Lakasa ti Sirib, DMMMSU Institutional Repository.https://lakasa.dmmmsu.edu.ph/handle/123456789/970Sinay seed meal is a potential source of feed for broilers as feed extender for it contains 18.4% crude protein. This study was conducted to determine the best level of sinay seed meal (10%, 20% and 30%) as feed extender for broilers. This was conducted at Poblacion, Bacnotan, La Union from November 29, 2011 to January 3, 2012. A total of 60 heads of 14-day-old broiler chicks were distributed at random in four treatments following the RCBD with three blocks. Based on the result of the study, broilers fed with different levels of sinay from 10% to 30% comparably performed with those fed with pure broiler starter mash in terms of final weight, gain in weight, feed conversion ratio and profit above feed, medicine and stock cost. However, the feed intake was significantly reduced.en-USThesis
