Native, broiler and layer lines, grouped by how well the figures behind them were measured. Every number carries its source, and the columns nobody has filled say so.
DOST-PCAARRD station records, off institutional flocks on one protocol. These four are the only figures on this page that may honestly be compared with each other.
native · Bohol, Central Visayas
Boholano lays fewer eggs than Darag and is the only native line whose weight at a stated age is published at all. The curve stops at day 120 and drawing it further is not evidence.
DOST-PCAARRD · Aug 2026
native · Bicol Region, southern Luzon
Camarines lays the same 62 eggs as Boholano and has the second-lowest published fertility of the documented Philippine native lines. The published percentages do not multiply.
DOST-PCAARRD · Aug 2026
native · Panay Island, Western Visayas
Darag is the best-documented native line in the country on eggs and the least documented on meat. This page prints both halves, including the columns nobody can fill.
DOST-PCAARRD · Aug 2026
native · Zamboanga Peninsula, Western Mindanao
A breeding programme that raises egg number can pay for it in age at maturity. ZamPen is the one Philippine native line where both halves of that trade were published.

Single journal papers, each with its own method, flock size and year. Real measurements, and not measurements of the same thing.
native · Caraga Region, northeastern Mindanao
Forty birds at Caraga State University produced the fullest published record of any Philippine native line. It also produced two different annual egg figures, and nobody reconciled them.
Austral TM Jr · Aug 2026
native · Palawan
Paraoakan is one of only two Philippine native lines with a measured adult weight in print. The same study also carries recalled figures, and the two halves must not be read the same way.
Tuquero FML (2026) · Aug 2026
What raisers told a surveyor, or one small trial, or nothing. Useful for a sense of scale and not for a comparison.
native · Batangas, Calabarzon
Every feed number quoted for Philippine native chickens traces back to one 20-bird thesis on the Banaba strain. This page says what it measured and what it could not.
native · Bolinao, Pangasinan, Ilocos Region
Bolinao is the Philippine native line with the most measured laying record. The feed conversion in it is a layer figure, and reading it as a grow-out figure is the easiest mistake here.
Tadeo DB (2024) · Aug 2026
Published by the breeding company, for a controlled house on a formulated ration. A Philippine backyard is neither, and the gap is the point.
layer · Hy-Line International breeding programme, sold worldwide
The brown commercial layer behind most backyard point-of-lay pullets. Its published standards are cumulative to a flock age, not eggs per year, and the difference matters.
Hy-Line International · Aug 2026
broiler · Aviagen breeding programme, sold worldwide
Most Philippine broiler chicks are Ross or Cobb, and the numbers everyone quotes come from a breeder booklet written for a controlled house. Here is the table and here is the gap.
