Abstract

Objective
This study aimed to investigated the effects of dietary supplementation with lysolecithins (LPC) on growth performance, nutrient digestibility, blood profiles, immunity, and liver health in broiler chickens.
Methods
A cohort of 240 one-day-old male Arbor Acres broilers of comparable weight was divided into four treatment groups, each comprising six replicates of 10 birds. The groups were defined as follows: positive control with recommended metabolizable energy (PC+ME), negative control with 90 kcal/kg reduced ME (NC+ME), PC supplemented with 300 mg/kg LPC (PC+LPC), and NC supplemented with 300 mg/kg LPC (NC+LPC).
Results
LPC supplementation led to a statistically significant reduction in the feed conversion ratio (P = 0.05) and a decrease in the proportion of abdominal fat and the liver (P<0.05). Digestibility of dry matter was also enhanced (P < 0.05). Malondialdehyde concentrations in the liver were significantly reduced by LPC (P<0.01), with a noteworthy interaction between energy levels and LPC affecting this reduction (P<0.05). Serum levels of interleukin-6 were reduced on day 21, and both endotoxin and interleukin-6 levels were lower on day 42. Notably, a significant interaction was observed between the energy levels and LPC on relative liver weight and endotoxin concentrations in the serum (P<0.05).
Conclusion
The study concluded that LPC positively affects growth performance, nutrient digestibility, immune response, and antioxidative capacity in broiler chickens, affirming its value as a beneficial feed additive in poultry nutrition.
