Effects of lysolecithin supplementation in low-energy diets on growth performance, nutrient digestibility, viscosity and intestinal morphology of broilers

Abstract

1. The study aimed to investigate the effect of lysolecithin supplementation in low-energy diets on growth, nutrient digestibility and intestinal mucosa characteristics of broilers. 2. A total of 800 one-d-old Ross 308 broiler chickens were assigned to 4 dietary treatments consisting of 10 replicates of 20 broilers each. Broilers were fed with 4 different diets: (i) HE: positive control group broilers received a diet with unaltered energy; (ii) LE: negative control group broilers received a diet with lower energy of about 0.27 MJ/kg; (iii) LElys500: broilers received a diet similar to LE supplemented with 500 g/tn lysolecithin product (Lysoforte Booster Dry); and (iv) LElys300: broilers received a diet similar to LE supplemented with 300 g/tn lysolecithin product. The experimental period was 42 d. 3. Body weight gain in treatments HE was higher than LE during the overall experimental period, while LElys500 and LElys300 had intermediate values. Feed conversion ratio was lower in HE and LElys500 than LE group, while the LElys300 had intermediate values. Fat digestibility was improved in both LElys 500 and LElys300 compared to the HE group. Apparent metabolisable energy (AMEn) was higher in HE, LElys500 and LElys300 than LE. Ileum viscosity at 42 d was also affected, being higher in LE group compared to HE. At 28 d mucosal thickness was lower both in LElys500 and LElys300 compared to HE and LE, while no difference occurred between treatment proliferation patterns of duodenal epithelial cells. 4. These findings indicated that lysolecithin supplementation at 500 g/tn of feed in low-energy diets maintained broiler performance. Supplementation of reformulated low-energy diets induced an increase in digesta viscosity. Lysolecithin supplementation resulted in variable alterations in the duodenum mucosal morphology.

Effects of Bile Acids and Lipase Supplementation in Low-Energy Diets on Growth Performance, Fat Digestibility and Meat Quality in Broiler Chickens

“…Although low intake increases digestibility, in present study this mechanism is failed due to high fat content in HE diet (Lammasak et al, 2019). Our findings are similar with the findings of Dairo et al (2010) and Papadopoulos et al (2018) who reported that LE or HE diet did not have any effect on fat digestibility. Similarly, Hu et al (2018) reported that supplementing 0.015% lipase enzyme in LE diet had similar fat digestibility compared to HE diets.…”

Effects of dietary lysolecithin on growth performance, feed utilization, intestinal morphology and metabolic responses of channel catfish (Ictalurus punctatus)

“…According to previous researches, the WG of channel catfish in the same life stage of present study (body weight about 14.77 g) was 161%-489% after the 10 weeks feeding trial (Gatlin & Bai, 1993;Lochmann, Islam, Phillips, Adam, & Everette, 2012;Nguyen & Davis, 2016;Peterson, Booth, & Manning, 2012;Pohlenz et al, 2012;Rábago-Castro, Sanchez, Pérez-Castañeda, & González-González, 2006 (Brautigan et al, 2017;Li et al, 2018Li et al, , 2010Melegy, Khaled, El-Bana, & Abdellatif, 2010;Papadopoulos et al, 2018;Wang et al, 2009). However, Wang et al…”

“…Improvements of feed utilization by dietary lysolecithin supplementation were also found in previous studies in broilers, common carp Cyprinus carpio var. Jian, crucian carp Carassais auratus gibelio and turbot Scophthalmus maximus L. (Brautigan et al, ; Li et al, , ; Melegy, Khaled, El‐Bana, & Abdellatif, ; Papadopoulos et al, ; Wang et al, ). However, Wang et al () and Li et al () reported that dietary addition of lysolecithin resulted in a significant increase in WG of common carp and turbot, respectively.…”

The addition of lysolecithin to broiler diets improves growth performance across fat levels and sources: a meta-analysis of 33 trials

“…Similarly, in reformulated diets, where the aim of supplementation was to recover the reduction in energy between the standard control and the reformulated diet by lysolecithin supplementation, there were no significant effects of treatment on growth performance. 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.…”
