Adding a mixture of exogenous emulsifiers to low-energy poultry diets improves bird growth and feed conversion efficiency. Broilers were tested across three feeding regimes: a standard basal diet, an energy-reduced diet lowered by 50 kcal/kg, and an energy-reduced diet supplemented with 500 grams per tonne of an emulsifier blend containing phosphatidyl choline, lysophosphatidyl choline, and polyethylene glycol ricinoleate. While feed consumption remained unaffected, birds receiving the supplemented lower-energy feed showed notable gains in weight and better feed conversion ratios compared to those on unsupplemented lower-energy feed. The additive restored and enhanced protein and lipid utilisation, which otherwise dropped under lower-energy feeding. Supplementation alongside dietary energy reduction also decreased liver lipid peroxidation indicators and muscle palmitic acid levels, while boosting plasma cholesterol, protein, and globulin levels without altering key muscle fatty acids.
Feed makes up a substantial portion of the cost of poultry production. Finding dietary formulations that allow birds to thrive on lower-energy feeds without sacrificing growth or feed efficiency helps poultry producers lower production expenses. This approach demonstrates that blending specific emulsifiers supports healthy fat and protein absorption, enabling more cost-effective poultry farming without harming animal growth performance.
This applied and tested research provides a direct formulation strategy for animal feed manufacturers and commercial poultry producers. By incorporating an emulsifier blend of phosphatidyl choline, lysophosphatidyl choline, and polyethylene glycol ricinoleate into low-energy broiler feeds, producers can cut dietary energy levels without losing growth performance. Because it tests specific inclusion rates in birds, the approach is ready for validation in larger-scale commercial feed-mill trials to reduce overall feed production costs.

To investigate the influence of emulsifiers on broilers fed low-energy diets, the birds were distributed into three sets-the control was fed the basal diet, the second group was fed diets 50 kcal/kg less than control, and the third group was fed diets 50 kcal/kg less than control and supplemented with 500 g/ton of emulsifiers. The used mixture of exogenous emulsifiers contains phosphatidyl choline, lysophosphatidyl choline, and polyethylene glycol ricinoleate. Although the feed intake was not meaningfully affected by dietary low-energy level with emulsifier inclusion (<i>P</i> = 0.42), the weight gain and FCR were clearly enhanced (<i>P</i> = 0.005 and <i>P</i> = 0.044, respectively). Protein and lipids utilization were decreased by reducing energy level, but they were increased by emulsifier supplementation (<i>P</i> = 0.022 and <i>P</i> = 0.011, respectively). Liver thiobarbituric acid-reactive substances (TBARs) and muscle palmitic acid concentrations were decreased by reducing the energy level and emulsifier's supplementation (<i>P</i> = 0.014 and <i>P</i> = 0.042, respectively). However, muscle total lipids and α-tocopherol, oleic acid, linoleic acid, and α-linolenic acid were not affected by dietary treatments (P > 0.05). Interestingly, the plasma total cholesterol, HDL-cholesterol, total protein, and globulin were decreased in the low-energy group without emulsifier but they were increased by emulsifier supplementation (<i>P</i> = 0.008, <i>P</i> = 0.005, <i>P</i> = 0.037, and <i>P</i> = 0.005, respectively). It could be concluded that the mixture of emulsifier supplementation to low-energy diets enhanced fat utilization and resulted in positive effects on the growth performance, nutrient utilization, lipid peroxidation, and modified plasma lipid profiles in broilers. Getting such benefits in broilers is a necessity to reduce the feed cost and consequently the price of the product, which will lead to improved welfare of mankind.
