“…In contrast to this study, Fonseca et al (10) used a soy lecithin emulsifier and obtained a better yield of prime cuts compared to the control treatment. However, similar to the present research, Kamran et al (11) studied emulsifier levels in different lipid sources in the diet of broilers and observed no influence on carcass yield despite the obtained differences in productive performance.…”

This study aimed to evaluate the effects of adding levels of emulsifier based on soy lecithin and enzymatic complex (xylanase, β-glucanase, galactosidase, protease, amylase, and β-mannanase) on the basal diet during the raising of free-range broiler chickens. The experimental design was completely randomized, with five treatments and six replications. Treatments were: T1: control diet, without enzymatic complex and emulsifier; T2: 0.2 kg t-1 of enzymatic complex; T3: 0.5 kg t-1 of emulsifier; T4: 0.2 kg t-1 of enzymatic complex + 0.5 kg t-1 of emulsifier; and T5: 0.3 kg t-1 of enzymatic complex + 1 kg t-1 of emulsifier. Performance data were collected every 14 days, and the animals were euthanized at 70 days to obtain carcass, breast, drumstick, and thigh yield and intestine collection for pH analysis and morphometry. The periods from 1 to 56 and 1 to 70 days showed a difference (P<0.05) in the parameters of zootechnical performance, the feed intake was lower in T4 and T5, and weight gain was better in T1, T2, T3, and T4. Feed conversion was better in T1, T2, and T4. No difference (P>0.05) was observed for poultry livability, carcass yield, viscera, and pH of duodenum and cecum. A difference was found for intestinal morphometry (P<0.05), and T5 showed the best villus/crypt ratio. The level with 0.3 kg t-1 of enzymatic complex and 1 kg t-1 of emulsifier indicated a better relationship between villi and crypts. However, the level with 0.2 kg t-1 of enzymatic complex and 0.5 kg t-1 of emulsifier added to the commercial diet led to benefits such as decreased feed intake, without affecting weight gain, thus inducing a good feed conversion.

A 56-day feeding trial was conducted in a flow-through seawater system to investigate the effects of lysophosphatidylcholine (LPC) on growth performance and lipid metabolism of turbot. Four experimental diets were prepared, differing only in the LPC supplementation, namely, 0 (LPC-0, control), 0.1 (LPC-0.1), 0.25 (LPC-0.25), and 0.5% (LPC-0.5) of dry matter. Each diet was randomly fed to triplicate tanks. LPC-0.1 and LPC-0.25 led to significantly higher weight gain than the control diet, and the highest weight gain was observed in LPC-0.1. Compared to the control group, the LPC-supplemented groups had higher survival and lower hepatosomatic index and viscerosomatic index. LPC-0.25 led to significantly lower contents of crude lipid and ash in whole fish. Dietary LPC supplementation led to a basic decrease in the lipid metabolism-related biochemical parameters in serum but had only very minor influence on the fatty acid composition in the liver and subcutaneous tissue around the fin (STF). High LPC levels upregulated the mRNA expression of BSAL and ApoEα in both the liver and STF. In conclusion, dietary LPC supplementation (0.1-0.25%) enhanced the growth, lowered the lipid accumulation in juvenile turbot, and significantly regulated the lipid metabolism. However, it seldom influenced the fatty acid composition.

“…Emulsifier (0.035%) in broilers fed diet containing different oil levels (1, 2 and 3%) had greater heart weight (8.51 vs 7.01 g) than control group (Abbas et al, 2016). Kamran et al (2020) used different levels (0, 0.025, 0.035, 0.045%) of PGPR in broilers diet reared on three oil sources (poultry fat, soy oil and oxidized soy oil) and reported that lightness, redness, yellowness and pH were not influenced by different dietary treatments. Broilers diet supplemented with multi-enzyme and emulsifier along with low density diet had no effect on breast yield with high density diet (Cho et al, 2012).…”

“…Addition of 0.1% emulsifier in broilers diet had increased weight gain and FCR during the period of 0 to 19 days (An et al, 2020). Kamran et al (2020) used different levels (0, 0.025, 0.035, 0.045%) of polyglycerol polyricinoleate (PGPR) in broilers diet on three oil sources (poultry fat, soy oil and oxidized soy oil) and concluded that use of PGPR in soy oil based diet had improved FCR than control diet in broilers. Use of 0.05% lysophospholipid in broilers diet had improved feed intake and FCR (Chen et al, 2019).…”

Commercial broilers have a short production cycle and a high requirement for energy (3000 kcal/kg in starter phase and 3200 kcal/kg in finisher phase). Therefore, the need to add energy rich lipids to their diet is inevitable. Digestibility of fat depends on its multiple properties: chain length, the composition of fatty acids, ratio of saturated/unsaturated fatty acids and free fatty acids. The high cost of vegetable oils and less availability due to their consumption in human diet are the main reasons for searching cheaper alternative fat sources. Animal oils like poultry and fish oil are the by-product of rendering plants and after refining, they are used in poultry diets as an energy source. Due to presence of impurities and free fatty acids, the digestibility of animal fat is less. There is a limited amount of bile acids and lipase available during early age and when birds are reared on high energy diet (finisher phase). Supplementation of emusifier or lipase in broilers diet increase fat utilisation. Emulsifiers increase fat digestibility by increasing active surface area of lipid droplets. Lysolecithin and Lysophospholipids are produced from hydrolyses of lecithin and phospholipids by phopholipase A2. The bile acids mainly compose of cholic acid, hyodeoxycholic acid and chenodeoxycholic acid and have strong emulsification properties. Triacylglyceryl acylase (lipase) is an enzyme involved in catalysis and the hydrolysis of lipids. It can be concluded that use of emulsifier and lipase in broilers diet improves growth performance, nutrient digestibility and intestinal histology in broilers.
