Feed Beef Cows at Night for Daytime Calving – Vet Guide 2025 🌙🐮

Hi, I’m Dr Duncan Houston BVSc. Spring calving is demanding—labor costs, calf safety, and nighttime weather all challenge producers. But did you know a simple tactic like feeding at dusk can shift 85% of births to daylight? Here’s how dusk feeding works, why it matters, and how Ask A Vet can personalize this practice for your herd in 2025.

1. Why Timing Matters for Calving ⏰

• Beef cows naturally calve between 6 a.m.–6 p.m.
• Nobody can safely monitor cows 24/7—but daytime births are easier to manage.
• Daytime calving means prompt assistance, warmth, and better survival rates.

2. The Dusk Feeding Strategy 🌄

Feeding at dusk changes calving patterns. A major Iowa study involving 1,300 cows across 15 farms found that dusk-fed herds had 85% of calves born between 6 a.m.–6 p.m., compared to the typical ~60% range. The shift can begin within a week—and is more pronounced if started 30 days before calving season.

3. How It Works

• Behavior reset: Dusk feeding becomes a daily scheduling cue for cows.
• Cortisol rhythms: Mealtime cue affects hormonal cycles associated with labor.
• Routine reinforcement: Herds fed at twilight gradually shift biological timing to daylight calving.

4. When to Start

• Ideal: Begin dusk feeding ~30 days before calving season.
• Even mid-season starts work—noticeable shift within 7–10 days.
• Maintain consistent dusk feeding time throughout calving.

5. Ask A Vet Integration 🐾

• 🕒 Custom timing schedules based on your herd size & regional calving dates
• 📱 Herd-level monitoring tools—track calving time shifts in real-time

7. Implementing the Strategy

1. Start dusk feed ~30 days pre-calving
   
2. Document feeding time each evening
   
3. Adjust staffing to match peak calving periods
4. Monitor and record calf birth times
5. Refine with Ask A Vet insights and monthly herd reports

8. 2025 Take‑Home Points

• Dusk feeding shifts calving to daytime—85% day births shown in trials
• Begin ~30 days pre-season or mid-season for quick results
• Ask A Vet personalizes schedules and monitors response
• Better monitoring = better calf outcomes, reduced labor costs

Conclusion

Dusk-feeding your beef cows is a low-cost, easy-to-implement tactic to shift calving into daylight hours, improving calf survival and easing labor demands. When tailored with Ask A Vet’s timing tools, monitoring support, and herd analysis, dusk feeding becomes a powerful 2025 strategy. Ready for smarter calving seasons? Let’s start tonight. 🌟🐄
