Backgrounding Beef Cattle Health Programs
Backgrounding is a commercial feeding phase in which newly weaned calves are raised to yearling feeder weight, typically in smaller feedlots. The primary goal is to prepare cattle for smooth transition to high‑energy finishing diets with minimal health issues. This is achieved by feeding a balanced growing ration that promotes efficient weight gain without excessive fattening, relying heavily on roughage-based diets.
Health challenges in the first 45 days depend on factors such as:
- The number of calf sources
- Pre-conditioning or pre-immunization status
- Transport distance and handling stress
1. Buy Quality Calves
A successful backgrounding health program begins with the purchase of healthy, low‑stress calves.
Key purchasing guidelines:
Key purchasing guidelines:
- Prioritize pre‑conditioned or pre‑immunized calves.
- Choose single‑source animals whenever possible.
- When using multi-source groups, fill each pen as a unit and avoid adding new calves later.
- Minimize stress by reducing holding time, transport duration, and excessive handling.
2. Processing Calves on Arrival
Processing should occur as soon as calves arrive and before they are placed in their home pen. Once moved, calves should remain in that pen to reduce stress and exposure.
Castration and dehorning are generally delayed at least three weeks after arrival.
Castration and dehorning are generally delayed at least three weeks after arrival.
Recommended Processing Procedures
- Temperature Check
- Take rectal temperatures on all calves.
- Treat any calf with temperature >40°C using a broad-spectrum antibiotic.
- Identification
- Apply a permanent ID ear tag.
- Vaccinations
- IBR-PI (modified live virus)
- 7- or 8-way Clostridial vaccine + Histophilus somni
- Vitamin A & D injection
- Additional vaccines to consider (consult vet): BVD, BRSV, Pasteurella
- Parasite Control
- Administer systemic parasiticide/insecticide.
- Growth Implant
- Implant with an appropriate growth promotant.
Veterinary consultation is recommended to adjust these guidelines to local disease pressures and management systems.
3. Early Backgrounding Management
After processing and movement to their home pen, the priority is rapid adaptation to feed and water.
Management recommendations:
- Provide high‑roughage rations, primarily good-quality grass hay.
- Introduce small amounts of grain gradually as calves learn to use the bunk.
- Ensure clean, easily accessible water.
- Provide clean, well‑bedded sheds or loafing areas for rest.
- Check calves at least twice daily for appetite, activity, and early signs of illness.
4. Handling Sick Calves
Initial Treatment
- Treat any calf with a rectal temperature >40°C.
- Use long‑acting antibiotics such as:
- Oxytetracycline LA (5 mL/100 lb SQ)
- Micotil (1.5 mL/100 lb SQ)
- Return treated calves to their home pen immediately.
Recurring Illness
- Move relapsed calves to a hospital pen.
- Treat daily for 3–4 days using medications such as:
- Synergistin (5 mL/200 lb IM)
- Trimethoprim/sulfadiazine (3 mL/100 lb IM)
- Return calves to home pen after their final treatment.
Daily pen checks should also monitor for other conditions such as lameness, foot rot, pink-eye, ITEME, polio, digestive issues, and bloat. Veterinary input is crucial for accurate diagnosis and treatment.
5. Working With a Veterinarian
Producers in backgrounding operations should partner closely with their veterinarian to develop a tailored feedlot health and treatment program. Effective veterinary involvement helps:
- Reduce death loss
- Improve treatment outcomes
- Manage drug costs
- Optimize production and maximize profitability
A strong producer–veterinarian partnership supports both animal welfare and operational success.
