[Bovine neonatal pancytopenia in German Holstein calves].

Profiles of blood cell counts were evaluated for 15 calves from three different farms. These calves showed petechia in the mucous membranes and in the skin and prolonged secondary bleeding after puncture. The clinical course of the disease could be observed in eleven calves.

[Vertebral and multiple organ malformations in a black and white German Holstein calf].

A male black and white German Holstein calf showed a congenital, high-graded scoliosis and rotation of the thoracal spinal cord associated with shortening and fusion of multiple vertebral bodies and abnormal bending of the processus spinosus. Furthermore reduced birth weight, partial hypoplasia of the lung, excessive liver segmentation, doubled gall bladder, rectal atresia, horseshoe kidney, and uterine atresia were found. Due to the exclusion of a point mutation in exon 4 of the solute carrier family 35 (UDP-N-acetylglucosamine (UDP-GlcNAc) transporter), member A3 (SLC35A3) gene, complex vertebral malformation (CVM) was ruled out.

Perosomus elumbis in a black and white German Holstein calf.

Perosomus elumbis is a rare congenital anomaly of unknown aetiology characterized by the aplasia of the lumbosacral spinal cord and vertebrae, mostly associated with multiple other malformations of the hind limbs and the urogenital and intestinal tract. This report describes a stillborn female German Holstein calf showing a complete aplasia of the lumbosacrococcygeal portion of the spinal cord and vertebral column. In addition, both hind-limbs exhibited arthrogryposis and the musculature was completely replaced by adipose tissue.

[A case of a congenital high-grade hydrocephalus internus and Dandy-Walker syndrome in a black and white German Holstein calf].

A black and white female German Holstein calf showed a highly deformed cranium. The animal was not able to stand. Further findings were bilateral strabismus divergens and negative pupillary light reflexes.

[Two rare brain malformations in black and white German Holstein calves].

Two black and white female German Holstein calves showed malformations of the cerebrum. The first calf exhibited a cystencephaly and the second calf a meningoencephalocele. The animals originated from two different dairy farms.

[Fissura pelvina with an abdominal hernia and ectopic bladder aperture in a female German Holstein calf].

A three-days-old female black and white German Holstein calf showed a high-graded enlargement of the abdomen.The animal was born at a dairy farm and it was sired by a bull used in artificial insemination.The examination of the animal showed a ventral cleft of the pelvis due to a missing closure of the pelvis symphysis.

[A rare occurrence of dicephalus, scoliosis and complex heart anomalies in a male black and white German Holstein calf].

In a dairy farm in Lower Saxony, a male black and white German Holstein calf showed two partially fused heads, scoliosis of the thoracal vertebral column and a high-graded dyspnoea. The animal was sired by a bull used in artificial insemination. Further affected calves were not known at this farm.
