For screening the appropriate field diagnostic techniques to failure of passive immunoglobulin transfer(FPT) in Korean-indigenous calves, 258 sera was examined by spectinophotometry for total protein(TP) and globulin(Glo), sodium sulfate precipitation test(SSPT), zinc sulfate turbidity test(ZSTT), and single radial immunodiffusion test(sRID). All calves aged within 6-week old. Morbidity and mortality to various diseases, mainly including enteric and respiratory disorders, were 18.9%(49) and 4.2%(11), respectively. FPT was 27,9%(72/258) when the cutoff point of TP was $4.5g/d{\ell}$ and among them the morbidity and mortality were 27.9% and 6.9%, respectively. FPT was 29.1%(75/258) when the cutoff point of Glo was $2.0g/d{\ell}$ and among them the morbidity and mortality were 29.0% and 6.9%, respectively. FPT was 13.1%(34/258) when the cutoff point of SSPT was 1+ and among them the morbidity and mortality were 67.6% and 23.5%, respectively. FPT was 19.7%(51/258) when the cutoff point of IgG with sRID was $1,000mg/d{\ell}$ and among them the morbidity and mortality were 41.1% and 11.7%, respectively. In addition, mean concentration of IgG with sRID tested was $2,150mg/d{\ell}$ at 3-day old but $1,100mg/d{\ell}$ at 9-days with $1,100mg/d{\ell}$. The results of the study were suggested that SSPT for FPT was the relatively reliable and convinient method for evaluating the immune status of calves(P<0.05).

2011년 경북 영주의 여러 농가에서 이병율과 치사율이 높은 소 바이러스성 설사 바이러스(BVDV)가 발생하였다. 유전자 분석 결과 두 개의 유전자형 BVDV-1b (n = 21)와 BVDV-2a (n = 7)이 확인되었다. 검사결과, 이 지역의 농가에서는 BVDV-1b 유전자형이 가장 많이 검출되었고, 또한 몇 농가에서 BVDV-2a 유전자형도 검출되었다. 이들 농가에서 발생한 BVDV-1b 감염은 BVDV-2 감염과 유사한 중증의 급성 임상증상을 보여 주었다. 이 결과는 한우 송아지에서 급성이면서 치명적인 BVDV-1b 발생을 보고한다.

This study investigated cases of progressively necrotizing limbs in Korean indigenous calves. The recent case (Case 1) involved a 3-month old, male calf in Jeonbuk province that presented a visibly dry form of gangrene affecting joints of the forelimbs and the hind limbs. Radiograph revealed osteoarthritis possibly resulting from pressure of disrupted joint skin, fasciae, deeper underlying musculatures and tendon. Histopathology of affected tissue showed necrotizing; severely thrombosed dilated blood vessels with rechanneling microvasculatures. The lack of substantial infectious inflammatory exudates in the vital organs and the inability to respond to antimicrobial treatment bolstered the notion that the observed thromboembolic and vascular lesion was attributed to possible vasoconstrictive effects of ergot alkaloids. Case 2: A previously encountered similar case in a 4-month old, male calf showing gangrene of hind limbs and posterior ataxia was likewise presented. These two cases were impressed as probable ergotism. Ergotism may be uncommon or underreported in Korea. Future isolation of ergot alkaloids in feeds or in pasture is highly suggested.

소 바이러스성 설사병 바이러스는 전세계 축산업에서 경제적 파급력이 큰 질병이다. 콧물을 이용한 역전사 중합효소연쇄반응을 이용하여 한우송아지에서 소 바이러스성 설사병 바이러스의 발생이 진단 되었다. 가검물을 채취한 21 마리 소 가운데 12마리가 소 바이러스성 설사병 바이러스에 양성반응을 보여 지속감염우로 분류되었다. 이 동물들은 설사와 폐렴 같은 증상을 나타내었다. 지속감염우는 일발적으로 지속감염 송아지에서 발견된다. 5'-UTR을 이용한 염기서열 및 계통발생 분석에서 본 증례는 BDVD-2a에 속했다. 이들 결과는 콧물을 이용하여 지속감염우를 진단할 수 있다는 것과, 한우 송아지에서 BVDV 근절 대책이 필요하다는 것을 말해 주고 있다.

Hypospadias is a rare congenital malformation of the urethra reported in cattle. The urethral lumen of male indigenous Korean calf is open along the ventral aspect of the penis in the perineal region. Renal abscess and renal stone formation causing urinary tact infection has not been reported in hypospadia calves. The objective of this study was investigation for renal abscess and renal stone formation through autopsy. Histopathological examination and laboratory tests were performed. At autopsy, the pustules were formed on the right renal cortex, and the renal medulla abscess were formed on right and left part of the renal pelvis. Histopathological finding, this case was diagnosed as severe acute suppurative and necrotizing pyelonephritis, and severe chronic interstitial nephritis with fibrosis and moderate multifocal acute cystitis with edema. Milky exudate of the kidney has been identified as Actinomyces meyeri using the VITEK-2 system for identification of bacteria, and the stone has been identified as carbonate apatite using FT-IR system for quantification analysis. This case report describe the hypospadias complicated with urinary tract infection due to carbonate apatite stones and Actinomyces meyeri.
