摘要

An experiment was conducted to evaluate the effect of different levels of dry fat (dried palm oil) as an energy source and two feed forms (mash and pelleted)used in the finisher stage on growth performance, carcass traits , meat quality and blood serum metabolites of broiler chickens. A total of 450 straight-run Lohmann broiler chicks reared in an open-sided house and fed corn-soybean meal based diet with SBM oil as a source of energy from 1-28d of age. On d 28 birds were randomly assigned to 6 dietary treatments of 3 different levels of dry fat (2, 4 and 6%) and 2 forms of feed in 3 x 2 factorial arrangements. Each treatment has 3 replicates with 25 birds each (75/treatment). Experiment lasted for 42d. Processing yields and cut-ups were determined on d 42 in addition to meat quality traits and serum lipid levels. The different% of dietary fat did not improve growth performance with the interaction of fat level and feed form. But it was highly significant (0.05) with pelleted feed. Also significant higher difference (0.05) was shown in heart% with 2% fat and gizzard% between mash and pelleted feed (1.44 vs. 1.19) and with 2% fat mash feed. Breast% had a higher significant result (0.05) in mash feed. Abdominal fat% at 4% fat was significantly lower than 2 and 6%. Different significance were shown in meat analysis such as DM, fat and ash% with the different levels of fat and forms of feed. No significant differences were shown in blood parameters such as LDL, HDL, Cholesterol and Triglycerides.
