FCR Calculator
Two real-world examples — a grower pig benchmarked against Philippine standards, and a full-cycle batch with mortality adjustment and feed cost per kg gain. Learn what FCR numbers actually mean for your profitability.
What is FCR?
FCR (Feed Conversion Ratio) is the amount of feed (in kg) needed to produce 1 kg of weight gain. A pig that eats 300 kg of feed and gains 100 kg has an FCR of 3.0. Lower FCR = more efficient = lower feed cost per kg of meat. Philippine benchmarks are higher than international standards because of tropical heat stress, which reduces feed efficiency. A FCR of 3.0–3.4 is average for Philippine conditions; below 2.8 is excellent; above 3.8 is a problem.
Example 1 of 2
A farmer records exactly how much feed one grower pig consumed over 60 days, weighing it at the start and end of the grow-out period. This is the simplest way to measure FCR on your farm and compare against the Philippine benchmark for the grower phase.
Inputs
| Input | Value |
|---|---|
| Starting weight | 25 kg |
| Final weight | 60 kg |
| Total feed consumed | 107 kg |
| Breed | Large White / Landrace (optional) |
| Number of days | 60 days (optional — enables ADG and ADFI) |
| Feed cost per kg | ₱32/kg (optional — enables cost per kg gain) |
| Head count | 1 pig |
Results
| Result | Value | Notes |
|---|---|---|
| Weight gained | 35 kg | 60 kg − 25 kg |
| FCR | 3.06 | 107 kg feed ÷ 35 kg gain |
| Rating | Average | PH grower benchmark: 2.2–2.8; 3.06 is slightly above |
| Phase detected | Grower | 25→60 kg midpoint = 42.5 kg |
| ADG (average daily gain) | 0.58 kg/day | 35 kg ÷ 60 days |
| ADFI (avg daily feed intake) | 1.78 kg/day | 107 kg ÷ 60 days |
| Feed cost per kg of gain | ₱97.93/kg | 3.06 FCR × ₱32/kg feed |
What this means
An FCR of 3.06 for the grower stage is rated Average under Philippine benchmarks (2.2–2.8 is the target range). This pig needed about 10% more feed per kg gained than the upper end of the benchmark. It is not alarming but points to room for improvement.
The ADG of 0.58 kg/day is below the Large White / Landrace breed average of 0.65 kg/day. This can indicate heat stress (common in March–May), suboptimal feed quality, health issues, or overcrowded pens. Check: Is the pig getting enough water? Is the pen ventilated? Is the feed being stored dry?
At ₱32/kg feed, this pig costs ₱97.93 in feed per kg of weight gained. If you sell at ₱130/kg live weight, your gross margin per kg of gain is only ₱32.07 — thin. Improving FCR from 3.06 to 2.6 would drop feed cost to ₱83.20/kg, adding ₱14.73 per kg of gain or roughly ₱516 extra profit for this 35 kg grow-out.
Bisaya / Cebuano
Ang usa ka grower nga baboy (25→60 kg, 60 ka adlaw, 107 kg feed) adunay FCR nga 3.06. Kana nagpasabot nga ang baboy nakakaon og 3.06 kg feed para sa matag 1 kg nga natambok.
Ang rating mao “Average” — dili maayo, dili pud delikado. Ang target para sa grower stage sa Pilipinas mao ang FCR nga 2.2–2.8. Ang atong baboy hapit 10% ka inefisyente kaysa sa target.
Unsay mahimong hinungdan? Kainit (labi na Marso–Mayo), dili maayong pagpainom, siksik nga kulungan, o feed nga dili himsog. Kon mapababa ang FCR gikan 3.06 ngadto sa 2.6, makatipid ka og halos ₱516 sa feed para sa usa lang ka baboy sa kining yugto.

Example 2 of 2
A farmer raises 10 commercial hybrid pigs from 10 kg to 95 kg over 120 days. They lost 1 pig (mortality) mid-cycle. They want the true FCR for surviving pigs only — the mortality-adjusted FCR — plus the cost in pesos per kg of gain.
Inputs
| Input | Value |
|---|---|
| Starting weight | 10 kg per pig |
| Final weight | 95 kg per surviving pig |
| Total feed consumed | 2,550 kg (for all 10 pigs across 120 days) |
| Head count | 10 pigs |
| Number of days | 120 days |
| Mortalities | 1 pig |
| Feed cost per kg | ₱30/kg (slightly below commercial rate) |
| Breed | Commercial Hybrid (optional) |
Results
| Result | Value | Notes |
|---|---|---|
| Weight gain (per pig, starting weight) | 85 kg | 95 kg − 10 kg |
| Total gain (10 pigs) | 850 kg | Used as denominator for raw FCR |
| Raw FCR | 3.0 | 2,550 kg feed ÷ 850 kg gain |
| Surviving pigs | 9 | 10 − 1 mortality |
| Mortality-adjusted FCR | 3.33 | 3.0 × 10 ÷ 9 — the real efficiency per survivor |
| Rating (cumulative) | Average | PH cumulative benchmark: 2.8–3.5 |
| ADG | 0.71 kg/day | 85 kg ÷ 120 days |
| ADFI | 2.13 kg/day | 2,550 kg ÷ 10 pigs ÷ 120 days |
| Feed cost per kg gained (raw) | ₱90.00/kg | 3.0 × ₱30/kg |
| Feed cost per kg gained (adjusted) | ₱99.90/kg | 3.33 × ₱30/kg — true cost per surviving pig |
What this means
The raw FCR of 3.0 looks fine — right in the middle of the Philippine cumulative benchmark (2.8–3.5). But this number ignores the 1 dead pig, whose feed was consumed without producing a saleable animal. The mortality-adjusted FCR of 3.33 is the number that actually matters for profitability — it tells you what each surviving pig truly "cost" in feed efficiency terms.
The adjusted feed cost per kg of gain rises from ₱90 to ₱99.90 per kg. If your feed was cheaper (₱28/kg instead of ₱30/kg), adjusted cost drops to ₱93.24/kg. If mortality had been zero, it would be ₱90/kg. The mortality-adjusted FCR makes the cost of each dead pig visible — which raw FCR does not.
At a market price of ₱130/kg, this farmer earns ₱130 − ₱99.90 = ₱30.10 per kg of gain in gross feed margin. Over 85 kg of gain per surviving pig × 9 pigs = 765 kg total gain = ₱23,027 gross feed margin for the batch. That is before piglet cost, medicine, and labour.
Bisaya / Cebuano
Ang usa ka batch sa 10 ka baboy (10→95 kg, 120 ka adlaw, 2,550 kg feed) adunay raw FCR nga 3.0 — maayo. Apan namatay ang usa ka baboy. Ang mortality-adjusted FCR mao 3.33 — mao kini ang tinuod nga FCR para sa mga nabuhi.
Ang nagpasabot niini: ang matag nabuhi nga baboy nakakaon og feed nga para rin sa patay na baboy. Mao nga ang tinuod nga gastos sa feed mao ₱99.90 matag kg ng natambog — dili ₱90.
Kon ang presyo sa baboy ₱130/kg, ang gross margin sa feed mao ₱30.10 matag kg. Para sa tibuok batch (9 nabuhi × 85 kg = 765 kg gain), ang gross feed margin mao halos ₱23,000. Idugang pa ang gastos sa piglet ug tambal para makita ang totoong tubo.
Hinumdumi: Ang matag namatay nga baboy nagpataas sa imong adjusted FCR. Mao nga ang paglikay sa pagkamatay (pinaagi sa bakuna ug biosecurity) makapababa sa imong gastos — dili lang human terms, kundi pera usab.
