The average litter size at weaning was 8 pigs. The adjusted 30-day-old pigs averaged 8 kg. The age of the animals was adjusted in comparing the weaning weight since the farms had different piglet-weaning periods.

The farrowing (birthing) interval ranged 150–173 days, averaging 158 days, equivalent to two farrrowings per sow a year.

Animal mortality in the farm averaged 4%. Most of the mortalities were sucklings, weanlings, and growers.

Farrowing rate, however, is a national problem that needs attention. Its average in 2005 was 75%, which was less than the target set at 80%.

The age of sold animals was also adjusted for comparing their weight because of the animals’ different selling age. The price of regular slaughter hogs averaged P78/kg.

The study found that an average P53-worth of feed was needed to produce a kilo of live animal.

On feed rations, around 2% of feeds consumed were booster, 11% prestarter, 18% starter, 32% grower, 9% finisher, 19% breeder/gestating, and 9% lactating rations.

The survey, based on a system and set standards, was conducted by the Livestock Research Division of PCARRD and the Philippine Swine Industry Research and Development Foundation, Incorporated (PSIRDFI). This team has been monitoring swine farms in the country for the past 14 years.

The survey results were recently presented before swine raisers, veterinary drug manufacturers and practitioners, academicians, and government and non-government entities.
