This experiment aimed to determine the effects of some elements of lipid metabolism on the development of 120 seven-day-old broilers. Lipid metabolism enhancers L-carnitine and alpha-lipoic acid (ALA) and L-lyso phospholipids (LPL) were used. For the experiment there were six treatment groups: A1, control; A2, addition of lyso-phospholipids (LPL; 250 mL/L drinking water); A3, LPL in drinking water plus oral administration of L-carnitine capsules (5 mg/kg live body weight); A4, LPL in drinking water plus oral administration of alpha-lipoic acid (20 mg/kg live body weight); A5, oral administration of L-carnitine capsules (5 mg/kg live body weight); and A6, oral administration of alpha-lipoic acid capsules (20 mg/kg live body weight). had the highest live body weight and total weight gain( P ≤ 0.05), and the best feed-conversion ratio. However, administration of L-carnitine or ALA alone decreased the weight gain compared to the group A2. In addition, it was observed that combinations of LPL with either L-carnitine or ALA did not induce any statistically significant synergistic effects on growth. Feed-conversion ratios were significantly better in groups A1, A2 and A3 compared with group A6 for the different treatments in the entire experiment. Dressing percentages were similar among treatments, although relative weights of some organs (heart, liver and abdominal fat) differed. In particular, liver weight was higher in the combination of LPL and ALA. In conclusion, the present study revealed that supplementation of rapidly hydrolyzed phospholipids improved broiler performance and the metabolism modulators reduced carcass fat did not significantly alter relative lymphoid organ weights.
