Study of a prevention programme for caprine arthritis-encephalitis
Veterinary Research
|January 1, 1994
Summary
Implementing a caprine viral arthritis-encephalitis prevention program significantly reduced kid contamination. Substitute colostrum feeding, particularly heat-treated, proved more effective than raw colostrum in preventing disease transmission.
Area of Science:
- Veterinary Medicine
- Animal Virology
- Epidemiology
Background:
- Caprine viral arthritis-encephalitis (CAE) poses a significant threat to goat health and production.
- Horizontal transmission is a major route for CAE spread within goat herds.
- Effective prevention strategies are crucial for disease control.
Purpose of the Study:
- To evaluate the efficacy of a prevention program for caprine viral arthritis-encephalitis.
- To assess the impact of substitute colostrum feeding on disease transmission.
- To demonstrate the effectiveness of segregation in preventing horizontal spread.
Main Methods:
- Monitoring of 363 goat herds over a 2-year period (1988-1990).
- Comparison of contamination levels in female kids fed substitute colostrum (heat-treated cow or goat colostrum) versus raw colostrum.
- Analysis of disease transmission based on segregation of animals under prevention measures.
Main Results:
- Overall contamination levels in female kids decreased from 49.5% to 25% during the program.
- Kids fed substitute colostrum showed significantly lower contamination rates (19%) compared to those fed raw colostrum (45%).
- Segregation measures were effective in preventing horizontal transmission.
Conclusions:
- The implemented prevention program was effective in reducing caprine viral arthritis-encephalitis contamination.
- Substitute colostrum, especially heat-treated, is a key intervention for preventing neonatal transmission.
- Herd management practices, including segregation, play a vital role in controlling CAE spread.
