What is corrected FCR (cFCR)?

cFCR normalises Feed Conversion Ratio to a common 2.45 kg reference weight so batches of different average bird weights can be compared fairly. The formula is cFCR = FCR − (average weight in kg − 2.45) × 0.27.

Q: What is a good FCR for broilers in Australia?

Modern Australian broiler batches under Ingham's, Baiada or BPL Adelaide contracts typically target 1.55–1.70 FCR by day 42, depending on breed (Ross 308, Cobb 500) and target catch weight. Under 1.55 is excellent, above 1.85 is a problem batch.

Q: How do I improve my FCR?

The biggest levers are: precise feed drops (no over-fill / no run-out), tight temperature and ventilation between 30–34°C then stepping down, clean water lines, litter management, and prompt mortality removal. Broiler Base Mate's Farm Buddy AI recommends drop timing per shed to reduce carry-over waste.

The formulas we use

Standard FCR

FCR = Total feed consumed (kg) ÷ Total live weight caught (kg)

Corrected FCR (cFCR)

cFCR = FCR − (average bird weight in kg − 2.45) × 0.27

The 2.45 kg reference is the industry standard used by Aussie broiler processors, and the 0.27 slope corrects FCR up or down when your average bird weight is heavier or lighter than 2.45 kg. This makes batches of different weights directly comparable.

Cage rating & Efficiency rating

Cage rating = 39.5 ÷ corrected batch age (days)

Efficiency rating = ((1.78 ÷ cFCR) × 0.7) + (cage rating × 0.3)

Efficiency rating drives the grower payment $ on most Aussie contracts — higher is better.

What's a good FCR for Aussie broiler batches?

Batch quality	FCR range	cFCR range	Notes
Excellent	1.45–1.55	1.42–1.50	Top 10% of Baiada / Ingham's growers
Good	1.55–1.65	1.50–1.58	Contract-comfortable, healthy margin
Average	1.65–1.75	1.58–1.68	On target, payment usually stable
Below target	1.75–1.85	1.68–1.78	Review feed drops, ventilation, litter
Problem batch	1.85+	1.78+	Investigate: mortality spike, feed spoilage, cold shed

FAQ

What is a good FCR for broilers in Australia?

Modern Aussie broiler batches typically target 1.55–1.70 FCR by day 42 on Ingham's, Baiada or BPL Adelaide contracts. Under 1.55 is excellent; above 1.85 is a problem batch.

Why is my FCR different from my integrator's FCR?

Common reasons: feed-left-in-silo not counted, catch weight includes shrink allowance, morts not deducted from placed count, or dockets missing from the tally. Broiler Base Mate reconciles all of these automatically from AI-scanned dockets and daily silo readings — see your live FCR every day, not just at settlement.
