This case was found in Holstein cow suffering from dystocia. The twin calves in uterus were dead and removed by fetotomy. Gross anatomical analysis of thoracopagus siamese calf was carried out. Two normal heads were present on two necks, however, the twins were fused in the thoracic region. There were four forelimbs and an abnormal orientation of ribs. Two separate vertebral columns along the length of the animal ended with two tails. A single pericardium lay on the midline when opening the thorax. However, there were two almost completely hearts within the pericardial sac. Two heart were joined by a common cavernous venous sinuous. There were two sets of lungs. Each twins had a separate esophagus that entered a separated stomach. A large liver was fused and connected into two duodenums. The pelvis, large intestines and urinary tracts were separated. The twins are female and have a full complement of limb.

The objective of this study was to investigate the calf death and analyse the causes of the mortality by based on medical records and autopsy findings during 10 years in a large dairy farm. Total of 1,361 calf born and 146 calf dead during the invested period. Mortality rate was 10.7% and showed the big difference by year-specific mortality from 2.8% (4 calves) to 19.2% (28 calves). The highest rate of mortality was 1 week age (18.5%, 27 calves) and followed by 2 week age (11.6%, 17 calves) and mortality of more old calf tended to be reduced. The death less than 4 weeks and 8 weeks of age of the entire mortality accounted for 41.1% (60/146 calves) and 70.0% (102/146 calves), respectively. Causes of calf death were digestive diseases (53.4%), respiratory diseases (17.1%), musculoskeletal disease (8.2%), and systemic disease (8.2%) in order. Specific causes of calf death was highest in enteritis (43.2%), followed by pneumonia (14.4%), sepsis (8.2%) and fractures (3.4%). Seasonally, most of calf death happened in winter (48.6%) and then fall (21.2%). This results showed that enteritis and pneumonia are the main reason of calf death but other reasons were involved in calf death on the based on autopsy finding. On going research relating factors of calf mortality is needed.

Incidence of mastitis is highest in dairy cows and it is a leader of all diseases and the economic losses, in dairy farms. The objective of this study is to analyse the incidence of clinical mastitis using the lactation number, lactation month and season of calving. In this study, we used 3,779 lactation data and animal health records collected from 1990 to 2006 at the National Institute of Animal Science. Out of 3,779 cows, a total of 1,721 cows were reported with clinical mastitis, which was 46.3%. The frequency of mastitis increased from 36.9% from first lactation to 56.0% by the fifth lactation. As many as 766 cows (46.9%) showed a recurrence of mastitis after 14 days, apart for two or more and chronic mastitis that were recorded for 657 cows (20.3%). This came to a total of 3,010 cases that had clinical mastitis in the herd for sixteen years. The distribution of incidence of clinical mastitis was highest during the first month of lactation at 24.4%, and it reached to 43.4% by the third month. The incidence of mastitis was even higher for cows in first lactation, showing 28.6% in the first month, and 42.9 percent by third month of lactation. Cows calved during the summer and winter months showed higher rate of incidence with 59.9% and 57.9% within 30 days of lactation, respectively. It is urgently needed to establish a preventative management for heifer cows during their expected first lactation and the clinical specific dry-period management strategies that influence the rate of clinical mastitis during the next lactation. The aim of this study is to present information that might be useful to improve clinical mastitis prevention.

The growth rate of piglets will be decreased and the mortality of piglets will be increased in the postpartum sow with mastitis. The aim of this study was to isolate microorganisms from milk samples found in postpartum sows with suckling piglets and to further investigate antimicrobial susceptibility against isolated bacteria. Milk samples were collected from 567 udders of 42 lactating sows and the isolated bacteria was then identified. Isolated bacteria were tested with 12 antimicrobial agents. Bacteria were isolated from 260 milk samples (64.5%). Staphylococcus spp. were the most common microorganisms (74.5%) isolated from sow milk, followed by Streptococcus hyicus (53.9%), Staphylococcus epidermis (11.8%), Staphylococcus aureus (9.8%), and Staphylococcus haemolyticus (53.9%). In the Staphylococcus spp., Streptococcus pneumoniae (5.1%) was isolated as was Streptococcus sanguinis (3.8%) and Streptococcus ovis (2.9%). Results indicated that bacteria isolated from healthy sow milk were mostly susceptible to cephalothin (88.0%), amikacin (85.3%) and cefoxitin (82.4%), but were resistant to streptomycin (10.0%), kanamycin (33.1%) and tetracycline (19.6%).

The present study was undertaken to establish reference values for the composition blood lymphocyte populations and compare forty three Hanwoo neonatal calves (KC) with twenty one Holstein calves (HC) by blood cell count and immunophynotying. The percentages of CD2+, CD4+, CD8+, CD26+, ACT2+, MHC class, MHC class II and WC1+ T cells, B cells were determined by flow cytometry. The number of lymphocyte and monocyte in HC were higher than those of KC. However, the number of neutrophils was higher in HC than KC. The proportions of CD2+, CD4+, CD8+, MHC class, and WC1+ lymphocytes remained relatively stable during the study period, while there was a moderate increase in the relative percentage of CD26+, ACT2+, MHC class II and B cell from birth to approximately 3 weeks of age. Marked differences in the relative proportions of the lymphocyte subpopulations were noted between the individual calves. The present study shows that the T-cell subpopulations are present in peripheral blood of KC at levels comparable with HC, while the MHC class II and B cell population of KC increases significantly with age. The absolute number of WBC in KC was due to the decrease of absolute number of neutrophil rather than the increase of lymphocyte. The results indicated that KC have significantly higher number of neutrophils, and proportion of MHC class II and B cell than HC.

The genus Taraxacum, known by the common name Dandelion, is a medicinal herb in the family Asteraceae. It has been traditionally used as a folk medicine for the treatment or prevention of various diseases due to its anti-inflammatory and anti-oxidative properties. In this study, we attempted to evaluate protective effects of Dandelion related with anti-oxidative activity to Thioacetamide (TAA)-induced liver damage. 36 rats were randomly assigned to six experimental groups:Control, Dandelion water extract (DWE), TAA, TAA&DWE 300, TAA&DWE 600, TAA&DWE 1,200 groups. Rats in DWE and TAA&DWE groups were pretreated with DWE (300, 600 or 1,200 mg/kg BW) by gavage for 7 days. All rats were treated intraperitoneally with TAA (200 mg/kg BW) or normal saline at 12 hours after last oral administration and sacrificed at 12 hours after last treatment. Levels of WBC and Neutrophil count were significantly decresed in TAA&DWE 1,200 group compared with that in TAA group (P <0.05). In TAA&DWE 600 and TAA&DWE 1,200 groups, serum AST, ALT, GGT levels were lower than TAA group (P<0.05). The serum TG level was significantly elevated in TAA&DWE groups compared with those in TAA group. Liver tissues from TAA group showed extensive histopathological changes, characterized by moderate or severe hepatocytes degeneration, inflammatory cell infiltration, and congestion. In the TAA&DWE group, The severity of histopathological lesions were decreased compared to those in the TAA group. The MDA concentration was significantly decreased and GSH content was significantly increased in the TAA&DWE 1,200 group compared to those in the TAA group. GR, CAT and GST activities in the TAA&DWE 1,200 group were significantly increased compared to those in the TAA group.

The incidence of second-grade milk production in 9 dairy farms of South Korea was investigated from May 2011 to March 2012, and the serum composition of cows producing first- and second-grade milk in 14 farms including the 9 farms was analyzed. The incidence rate of second-grade milk production of 402 cows in nine dairy farms located in the central and southwestern regions of Korea was 15.4% with the highest rate being 34.4%. Seasonal morbidity was higher during late winter (February) and early summer (June) with the highest rate observed in February (32.6%) followed by November (33.3%). Second-grade milk was most frequently found within one month postpartum (34.1%) while only 3.5% was found during the first 60∼90 days of lactating period (n=785, 5 herds). The morbidity increased thereafter (P<0.05) with the highest observed between 270∼300 days of lactation (36.1%). The acidity was not significantly different between second-grade (0.159±0.026%) and first-grade milk (0.158±0.027%). Blood serum analysis of 371 cows in the 14 dairy farms indicated that aspartate aminotransferase (AST) level was significantly higher (P<0.001) in cows producing second-grade milk while albumin was significantly lower (P<0.001) than cows producing first-grade milk. Total protein and triglyceride was also significantly low along with glucose, non-esterified fatty acid and blood urea nitrogen in cows producing second-grade milk. Statistical analysis including sensitivity, specificity and positive/negative prediction values showed that lactating cows with high AST, low albumin, total protein and triglyceride levels in the serum tended to produce second-grade milk. It was concluded that serological parameters, especially live functional and metabolic-related serum compositions (AST, albumin, total protein and triglyceride), were significantly influenced in cows producing second-grade milk.

철강산업은 자동차, 조선, 기계, 건설 등을 비롯한 전 산업에 기초소재를 공급하는 산업이다. 제품의 특성상 높은 물류비 비중이 타 산업에 비해 높게 나타나고 있다는 것이 특징이라고 할 수 있다. 특히, 코일 형태의 제품들은 중량물로써 유통 경로 상에서 벌크형태로 취급되고 있어 수송상의 여러 가지 문제점을 가지고 있다. 본 연구에서는 코일의 원활한 컨테이너 운송을 위한 코일 거치장치를 소개하고 거치장치 사용에 따른 여러 비용?편익 평가 항목을 설정하여 사업성 분석을 실시한 결과를 제시하였다. 또한 코일의 컨테이너 운송시 안전성 확보와 거치장치의 반복사용에 따른 물류비 절감방안에 대해 제안하였다. The steel industry has supplied basic materials for the entire industry including the automobile, shipbuilding, machinery and construction materials industry etc. The nature of the products causes higher proportion of logistics costs than in other industries. In particular, steel coils have heavy weight and have been treated as bulk handling on distribution channels. Therefore there are various issues in transporting them. This study analyses the feasibility of equipment to ensure stability during transporting steel coils derived using the cost-benefit analysis. And this paper proposes the method for accomplishing a high level of safety through the use of the equipments during steel coils handling and transport in ISO-containers and cost savings through the reuse of them.
