| Nowadays, an important and interesting alternative in the control of tick-infestation in cattle is to select resistant animals, and identify the respective quantitative trait loci (QTLs) and DNA markers, for posterior use in breeding programs. The number of ticks/animal is characterized as a discrete-counting trait, which could potentially follow Poisson distribution. However, in the case of an excess of zeros, due to the occurrence of several noninfected animals, zero-inflated Poisson and generalized zero-inflated distribution (GZIP) may provide a better description of the data. Thus, the objective here was to compare through simulation, Poisson and ZIP models (simple and generalized) with classical approaches, for QTL mapping with counting phenotypes... |

| A 9-month-old steer was autopsied due to recurrent ruminal tympany. A macroscopic examination found an enlarged caudal mediastinal lymph node, and a section of the lymph node revealed necrosis with marked calcification, similar to tuberculous lymphadenitis. Histopathologically, the lesion consisted of multiple coagulative necrotic foci and fibrosis with macrophage, lymphocyte, eosinophil and multinucleated giant cell infiltration. Non-uniform width hyphae were detected in the necrotic area and within the cytoplasm of the multinucleated giant cells, and they were found to be anti-Rhizopus arrhizus antibody positive in an immunohistochemical examination. Therefore, the steer was diagnosed with necrotic caudal mediastinal lymphadenitis due to zygomycetes... |

| 10 カ月齢のホルスタイン種雌育成牛が急性に斜頸，旋回，後弓反張，意識混濁の症状を呈した．大脳皮質壊死症を疑 い，ビタミンB1 製剤，コルチコステロイドおよび抗生物質による治療を実施したが反応せず，予後不良と判定された． 病理解剖により小脳に直径35. cm 大の腫瘤が確認され，左右側脳室および中脳水道の拡張がみられた．本症例は小脳腫 瘍による周辺部の圧迫および腫瘍の二次的圧迫による脳脊髄液流出障害により発生した内水頭症により，小脳徴候だけ でなく大脳および脳幹症状も出現したものと考えられた．病理組織学的検索の結果，本症例は上衣芽腫と診断された． A 10-month-old female Holstein heifer showed a sudden onset of clinical symptoms of head tilt，circling， increased extensor tone of all legs. and decreased level of consciousness. Cerebrocortical necrosis was suspected， and an administration of vitamin B1， corticosteroids，and anti-biotic was performed without a successful response. At necropsy，a neoplastic mass with a diameter of 3.5 cm in the cerebellum，dilated lateral ventricles on both sides and enlargement of the aqueducts cerebra... |

| 17日齢のホルスタイン種雌子牛が，神経症状を示した. 病畜は頭部を左後方に折り曲げて伏臥姿勢を示し，時折自力で起立したがすぐに倒れ歩行不能であった. 神経学的検査では右の対光反射，威嚇瞬き反射，眼瞼反射， および音響耳介反射が消失していた. ビタミンB1，およびデキサメサゾンの投与により第7病日に歩行可能となったものの左への斜頸・旋回が認められ，神経学的検査所見に改善は認められなかった. 第7病日に病理解剖を行い，肉眼的には橋の断面右側に直径1cm大の膿瘍を認め，嫌気培養にてFusobacterium necrophorumが検出された. 左側への斜頸，聴覚の消失等の脳神経疾状は，橋の右側の膿瘍により内耳神経等の脳神経核が圧迫された結果出現した聴覚障害，平衡障害のためと考えられた. A 17-day-0ld female Holstein calf exhibited the following neurological symptoms: the calf bent its neck to the left，turning its face backward and could stand alone，but would fall within a short time. Neurological examination further revealed losses of pupillary light reflex， menace response，palpebral reflex，and hearing on the right side. After administration of dexamethasone and vitamin B1，the calf was able to walk... |
