Influence of Dietary Supplementation of Phospholipids and Lysophospholipids on Performance of Broilers

An experiment was conducted on 144 day old commercial broilers for 42 days to compare the influence of dietary supplementation of phospholipids and lysophospholipids on their performance. Experimental birds, divided equally in four groups, were offered standard broiler mash supplemented with 0.05% phospholipids, 0.05% and 0.1% lysophospholipids in groups T₁, T₂ and T₃, respectively while, group T₀ was offered no supplement. At the end of six weeks, significantly higher body weights were recorded in groups T₂ (1758.92 g) and T₃ (1776.53 g) than other groups. The mean weekly feed conversion ratio was also better in groups T₂ and T₃. Nitrogen retention was the highest in group T₃ (56%) followed by T₂ (53.58%), T₁ (51.45%) and lowest in control (44.41%) group. The serum total cholesterol level was lower in groups T₂ and T₃, while muscle cholesterol was lowest in group T₂. Dressing percentage was higher in group T₁ (63.17%) than in groups T₀ (60.64%), T₂ (61.18%) and T₃ (61.64%). Percent net profit/kg body weight was higher in groups T₂ and T₃ than in other groups.
