“…However, the magnitude of effect on FCR following on top supplementation with lysophospholipids varied between studies, ranging from 8 points in reduction to a 4 point increase vs. an unsupplemented control. This variation was in line with the response seen in other published studies (Chen et al 2019;Jansen et al 2015;Zaefarian et al 2015), and is likely due to the inherent variability in growth response to nutritional additives. Even when assessing much larger datasets than currently presented, models quantifying factors responsible for bird response to phytase enzyme addition could only account for 64-72% of total variation (Rosen 2006).…”

“…These results agree with the findings of Papadopoulos et al (2018), who found that supplementation with 250 g/t LCL in feed could maintain broiler performance in diets that had been reduced by 64.5 kcal ME/kga similar energy reduction to the average applied in this analysis' constituent trials. Chen et al (2019) found that there were significant growth responses to supplemental LCL at 250, 500 and 750 g/t, but the results did not show a clear linear dose response. Surprisingly, and in contrast to previously published literature (Jansen et al 2015) there was no statistical link in this dataset between the type of dietary fat or oil used and the growth response to the addition of lysolecithin.…”

1. This study aimed to quantify the effect of fat type (including unsaturated to saturated ratio (U:S)) and increasing doses of lysolecithin-based products on nutrient availability and growth performance in broiler chickens. 2. A total of 33 separate experimental reports were collated according to predetermined selection criteria to provide 16 performance trials with 'on top' application, and 17 performance trials using reformulated diets, where the contribution of the lysolecithin was taken into account. Data on average daily gain (ADG) and body weight corrected FCR (FCRc) were analysed using the REML method with trial as a random effect. 3. Across the constituent trials, average added dietary fat and oil inclusion was 4.42% (min 1.15%, max 7.00%), with varied U:S ratio (min 0.94, avg 2.50, max 7.65), reflecting diverse fat sources. Overall, neither bird growth performance nor response to lysolecithin supplementation were significantly affected by the U:S ratio of the diets. 4. In performance trials where lysolecithin was added 'on top' of existing formulations, FCRc was significantly reduced by lysolecithin at 250 g/t inclusion compared to the control, with 125 g/t returning an intermediate value. In reformulated trials, FCRc was not significantly affected, suggesting lysolecithin supplementation at 125 and 250 g/t could recover average dietary energy reductions of 57.88 and 73.11 kcal/kg feed, respectively. 5. In conclusion, this study showed that the addition of lysolecithin at levels of 125 g/t and above to broiler diets consistently improved feed efficiency across a range of basal dietary ingredients and fat sources.

“…Additionally, various bio-surfactants have been investigated because of their antibacterial property [ 5 ]. Among bio-surfactants, sophorolipid (SPL) has received much attention in various industrial fields, such as medical, hygiene, and pharmaco-dermatological areas, due to their relatively less toxicity and more biodegradability [ 6 ].…”

Background Gut is a crucial organ for the host’s defense system due to its filtering action of the intestinal membrane from hazardous foreign substances. One strategy to strengthen the gut epithelial barrier function is to upregulate beneficial microflora populations and their metabolites. Sophorolipid (SPL), which is a glycolipid bio-surfactant, could increase beneficial microflora and decrease pathogenic bacteria in the gastrointestinal tract. Therefore, herein, we conducted an experiment with broiler chickens to investigate the fortifying effects of SPL on the host’s gut defense system by modulating the microbiota population. Methods A total of 540 1-day-old chicks (Ross 308) were used, and they were immediately allotted into three treatment groups (6 replications with 30 chicks/pen) according to their initial body weight. The dietary treatments consisted of CON (basal diet), BAM (10 mg/kg bambermycin), and SPL (10 mg/kg SPL). During the experiment, birds freely accessed feed and water, and body weight and feed intake were measured at the end of each phase. On d 35, birds (one bird/pen) were sacrificed to collect jejunum and cecum samples. Results Dietary SPL and BAM supplementation significantly accelerated birds’ growth and also significantly improved feed efficiency compared to CON. Intestinal microbial community was significantly separated by dietary SPL supplementation from that of CON, and dietary SPL supplementation significantly increased Lactobacillus spp. and Akkermansia muciniphila. Moreover, birds fed with dietary SPL also showed the highest concentration of cecal butyrate among all treatment groups. Gut morphological analysis showed that dietary SPL significantly increased villus height, ratio of villus height to crypt depth, goblet cell numbers, and the gene expression levels of claudin-1 and mucin 2. Additionally, dietary SPL significantly decreased the mRNA expression level of pro-inflammatory cytokine, interleukin-6, and increased that of anti-inflammatory cytokine, interleukin-10, compared to other treatments. Conclusions Dietary SPL increases the beneficial bacterial population and butyrate concentration, which leads to a strengthened gut barrier function. In addition, the intestinal inflammation was also downregulated by dietary SPL supplementation.

“…(2017) reported that lysolecithin supplementation (0.05–0.15%) in diets containing soybean oil but with reduced metabolizable energy and essential amino acids showed no difference in both duodenal and jejunal VH. Using a diet containing the animal based fat white grease, Chen et al. (2019) showed that lysolecithin supplementation (0.025–0.075%) increased jejunal VH.…”

Research Note: Intestinal morphology and gene expression changes in broilers supplemented with lysolecithin

Lysolecithin is used as a feed additive to aid fat digestion and absorption in broiler chickens. Previous research has shown that dietary fat source influences how broilers respond to lysolecithin supplementation. Therefore, the objective of this study was to investigate the effect of lysolecithin on a diet formulated with soybean oil on jejunum morphology and expression of selected genes in broiler chickens. Male Cobb 500 chickens were fed a Control diet or the Control diet supplemented with lysolecithin ( TRT ) from day of hatch to day 28. Jejunal samples were collected at day 10 for morphological and gene expression analysis. Feeding the TRT diet did not affect BW, villus height ( VH ), crypt depth ( CD ) or VH/CD ratio compared to Control fed chickens. Differential gene expression in the jejunum was analyzed using a custom microarray. Using a t test, 36 genes were found to be upregulated in TRT fed chickens compared to chickens fed the Control diet. The two most upregulated genes were carbonic anhydrase VII and interleukin 8-like 2, which are associated with healthy intestines. In summary, lysolecithin supplementation in a diet formulated with soybean oil caused no morphological changes but upregulated a number of genes in the jejunum.
