Fall Herd Health Check: Vaccinations, Deworming, and Body Condition Scoring
As the seasons shift from the heat of summer to the cool crisp days of fall, ranchers know it’s not just pastures that need attention—livestock health must also be at the top of the checklist. Fall is a crucial window to prepare cattle, sheep, and goats for the challenges of winter. By focusing on vaccinations, deworming, and body condition scoring, producers can set their herds up for a healthier, more productive cold season.
Why Fall is the Right Time for a Herd Health Check
Fall herd management is about prevention. Winter can place significant stress on animals due to cold weather, limited forage quality, and increased energy demands for maintenance and survival. If animals enter the season undernourished or carrying heavy parasite loads, they’ll struggle to maintain body condition and productivity.
Performing a herd health check now ensures:
- Healthier overwintering with fewer disease outbreaks.
- Better reproductive success in the coming breeding season.
- Improved weight gain and feed efficiency, saving costs through winter feeding.
1. Vaccinations: Building Immunity Before Stress
Vaccination programs should always be tailored to your herd, region, and management system, but fall is a strategic time to boost immunity. Cooler weather and upcoming close confinement increase disease risks, so protection matters.
Key Vaccinations to Consider:
- Respiratory Diseases (BRD Complex) – Vaccines for IBR, BVD, PI3, and BRSV help reduce losses in cattle, especially calves.
- Clostridial Diseases – “Blackleg” vaccines are essential for young cattle and small ruminants.
- Leptospirosis and Vibriosis – Reproductive disease prevention for herds headed into breeding.
- Rabies – In areas where wildlife poses a risk.
- Sheep and Goats – CD&T (Clostridium perfringens types C & D and tetanus) is the gold standard.
💡 Pro Tip: Work closely with your veterinarian to design a fall vaccination schedule that aligns with your herd’s unique risks and timing.
2. Deworming: Controlling Parasites Before Winter
Internal parasites can sap nutrition and compromise immune systems. In fall, when forage is declining, deworming ensures animals go into winter with a clean slate.
Best Practices for Deworming:
- Strategic Timing – Treat after the first hard frost in many regions, when parasite activity naturally slows.
- Rotation of Products – Avoid resistance by rotating between classes of dewormers (e.g., ivermectins, benzimidazoles, moxidectins).
- Fecal Testing – Use fecal egg counts to determine parasite loads and avoid unnecessary treatments.
- Pasture Management – Resting fields in rotation can reduce re-infestation.
For sheep and goats, resistance to dewormers is a serious concern. Targeted selective treatment—treating only animals showing signs of parasite stress—can help slow resistance.
3. Body Condition Scoring: The Most Overlooked Tool
Body condition scoring (BCS) is one of the most cost-effective ways to evaluate herd health. Going into winter, animals should have enough fat reserves to handle the higher energy demands of cold weather and pregnancy.
Scoring Guidelines:
- Cattle: Scored on a 1–9 scale. Ideal fall BCS is 5–6 for cows, and 6 for heifers before breeding.
- Sheep & Goats: Scored on a 1–5 scale. A score of 3–3.5 is recommended going into winter.
Why BCS Matters:
- Thin animals lose condition faster, are more vulnerable to disease, and may fail to breed back in spring.
- Over-conditioned animals can face metabolic disorders and calving/lambing difficulties.
Regular hands-on checks—feeling along the ribs, backbone, and hips—are more reliable than visual assessment, especially with thick winter coats.
4. Additional Fall Health Considerations
Beyond the “big three” of vaccinations, deworming, and BCS, ranchers should also check:
- Hoof Health – Trim overgrown hooves to prevent lameness in wet, icy conditions.
- Mineral Access – Ensure free-choice mineral supplementation continues through fall and winter.
- Water Supply – Prepare troughs and waterers against freezing temperatures.
- Breeding Animals – Assess bulls and rams for fertility if breeding season is upcoming.
5. Working With Your Veterinarian
No two herds—or regions—are the same. A herd health plan designed with veterinary input helps you stay ahead of preventable problems. Many veterinarians offer fall herd health clinics, which can streamline processing, recordkeeping, and overall efficiency.
Final Thoughts
Fall isn’t just a transition season—it’s the time when smart ranchers invest in their herd’s health for the months ahead. By making vaccinations, deworming, and body condition scoring part of your fall routine, you’re not just reacting to problems—you’re preventing them.
A healthy herd going into winter means fewer surprises, better productivity, and stronger animals come spring.
