“…However, it has been reported that endogenous emulsifiers alone do not support proper fat digestion in poultry (6). Exogenous emulsifiers are capable of improving fat digestibility and subsequently sustaining or enhancing the growth performance of broiler chickens fed a low-density energy diet (5). With this conviction, studies on different exogenous emulsifiers were conducted to determine their effect on the improvement in the growth performance of broiler chickens (9,21,22).…”

The aim of this study was to investigate the effect of dietary emulsifiers and lipase supplementation on growth performance, blood metabolites, intestinal organ weight, gut morphology, nutrient digestibility, carcass measurements, and meat quality in broiler chickens. A total of 384, 1-day-old Ross 308 broiler chicks were randomly allocated to one of eight dietary treatments arranged in a completely randomized design with 6 replications per treatment and 8 birds per cage. Diets were corn-soybean meal-based and formulated to meet the nutritional requirements for Ross 308 specifications. Beef tallow used as the fat source in all diets. Dietary treatments were as follows, (1) positive control (PC; energy sufficient diet); (2) negative control (NC; energy deficient,−100 ME, kcal/kg); (3) NC+POL (0.1%, Polysorbate-20); (4) NC+CET (0.1%, Ceteth-20); (5) NC+POL+TLL (0.1%, Thermomyces lanuginosus lipase); (6) NC+POL+CRL (0.1%, Candida rugosa lipases); (7) NC+CET+CRL and (8) NC+LL (0.05%, Lysolecithin). Growth performances were measured weekly. One bird per pen was selected and sacrificed to collect blood, ileal digesta, jejunum sample, viscera organ weight, and meat samples on day 21 and 35. Results revealed that birds fed NC+POL+CRL diet had higher (P < 0.05) body weight, weight gain, and the improved (P < 0.05) feed efficiency compared to birds fed other low energy diets, and the effect was more prominent at the grower phase from day 21 to 35. Similarly, higher (P < 0.05) villi height and lower (P < 0.05) crypt depth commensurate with higher (P < 0.05) V:C ratio were observed with the broiler chickens fed NC+POL+CRL diet compared to broiler chickens fed NC diet on day 21 and 35. Moreover, broiler chickens fed NC+POL+CRL diet showed improved fat and energy digestibility compared NC diet counterpart on day 35. This study, therefore indicated that Polysorbate-20 together with Candida rugosa lipases had promising ability to improve growth performance of broiler chickens fed with low energy diet and curtail the growth depression without affecting blood metabolites, carcass, and visceral organs weights.

“…As a remedial measure, the practice of supplementation with exogenous emulsifiers has become commonplace in the feed industry. Synthetic and natural emulsifiers such as milkderived casein, calcium stearoyl-2-lactylate, and sodium stearoyl-2-lactylate have been tested in broiler diets (5)(6)(7).…”

“…However, hampered fat digestion and absorption from feed matrix were reported in young broiler chickens with an incompletely developed digestive tract [3]. As a dietary tool to improve fat utilization, different emulsifiers such as lysolecithin (lecithin), milk derived casein, soylecithin, bile salt, and glycerol polyethylene glycol ricinoleate was tested previously in broiler diets [4]. It may be postulated that exogenous emulsifiers make fat globules more available by optimizing lipase activity and in turn enhancing micelles formation [2,5].…”

Objective: To evaluate calcium stearoyl-2 lactylate (CSL) performance as an exogenous emulsifier together with lipase for broiler diets.Methods: In total, 252 one-day-old Ross 308 broiler chickens were allocated in a completely randomized design to give 6 replications per treatment with 7 birds in each cage. There were six dietary treatments representing a 2×3 factorial arrangement consisted of two energy levels (standard energy [positive control, PC] and –100 kcal/kg of the requirement level [negative control, NC]) and three dietary treatments (without additives [CON], CON+CSL [CSL], and CON+CSL+lipase [CSL-Lipase]). Corn and soybean meal-based experimental diets containing vegetable oil were formulated. Growth performance, blood parameters, visceral organ weights, ileal morphology, nutrient digestibility, and cytokine gene expression were measured.Results: Birds fed a diet including CSL increased (p<0.05) lipase level in blood compared to birds fed a diet including CSL-Lipase on day 21. Similarly, higher (p<0.05) liver weight was observed in birds fed a diet including either CSL or CSL-Lipase on day 21. Birds fed NC diet with CSL improved (p<0.05) nutrient digestibility compared to the NC diet on day 21. However, birds fed a diet supplemented with CSL or CSL-Lipase did not affect (p>0.05) the weight gain, feed efficiency, ileal morphology, and cytokine concentrations during the experiment period, regardless of dietary energy levels.Conclusion: Our results indicated that CSL has a role in improving nutrient digestibility in young birds when supplemented to a corn-soybean meal based broiler diet.

“…Animal fats and vegetable oils are being used in broiler diets to increase energy density and improve growth performance (Leeson and Summers, 2005;Abudabos, 2014;Wu, 2018). However, fat addition negatively affects fat digestibility (Tancharoenrat et al, 2013;Siyal et al, 2017) especially during early broiler age (Tancharoenrat et al, 2013;Ravindran et al, 2016). Immature physiological function of the pancreas in broilers results in less production of bile acids and pancreatic lipase during early ages (Wiseman & Lewis, 1998;Al-Marzooqi & Leeson, 1999;Lilburn & Loeffler, 2015;Classen, 2017), which may leads to poor fat digestibility.…”

“…On the other hand, Hu et al (2018) reported that providing reduced energy diet had decreased (p<0.05) body weight (BW) gain compared to basal energy diet during a period of 14 days, however, it was compensated with the supplementation of 0.015% and 0.03% lipase. According to Wang et al (2017), the supplementation of lipase in broiler diets improved FCR, growth performance and fat digestibility. On the contrary, other researchers reported that lipase supplementation had no effect on nutrient utilization and bird's performance in broiler fed wheatbased diets (Polin et al, 1980;Meng et al, 2004).…”

The aim of this study was to investigate the effect of bile acids and lipase supplementation in low energy (LE) diets on growth, fat digestibility, serum lipid profile and meat quality of broilers. Seven hundred one-day-old broiler chicks were divided into 5 dietary treatments with five replicates of 28 birds each. The five treatments were: i) high energy diet (HE; metabolizable energy (ME) = 3,000 and 3,170 kcal/kg for starter and finisher diet), ii) low energy diet (LE; ME = 2,900 and 3,070 kcal/kg for starter and finisher diet), iii) LE diet supplemented with 300 g/ton bile acids (LEB), iv) LE diet supplemented with 180 g/ton lipase (LEL), v) LE diet supplemented both with bile acids (300 g/ton) and lipase (180 g/ton). The experiment lasted 35 days having starter phase from days 1-21 and finisher phase from days 22-35. Dietary inclusion of both bile acids and lipase in LE diet had no effect (p>0.05) on body weight (BW) gain and feed intake. High energy diet reduced feed intake and BW gain during starter and overall period; however, during finisher phase BW gain was similar in all dietary treatments. Dietary energy level had no effect on feed conversion ratio. Fat digestibility (p>0.05) both in the starter and finisher phase was not affected by the dietary treatments. Concentration of total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol and triglycerides were not affected by the dietary treatments (p>0.05). Meat quality of breast and thigh muscle was unaffected due to the dietary treatments (p>0.05). It is concluded that the supplementation of bile acids alone or in combination with lipase in low-energy diets did not improve broiler performance, fat digestibility, serum lipid profile and meat quality.
