LYSOFORTE® Booster Dry vs. Commercial Synthetic Emulsifier

Introduction
A field trial was carried out in a commercial broiler farm of a poultry integrator to compare the efficacy of LYSOFORTE Booster Dry, and a commercial synthetic emulsifier. LYSOFORTE is a natural biosurfactant based on an optimized combination of lysophospholipids, while the commercial synthetic emulsifier is based on Glyceryl Polyethylene glycol Ricinolate (E484). The performance of the broiler chickens were recorded. Approximately 88 600 chickens were (Ross 308 one day old) in the trial  with an average trial period of 34.4 days. The chickens were assigned to two treatments: VE: animals fed with standard reformulated diets (-45 kcal/kg of feed AME) + 500 g/ton of the commercial synthetic emulsifier; LYSOFORTE: animals fed with standard reformulated diets (-45 kcal/kg of feed AME) + 500 g/ton of LYSOFORTE Booster Dry. Diets were based on wheat, corn, triticale, soybean meal, full fat soya, whole rapeseed, corn DDGS and animal fat.  Mortality, final BW, FCR and EPEF were recorded.

Results

 

*Adjusted FCR at 2 kg of final BW calculated according to Ross Broiler Management Handbook 2014

Final BW was 90 g higher for broilers fed with the LYSOFORTE Booster Dry supplemented diet compared to broilers fed diets supplemented with the synthetic emulsifier. FCR was still 20 g better for LYSOFORTE compared to VE

despite of the higher final BW. Adjusted FCR at 2 kg of BW revealed a difference of 40 g in favor of LYSOFORTE (see figure 1). 

Additionally the customer reported that since they started using LYSOFORTE Booster Dry, they recorded an increased average meat yield of 6 g per broiler at slaughter at one slaughter house.  That means an annual extra  profit of €404.400. Considering that the customer owns two more slaughterhouses with capacities of 90 000 and 110 000 broilers/day, LYSOFORTE Booster Dry application   might lead to a total extra profit of more than €1 million.

These results confirmed the superior efficacy of LYSOFORTE Booster Dry compared to the commercial synthetic emulsifier on broiler performance. It is worth mentioning that the results shown above reflect top performing conditions -  EPEF close to 400. This shows LYSOFORTE Booster Dry is extremely effective in high performance conditions.

This superiority has been confirmed as well using an “in vitro” digestion model to mimic the conditions of lipid digestion process in poultry. Main findings on lipid emulsification (Figure 2), lipid hydrolysis (Figure 3) and lipid absorption (Figure 4) are described below. 

Conclusion
The results show the superiority of LYSOFORTE Booster Dry compared to synthetic emulsifiers in broiler performance, leading to higher final BW and better FCR, which is finally translated into a higher EPEF. The customer’s testimony confirmed that LYSOFORTE Booster improved meat percentage in broiler carcasses at the slaughterhouse causing  great positive economic impact. The superior results in terms of lipid emulsification, lipid hydrolysis and lipid absorption obtained with the “in vitro” lipid digestion model supports superiority of LYSOFORTE Booster Dry. (higher final BW, better FCR and higher meat yield) that is obtained in field conditions compared to synthetic emulsifiers with top performing broilers.
