“…The morphological improvements could result from the synergistic effects of emulsifier interactions with the other feed ingredients as opposed to the influence of the emulsifier in isolation [27]. However, variations could also exist with no significant effects of emulsifiers on gut morphology being previously reported [28].…”

Objective: To investigate the physiological effects of exogenous emulsifiers in broiler chickens that were fed tallow-incorporated reduced-energy diets over 35 days.Methods: A total of 256 Ross 308 one-day-old broilers (42.28 ± 0.16 g) were randomly allocated in a 2 × 2 factorial arrangement to 32 pens with eight chicks per cage. Birds were fed one of four dietary treatments as follows: (1) positive control (PCN; energy sufficient diet); (2) negative control (NCN; energy-deficient diet, -100 ME kcal/kg); (3) PCL (PCN plus 0.05% emulsifier) and ( 4) NCL (NCN plus 0.05% emulsifier). Growth performance was evaluated weekly whereas assessments for the carcass traits, digestibility, some blood metabolites, ileal morphology, and meat quality were measured on d 21 and d 35.Results: Birds fed the NCL diet had higher (P < 0.05) body weights, daily gains, daily feed intake, and improved feed efficiency over the entire 35-day period. Improvements (P < 0.05) for the ileal digestibility of crude fat, energy, and dry matter commensurate with longer (P < 0.05) villus heights were also observed with emulsifiers in the NCL and PCL diets. For the carcass measurements, only the liver weights were increased (P< 0.05) with emulsifiers in the supplemented groups. For blood metabolites, higher (P < 0.05) lipase levels were noticed with emulsifiers in the NCL and PCL diets. In addition, marginal reductions (P = 0.076; P= 0.095, respectively) were also noted with emulsifiers for the total cholesterol and triglyceride contents on d 35. Regarding meat quality, breast muscle yellowness was increased (P < 0.05) with emulsifier use in supplemented groups.

“…Furthermore, Cloft et al (2021) reported that the addition of lysolecithin led to the upregulation of carbonic anhydrase VII and interleukin 8‐like 2, which have been also associated with better gut health (see Table 3). However, variations could also exist with no significant effects of emulsifiers on gut morphology being previously reported (Tenório et al, 2022; Wickramasuriya, Cho, et al, 2020).…”

Lipids are a concentrated source of energy with at least twice as much energy as the same amount of carbohydrates and protein. Dietary lipids provide a practical alternative toward increasing the dietary energy density of feeds for high‐performing modern broilers. However, the digestion and absorption of dietary lipids are much more complex than that of the other macronutrients. In addition, young birds are physiologically limited in their capacity to utilise dietary fats and oils effectively. The use of dietary emulsifiers as one of the strategies aimed at improving fat utilisation has been reported to elicit several physiological responses including improved fat digestibility and growth performance. In practical terms, this allows for the incorporation of lipids into lower‐energy diets without compromising broiler performance. Such an approach may potentially lower feed costs and raise revenue gains. The current review revisits lipids and the different roles that they perform in diets and whole‐body metabolism. Additional information on the process of dietary lipid digestion and absorption in poultry; and the physiological limitation brought about by age on lipid utilisation in the avian gastrointestinal tract have been discussed. Subsequently, the physiological responses resulting from the dietary supplementation of exogenous emulsifiers as a strategy for improved lipid utilisation in broiler nutrition are appraised. Suggestions of nascent areas for a better understanding of exogenous emulsifiers have been highlighted.
