Abstract:

This study was conducted to determine the growth performance, carcass traits and lipid profile of broiler chicks fed with an exogenous emulsifier and increasing levels of energy provided by palm oil. A total of 640 one-day-old male Ross 308^® broilers were placed for 42 days, and were assigned to four dietary treatments, with 8 replicates per treatment and 20 birds per replicate according to completely randomized design. The treatments consisted of three increasing levels of metabolizable energy (ME) of 12.13 MJ/kg (starter) and 12.80 MJ/kg (finisher) (T1); 12.38 MJ/kg (starter) and 13.05 MJ/kg (finisher) (T2); 12.64 MJ/kg (starter) and 13.51 MJ/kg (finisher) (T3); and the supplementation of an exogenous emulsifier to liquid dose of 0.5 L/t on diets (T4) with the same ingredients and contributions that the T1. Mortality and feed intake were not affected (P>0.05) by the experimental diets in any experimental period. Meanwhile, the treatments did not influence on the carcass, breast and abdominal fat weight and yield, breast meat color and lipid profile (P>0.05). However, the T3 increased the body weight and liver weight and yield and decreased feed conversion ratio with significant differences (P>0.05) between treatments. Thus, the exogenous emulsifier had no effect on productive indicators and lipid profile in broiler and showed similar results to T1 and T2; the T3 with more ME and oil palm showed the results best.
