Effect of Exogenous Emulsifier (Lyso-Phospholipid) Supplementation in the Broiler Diet, on the Feed Intake and Growth Performance During Grower Phase

ABSTRACT The objective of this experiment was to investigate the effect of supplementation of an exogenous emulsifier (lyso-phospholipid) in the diet of growing broilers on growth performance and digestibility. A total of 1224 Ross-308 ten day old broiler chicks were distributed into two experimental treatments in such a way that each treatment had twelve replicates with fifty-one birds per replicate. Two experimental diets were formulated with and without emulsifier supplementation according to the nutrition standards of Ross 308. Feed intake and body weight gain of the broilers were measured on a daily basis and feed conversion ratio was also calculated. Nutrient digestibility was determined on the 25th day of age. Analysis of variance under completely randomized design technique was used to analyze the data. Feed intake was increased (p<0.05) by supplementation of emulsifier in the broiler diet on theat 12th, 13th, 21th, 22th, 23th, 24th, and 25th days. Bodyweight gain was not affected (p>0.05) with or without emulsifier supplementation in the broiler diet during 11-25 days of life. However, feed conversion ratio was effected (p<0.05) by emulsifier supplementation and increased from days 21-25th. Nutrient digestibility (dry matter, fat, and crude protein) in the grower phase was decreased (p<0.05) by supplementation of emulsifier in the diet. It can be concluded that supplementation of an exogenous emulsifier in the diet did not show positive effect on the growth performance during the grower phase of broilers, while nutrient digestibility showed adverse effect. Emulsifier supplementation should be tested after 25 days of the life of broilers.
