Complex vertebral malformation (CVM) is a recently described monogenic autosomal recessive hereditary defect of Holstein dairy cattle that causes premature birth, aborted fetuses and stillborn calves. Guanine is substituted by thymine (G>T) in the solute carrier family 35 member A3 gene (SLC35A3). A valine is changed to a phenylalanine at position 180 of uridine 5'-diphosphate-N-acetyl-glu...

This investigation was conducted to identify polymorphism of the leptin gene in Holstein cows, Mazandarani native cattle and buffaloes by Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP). The frequencies of A and B alleles were 0.4 and 0. 6 in Holstein cows, 0.56 and 0.44 in Mazandarani native cattle, 0.61 and 0.35 in buffaloes, respectively. The heterozygote genoty...

Intake and annual performance of Limousin × Holstein-Friesian and Simmental × Holstein-Friesian beef suckler cows, and pre-weaning growth of their calves Beef cross dairy heifers remain a significant source of replacement breeding stock for the suckler herd in Ireland. Previous studies at this centre have compared Hereford × Friesian beef suckler dams with Charolais × Friesian and Limousin × Fr...

To analyze the resistance against Theileria sergenti infection in Holstein and Japanese Black cattle under field conditions, clinical, hematological and parasitological findings in these breeds of cattle that were grazed in the same pasture were examined during the grazing period. Holstein cattle showed a higher level of parasitemia than Japanese Black. With the progression of parasitemia, pack...

BACKGROUND In male cattle, rupture of the urinary bladder is usually associated with urethral obstruction by uroliths. Less common causes include urethral compression or stricture. This case report describes the findings in a young Limousion breeding bull with rupture of the urinary bladder because of urethral compression by a haematoma after coccygeal fracture. CASE PRESENTATION The bull had...

Charolais sires can be mated to Montbéliard or Holstein dairy cows to produce crossbred calves sold for meat production. Heritabilities and correlations between traits can differ when they are calculated within Charolais × Montbéliard or within Charolais × Holstein population. Moreover, the genetic correlation between the same trait measured on Charolais × Montbéliard and on Charolais × Holstei...

Introduction: In orthopaedic trauma care, it has long been observed that fractures associated with a peripheral nerve injury lead to impaired fracture healing. This study investigates the relationship between a pure sensory nerve denervation and healing of a standardized femur fracture. Although it is unclear exactly how nerves interact with bone growth and repair, some clinical observations an...

Disorder in the 1D spinless Holstein model. Abstract: We investigate a spinless fermion system on a one dimensional lattice interacting locally with the optical modes of a quantized phonon field: the Holstein model. The system is shown to have a disordered ground state, for small enough coupling, at any density. This is in contrast to the non quantized phonon case, the static Holstein model, wh...

ホルスタイン種の雌育成牛（238 日齡，体重247kg）における左橈尺骨骨幹の非開放性斜骨折と診断した症例について，貫通固定ピンとフルリムキャストを用いた貫通固定ピンキャスト（TPC）法による治療を行った．術中は塩酸キシラジンの静脈内投与（0.2mg/kg）で仰臥位保定後，塩酸メデトミジンの定量持続点滴（20μg/kg/hr）にて鎮静を維持し，2% リドカイン10mℓによる腕神経叢ブロックで疼痛管理した．患肢の牽引と骨把持鉗子により骨折端を合わせて固定し，整形外科用パワードリルを用いて直径4.0mm の貫通固定ピンを，骨折端を挟む遠位および近位側橈骨骨幹にピンを各2 本，近位および遠位骨の骨折端および骨折面を貫通するようにピン3 本をそれぞれ貫通させた．さらにその上からフルリムキャストを巻き，キャスティングテープ表面から露出したピンは約4cm で切断し，即時重合レジンで各ピンの切断部...
