November Dairy Farming Tips for Waikato Farmers – Cow, Calf & Yearling Care
November 2025

🐄 COWS

  • Bloat Risk
    Clover-rich silage aftermath continues to pose a bloat risk. Use Rumenox® or Rumensin® capsules and avoid grazing hungry cows on lush pasture. Provide fibre to reduce risk.
  • Heat Detection
    Keep up with heat detection—those final weeks matter. Short gestation semen can help tighten your calving spread. Monitor cows for heat stress, which can reduce conception rates.
  • Lameness
    Lift and treat every lame cow early. Use pain relief and blocks. Staff training is available—contact your vet to arrange a session.
  • Mastitis & BMSCC
    Submit milk samples for culture to guide treatment. Target cows with SCC >500,000. Review milking technique and equipment—liner changes and milking management visits can help reduce spikes in BMSCC.
  • Heat Stress & Shade
    Hot days impact milk yield and fertility. Provide shade, adjust milking schedules, and ensure water access. This supports your Animal Wellbeing Plan under the Fonterra Cooperative Difference.
  • Bull Preparation
    Ensure bulls are healthy, vaccinated, and ready to work. Maintain a ratio of 1 bull per 15–20 cows or heifers, and always have backups.
  • Farmer Wellbeing
    Book a holiday. Taking time off after calving and mating is vital for mental health. Plan ahead and support each other.

🐂 YEARLINGS

  • Bull Checks
    Confirm bulls are still working and sound. Replace any lame or injured bulls promptly.
  • Feeding Plans
    Good nutrition is key to growth and pregnancy retention. Talk to your grazier now about summer/autumn feed plans.

🐮 CALVES

  • Vaccinations
    • Lepto – Start from 4 weeks old
    • Clostridials – Use 5-in-1 or 10-in-1 from 2–3 weeks
    • BVD – Vaccinate before 6 months
    • Salmonella – Begin at 3 months if risk is present
    • Scours – Ensure gold colostrum within 6–12 hours
  • Grazing Forms
    Use Arrival Form and Departure Form for smooth transitions.
  • Drenching
    Include anti-coccidials like Turbo Initial for weaned calves.
  • Trace Minerals
    Supplement weaned calves based on vet advice and liver biopsy results.
  • Weighing
    Track growth—small gaps now can become big ones later. Use Growright or similar tools to monitor progress.

Wishing you a successful end to mating and a healthy, productive season ahead.
