The Threat of Clostridial Diseases in Livestock
Clostridial bacteria, found in soil and animal intestines, pose a significant risk to cattle and sheep. These bacteria can produce potent toxins leading to severe, often fatal, diseases. Diseases like blackleg, malignant edema, black disease, and enterotoxemia can strike quickly, causing substantial economic losses. Preventative vaccination is key to managing these sudden-onset, high-mortality diseases.
What is UltraChoice 8?
UltraChoice 8 is an 8-way killed bacterin-toxoid vaccine from Zoetis. It is formulated to protect healthy cattle and sheep against eight clostridial diseases caused by Clostridium chauvoei, Cl. septicum, Cl. novyi, Cl. sordellii, Cl. haemolyticum, and Cl. perfringens Types B, C, and D. The vaccine includes a Stimugen adjuvant to enhance immune response and reduce injection-site reactions.
Diseases Prevented by UltraChoice 8
UltraChoice 8 offers protection against several critical clostridial diseases:
- Blackleg: Caused by Cl. chauvoei.
- Malignant Edema: Caused by Cl. septicum.
- Black Disease: Caused by Cl. novyi.
- Gas-Gangrene: Caused by Cl. sordellii.
- Bacillary Hemoglobinuria (Red Water): Caused by Cl. haemolyticum.
- Enterotoxemia & Enteritis: Caused by Cl. perfringens Types B, C, and D.
Administration and Vaccination Schedule
UltraChoice 8 should be administered subcutaneously to healthy animals. A primary vaccination course is required, followed by revaccination as recommended by a veterinarian. In areas with high risk of Cl. haemolyticum, more frequent administration may be necessary. A withdrawal period is required before slaughter. Consult the product label and your veterinarian for the specific volume and schedule appropriate for your animals.
Comparison: 7-Way vs. 8-Way Vaccines
Both 7-way and 8-way clostridial vaccines offer protection against multiple Clostridium strains. The key difference is that 8-way vaccines typically include protection against Cl. haemolyticum (Red Water), which is often not present in 7-way versions {Link: Old Mill Country Store https://oldmillcs.com/ultrachoice-8-cattle-sheep-vaccine}. For a detailed comparison, see the table below based on general vaccine types:
| Feature | UltraChoice 7 (General Type) | UltraChoice 8 |
|---|---|---|
| Core Protection | Cl. chauvoei, septicum, novyi, sordellii, perfringens Types C & D | Cl. chauvoei, septicum, novyi, sordellii, perfringens Types C & D |
| Added Protection | Varies (e.g., Tetanus in some 7-way vaccines) | Cl. haemolyticum (Red Water) |
| Best For | Regions without significant Red Water risk. | Regions where Cl. haemolyticum is a concern or broader protection is desired. |
Safety and Side Effects
UltraChoice 8 is generally safe, but temporary injection site swelling can occur. Rare severe allergic reactions requiring veterinary care are possible. A temporary decrease in milk production has been noted in dairy cattle. Safety in pregnant animals has not been evaluated.
Conclusion
UltraChoice 8 is a vital vaccine for protecting cattle and sheep against eight significant clostridial diseases. Its comprehensive coverage supports livestock health and protects producers' investments. Always consult with a veterinarian to develop the most suitable vaccination strategy for your specific herd or flock needs {Link: Old Mill Country Store https://oldmillcs.com/ultrachoice-8-cattle-sheep-vaccine}.
