“…Our findings were consistent with previous reports, which showed that dietary supplementation with plant fermentation products was able to affect laying performance and egg quality of layers. Diets supplemented with 1 and 2% fermented phytogenic feed additive could improve laying performance, egg weight, albumen height, and Haugh unit of layers (Park et al, 2016). Yoshida et al (2017) evaluated the effect of the fermented spent mushroom substrate as a dietary additive on egg productivity, suggesting that increased egg production might be related to the protection against stress through the fermentation of waste mushroom beds.…”

Fermented plant product (FPP) is a kind of functional complex containing probiotics and a variety of bioactive substances, which has multiple physiological functions. However, there is no systematic appraisal of FPP as a feed additive for laying hens. This study was conducted to evaluate the utilization of FPP in laying hens. A total of 120 healthy 34-week-old Xianju layers with similar body weight and egg production were randomly allocated into two dietary treatments with four replicates per treatment and 15 birds per replicate for 8 weeks. The dietary treatments included the basal diet without FPP (CON group) and CON diet supplemented with 500 mg/kg of FPP (FPP group). Compared with the CON group, the egg production and egg mass were significantly increased in the FPP group from 38 to 42 and 34 to 42 weeks of age (P < 0.05). Birds fed with the diet containing 500 mg/kg FPP had higher albumen height (P < 0.01) and Haugh unit (P < 0.05) than those of the controls. FPP supplementation significantly increased the villus height (VH) and crypt depth (CD) in the jejunum of laying hens (P < 0.01), as well as the ratio of VH to CD (P < 0.05). The mRNA expression of tight junctions showed that dietary supplementation with FPP significantly increased the expression levels of Occludin (P < 0.01) and ZO-1 (P < 0.05) in jejunum of hens compared to the control group. In addition, dietary supplementation with FPP influenced cecal microbiota of laying hens, which was characterized by the changes in the microbial community composition, including the increased abundances of Firmicutes, Faecalibacterium, Oscillospira, Clostridium, Ruminococcus, and Coprococcus, along with the decreased abundance of Bacteroidetes, Proteobacteria, Phascolarctobacterium, Odoribacter, Desulfovibrio, and Mucispirillum. Spearman's correlation analysis revealed that bacteria such as Faecalibacterium, Ruminococcus, Coprococcus, and Blautia were significantly and positively correlated with the intestinal barrier markers (P < 0.05), with extremely significant correlations between Ruminococcus and ZO-1, and Coprococcus and Occludin (P < 0.01), whereas Desulfovibrio had a negative correlation with the expression of Occludin (P < 0.05). As it can be concluded, FPP supplementation increased the egg production, egg mass, albumen height, and Haugh unit of laying hens, and improved intestinal health by ameliorating intestinal barrier function, which may be partially attributed to the regulation of cecal microbiota. Our findings suggest that FPP has the potential to be used as a feed additive to promote the performance of layers.

“…Diet supplementation with Allium compounds possess beneficial effects: significantly reduces cholesterol levels in the plasma of laying hens [61][62][63][64], in egg contents [63] and even protects against several diseases, including cancer [65]. Supplementation with different phytobiotics such as black cumin seeds or leaves and extracts from the Lamiaceae family (such as peppermint, sage, rosemary, thyme and oregano) increase egg production and egg weight [64,[66][67][68][69][70]. However, results for egg production in laying hens with their diet supplemented by Allium compounds are contradictory.…”

“…Han et al [ 81 ] found that the relative abundance of Lactococcus in the cecum of broilers was positively correlated with body weight. Moreover, supplementation with a phytobiotic in laying hens increased Lactobacillus relative abundance in the cecum and simultaneously improved egg production as well as egg weights [ 68 ]. Most lactic acid bacteria have an intimate relationships with the health of their animal hosts [ 82 ], so these strains have been widely used as probiotics due to their many beneficial properties [ 83 , 84 , 85 ].…”

Phytobiotics (bioactive compounds extracted from plants) are one of the explored alternatives to antibiotics in poultry and livestock due to their antimicrobial activity and its positive effects on gut microbiota and productive properties. In this study, we supplemented a product based on garlic and onion compounds in the diet to laying hens at the beginning of their productive life (from 16 to 20 weeks post-hatching). The experimental group showed a significant increase in the number of eggs laid and in their size, produced in one month compared to the control. This increase in production was accompanied by microbiota changes in the ileum and cecum by means of high throughput sequencing analyses. These bacterial shifts in the ileum were mainly the result of compositional changes in the rare biosphere (unweighted UniFrac), while in the cecum, treatment affected both majority and minority bacterial groups (weighted and unweighted UniFrac). These changes in the microbiota suggest an improvement in food digestibility. The relative abundance of Lactococcus in the ileum and Lactobacillus in the cecum increased significantly in the experimental group. The relative abundance of these bacterial genera are known to have positive effects on the hosts. These results are very promising for the use of these compounds in poultry for short periods.

In this study, the fermentation characteristics of pine needles were investigated for the first time and the possibility of using them as plant-derived feed additives was confirmed. Four types of fermented pine needle were prepared: (1) natural fermentation (CON); (2) Lactobacillus plantarum SK4315 fermentation (LPF); (3) Saccharomyces cerevisiae SK3587 fermentation (SCF); and (4) co-culture fermentation (CCF). Fermentation lasted 48 h, and samples were taken at 4-h intervals until 12 h, then at 24 and 48 h. As analysis items, fermentation characteristics, antibacterial, antioxidant, and enzymatic activities were investigated. As a result, all pine needle cultures were fermented with changes in the number of viable cells and pH. LPF inhibited the growth of the most pathogens, and the activity became stronger with fermentation. Total polyphenol content (TPC) was the highest in the 48 h SCF and LPF samples, ABTS radical scavenging ability and intracellular antioxidant activity were higher in SCF. Enzymatic activities were different depending on each pine needle culture medium and the fermentation time. In summary, all pine needle cultures were normally fermented, and as fermentation progressed, LPF strengthened antibacterial activity and SCF strengthened antioxidant activity. This study confirmed the potential of fermented pine needles as a feed additive, showing an enhancement of biological activity.
