Effect of tallow and crude soybean oil with or without l-carnitine on performance of broiler chicken

The present experiment was conducted to study the effect tallow (3.28%) and crude soybean oil (2.87%) with or without Lcarnitine (100mg/Kg) supplementation on the performance of male broiler chicks. A total of 160 day old male broiler chicks were divided into 4 treatments with eight replicates of five birds each. Before the feed formulation, the lipid profile of the tallow (TAL) and crude soybean oil (CSBO) were analyzed by Agilent technologies 6890N Gas chromatography. The UFA: SFA ratios were found to be 5.37 and 0.77 for CSBO and TAL, respectively. Body weight gain was significantly (P 0.05) effect on feed intake during the overall period. Whereas, supplementation of L-carnitine significantly (P<0.05) lowered feed intake during the overall period. Interaction effect was significant during the finisher and the overall period. FCR was significantly (P<0.05) better for CSBO during the starter and the overall periods. Inclusion of carnitine significantly (P<0.05) improved FCR during all the phases.
