Lakasa ti Sirib, DMMMSU Institutional Repository.https://lakasa.dmmmsu.edu.ph/handle/123456789/1220Due to an increasing cost of medicine, researchers are looking for cheap and locally available substitute for commercial antibiotics. This study was conducted from November 4, 2014 to December 9, 2014 to determine the performance of broilers using different levels of malunggay leaf decoction (10 lm, 20 ml, and 30 ml) as substitute to commercial antibiotics. Sixty day old chicks were distributed in five treatments in three replication using Completely Randomized Design (CRD). Results of the study showed that the different levels of malunggay decoction (10 % to 30 %) significantly affect the weight of birds after brooding, final weight, gain in weight, feed consumption and profit above feed medicine and stock cost but not the feed conversion ratio.en-USThesis
