Ilang buwan bago mabenta ang native, at magkano ang isa?

Transcribed unchanged from the Boholano growth paper: the mean liveweight and its standard deviation at each age the study measured, in the grams it published. A chick weighs 28.26 g on the day it hatches. The SD column is the finding rather than a caveat on it: at day 120 it is 151 g either side of a 736 g bird, over 20 percent, which is why the band and not the mean is the answer. Past day 120 the tool refuses, because past the last row it would be drawing a line to a weight nobody measured.

The kilo that is not there

Ask what a native chicken weighs at market and you will be told 1.0 to 1.2 kg. On the one Philippine dataset with a published growth curve, a Boholano bird averages 736 g at four months, and even a bird one standard deviation above the mean is under 900 g. A figure of 800 g to 1.0 kg in 15 to 16 weeks circulates for the Darag line; it could not be traced past a search result to a document anybody could open, so it is not on this page and is not in the arithmetic.

That is the whole reason this page leads with the table rather than with a calculator. The arithmetic below is easy; the disagreement is about the input. If you have told a buyer you will bring 1 kg birds in four months, the one Philippine study that weighed them says you will bring 736 g birds, and the difference is a third of your gastos.

What one bird is worth, by the age you sell it

The price below is ₱223.95 per kilo LIVEWEIGHT, the PSA farmgate figure for 2026-06-30 as it stands in this site's archive. Liveweight, not dressed, and not per bird. PSA farmgate. The full series is at /presyo/native-chicken-farmgate.

Computed for 30 birds at 20% death loss, which is DOST-PCAARRD's own programme figure rather than one picked here, at the archived PSA farmgate price above. Flock size cancels out of both peso columns, so only the age moves them. Read the last column and not the one before it: a broiler turns over in about 35 days and this bird in 120, so revenue per bird is the wrong comparison and revenue per bird per MONTH is the one that decides. Neither column is profit. There is no cost side on this page at all, and the reason is under the table.

What this page will not tell you

Nobody publishes what a Philippine native chicken eats. A growth curve exists and is good, egg production by line exists, and feed intake does not: not grams per bird by age, not an FCR, for any PH native line, in PCAARRD's breed information system or in the PJVAS growth paper this page runs on. So this tool reports how long, how heavy and what it is worth, and it does not report what it cost you. The alternative was to borrow a broiler feed conversion, which is biologically wrong for a bird that takes four months to reach 700 grams, and it would have been invisible in the answer.

So there is no cost column here, no margin and no profit, and none of the three is coming. It is recorded as gap G-19, with what was checked and who would have to publish it. If you want the other half, weigh a sack against a batch of your own birds; it is the number nobody has.

The anchor everybody quotes is a 2023 figure

One native farmgate price has circulated across Philippine poultry content for years, and it sits well below what the archive behind this page reads. Same PSA series, the same month three years running: ₱206.29 in January 2024, ₱221.79 in January 2025, ₱224.12 in January 2026. So the old figure is not a different market, and it is not the farmgate-against-trade gap that G-4 assumed before the series was pulled and the hypothesis turned out wrong. It is stale, and a page still quoting it is valuing your bird at 2023. The gaps page carries what it was and where it came from.
