지중룡,Md. Rafiqul Alam,나종삼,김남수 한국임상수의학회 2011 한국임상수의학회지 Vol.28 No.2

The health status of three groups of Hanwoo steers (n = 157) aged 2-3 years, raised at three different altitudes (600 m, n = 50; 200-400 m, n = 58; plane land, n = 49) and environment with more or less similar management have been evaluated through hematological, biochemical and globulin examinations in order to determine the optimum environment suitable for raising cattle while at the same time minimizing the risk of disease. Five mL of blood samples from each animal were collected by jugular veinipuncture and 2 mL was transferred to a tube containing EDTA for complete blood count (CBC) and 3 mL in lithium heparin for chemistry screening (CS) and immunoassay. Among the CBC parameters a significantly higher white blood cell count (tWBC), total red blood cell count (tRBC), hemoglobin (Hb) and packed cell volume (PCV) were noticed in the high altitude groups, whereas those were lower in the plane land group. In the CS parameters higher levels of aspartate aminotransferase (AST), creatinine, lactate dehydrogenase (LDH) and total bilirubin (TBL) were found in the plane land group, whereas those were lower in the high altitude groups. The total protein (significantly) and globulins were higher in the 600 m group. The results of this study revealed that the overall health status of the Hanwoo cattle based on the hemato-biochemical indices was superior in the highest altitude and inferior in the plane land group but all the parameters were within the reference range in all the groups. Therefore, for recommendation of a suitable environment at an appropriate altitude for raising cattle there need to be further studied along with the hemato-biochemical parameters; considering, breeding, feeding, management, marketing, waste disposal and other factors.

지중룡,최영민,송동용,최호성,나종삼,심관섭,Ji, Joong-Ryong,Choi, Young-Min,Song, Dong-Yong,Choe, Ho-Sung,Na, Chong-Sam,Shim, Kwan-Seob 한국축산식품학회 2011 한국축산식품학회지 Vol.31 No.2

본 연구는 페퍼민트 급여가 재래흑돼지의 육질특성과 근육내 지방산 조성 및 콜레스테롤 함량에 어떠한 영향을 미치는지 분석하기 위해 실시하였다. 이를 위해 페퍼민트 분말을 평균체중이 $77{\pm}5$ kg일 때부터 출하까지 0.2%(T1) 또는 0.4%(T2)를 50일간 급여하였으며, 도축 후 등심근을 채취하여 다양한 품질특성을 분석하였다. 일반성분은 처리구간에 유의적인 차이가 나타나지 않았으나, T2처리구에서 조지방 함량이 대조구보다 감소하는 경향이었다. 사후 45분 pH는 처리구간에 유의적인 차이가 없었지만, 24시 pH에서 대조구보다 유의적으로 T2처리구가 높게 나타났다(p<0.05). 육색에 있어서 명도와 황색도는 T2가 대조구보다 유의적으로 낮게 나타났다(p<0.05). 연도와 보수력 역시 처리구간에 차이가 없는 것으로 나타났다. 페퍼민트 첨가는 지방산 조성과 콜레스테롤 함량에 영향을 미치지 못하였으나, T1은 대조구보다 포화지방산이 감소하고 불포화지방산이 증가하는 경향이었다. 또한 콜레스테롤 감소지수는 T1이 대조구보다 유의적으로 높게 나타났다(p<0.05). 이상의 결과를 종합하면 페퍼민트 첨가 사료는 돈육질에 큰 영향을 미치지는 않지만, 지방산 및 콜레스테롤의 건강기능적인 측면에서 긍정적인 영향을 미칠 것으로 판단되며, 보다 심도 있는 추가 연구가 필요한 것으로 사료된다. This study was conducted to investigate the effect of peppermint powder on meat quality and fatty acid composition in finishing Korean native black pigs. Ninety pigs were randomly allocated to three dietary treatments and fed peppermint powder at 0 (C), 0.2 (T1), and 0.4% (T2) in the basal diet, respectively for 50 d. The proximate composition of Longissimus dorsi muscle was not significantly different among the treatments; however, the fat content in T2 tended to be lower than the control. No difference in $pH_{45min}$ was observed, whereas $pH_{24h}$ was higher in T2 than the control (p<0.01). T2 showed the lowest lightness (p<0.01) and yellowness values (p<0.05), but shear force and drip loss were no different among the treatments. Individual fatty acid and cholesterol compositions did not differ among the treatments; however, T1 showed a decreasing trend for saturated fatty acid content and an increasing trend for unsaturated fatty acid content. The hypocholesterolemic index was significantly higher in T1 than in the control (p<0.05). These results suggest that dietary peppermint could positively affect fatty acid and cholesterol levels without changing meat quality in finishing Korean native black pigs.

Many animal models of osteoarthritis (OA) have been developed, aimed at understanding the long-term progression of OA and difficulty of identifying patients in the initial stage of the disease. In canines, coxofemoral luxation and hip dysplasia are common orthopedic ailments related to OA in the hip joint. Transecting the ligament of the head of the femur (LHF) aids in diagnosis of coxofemoral joint OA. Presently, mobility of this joint was increased by transected LHF in 10 mature, 2-3-year-old (average 2.57 ± 0.20 years), healthy male beagles. The animals were normally gaited 1-week post-operatively. During the experimental period, examinations including X-ray, complete blood count and serum chemistry were unremarkable. Proteomic examination revealed protein alterations in synovial fluid,with significant increases in Vitamin D-binding protein precursor (ANOVA, p < 0.004) and Kinogen-1 (ANOVA,p < 0.039). Both proteins correlated with arthritis.

고재진,김세훈,지중룡,김남수,심관섭 한국임상수의학회 2010 한국임상수의학회지 Vol.27 No.6

To investigate patterns and severity of hunting-related emergency traumatic injuries in wild boar hunting dogs. One hundred wild boar hunting dogs with emergency traumatic injuries sustained during wild boar hunting as a result of wild boar attack and accidental shooting of ensnarement in a trap. The retrospective study involved 100dogs brought to CAMC for treatment of emergency traumatic injury sustained during wild boar hunting in Jeon-buk province from August 2007 to April 2008. Medical information obtained from the medical records included signalment;cause of injury; number, location and severity of injuries; and mortality. The 100 patients displayed 136 injuries (single injury in 71 dogs and multiple injuries in 29 dogs). Causes of the emergency traumatic injuries were wild boar attack (n = 92), accidental shooting (n = 7), and entrapment (n = 1). The thoracic area was the most common site of injury. The most common injury severity score (ISS) was code 2. The mortality rate was 9%, and all deaths involved thoracic injury. Emergency traumatic injuries sustained during wild boar hunting are most commonly thoracic injuries caused by prey attack. The nature of the injuries can differ from those typically encountered by small animal veterinarians.

This study was carried out to remove cholesterol from liquid egg yolk by using β-cyclodextrin(β-CD) which formed insoluble complex by binding with cholesterol existed in oil-water interface of egg yolk. The conditions of treatment varied with the centrifugal force, mixing temperature, mixing time, distilled ratio and β-CD : cholesterol molar ratio, and the removal efficiency of cholesterol of each treatment was measured. The optimal conditions of centrifugal force, mixing temperature and mixing time to remove β-CD. cholesterol complex were 2,000 g, 35℃ and 15 min, respectively. The ratio of egg yolk to distilled water was 1 : 3 with the most cholesterol removal and with the highest solid content remained. When the molar ratios of β-CD to the egg yolk cholesterol were 3: 1, 5: 1 and 6: 1, the efficiencies of cholesterol removal were 75.0, 88.9 and 95.9%, respectively, and the contents of remnant solid were 68.2, 64.6 and 56.9%, respectively. As the amount of added β-CD increased, cholesterol removal efficiency was increased but valuable nutrients of egg yolk also decreased. Therefore, it was concluded that the molar ratio of 3 : 1 -5 : 1 for β-CD : cholesterol was most effective in removing cholesterol from egg yolk, considering the amount of valuable components remained.

Two day-old male and 1 month-old female Hanwoo calves presented to Chonbuk Animal Medical Center in Chonbuk National University. Two calves were stepped by mother cow and had right (2 day-old male) and left (1 month-old female) forelimb lameness. The male calf was diagnosed as right radius-ulnar fracture through physical and radiographic examination. The other female calf was diagnosed as left third and fourth metacarpal bone fracture by the same examinations as male calf. Acrylic frame external fixator was used to reduce the fractures. Arcrylic frame external fixator in two calves lasted for 5~6 weeks. After removing the acrylic frame external fixator, radiographic evaluation and physical examination were performed. Fractured radius-ulnar and metacarpal bones were unionized and the calves were able to stand and bear weight. In these two calves, application of acrylic frame external fixator in calf fracture was effective. Acrylic frame external fixator should be considered for the repair of radius-ulnar and metacarpal bone fracture in calf.

The effects of Lactobacillus plantarum, which produce bacteriocin, isolated from fermented foods (NFS #6-6, fermented sausage: S #3, kajami sikhae) on the physico-chemical properties of fermented sausages were compared with commercial starter culture, SL during storage at 24℃ and 35℃. Sausages treated with NFS #6-6 and S #3 had higher a value than SL at 24℃. Saturated fatty acid (SFA) were increased but unsaturated fatty acid (USFA) were decreased after 4 weeks storage and that ratio were high as the storage temperature were increased, regardless of treated starters. Free amino acid contents were decreased but glutamic acid, lysine and aspartic acid were detected in large amount as compared with other free amino acids after 4 weeks storage, regardless of storage temperatures and treated starters. TBA values were 0.24∼0.27 ㎎/㎏ at 24℃ and 0.49∼0.52 ㎎/㎏ at 35℃ after 4 weeks storage and did not show any difference among samples.
