| Harvest | Liveweight per bird | Feed per bird | Sacks per 100 birds |
|---|---|---|---|
| Day 28 | 1.66 kg | 2.5 to 3.0 kg | 5.0 to 6.1 |
| Day 35 | 2.36 kg | 3.5 to 4.3 kg | 7.1 to 8.6 |

Ross 308 AP, the feed conversion Philippine open-sided farms aim at, 50 kg sacks, no death loss. Multiply by your own flock: 20 manok is a fifth of every figure here. This is the one table on the page that does not care what feed costs this week.
The gap nobody budgets for
Two columns, never averaged into one. Both are targets: one is a breed company's aim for a controlled house abroad, the other is what Philippine growers aim at in an open-sided one. The third column is what the gap between the two costs you in extra feed.
| Harvest | Breed table FCR | PH target FCR | Extra feed |
|---|---|---|---|
| Day 28 | 1.26 | 1.50 to 1.83 | +46% |
| Day 35 | 1.39 | 1.50 to 1.83 | +32% |
| Day 42 | 1.52 | 1.50 to 1.83 | +21% |
The left column is Aviagen own performance objective for a climate-controlled house. The right is what the 16 open-sided growers among the 48 Datuin et al. split by housing told them they were shooting for, off a table the paper labels targets. Two aims, then, not an aim against a result, and 33% of those growers said they do not reliably get there. So the right column is a floor and your own bill lands above it. Neither is averaged into the other, kasi averaging two sources that disagree is not a better number, it is a made-up one. And these were commercial growers: nobody has published a Philippine backyard figure at all. One thing about the day 28 row: this strain is 1.66 kg there, which lands between the two products the paper defines, lechon manok under 1.6 kg and big bird over 1.7 kg. It says nothing about the hundred grams in between. That row is costed on the big-bird band, and this sentence exists so the choice is visible rather than silent.
Magkano, at your dealer's price
Find the row that matches what your dealer quoted you this week. Every figure is for a 50 kg sack. Ang presyo kada sack at ang presyo kada kilo ay iisang numero lang sa magkaibang unit: divide a sack price by 50 and you have the per-kilo one. A reader holding a 25 kg sack who reads the 50 kg row gets an answer wrong by double.
| Sack price | Day 28 | Day 35 | Day 42 |
|---|---|---|---|
| ₱1,500 | ₱74.56 to ₱90.97 | ₱106.20 to ₱129.56 | ₱138.87 to ₱169.42 |

The sack price is yours, not ours. No Philippine source publishes what a sack of finished feed costs by brand or tier, so this axis is a scan range, not a price list. Prices are for a 50 kg sack: if your sack is 25 kg, halve the peso figure before you find your row. Write down the dealer and the date beside whatever you paid.
Why this page asks you for the feed price
No Philippine source publishes the price of a sack of finished commercial feed by brand or tier. The Bureau of Animal Industry publishes feed ingredients in pesos per kilo, and that is a different figure. This tool therefore asks you for the sack price rather than inventing one, and the answer it gives is dated by your own dealer visit. That gap is G-15 in the archive.
Against liveweight, which is how you get paid
A buyer quotes you per kilo, so this is the same bill in the units the sale happens in. Compare a row here against the farmgate series on the broiler price page. The difference is everything the feed bill does not cover: the sisiw, the brooding, the meds, the hakot, and your own time.
| Sack price | Day 28 | Day 35 | Day 42 |
|---|---|---|---|
| ₱1,500 | ₱45.00 to ₱54.90 | ₱45.00 to ₱54.90 | ₱45.00 to ₱54.90 |
| ₱1,600 | ₱48.00 to ₱58.56 | ₱48.00 to ₱58.56 | ₱48.00 to ₱58.56 |

Feed pesos per kilo of liveweight produced. Compare it to the farmgate price on the presyo pages and the gap is what has to cover the chicks, everything else and your time.
What the grid assumes
- Liveweight at day 28 is 1657 g per bird, read straight off the Ross 308 AP Broiler: Performance Objectives (2022), Aviagen as-hatched table. That is liveweight with feed in the gut, the same basis PSA farmgate uses, not a dressed weight from the palengke.
- Liveweight at day 35 is 2360 g per bird, read straight off the Ross 308 AP Broiler: Performance Objectives (2022), Aviagen as-hatched table. That is liveweight with feed in the gut, the same basis PSA farmgate uses, not a dressed weight from the palengke.
- Liveweight at day 42 is 3086 g per bird, read straight off the Ross 308 AP Broiler: Performance Objectives (2022), Aviagen as-hatched table. That is liveweight with feed in the gut, the same basis PSA farmgate uses, not a dressed weight from the palengke.
- 100 of 100 birds reach harvest at 0% death loss. Chicks are paid for on placement; feed here is charged only against the kilos that survive to be sold.
- Feed conversion is 1.5 to 1.83, the band Philippine open-sided farms growing big birds gave Datuin et al. (2022) as their target, a big bird being what the paper defines as over 1.7 kg liveweight. At day 28 this strain reaches 1.657 kg.
- Feed conversion is 1.5 to 1.83, the band Philippine open-sided farms growing big birds gave Datuin et al. (2022) as their target, a big bird being what the paper defines as over 1.7 kg liveweight. At day 35 this strain reaches 2.36 kg.
- Feed conversion is 1.5 to 1.83, the band Philippine open-sided farms growing big birds gave Datuin et al. (2022) as their target, a big bird being what the paper defines as over 1.7 kg liveweight. At day 42 this strain reaches 3.086 kg.
- The livability of 94 to 95% and the harvest window of 30 to 34 days sit in the same table of the same paper, one row over, so they are aims as well and not survival or age anybody counted. Compare them against the day count and death loss you entered, and expect your own flock to sit outside them rather than inside.
- Feed costs PHP 1800 for a 50 kg sack, which is PHP 36 per kilo. You supplied that price; nothing on this site published it. Note the dealer and the date beside it.
What it does not cover
- The growth tables are Aviagen and Cobb-Vantress performance objectives for controlled commercial housing. They are what the bird is capable of, not what a backyard flock in Philippine heat achieves.
- The two strain tables disagree and neither is averaged into the other. Cobb500 is heavier and hungrier than Ross 308 AP at the same age. Pick the strain you actually placed.
- Feed is charged against the liveweight produced, not against the birds placed. Birds that died partway through ate feed too, so this figure understates the real bill. Correcting it honestly needs a mortality-timing curve and no Philippine source publishes one (G-1).
- Both tables state cumulative feed conversion including placement weight and excluding mortality. That is the source definition and it is not the same as sacks-fed divided by kilos-sold.
- No Philippine source publishes the price of a sack of finished feed (G-15), so the peso side of this answer is only as good as the price you typed in. Write down the date and the dealer.
- At 1.657 kg this batch falls between the two products Datuin et al. define, lechon manok under 1.6 kg and big bird over 1.7 kg. The paper says nothing about the gap. The big-bird range is used here and this line exists so that choice is visible rather than silent.
Why the breed table underfeeds you
Every feed calculator online will tell you a broiler eats about 1.2 kg of feed for every kilo it gains. That figure is real, it comes from Aviagen's own performance objectives, and it describes a bird in a climate-controlled house in a country that is not this one. The nearest Philippine figure is not a measurement either. Datuin et al. (2022) asked 55 commercial broiler farms, 48 contract growers and 7 integrators, what they were aiming at, and split the growers by housing. The 16 open-sided ones answered 1.50 to 1.83, and that is the band this page runs on. A third of the growers then said they meet their own targets only sometimes or not at all. Kung sa breed table ka nag-budget, kulang ang puhunan mo ng halos isang-katlo bago ka pa magsimula.
- Cyclic heat stress cuts broiler feed intake by about 15%, roughly 1.5% for every degree C, and the paper puts no temperature range on that one. Constant heat stress cuts it 25 to 45%, about 3.5% per degree C between 22 and 35 (Teyssier et al. 2022, Frontiers in Physiology).
- At 32 degrees C, weight gain falls 21% under cyclical heat stress and 36% under constant heat stress (Kpomasse et al. 2021, Veterinary Medicine and Science).
Those two are review papers, not Philippine measurements, and nothing on this page multiplies by them. They are here to say why the gap sits where it does, and why a third of the growers in that survey fall short of their own target. Manufacturing a Philippine growth curve by applying a percentage to a European one would be inventing data.
The Philippine reality gap
The growth and feed conversion tables here are Aviagen's and Cobb-Vantress's own performance objectives. They describe a controlled house in another country, and they state what the bird is expected to do rather than what anybody weighed. The Philippine figure set against them is a second set of aims, not a measurement that corrects the first: Datuin et al. (2022) asked 55 commercial broiler operations what they were working towards, and Table 5 of that paper is headed "targets of growers". Only its 48 contract growers were split by housing, and the 16 open-sided ones gave 1.50 to 1.83 for big birds and 1.50 to 2.00 for lechon manok, while a third of those growers admitted they hit their aim only some of the time, or not at all. So treat both bands as a floor. Real open-sided conversion sits at the top of them or past it, which means costing the batch at 1.83 before you cost it at 1.50. Ross's day-28 row is 1,657 g at a cumulative 1.257, inside the Philippine 1.6 to 1.7 kg harvest band, so the top of the Philippine band is 45.6% more feed than the breed table. Datuin's respondents were 48 contract growers and 7 integrators rather than hobbyists, and no Philippine backyard feed conversion figure has been published at all, which is G-1 in the archive.
