Abstract
Background: The production and secretion of lipase and bile salt are restricted particularly in young chicks, resulting in a feeble metabolism of lipids as well as oils. Addition of exogenous lysolecithin in the poultry rations may be incorporated as better option to control such constraint.
Methods: In total, 120 day-old Hubbard broiler chickens assigned at random to four nutritional treatments for period of 42d trial. The broiler’s rations (0-28d and 29-42d) were added with 0, 0.050, 0.075 and 0.10% exogenous emulsifier with1.0% soybean oil. The data relating performance, carcass traits, fat digestibility and blood fat profiles in chickens was obtained during experiment.
Results: During days 1-21 and 1-42, chickens fed diets with high levels (0.075 or 0.100%) of emulsifier with soybean oil resulted significantly (p<0.05) better weight gain and feed: gain ratio than without emulsifier. The broilers on emulsifier diets fed substantially (p<0.05) less feed intake and considerable (p<0.05) decreased feed: gain ratio as compared to without emulsifier at 1-21d. The relative weight of the breast or leg meat yield, and liver significantly (p<0.05) increased in broilers given exogenous emulsifier rations. On day 21 and 42, the digestibility of fat in birds offered with emulsifier diets were substantially (p<0.05) increased than that of control group. Lipid profile was not influenced by exogenous emulsifier supplementation in broiler’s diet.
Conclusion: This study envisaged that exogenous emulsifier supplementation (0.05 to 0.10%) in broiler’s diet improved the performance, meat yield and fat digestibility without affecting on cholesterol profile in broilers.
