ECONOMIC IMPLICATIONS OF MISSED HEAT IN PIG FARMING.
Do you know that not breeding your sow/gilt while on heat comes with a cost??, new farmers and investors listen any missed heat has an implication, it means financial loss because you have to feed her 21 days before she comes on heat again. Here’s a whole breakdown what it means to a farmer 🧑🌾 economically below 👇.
If you don’t breed a sow or gilt while she is on heat (estrus), there are several economic impacts that can affect profitability in pig production. Here’s a breakdown:
⸻
1. Wasted Heat Cycle
• A gilt/sow comes into heat every 18–24 days if not mated.
• Missing a heat cycle delays conception, which delays farrowing (piglet birth).
• Economic effect: Each missed cycle means about 3 weeks lost in production. Over time, this reduces the total number of litters and piglets produced per year.
⸻
2. Reduced Lifetime Productivity
• Gilts have a limited number of productive parities (litters). Delaying first service reduces her lifetime output.
• Example: If a gilt farrows first at 12 months instead of 10 months, you lose one full cycle of piglets over her breeding life.
⸻
3. Feed & Maintenance Costs
• Each extra non-productive day (when the sow is alive but not pregnant or lactating) costs money in feed, housing, labor, and healthcare.
• On average, a non-productive sow day costs #3000–5000 naira/day (this can vary by country).
⸻
4. Lower Farrowing Rate
• Repeatedly skipping heats or failing to mate on time may reduce conception rates in future cycles.
• In gilts, delaying first mating beyond 8–9 months of age can lead to poorer reproductive performance and smaller litters.
⸻
5. Impact on Pig Flow & Market Supply
• Commercial farms often plan piglet batches for weaning, growing, and marketing.
• Skipped cycles disrupt this schedule, leading to:
• Empty farrowing crates.
• Irregular piglet supply.
• Reduced slaughter pig flow, affecting cash flow.
⸻
6. Opportunity Cost
• By not breeding during a heat, you lose the chance to produce ~10–14 piglets (depending on litter size).
• That’s lost revenue from piglet sales or reduced stock for fattening.
⸻
✅ Summary:
Not mating a sow/gilt in heat leads to wasted time, higher feed costs, fewer piglets per year, and lower overall profitability. In commercial terms, each missed heat is a direct economic loss.
Please be intentional about missing heat in your business because obviously from my explanation you are practically doing awoof (financial giveaway) for your staffs and animals while not being productive. STOP IT NOW if you want to be profitable.
