Summary
Bovine embryonic mortality is a frequent reproductive issue in cattle. This review focuses on infectious causes, particularly in Brazil, and discusses control strategies including immunoprophylaxis.
Area of Science:
- Veterinary Medicine
- Animal Reproduction
- Infectious Diseases
Background:
- Embryonic mortality is a significant reproductive disorder in global dairy and beef cattle populations.
- Diagnosing the causes of bovine embryonic mortality is complex due to its multifactorial nature.
- Infectious agents are implicated in up to 50% of bovine embryonic mortalities occurring after 30 days of gestation.
Purpose of the Study:
- To review the primary causes of early and late embryonic mortality in cattle.
- To emphasize infectious etiologies, with a specific focus on those prevalent in Brazilian cattle herds.
- To discuss control and prophylaxis measures, including reproductive and sanitary management, and immunoprophylaxis for common infectious diseases.
Main Methods:
- Literature review of scientific publications on bovine embryonic mortality.
- Analysis of infectious causes and their prevalence in Brazilian cattle.
- Evaluation of control and prophylaxis strategies, including immunoprophylaxis.
Main Results:
- Infectious causes represent a substantial proportion of bovine embryonic mortality, especially after 30 days of conception.
- Specific infectious agents are identified as major contributors to embryonic loss in Brazilian cattle herds.
- Effective control strategies involve integrated reproductive and sanitary management, alongside targeted immunoprophylaxis.
Conclusions:
- Understanding the diverse causes of embryonic mortality is crucial for effective herd management.
- Infectious diseases, particularly those common in Brazil, require focused attention for prevention and control.
- Implementing comprehensive management and immunoprophylaxis programs can mitigate economic losses associated with bovine embryonic mortality.
