1. Feed wastage (the #1 cause)
Over-filled feeders, spillage during feed drops, and feed left sitting in a silo long enough to bridge or spoil are the most common — and most fixable — sources of wasted feed. None of this shows up as "extra feed used" until settlement, when it quietly inflates your FCR. Keep feeder pan depth correct for bird age and check silo drops aren't overshooting.
2. Water pressure and line hygiene
Feed intake follows water intake almost exactly. Low line pressure, dirty nipples, or biofilm build-up reduce how much a bird drinks — and therefore how much it eats — without any obvious sign until growth checks fall behind. Flush and check pressure at least weekly, more often in hot weather.
3. Temperature and ventilation stress
Birds outside their thermal comfort zone burn energy on temperature regulation instead of growth. A shed running 2–3°C off target for several days — too hot in the finisher phase, too cold in brooding — measurably worsens FCR even when feed delivery looks completely normal on paper.
4. Litter condition
Wet, caked litter increases ammonia and disease pressure, which pushes birds off feed and slows growth without a single obvious "problem day." Rake and top up problem areas (drinker lines, feeder edges) proactively rather than waiting for visible caking.
5. Prompt mortality removal & health checks
Dead or dying birds still "count" as placed birds consuming feed until they're removed and logged — delayed mort collection quietly inflates FCR by keeping non-productive birds in your feed-consumed calculation for longer than they should be.
6. Know your number — daily, not just at settlement
The biggest reason growers miss FCR problems until it's too late is simple: most only see FCR once, at settlement, weeks after the mistake happened. Checking FCR live — day by day — turns a batch-ending surprise into a same-day fix. Run your current numbers through our free FCR Calculator any time.
FAQ
What is the single biggest cause of poor broiler FCR?
Feed wastage — spillage from over-filled feeders and feed left to spoil — is the most common and most fixable cause of poor FCR on Australian broiler farms.
Does water pressure affect FCR?
Yes. Low pressure or dirty lines reduce water intake, which directly reduces feed intake and slows growth, worsening FCR even though feed usage looks normal on paper.
How much can temperature stress hurt FCR?
A shed running even 2–3°C off target for several days can measurably worsen batch FCR, because birds burn energy on temperature regulation instead of growth.
