| 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... |

| 道東の2農場にて出生したホルスタイン乳用子牛計36頭を用い，牽引の程度が子牛の活力，血液ガス，血清免疫グロブリン （Ig） G濃度に及ぼす影響を調査した．牽引状況を数値化するために，牽引強度と牽引時間をそれぞれ4段階 （0~3） で評価しスコア化したものを掛け合わせて牽引スコア （0~9） とし，牽引スコアの値によって子牛を自然分娩群（0），軽度牽引群（1），中程度牽引群（2~3）および重度牽引群（4~9）の4群に分類した．活力の評価には，ヒトのApgarスコアを子牛用に改変したものを用い，出生3分後に評価した．子牛の採血は頸静脈より行った．結果，Apgarスコアは自然分娩群と比較し軽度牽引群，重度牽引群で有意に低下した （それぞれp<0.05）．出生5分後の静脈血水素イオン指数（ pH） は，中程度から重度の牽引群において自然分娩群から軽度牽引群までと比較して有意に低下し （p<0.01），二酸化炭素分圧 （pCO2） は有意に増加した （p<0.005） が，重炭酸イオン濃度（ HCO3−） はどの時点においても群間に差は認めなかった （p>0.75）．また，出生24時間後の血清IgG濃度は自然分娩群と牽引群の間には有意な差は認めなかったが，牽引群内で重度になるにつれ低下し，軽度・重度牽引群間で有意差が認められた （p<0.05）．さらに，出生5分後の静脈血pHと24時間後血清IgG濃度との間に有意な相関が認められた... |

| 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... |

| 体表リンパ節の腫脹, 末梢血中における異型リンパ球出現を伴うリンパ球数の著増などの典型的な牛白血病症状を示していなかったことから, それぞれアミロイドーシス, 胸膜炎, 心疾患が疑われた3頭のホルスタイン種乳雌牛を病理解剖したところ, いずれも牛白血病と診断された. 血液検査および身体検査において著変が観察されない場合でも, 難診断時には鑑別診断リストに牛白血病を加えるべきであると考えられた. |

| 19歳齢のペルシュロン種繁殖雌馬に血尿が認められた。血尿は止血剤および抗生剤投与によっては改善され なかった。患畜は次第に元気食欲の低下、削痩、貧血を呈し、高度蛋白尿および胸前部冷性浮腫が発現した。 直腸検査により人頭大に腫大した左腎を触知し、腎臓腫瘍を疑った。病理解剖の結果、左腎は27X18Xl0cmに 腫大し、血液に富む巨大な腫瘤形成(13X8X8cm)を認めた。左腎門リンパ節は腫大し、また右腎臓、左右 副腎、肝臓および肺では大小の白色腫瘤を認めた。病理組織学的検査によりこれらの腫瘍はいずれも浸潤性に 増殖する上皮性腫瘍組織であったことから、本症例は腎細胞癌が他の複数の臓器に転移したものと考察した。 |
