Introduction: Modern broiler industry is aiming high towards attaining maximum productivity at sustainable input costs. Feed alone contributes almost 75 percent of the broiler production costs. Increased feed raw material price and efficient utilization of costly nutrients from feed have always been very challenging concerns towards deriving optimum Return On Investment (ROI). Fat whether from oil or other raw material source in broiler diet is an inevitable part. It reduces the passage rate of digesta inside the gut and helps in better absorption of nutrients. Fats also improves palatability of diets and is the highest contributor of energy per unit for the birds. Oils or fats from external source are one of the costliest nutrients for birds. So, optimum bioavailability of nutrients from fat should be ensured for desired economic return.
Bile in poultry gut acts as a primary tool to emulsify and thereby helps digest the fats or oils present in the feed. Studies in poultry shows that fat digestion has limitation in the early mean age of chicks mainly due to limited capacity to recycle the bile salts. On the other hand, natural bile salt production by today’s broiler birds is not enough to fulfil the optimum ether extract digestion and absorption. Prior to absorption of fats in the form of fatty acids, uniform and small micelle formation should have to be ensured in the gut for better absorption of fats because size of the micelles formed also determines their absorption by villi and microvilli. Lysophospholipids can act as a powerful bio surfactant in aqueous medium of gut due to both hydrophilic and lipophilic properties. This in turn can translate more and better spherical micelle formation thereby ensuring better absorption of fats.
LysoforteTM dry from Kemin is a naturally occurring bio surfactant with unique combination of several Lysophospholipids. It has been proven based on several R&D and commercial broiler performance studies that it is extremely effective in enhancing emulsification, fatty acid hydrolysis, micelle formation and absorption of ingested fat compared to other phospholipids or lysophospholipids. Commercially available other products, on the other hand is also supposed to be a potent emulsifier with different combinations of phospholipids and lysophospholipids that may probably improve emulsification and digestion of ingested fat. The objective of the present study was to compare and evaluate the broiler performance by on top application of LysoforteTM and competitor brand products in broiler diets
Trial Objective: The objective of the present study was to evaluate and compare the on top effect of LysoforteTM versus competitor brand upon broiler performance parameters like feed intake, body weight, FCR, Cost of Production (COP) & Return on Investment (ROI).
Trial design: The study was accomplished as per pre-designed protocol and parameters in a well maintained trial facility of Bangladesh in Dec 2015 in Cobb 500 breed broiler birds
|S.No||Trial groups||Dosage||No of birds|
|2.||Brand L||@500g per ton of feed||150|
|3.||LysoforteTM||@500g per ton of feed||150|
The experimental birds were reared upon three phase diets i.e., Starter, Grower and Finisher diets from 0 to 32 days. The diets consisted of mainly Corn, Soybean, Rice Polish and Rice Bran oil and the same quality of all ingredients were used in the manufacturing process of feed with breed recommendation of nutrient specifications. Rearing practices, medication and management followed were same in all the groups. Sanitised and good quality water was provided ad-libitum in all the groups throughout the rearing period. Productivity parameters like Feed Intake, Body Weight, FCR were evaluated in each week of the rearing period and finally on the 32nd day of the trial. Return on investment (ROI) and productivity economics were evaluated for each group after the end of the study.
The end results on 32 days of rearing as
|Feed Intake (Gms)||2830||2835||2873|
|Body Weight (Gms)||1780||1801||1830|
|Cost of Production (BDT)||85.68||85.24||84.41|
Body weight and Feed in take in gms
LysoforteTM group has shown 50 g and 29 g better body weight than control and similar competitor brand respectively
LysoforteTM group has shown 3 points and 1-point improvement in FCR compared to competitor brand and control group respectively.
LysoforteTM group has shown 1.34 % lesser in mortality compared to other groups.
Cost of Production in BDT:
LysoforteTM group has shown 1.27 BDT and 0.83 BDT savings in cost of production of live Kg broiler weight compared to control and competitor brand respectively.
ROI and Economics Calculation:
|No of birds||150||150||150|
|Total feed intake in Kg||2.83||2.835||2.873|
|Final body weight in kg||1.78||1.801||1.83|
|Avg Feed cost in BDT||43||43.28||43.18|
|Chick cost in BDT||30||30||30|

|Total feed consumed in Kg||413.18||413.91||425.20|
|Production cost/kg live weight BDT||85.68||85.24||84.41|

Results showed that both body weight and feed intake was highest in LysoforteTM treated group followed by Brand L group and Control group in descending order. In terms of FCR, LysoforteTM group outperformed both competitor brand and control groups. LysoforteTM group has shown 3 points and 1-point improvement in FCR compared to competitor brand and control group respectively. Mortality trend was lesser in the LysoforteTM treated group than the other groups in same environmental and management conditions. LysoforteTM group has shown 1.27 BDT and 0.83 BDT savings in cost of production of live Kg broiler weight compared to control and competitor brand respectively. In terms of ROI, LysoforteTM group has shown 1:3, but the competitor brand has performed with no returns. This study revealed that addition of LysoforteTM in the diet will helps in fat digestion and absorption, which in turn resulted in better performance than the similar type of competitor brand. This may be correlated with the fact that optimized proportioning and blending of different types of Lysophospholipids in case of LysoforteTM might have aided in better emulsification, micelle formation and absorption of the fats compared to Brand L.
