Abstract: Jimenez, Minerva Joy C. Cavite State University, Indang, Cavite. B. S. Thesis "Response of Two Strains of Broiler to Feed Containing Single-Cell Protein". Dr. Pedro Q. Olabe, thesis adviser. A study was conducted to determine the response of two broiler strains to rations containing two levels of Single-Cell Protein (SCP). Two strains (Avian 43 and Anak 180) and two treatments (Treatment I, containing 0% SCP and Treatment II, containing 60/0 SCP) were used in the study. Results showed significant differences (P<0.05) in body weight and feed conversion efficiency between strains from first to sixth weeks and between treatments during the sixth week. No significant differences (P>0.05) were observed on the feed consumption of the birds. Strain B consumed a lower amount of feed but was not that efficient. Birds subjected to Treatment II were more efficient (P<0.05) than those in Treatment I. Mortality was very low and occurred only in Strain A. Average dressed weight and dressing percentage were significantly higher (P<0.05) in Strain A than Strain B and in Treatment II than Treatment I. No significant differences (P>0.05) were observed in the relative weights of gizzard, liver, heart, and intestines. Generally females have heavier weights of these organs than males. There were Sex x Treatment and Strain x Sex x Treatment interactions (P<0.01) in the relative weight of the feather. Male birds from Treatment I-Strain A had heavier feather weight than females. Strain B had heavier feather weight than Strain A and Treatment I heavier than Treatment II. Abdominal fat pad was influenced by Sex and Strain x Treatment interaction. Females have significantly (P<0.05) heavier abdominal fat pad. Under Treatment I, Strain B had heavier fat pad than Stain A . While under Treatment II, Strain A was heavier than Strain B. No significant differences (P>0.05) were observed in the odor, tenderness, off-flavor and general acceptability of the meat from the two strains subjected to two levels of SCP. Strain A was more appealing (P<0.05) than Strain B. Strain A and Treatment I was more profitable than Strain B and Treatment II. Overall, Strain A subjected to Treatment I gave the highest return.
