Summary
A rare case of extreme multiple pregnancy in a Brown Swiss cow resulted in the cow
Area of Science:
- Veterinary Pathology
- Reproductive Biology in Cattle
Background:
- Multiple pregnancies are uncommon in cattle, with most cases involving twins.
- Pregnancy complications can arise from uterine distension and organ compression.
Observation:
- A 5-year-old pregnant Brown Swiss cow presented with recumbency and subsequent death.
- Necropsy revealed a sextuple pregnancy (six fetuses) alongside an amorphous globosus.
- Internal organ displacement and lung compression were noted, alongside a diagnosis of fatty liver due to metabolic disturbances.
Findings:
- The extreme multiple pregnancy (six fetuses) was the primary cause of the cow's demise.
- Concurrent fatty liver indicated significant metabolic stress.
- The amorphous globosus is a rare teratoma, often associated with multiple pregnancies.
Implications:
- This case highlights the risks associated with super-ovulation or genetic predispositions for multiple births in cattle.
- Understanding the causes of extreme multiple pregnancies is crucial for reproductive management and preventing mortality.
- Further research into genetic factors and hormonal treatments influencing bovine superfecundity is warranted.
