This paper reviews complications of bovine gestation, including uterine torsion, vaginal prolapse, fetal issues like mummification, and hydropic conditions such as hydrallantois and hydramnios.

Area of Science:

  • Veterinary Medicine
  • Reproductive Biology
  • Teratology

Background:

  • Gestation in cows can be complicated by noninfectious conditions, including uterine torsion and vaginal prolapse.
  • Fetal and placental issues, such as mummification, maceration, and hydropic conditions, also impact pregnancy outcomes.
  • Emerging issues like abnormal offspring syndrome are linked to assisted reproductive technologies.

Purpose of the Study:

  • To review the predisposition, clinical signs, diagnosis, and management of uterine torsion in cows.
  • To discuss the pathogenesis, clinical presentation, treatment, and prognosis of vaginal prolapse during late gestation in cattle.
  • To compare and contrast fetal and placental complications, including fetal mummification, maceration, and hydropic conditions (hydrallantois and hydramnios).

Main Methods:

Related Experiment Videos

  • Literature review of uterine torsion and vaginal prolapse in late-gestation cows.
  • Discussion of fetal complications: mummification, maceration.
  • Comparative analysis of hydropic conditions: hydrallantois versus hydramnios, and mention of abnormal offspring syndrome and teratology resources.

Main Results:

  • Uterine torsion and vaginal prolapse are significant accidents of gestation in cows.
  • Hydrallantois, a placental issue, is significantly more common than hydramnios, which stems from fetal anomalies.
  • Abnormal offspring syndrome is a noted complication associated with in vitro fertilization (IVF) and somatic cell nuclear transfer (SCNT) embryo transfer.

Conclusions:

  • Comprehensive understanding of these diverse gestational complications is crucial for bovine reproductive health.
  • Distinguishing between placental and fetal origins of hydropic conditions aids in prognosis and management.
  • Awareness of teratological conditions and assisted reproductive technology-related syndromes is important for modern veterinary practice.
