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

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.(AU)

Emulsifier Supplementation Response in Ross 308 Broilers at 1-10 Days

The study was conducted to check the effect of emulsifier supplementation on growth performance of broiler birds on starter phase, from days 1 to 10. In the current study, a total of twelve hundred twenty-four Ross 308 broiler one day old chicks were used. Ross 308 broiler chicks were divided into two groups in such a way that each group had12 replicates, and each replicate had 51 birds. The duration of the current trial was of 10 days. Chicks were fed experimental diets with or without emulsifier supplementation. Daily feed intake, body weight, feed conversion ratio and nutrient digestibility were recorded. Mortality was recorded on a daily basis, and feed intake was also corrected for mortality. Data collected from the experiment was interpreted by using analysis of variance method using SPSSTM under Completely Randomized Design. Results showed that emulsifier supplementation improved (p 0.05) feed intake in broiler birds on the 2nd, 6th, 7th and 9th­ days of the starter phase. Furthermore, emulsifier supplementation (p 0.05) affected the body weight on the 3rd and 10th day of the trial. Emulsifier supplementation also affected (p 0.05) feed conversion ratio on the 10th day of the trial. However, nutrient digestibility was not affected by the supplementation of emulsifier in the diet of broiler chicks. Results showed that emulsifier supplementation should be started on day 10.(AU)
