Two studies were conducted to determine the effects of dietary supplementation of lysophospholipids (LPL), and different lipid sources (SBO, CO, and PO) on the growth performance, carcass characteristics, nutrient digestibility, and blood lipid profiles in broilers. In Study 1, a total of 384 one-day-old male, Ross 308 broilers were randomly allotted to one of the six dietary treatments with 8 replicates each using RCBD. Results showed that broilers fed diets with CO had higher MOFC and better (P0.05) FCR during the booster phase (d 0 to 10). LPL supplementation improved (P0.05) the FCR of broilers when PO is the lipid source in the diet then resulted to better MOFC. LPL also improved (P0.05) the dressed yield (%), regardless of fat source, and influenced the spleen (%) if CO is the lipid in the diet. Increased (P0.05) TG in the blood is observed as an effect of LPL. Lipid source had no significant effect on the blood lipid profiles of broilers (P0.05). In Study 2, 30 broilers were randomly allotted and individually placed in metabolic cages to evaluate the nutrient digestibility and daily energy balance of broilers for 11 days. Results showed that ATTD of fat in the diet was higher (P0.05) with diets containing CO without LPL and an effect of rancid SBO resulted to decreased (P0.05) DM and GE intake and improved (P0.05) ATTD of fiber. The findings suggest that CO is more cost-efficient as a dietary fat source, and LPL supplementation is more efficient for diets containing PO.
