Feed Cost per Broiler: What a Kilo of Liveweight Actually Eats

₱54.00 to ₱65.88 per kilo of liveweight at day 28. ₱54.00 to ₱65.88 at day 35. ₱54.00 to ₱65.88 at day 42.

Akala ng marami na mas mura kada kilo ang manok na maagang binenta, at doon nagsisimula ang maling budget. That is one band printed three times, at an illustrative ₱1,800 for a 50 kg sack. The feed cost tool runs the same grid from ₱1,500 to ₱2,400 per sack in ₱100 steps, ten rows deep, and every harvest-day column in every row reads identically.

The arithmetic fits on one line: sack price, divided by the 50 kg inside the sack, times the feed conversion. Harvest day only gets in through that last term. The one Philippine feed conversion figure anybody has published is a table of grower targets, and it carries a single band per product with no trend by age, selected by liveweight rather than by day, which is what makes it fair to carry out to day 42. So the flatness across those columns is an absence of measurement rather than a measurement. The survey’s own harvest windows are narrower than the grid, nothing published varies the band by age, and the calculator holds it steady because there is nothing to vary it by.

Harvest day is a cash question, not a feed-cost question

A keeper weighing day 28 against day 42 is deciding about money in hand, about mortality risk over two extra weeks, about how long the kulungan stays occupied before the next batch, and about what the buyer actually wants on the hook. Feed cost per kilo sold is not on that list.

Feed cost per kilo of liveweight, three rows lifted out of the ten on the feed cost tool. The sack prices are a scan axis you replace with your own quote, not observed prices. The band inside each cell is the 1.50 to 1.83 feed conversion Datuin et al. (2022) recorded as the target of growers in Philippine open-sided housing, not as their result.

Kilos of feed and kilos of manok both scale with the day, so the ratio between them survives the division.

The two extra weeks cost something, just not on this line. Ang feeds na naubos ng manok na namatay ay hindi na babalik, and the breed table leaves that feed out entirely. Whatever your own losses look like, they run for as long as the batch runs. A coop that empties at day 28 is also free for the next batch two weeks sooner, which is a throughput question no feed grid can answer.

Which turns the harvest decision into a plainer one than most guides make it. Sell early because you need the cash back sooner, because you cannot carry the mortality risk, or because your suki wants a 1.5 kg bird. Sell late because the buyer pays for size. Do not sell early to save on feeds per kilo.

So ano ang nagbabago kapag pinatagal mo sila?

Liveweights are as-hatched Ross 308 AP, 1,657 g at day 28 and 3,086 g at day 42 (Ross 308 AP Broiler: Performance Objectives, 2022), eaten at the Philippine target feed conversion band, in 50 kg sacks. Two decimals because 1.7 kg is the floor of the Datuin big-bird band and a day-28 bird sits 43 g under it. This is the same grid the tool prints with no peso in it, down to the same 10 g.

Doubling the sacks is the whole difference. A batch of 100 taken to day 42 buys between 9.3 and 11.3 sacks against 5.0 to 6.1 at day 28, which is roughly twice the puhunan tied up in feed before a single bird is sold. Ang tanong doon ay kung kaya ng bulsa mo, hindi kung mas mataas ang margin.

Draw the same batch out and what is missing from the picture is the point. Day 0 at one end of the span, Harvest at the other, and not one peso anywhere on it.

The three boxes along the bottom are the three exits out of the table above. Day 28 carries 5.0–6.1 sacks under a 1,657 g bird, Day 35 carries 7.1–8.6 under 2,360 g, Day 42 carries 9.3–11.3 under 3,086 g, per 100 broilers at 50 kg a sack, and the arrow drawn across all three is labelled about twice the sacks. Sacks are the only quantity on the drawing that moves with the harvest day. Ang gastos kada kilo ay wala doon dahil wala itong ginagalaw, and a picture of a flat line would have been a picture of nothing.

Day 28 sits in a dashed box marked gap in the source, and the next section is about why. The two cuts across the span are dashed for a different reason: Starter, Grower and Finisher are real, but each boundary carries a question mark instead of a day, and the note under the bar says no issuance sets the switch day, read the sack.

Those cuts are also why those sacks are not one product. Kung isang presyo lang ang hawak mo, tantiya iyon at hindi budget. A batch buys starter, grower and finisher at three separate prices off the same dealer, which the feeds pillar sets out, so a count of bags is not yet an invoice.

The money comes back bigger too, since the bird is heavier. Bigger out, bigger in, and the gap between them is the thing worth answering before you place the batch.

Anong FCR ang totoo sa open-sided na kulungan?

Isa lang ang Philippine na bilang na na-publish, at hindi ito galing sa bakuran. It is also not a record of what any farm achieved. The 1.50 to 1.83 the tool runs on is the open-sided row of a table of production targets in Datuin et al. (2022), a survey of 55 commercial broiler farms whose 48 contract growers are the only ones split by housing, 16 of them open-sided, for big birds harvested between day 30 and day 34. Ang tinanong sa kanila ay kung ano ang pinupuntirya nila.

The same paper then puts 33% of those growers at meeting their targets only sometimes or not at all, blaming chick quality, weather, disease and late inputs. So the achieved number sits at the top of the band or past it. Budget on 1.83 and treat anything nearer 1.50 as a good year. The growth cluster reads the same table row by row.

Set that target band against what Aviagen publishes for the same bird at each age and the gap moves:

At day 28 the top of the Philippine range runs 45.6% above the Ross cumulative feed conversion of 1.257. At day 35, against 1.386, it is 32.0%. At day 42, against 1.516, it is 20.7%. Those run against the day-anchored Ross figure rather than the rounded 1.20 the feeds pillar uses for the same comparison, which is why its number for the same gap comes out larger. Either way an aim is being held against a measurement, and only one side of the comparison has a house behind it.

Read that sequence the wrong way and it says a Philippine farm catches up as the batch ages. It says the opposite. The Philippine band does not vary by age in the source, so nothing in it is improving. What moves is the Ross column, which climbs from 1.257 to 1.516 over those two weeks because a heavier bird converts feed less efficiently. Hindi umaangat ang farm, bumababa ang curve.

No Philippine source has published a backyard feed conversion figure, gap G-1 in the register, so a 20-bird flock in a bakuran is likelier to sit above 1.83 than inside the band.

The gap is widest at the weight Filipinos actually sell

Ross reaches 1,657 g on day 28, and that weight lands in a hole the source leaves open. Datuin defines lechon manok as a bird under 1.6 kg and a big bird as one over 1.7 kg, and says nothing about the hundred grams between them. So the day-28 column costs a bird the paper classifies as neither product. The tool puts it on the big-bird range and prints a line on the answer saying it did, because the alternative is choosing between two bands in silence. The other band, for birds at 1.6 kg and under, runs 1.50 to 2.00 across a 28 to 38 day spread, looser at the top.

That gap sits where Filipinos actually sell. The paper puts the Philippine target liveweight at 1.6 to 1.7 kg against the 2.1 to 2.5 kg the big producing countries grow to, so a bird in the undefined band is the normal bird here rather than an edge case.

Five sacks per 100 birds, four weeks of work, cash back fast. Mura ang hitsura ng kabuuan, pero ang bawat kilo na binenta mo doon ang pinakamahal na kilo sa buong grid kumpara sa brochure. Day 28 is the widest of the three harvest days against the breed table, at 45.6%.

The answer is not to walk away from that market. Ang lechon manok ang pinakamabilis na cash sa bakuran, at may suki para dito sa halos bawat bayan. Budget it at 1.83, the top of the big-bird band the tool uses at that weight, and higher again if your birds go out under 1.6 kg where the target range reaches 2.00.

Cobb500 does not sit where Ross does. Cobb publishes 1,783 g at day 28 with 2,359 g of feed and a cumulative 1.322, rising to 1.555 by day 42 (Cobb500 Performance & Nutrition Supplement, 2022). Heavier bird, more feed, different ratio. The two strains are not averaged, so every percentage above is against Ross alone, which is what the tool anchors on.

Bakit ikaw ang nagbibigay ng presyo ng sako?

Because no Philippine agency publishes one. Not by brand, not by tier, not at wholesale, gap G-15, and the feeds pillar walks the dead ends. The ₱1,800 used above is an illustration, chosen because it sits in the lower middle of the tool’s scan axis. It is not an observed price and it must not be quoted as one.

What does get published is the raw material. The Bureau of Animal Industry prices 15 feed ingredients weekly in pesos per kilo, and whether that record says feeds went up depends entirely on which window you pick, which is the sibling article’s finding. None of it converts into a sack price.

So get the quote yourself, and write the sack weight beside it: ₱1,800 for a 50 kg sack and ₱900 for a 25 kg sack are the same feed at the same price, and reading one row while holding the other bag doubles your error (the break-even article works through how that goes wrong).

So magkano ang feeds kada kilo ng manok?

Against the June 2026 household farmgate reading of ₱150.31 per kilo liveweight, feed at the illustrative ₱1,800 sack takes 35.9 to 43.8 percent of the gross before you count sisiw, meds, hakot or your own hours. The same month’s commercial establishment series reads ₱118.69 per kilo liveweight, a different seller into a different market level, and against that figure the feed share runs from 45.5 to 55.5 percent.

There is a sack price where the feed alone takes half of what a household seller grosses per kilo, and it is ₱2,053.42 for 50 kg at the top of the big-bird conversion band. That sits above the ₱1,950 midpoint of the tool’s axis but still inside it. A dealer quoting ₱2,100 has put a backyard batch past that line before the chicks arrive.

The whole feed bill for 100 broilers to day 35 is ₱12,744.00 to ₱15,547.68, or 7.1 to 8.6 sacks of 50 kg, laid out before anything is sold. Carry the same 100 birds to day 42 and it is 9.3 to 11.3 sacks. Ang totoong presyo ng sako ay galing sa dealer mo, hindi sa page na ito. The break-even tool adds the sisiw and gives you the farmgate price the batch has to reach.

Questions people actually ask

How much feed does a broiler eat before slaughter?

Aviagen publishes 2,083 g of cumulative feed at day 28, 3,268 g at day 35 and 4,674 g at day 42 for an as-hatched Ross 308 AP in controlled housing (Ross 308 AP Broiler: Performance Objectives, 2022). Philippine open-sided farms eat more than that, and the Philippine figure everybody quotes is an aim rather than a result. Datuin et al. (2022), Philippine Journal of Veterinary and Animal Sciences 48(1):57-69, asked 55 commercial broiler farms what they were targeting and split its 48 contract growers by housing; the 16 open-sided ones gave 1.50 to 1.83 for a big bird. The band puts roughly 2.5 to 3.0 kg of feed into a day-28 bird of 1,657 g and 4.6 to 5.6 kg into a day-42 bird of 3,086 g. Budget on the top of it, for the reason the next answer gives.

How many sacks of feed do I need for 100 broilers? Show the answer

Between 5.0 and 6.1 sacks of 50 kg if you sell at day 28 and around 1.7 kg liveweight, and between 9.3 and 11.3 sacks if you carry the same 100 birds to day 42 and roughly 3.1 kg. The spread inside each figure is the 1.50 to 1.83 feed conversion band that the 16 open-sided farms among the 55 Philippine commercial growers surveyed by Datuin et al. (2022) told them they were aiming at. Nobody has published what those farms actually achieved, so buy nearer the top of each range than the bottom. And buy in three products, not one: starter, grower and finisher are priced separately.

How much does it cost to feed one broiler to market weight? Show the answer

Multiply the sack price your dealer quotes you by the feed the bird eats. A day-28 broiler of 1,657 g eating at the 1.50 to 1.83 feed conversion Philippine open-sided growers aim at takes about 2.5 to 3.0 kg of feed, so a 50 kg sack at ₱1,800 works out at ₱36 per kilo of feed and roughly ₱89 to ₱109 of feed in that bird. No Philippine agency publishes a sack price, so the figure has to be your own.

Why is my feed conversion worse than the breed table says? Show the answer

Breed tables are measured in houses where somebody sets the temperature. Aviagen puts an as-hatched Ross 308 AP at a cumulative feed conversion of 1.257 on day 28 and 1.516 on day 42. The nearest Philippine figure is not a measurement of what farms achieve. Datuin et al. (2022) in the Philippine Journal of Veterinary and Animal Sciences 48(1):57-69 published what 55 commercial farms said they were aiming at, and split its 48 contract growers by housing; the 16 open-sided ones gave 1.50 to 1.83 with livability of 94 to 95 percent. A third of those growers told the same survey they meet their targets only sometimes or not at all. Those were contract growers with technical support rather than backyard flocks, so a bakuran figure sits above that band rather than inside it.
