Radix is one of the traditional medicines originated from the roots of multiple plants, Gentiana macrophylla Pall., Gentiana straminea Maxim., Gentiana crassicaulis Duthie ex Burkill and Gentiana dahurica Fisch., in Gentianaceae. Multi-origin traditional medicine usually has adulteration problem based on the morphological similarity and/or misunderstanding the species. Therefore, accurate and reliable identification criteria to ensure drug safety and quality is necessary. Methods and Results : We collected four original species of Gentinae Macrophyllae Radix from plantations and markets in China and Korea. DNA barcoding with four barcoding markers (Internal Transcribed Spacer (ITS), rbcL, trnL intron, trnL-F intergenic sapcer) was performed. Intra-specific variation was observed in ITS nucleotide sequence however, successfully distinct four original species based on the nucleotide discrepancy while trnL intron has no difference. trnL-F intergenic spacer has two transitions(T→C and A→G) sites only in G. crassicaulis and rbcL shows one transition(C→T) site in G. dahurica and G. macrophylla. Phylogenetic relationship analysis of the Gentinae Macrophyllae Radix revealed two major clades – clade I including three groups, G. macrophylla, G. straminea and G. dahurica, and clade II including G. crassicaulis. This aspects was shown more clear with multi-region combined analysis. Conclusion : DNA barcoding will be accurate and powerful criteria for the analysis the origin of Gentinae Macrophyllae Radix. However, single region analysis might be deficient such as trnL intron, rbcL and trnL-F intergenic spacer results in this research. Multi-region combined analysis based on the multiregional DNA barcode markers will be overcome the disadvantage and also increase the precision.

Marked neutrophilia associated with neoplasia is a relatively rare finding and has been considered as a paraneoplastic manifestation. Thyroid cancer seldom presents with paraneoplastic leukocytosis. We report on a case of a 69-year-old man who presented with paraneoplastic leukocytosis seven months after undergoing total thyroidectomy and I-131 therapy for treatment of papillary thyroidcarcinoma. We found neither bone marrow involvement of malignant cells nor hematologic malignancy. Based on elevated levels of serum granulocyte colony-stimulating factor, we concluded that the cause was paraneoplastic leukocytosis. Another interesting point was the anaplastic transformation in the pleural metastatic site. It usually occurs in the intrathyroid or regional lymph node.
