Varias, Elvira E. , Cavite State University, Indang, Cavite. B.S. Thesis "Strain X System of Feeding Interaction on Broiler Performance". Dr. Adrew T. Bunan, Thesis Adviser. Three commercial broiler strains (Avian 43, Arbor Acres x Anak 2000 and Anak 180) were used to compare the influence of strain and feeding system on broiler growth and efficiency. The strains were either choice-fed or conventionally-fed. The choice-fed group was given separate sources of protein and energy fortified with vitamins and minerals. The conventionally-fed group was given commercial booster, starter and finisher rations. All groups were fed ad libitum. No strains effect (P>0.05) was observed on body weight, feed consumption, feed conversion efficiency, breast fleshing and relative weight of feather and internal organs. Strain C had better (P<0.05) breast fleshing than Strain B. than of Strain B was better (P<0.05) than Strain C. All but feed consumption were not influenced (P>0_05) by feeding system. Conventionally-fed birds consumed more feed (P<0.05) than those that were choice-fed. Strain A had the highest monetary return. In contrast to Strains B and C, return in this strain was higher with conventional feeding.
