“…Asteraceae plants have already been studied due to their abundant bioactive substances, which are conducive to improve the performance of poultry [11][12][13]. Previous results revealed that dietary supplementation with 1 g/ kg dandelion leaf powder increased the total weight gain for 1-21 day and 1-35 day, and decreased the cumulative feed conversion factor for 1-21 day [14]. Yan et al (2012) [15] found that dietary inclusion with 1 g/kg dandelion increased the ADG and the G:F ratio.…”

Background Dandelion has a great potential to be used as feed additive. Using microbial fermentation technology to degrade cell walls is conducive to enable better release of bioactive compounds of dandelion. This study intended to explore the effect of fermented dandelion (FD) on production performance, meat quality, immune function, and intestinal microbiota of broiler chickens. One-hundred and twenty 1-day-old male Arbor Acres broiler chickens were randomly allotted into three treatments: CON (basal diet, control), LFD and HFD (basal diet with 500 and 1000 mg/kg FD, respectively), with five replicates of eight birds each. The experiment lasted for 42 days. Results The results showed that birds in HFD group had increased ADG during 1–21 days (P < 0.05). On day 21, the bursa of Fabricius index of birds in LFD group was higher (P < 0.05), while the serum contents of IFN-γ and TNF-ɑ were lower in HFD group (P < 0.05). FD supplementation decreased the observed_species, shannon, chao1 and ace indexes (P < 0.05) as well as the abundance of Bacteroidota, Bacteroides, and Alistipes (P < 0.05). Birds in HFD group had higher abundance of Firmicutes and lower abundance of Verrucomicrobiota (P < 0.05). LFD group had lower abundance of unidentified_bacteria (P < 0.05). On day 42, the abdominal fat yield of HFD group was decreased (P < 0.05). Birds in LFD group had lower L* and b* values of breast muscle (P < 0.05), while higher spleen index. The CAT activities of breast muscle of FD groups were higher (P < 0.05). Conclusion In summary, dietary FD supplementation at 1000 mg/kg improved production performance and immune function and modulated microbiota composition in ileum of broiler chickens. FD can be supplemented in the diet to enhance performance and health of broiler chickens, of which 1000 mg/kg FD is more effective.

“…Thus, higher TP levels may indicate less damage to the intestinal mucosa from infection, leading to better nutrient absorption or reduced leakage into the intestinal lumen. Previous studies on chickens have demonstrated that dandelion reduces the concentrations of TG, TC, and GLU in the blood of uninfected chickens [ 24 , 26 ]. However, such hypoglycemic and hypocholesterolemic effects at 5 d PI were not observed in the current study.…”

“…Among its antioxidant and anti-inflammatory phenolic compounds, derivatives of hydroxycinnamic acid—specifically chicoric acid, chlorogenic acid, and caffeic acid—have been found in the highest concentrations [ 22 , 23 ]. Various studies have reported dandelions’ ability to improve growth performance in poultry [ 21 , 24 , 25 , 26 ]. A recent study demonstrated that dandelion enhances feed efficiency in broilers by enhancing intestinal barrier function, decreasing proinflammatory cytokines, and optimizing the composition of the intestinal microbiota [ 25 ].…”

A total of 160 Ross 308 male chickens were used in a 2 × 2 factorial design to examine the effects of anticoccidial vaccination (ACV; lack or 1× dose recommended by the manufacturer) and dietary supplementation with Taraxacum officinale (dandelion) extract (DE; with or without) on growth performance, immunity, biochemical parameters, and intestinal morphology in broiler chickens challenged with Eimeria spp. At 20 days of age, all birds were challenged with a 25× dose of ACV, including Eimeria acervulina, E. maxima, E. mitis, and E. tenella. No interaction between ACV and DE was observed in terms of growth performance. Vaccinated birds showed increased feed intake (FI) and feed conversion ratio (FCR) during the 11–20 day period. Meanwhile, DE supplementation led to decreased FI and body weight gain (BWG) during the 1–10 day period. ACV effectively induced immunity against Eimeria, as evidenced by reduced oocyst shedding and less intestinal lesions, decreased levels of pro-inflammatory interleukin-6, and improved BWG during both the post infection (PI) period (21–35 days) and the entire growth period. DE supplementation lowered FCR and increased BWG during the 35–42 day period, increased the concentration of butyric acid in the cecal digesta, and lowered oocyst shedding PI. In vaccinated birds, DE elevated levels of plasma total protein and immunoglobulin M, and influenced tight junction proteins zonula occludens-1 and claudin-3, indicating a more robust epithelial barrier. DE also lowered alanine aminotransferase activity in unvaccinated birds. Both ACV and DE independently improved intestinal morphology in the jejunum, decreasing crypt depth and increasing the villus height-to-crypt ratio. These findings suggest that both ACV and DE could be effective strategies for managing coccidiosis in broiler chickens.

“…Dietary supplementation with dandelion enhanced the growth performance of pigs [ 13 ] and olden pompano Trachinotus ovatus [ 14 , 15 ]. Noor et al (2021) reported that dietary supplementation of 2.0 g/kg dandelion leaf powder decreased the feed consumption and feed conversion factor of broiler chickens [ 17 ]. In consistent with previous studies, the present study showed that adding dandelion to the diet decreased ADFI and F/G ratio of broilers, and that dandelion supplementation at low dosage in particular, improved broiler performance more than high dosage and CTC.…”

Background Dandelion is becoming an exploitable alternative to the widely prohibited antibiotics in the poultry production. This research aimed to investigate the effects of dandelion on the growth performance and intestinal barrier function of broiler chickens maintained under standard condition of management. One-hundred and sixty 1-day-old Arbor Acres (AA) male broiler chickens were randomly divided into four groups, with five replicates of eight birds each. The birds were fed a basal diet supplemented without (control group, [CON]) or with 500 (low dose [LD]) or 1000 (high dose [HD]) mg/kg dandelion or with 250 mg/kg chlortetracycline 20% premix (CTC) for 42 days, including the starter phase (d 1 to 21) and the grower phase (d 22 to 42). Body weight (BW) of each bird and feed consumption of each replicate were measured at d 21 and d 42. The ileal tissues were collected on day 21 and 42 to determine expression of genes coding for tight junction protein and mucin as well as ELISA analysis for immune factor. The ileal digesta was collected for microbiota and short chain fatty acids analysis. Results Compared with CON group, during day 1–21, the average daily feed intake (ADFI) and feed/gain ratio (F/G) of LD group were lower (P < 0.05); during day 22–42, the F/G of LD and CTC group tended to be lower (P = 0.07); during the overall phase, the ADFI of HD and CTC groups were decreased (P < 0.05), and the F/G of dandelion and CTC groups tended to be decreased (P = 0.07). On day 21, the relative mRNA expression of claudin, occludin-1 and mucin1 in dandelion groups were up-regulated (P < 0.05), and the ZO-1 mRNA expression in CTC group was increased (P < 0.05); on day 42, the claudin and mucin1 transcripts in LD group and ZO-1 transcripts in HD and CTC group were up-regulated (P < 0.05), while the occludin-1 and mucin1 transcripts in CTC group was significantly down-regulated (P < 0.05). In addition, the contents of TNF-α in dandelion groups were lower than that in CTC group (P < 0.05). In the analysis of ileal microbiota, on day 21, decreased α-diversity was observed in HD and CTC groups (P < 0.05). Meanwhile, on day 21, the relative abundance of Firmicutes in dandelion groups tended to be higher (P = 0.09), the relative abundance of Lactobacillus in LD and CTC group were increased (P < 0.05), while Bacteroidete, Bacteroides, and Alistipes relative abundance in dandelion and CTC groups were decreased (P < 0.05). On day 42, the Actinobacteriota relative abundance in CTC group tended to be higher (P = 0.05), and Lysinibacillus relative abundance of CTC group was higher (P = 0.02). Compared with CON group, on day 21, the propionic acid and butyric acid content in CTC group were higher, the butyric acid content in HD group was lower (P < 0.10). Conclusion In summary, dietary dandelion supplementation at 500 mg/kg of diet enhanced growth performance of broilers by improving the intestinal barrier function. Dandelion can be supplemented in the diet as an antibiotics alternative to enhance production in poultry industry.
