Possibility of use of residue from the purification of soybean oil (soybean gum) in commercial poultry feeding: A review

Brazil stands out among the largest producers of broilers and soybeans in the world. The amount of soy produced and processed in the country means that any residue from the process is considered to have a great environmental impact. Therefore, an alternative to using soy gum, which is a by-product from oil purification, is necessary. Soy gum is a complex of phosphatides that can function as an emulsifier in animal diets, with poultry farming being a production chain capable of absorbing the amount of soy gum production in the country. Due to the high concentration of lecithin present in soy gum, added to preliminary studies that used it as an alternative emulsifying product in the diet, we can infer that soy gum is indeed a product with emulsifying potential and can be used to facilitate the digestion of lipids by broiler chickens and may even be a viable alternative for the initial phases in which the birds have digestion and absorption interference due to the digestive system not being completely developed.
