Introduction
A comprehensive description is presented of four novel cases ofamorphus globosus (ag) foetuses originating from multiple pregnancies of Polish Holstein cows.

Material and Methods
Four amorphic foetuses were delivered by three cows. Tissue samples were collected during autopsy, embedded in paraffin, sectioned, and stained with haematoxylin and eosin. Genomic DNA was isolated from tissue samples of abnormal foetuses and from blood leukocytes of their healthy siblings. PCR reactions were used to reveal the presence of Y-linked genes (SRY and AMELY) and an X-linked gene (AMELX).

Results
All foetuses were classified to the groupholoacardius amorphous (anideus). Molecular analysis clearly showed that at 17 microsatellite loci, the studied amorphous foetuses had identical genotypes to the viable co-twins.

Conclusion
Foetuses had monozygotic origin. Histological analysis showed a low level of development of tissues of meso- and ectodermal origin, as well as features of degrading patterns.
