“…The increased abundance of Lactobacilli following a decrease in Romboutsia may be due to polysaccharides in YC being used by Lactobacilli to produce a large number of short-chain fatty acids and lactic acid, which reduce intestinal pH. Another reason may be the increased shedding of Romboutsia due to the occupied effect of Lactobacilli ( Baldwin et al, 2018 ; Qiao et al, 2018 ; Bunte et al, 2020 ).…”

This study aimed to investigate the effects of dietary yeast culture (YC) supplementation on egg production, egg quality, reproductive performance, immune functions, antioxidant capacity, and intestinal microbial structure of aged hens. A total of 224 Hy-Line Brown layers (54 weeks old) were randomly assigned to two dietary treatments. The control group was fed a basal diet and the YC group was supplemented with YC at 2.0 g/kg of their diet. Each group had seven replicates with 16 hens each. The study was conducted over a period of 8 weeks. Results indicated that YC addition had no significant effect on laying performance. However, it significantly improved egg quality and hatching rate, enhanced ileum crude fat digestibility, increased the serum parameters of lysozyme (LZM) and total antioxidation capacity (T-AOC) (P < 0.05), and reduced serum aspartate aminotransferase (AST) levels (P < 0.05). Using 16S rRNA analysis, we found that addition of YC significantly altered ileum microbial composition. Linear discriminant analysis of effect size (LEfSe) showed significant enrichment of Bacilli and Lactobacilli in the YC group. PICRUSt analysis of the ileal microbiota found that glutathione metabolism, ubiquinone, and other terpenoid-quinone biosynthesis and lipopolysaccharide biosynthesis protein pathways were highly enriched in the YC group compared with the basal diet group. In summary, the addition of YC can improve egg quality, immune functions, antioxidant capacity, reproduction efficiency, and digestive absorption by increasing the abundance of Lactobacilli and Bacilli. Furthermore, it also improves the biosynthesis of lipopolysaccharide proteins, glutathione metabolism, and the synthesis of ubiquinone and other terpenoid-quinone metabolic pathways.

“…However, with regard to the different parts of the gastrointestinal tract, fermentation might have had influences on the small intestine’s microbiota, which can no longer be seen in faeces. When offered a non-fermented liquid feed compared to a fully fermented liquid feed to pigs, significant effects on the pig microbiota of the small intestine were seen in the experiments of Bunte et al [ 23 ], while colonic and faecal microbiota seemed to remain unaffected.…”

“…Rye, popular in human nutrition, shows the highest fermentation rate and extent as well as high butyric acid formation in an in vitro colon model compared to wheat and oat, probably due to its high fructan and water-extractable arabinoxylan content [ 22 ]. Finally, fermentation of feed is of special interest because of its potential to have probiotic and prebiotic-like impacts on intestinal and faecal bacterial composition, as already observed in pigs [ 23 ].…”

Faecal Microbiota of Dogs Offered a Vegetarian Diet with or without the Supplementation of Feather Meal and either Cornmeal, Rye or Fermented Rye: A Preliminary Study

Anthropomorphism of dogs has affected feeding and the choice of components present in diets for dogs. Conflicting trends are present: raw or vegetarian appear more prevalent. Animal-derived proteins seem to have unfavourable impacts on intestinal microflora by decreasing the presence of Bacteroidetes. This preliminary study evaluates whether effects of diets with animal proteins on intestinal microbiota can be compensated by the addition of certain carbohydrates to dog diet. Eight female beagles were included in a cross-over study and fed a vegetarian diet or the same diet supplemented with feather meal (2.7%) and either 20% of cornmeal, fermented or non-fermented rye (moisture content of the diets about 42%). A 16S rRNA gene amplification was performed within the hypervariable region V4 on faecal samples and sequenced with the Illumina MiSeq platform. The Firmicutes/Bacteroidetes ratio tended to shift to the advantage of Firmicutes when feather meal and cornmeal were added (Firmicutes/Bacteroidetes ratio of 5.12 compared to 2.47 when offered the vegetarian diet) and tended to switch back to the advantage of Bacteroidetes if rye: fermented (2.17) or not (1.03) was added. The addition of rye might have the potential to compensate possible unfavourable effects of diets with animal proteins on intestinal microbiota of dogs.

“…For FLC diets the cereal component of the diet (including ENZ for ENZ+) was mixed with water, inoculated with Sweetsile ® , and fermented for 52 h, with daily backslopping. The balancer fraction was added to the fermented cereal and mixed for 5 min before feed out [33] Fresh Fresh LF was mixed with water immediately before feeding, while for FLF the whole diet was fermented with Lactobacillus plantarum, Pediococcus pentosaceus and Lactococcus lactis for 24 h. The experimental period lasted 28 days [100] PFLF g (with non-fermented course cereals) vs. fresh LF For PFLF, rapeseed extracted meal and part of the rye (60% of the whole diet) were fermented as above while the remaining cereal components were not fermented. Phytases and the mineral supplement were added after fermentation.…”

There is evidence that spontaneous fermentation frequently occurs in liquid pig feed that is intended to be delivered as fresh liquid feed, often with a resultant deterioration in the microbial and nutritional quality of the feed, which can negatively affect pig health and growth. Strategies including controlled fermentation with microbial inoculants, pre-fermentation or soaking of the cereal fraction of the diet, enzyme supplementation and dietary acidification have been employed to inhibit pathogens and prevent deterioration of feed nutritional quality, with promising results obtained in many cases. This review evaluates the impact of these strategies on the microbial quality of liquid feed and discusses how they can be further improved. It also investigates if/how these strategies impact the pig gut microbiota and growth performance of liquid-fed pigs. Finally, we review liquid feed system sanitisation practices, which are highly variable from farm to farm and discuss the impact of these practices and whether they are beneficial or detrimental to liquid feed microbial quality. Overall, we provide a comprehensive review of the current state of knowledge on liquid feed for pigs, focusing on factors affecting microbial quality and strategies for its optimisation, as well as its impact on the pig gut microbiome.
