- Abstract
The current work was planned to explore the effect of a natural emulsifier (Lysophospholipid) supplementation on growth performance, nutrient digestibility, blood serum, meat quality, carcass characters and economics in broilers. Total research period was divided in starter, grower and finisher phases. A total of 1530, day old Ross-308 chicks were purchased from local hatchery and divided into five treatments in such a way that each treatment had six replicates and each replicate had fifty-one birds. Treatments were (1) diet with emulsifier during overall (0-35 days) period; (2) diet without emulsifier during overall (0-35 days) period; (3) diet with emulsifier during starter (0-10 days) phase only; (4) diet with emulsifier during grower (11-25 days) phase only; (5) diet with emulsifier during finisher (26-35 days) phase only. Results explored that feed intake was not affected (P>0.05) by any dietary treatment in starter and finisher phase. However, feed intake decreased in broilers fed emulsifier supplemented diet during grower phase only (P<0.05). Diets with emulsifier addition throughout life and during finisher phase only showed highest (P<0.05) body weight and better feed conversion ratio. At day 35th % nutrient digestibility (dry matter, crude protein and ether extract) was improved by emulsifier addition in diet (P<0.05). Total cholesterol and triglycerides in blood serum were not affected (P>0.05) by all dietary treatments but glucose was highest (P<0.05) in group fed diet without emulsifier during all phases. Relative organs weight like liver, heart, spleen and gizzard were not affected (P>0.05) by all dietary treatments while, dressing (%) and meat quality were better (P<0.05) by supplementation of emulsifier in diet during finisher phase and overall period. Profit percentage and feed economic efficiency per bird were increased (P<0.05) by emulsifier supplementation throughout the life of broilers and during finisher phase only. Based on the findings of current study it is recommended that natural emulsifier should be added in broilers diet during finisher phase for better growth performance, meat quality, digestibility, economics and dressing percentage.
