Pro Tips
Dry Period: Stop milking 60 days before the due date to allow udder tissue to regenerate.
Nutrition: Increase protein and energy in the 'close-up' ration (last 3 weeks) to prevent ketosis.
Isolation: Move the cow to a clean, dry calving pen 1-2 weeks before the expected date.
Observation: Watch for udder filling and relaxation of pelvic ligaments ('springing') as signs of imminent labor.

Fun Facts
"Cattle gestation is ~283 days, very similar to the 280-day average for humans."
"Bull calves (males) are typically carried 1-2 days longer than heifer calves."
"A cow's body temperature often drops by 1°F about 24 hours before calving begins."
"Cows are 'polyestrous', meaning they cycle continuously all year round until bred."
