  • Before loading gun, warm insemination gun by rubbing briskly with a paper towel
  • Wrap assembled gun in clean paper towel and place in your clothing close to your body to keep warm when traveling to animal

November 2021 Tip- Fresh Cow Management

Fresh cow management impacts a cow’s milk production, health and reproductive performance.  Key components include:

  • Minimize stress on these cows by providing plenty of bunk space (≥30 inches/cow) and resting space (1 stall or 100 sq ft /cow).
  • Do not house fresh cows with sick cows since their immune system is naturally depressed first few days after calving.  Delay vaccinations for at least 10 days post calving.
  • Observe cows daily for early signs of disease.
  • If possible, house fresh cows separately from rest of milking herd for minimum of 7-14 days.  Heifers also do better housed and fed separately from older cows.
  • Feed additives, i.e. choline, may be most cost effective in fresh and prefresh diets.
