To reduce the cost for used feeder in the piggery some guys started in 1999 a test with feeding partly Gabing San Fernando.

A preliminary study on the feeding of sakwa-based feed rations to swine
fatteners was conducted by the Farming Systems and Soil Resources
Institute (FSSRI) in Barangay Pinagdanglayan, Dolores, Quezon under the
project supported by the Bureau of Agricultural Research (BAR).
Drying of sakwa was tried by air drying, sun drying or through mechanical drier. Air-drying requires at least five days to attain 14% moisture and sun drying, 3 days. Initial trial was also made using the CEAT multi-purpose drier. Chipping of sakwa is done manually or with the use of a mechanical chipper. Manual chipping is slow and laborious with an output of 9-20 kg/hr/person. Slices can either cross-sectional or longitudinal. Longitudinal slices are more advantageous than the cross sectional or oval cuts because they dry faster. Dried chips that are not milled right away are stored in sacks or containers that can be tightly closed to prevent moisture reabsorption. The use of mechanical drier and chipper are potentially economical if operation will be made on a large scale.
In the on-farm trial conducted for the utilization of sakwa-based feed ration for swine fattening, dried sakwa was used as a replacement for the corn component of the feeds. Corn was replaced in the ration at 50% for the grower feeds and 75% for the finisher rations. The feed formulation was prepared in cooperation with Luntian Multi-purpose Cooperative, Inc. (LMC). The LMC milled the dried sakwa and mixed it with the basic feed to a ration.
There were three farmer-partners involved in the trial. Each farmer had nine fatteners which were crossbred of Landrace and Yorkshire from the Institute of Animal Science, UPLB. The fatteners were divided into three groups with the first group serving as the control and was fed with commercially available feeds used in the area. The second group was fed with sakwa based-feed starting from growing stage (about 30-35 kg per head) while the last group was fed with sakwa-based feed only during the finishing stage (60 kg above).
Results of the trial showed no significant differences on the average daily gain (600 g/day) and final weight (80 kg) among the test animals after four months of fattening. Meat color was comparable while back fat thickness was acceptable for all treatments. However, differences in the net benefit was observed. sakwa-based feeds had lower cost compared to corn-based ration. Partial budget analysis showed a higher net benefit in the feeding of sakwa-based feeds to swine starting at the grower stage. Animals fed with sakwa-based rations realized a net benefit of about P 740 per head of swine while those fed with commercial feeds has about P 340 per head.
Considering the savings in the cost of feeds and the insignificant differences in weight gain compared to animals fed with commercial feeds, the use of sakwa-based feed rations for swine has potentials as feeds. Besides, sakwa is a by-product of the production of Gabing San Fernando and produced with less external inputs. There are no imported fertilizers and insecticides component in the production process. The utilization of Gabing San Fernando as the main ingredient of swine feed rations can reduce our dependence on corn as feed ingredients. Studies could also be done on the potential of sakwa-based feeds for cattle fattening and poultry.
