| Computed tomography (CT) was used for diagnosis of brain abscess in a 6-month-old, Japanese black calf presented with neurological dysfunction, compulsive circling and vision disturbance. CT images showed asymmetric lateral ventricles, and presence of intra-cranial multiple low absorption lesions surrounded by capsule suggestive of abscess in the right cerebral hemisphere. Postmortem examination revealed marked swelling of right cerebral hemisphere and olfactory bulb. Multilocular large abscess containing creamy pus was found to occupy most area of periventricular and lateral ventricle. Fusobacterium necrophrum was isolated from the abscess contents as the causative agent. These results demonstrate that CT is useful tool for tentative diagnosis of bovine... |

| 1日齢における血中免疫グロブリンG（IgG）濃度が基準値未満の場合に受動免疫移行不全（FPT）と診断されるが，子牛が肥育牧場や育成牧場に導入される1週齢前後のFPT基準値は報告されていない. 本研究は, 血清IgGおよび総タンパク質（TP）濃度の経時的変化を調べ, 7日齢の検査値を用いたFPT診断精度について検証した. ホルスタイン種（HS）43頭, 黒毛和種（JB）34頭を用いた. 1日齢と7日齢に採血を行い, 血清IgG（mg/mℓ）およびTP濃度（g/dℓ）を測定した. 1日齢と7日齢において, IgGとTPの間に強い正の相関関係が認められた. 1日齢のIgGとTPの散布図において, 近似曲線の一次方程式にFPT基準値（HS-IgG: 10.0, JB-IgG: 20.0）を代入して求めたTP濃度（HS-TP: 4.6, JB-TP: 5.3）を1日齢のFPT基準値とした. HS-IgG, HS-TPおよびJB-IgGは, 1日齢〜7日齢にかけて有意に減少した. 1日齢〜7日齢の平均変化率は, HS-IgG: 71.7%, HS-TP: 92.2%, JB-IgG: 73.8%, JB-TP: 95.4%であった. 1日齢のFPT基準値に平均変化率を乗じて7日齢のFPT基準値とした（HS-IgG: 7.2, HS-TP: 4.2, JB-IgG: 14.8, JB-TP: 5.1）. 7日齢の血液検査において, FPT基準値未満であった場合を検査陽性とし, FPTの診断精度について検証した. HS-IgGの陽性的中率（PPV）は78.6%, 陰性的中率（NPV）は93.3%, HS-TPのPPVは76.5%, NPVは100.0%であった. JB-IgGのPPVは100.0%, NPVは80.0%,... |

| The present study evaluated the effect of hemoplasmosis on cattle productivity. Prevalence of bovine hemoplasma was examined by polymerase chain reaction (PCR) using whole blood samples collected from 93 breeding cows and their 71 calves in Hokkaido, Japan. Monthly milk production records and other clinical data were compared between Mycoplasma wenyonii (Mw)-infected, “Candidatus Mycoplasma haemobos” (CMh)-infected, co-infected and PCR-negative groups. Blood chemical parameters were obtained from the 93 cows and 64 calves. PCR results showed that 89.2% (83/93) of cows and 14.1% (10/71) of calves were positive for bovine hemoplasma. Based on productivity data obtained from the 93 cows, Mw-infected, CMh-infected and co-infected cows had significantly lower... |

| The aim of our study was to investigate the effects of suckling on reproductive performance and metabolic status of obese (mean body condition score of more than 4.0 on a scale of 1-5) maternal Japanese Black cows during early postpartum period. We used 7 postpartum Japanese Black cattle. Four cows were suckled ad libitum (suckled) until completion of their first artificial insemination (AI), while 3 cows were not suckled at all because they were separated from their calves immediately after parturition (non-suckled). Body weight and plasma concentrations of metabolites and hormones were measured from wk 1 to 9 postpartum. Ovarian activity was detected using plasma progesterone concentration, and all cows received their first AI after application of the... |

| Heavy draft mares potentially have a higher risk of suffering from postpartum fever (PF) than light breed mares. The purpose of this study was to compare hematological and biochemical features between clinically healthy mares (n=40) and PF-affected mares (n=16). Mares were classified as having PF when their rectal temperature rose to >38.5°C within 96 hr of foaling. The numbers of leukocytes, lymphocytes, and neutrophils and the serum magnesium level were significantly lower in PF-affected mares. The serum SAA and NEFA levels were significantly higher in PF-affected mares. Strong inflammation responses, fat mobilization associated with negative energy balance and possibly endotoxin participate in hematological and biochemical features of PF in heavy... |

| To establish a method to predict postpartum diseases using prepartum back fat thickness (BFT), the peripartum BFTs of 54 healthy multiparous cows before calving, which were diagnosed with postpartum displacement of the abomasum (DA), clinical ketosis or subclinical ketosis were compared with those of healthy cows from 8 weeks before the expected calving date to 8 weeks after calving. The peripartum BFTs of the cows with DA or clinical ketosis were significantly higher than those of healthy cows. The peripartum BFTs of the cows with subclinical ketosis were not significantly higher than those of the healthy cows. |

| ベントナイトのセシウム体内移行抑制効果について調べた。実験には，ホルスタイン種子牛6頭を使用し，28日の実験期間中，全頭に安定同位体の塩化セシウム（3.0mg/kg/day）を人工乳に溶解し，投与した。塩化セシウムに加えベントナイト0.5w/v％を人工乳に懸濁した投与群（n=3）と塩化セシウムのみの対照群（n=3）の2群を設定した。実験開始0，1，2，3，7，14，21および28日目に採血，28日目に骨格筋，心臓，肝臓，腎臓および糞便を採材し，ICP-MS （inductively coupled plasma mass spectrometry） によるセシウム濃度を測定した。臓器中のセシウム濃度からベントナイトの効果は明らかではなかったが，血球中セシウム濃度平均値は投与後14日まで投与群が対照群よりも低値を示した。このことから，ベントナイトによるセシウム体内移行抑制効果の可能性が示唆された。 |

| The aim of this study was to clarify the relationship between circulating oxytocin (OT) and PGF2α metabolite (PGFM) in mares at the third stage of labor and placental expulsion time in order to investigate a cause of retained placenta of which the incidence increase in a heavy draft mare. Blood was sampled every 5 min from foaling to expulsion of the placenta in 18 heavy draft mares to evaluate circulating OT and PGFM. The relationships between OT and PGFM concentration and recorded placental expulsion times were investigated. The results were as follows (1) The highest level of OT concentration was observed close to foaling in 15 mares. (2) The OT concentrations close to foaling were variable with a large difference from the lowest concentration, 22.1... |

| The aim of this study was to investigate the relationship between the first ovulation within 3 weeks postpartum and subsequent ovarian cycles and fertility in high producing dairy cattle in Hokkaido, Japan. In Experiment 1, 110 cows (44 primiparous and 66 multiparous) were used to determine the effects of the first ovulation within 3 weeks postpartum on subsequent ovarian cycles. Milk samples were collected twice weekly from 7 to 100 days postpartum. The first ovulation was identified by an increase in milk progesterone (P4) to more than 1 ng/ml within 3 weeks postpartum. The numbers of cows showing ovulation and anovulation within 3 weeks postpartum were 31 (70.5%) and 13 (29.5%) in the primiparous cows and 35 (53.0%) and 31 (47.0%) in the multiparous... |

| The aim of this study was to clarify the relationship between the placental retention time (PRT) and the reproductive performance following mating at the foal heat in Thoroughbreds. For this purpose, we interviewed 292 farmers over a period of 3 years with questionnaires evaluating foaling, expulsion of placenta and reproductive performance at the foal heat in 1,432 mares. The obtained data were later compared with a previous study of heavy draft mares. The average of the PRT of the 1,432 Thoroughbred mares was 58 ± 88 min (mean ± SD). The mean PRT of Thoroughbreds was significantly shorter than that of the148 min of heavy draft mares. The incidences of retained placenta (RP) occurring in the Thoroughbred mares were 5.2 and 4.0%, for over 3 and 4 hr after... |

| 牛臨床におけるComputed Radiography (CR) の有用性を確立するため，管球-カセッテ間距離およびImaging Plate (IP) の読み取り時間が画質に与える影響について検討した.管球-カセッテ間距離は画質の視覚的スコア(粒状性，鮮鋭性)に影響しなかった. IPの読み取り時間は画質の鮮鋭性と相関しなかったが，粒状性と相関が認められた.しかし読み取り時聞が12時間以内の場合には問題にならない程度であると考えられた.管球-力セッテ間距離を再現よく保つことが難しく， IP読み取り時間のばらつきが想定される牛の臨床画像診断においてCRは有用なX線撮影システムであると考えられた. The purpose of this study was to investigate the effect of X-ray tube-cassette distance and image scanning time on image quality to establish the benefit of Computed Radiography (CR) in bovine clinical practice. The tube-cassette distance had no effect on the visual evaluation score (graininess and sharpness). The image scanning time correlated with graininess but not sharpness. From these results，it was concluded that accidental variations in the tube-cassette... |
