“…Yeast has been found to be a good alternative to promote ruminant growth and improve gastrointestinal morphology (Xiao et al, 2016), but Candida tropicalis (CT) typically inhabits the bodies of animals (Yahashi et al, 6099 1996). However, compared with Saccharomyces cerevisiae, CT has excellent potential to degrade dietary fiber and activate fiber-decomposing bacteria, thereby increasing the VFA concentration and promoting DM digestibility by affecting the rumen microbiota (Marrero et al, 2015). Therefore, CT and MLF are potential alternatives as additives to improve rumen fermentation and digestion in preweaning calves, which are prone to health problems such as diarrhea (Enríquez et al, 2011).…”

“…Therefore, CT and MLF are potential alternatives as additives to improve rumen fermentation and digestion in preweaning calves, which are prone to health problems such as diarrhea (Enríquez et al, 2011). However, the protective roles of these additives in reducing gastrointestinal issues might differ, such as the antioxidative and anti-inflammatory properties of MLF (Chon et al, 2009) or the documented role of CT in regulating rumen fermentation (Marrero et al, 2015).…”

This study investigated the effects of mulberry (Morus alba L.) leaf flavonoids and Candida tropicalis on the growth, gastrointestinal development, enzyme activity of gastrointestinal digesta, and blood antioxidant function of dairy calves challenged with Escherichia coli O141:K99. A total of 15 Holstein preweaning bull calves (age = 28 d; body weight = 51 ± 3.9 kg, mean ± standard deviation) were randomly divided into 3 homogeneous groups with no supplementation (control, CON), Candida tropicalis added at 1 g/calf per day (CT), and mulberry leaf flavonoids added at 3 g/calf per day (MLF). The feed efficiency was greater in calves fed MLF than in CON either before or after the E. coli challenge test. The fecal score increased after E. coli challenge, but it was greater in the CON group than in the CT treatment and in the MLF group at d 1, 2, and 3 after the E. coli challenge. Calves fed the CT diet showed decreased blood β-hydroxybutyrate concentrations compared with those on the CON and MLF diets before the E. coli challenge. Dietary supplementation with CT resulted in lower blood superoxide dismutase activity than the CON after E. coli challenge. The calves fed CT and MLF showed much lower blood glutathione peroxidase activity than the CON group after being challenged with E. coli. The tunica mucosa of the duodenum was lower in CT and MLF than in CON. The lactase activity of the jejunal digesta was greater in MLF than in CON and CT. In summary, MLF and CT supplementation might effectively improve antioxidant function and reduce the incidence of oxidative stress after challenge with E. coli in 28-d-old preweaning calves, and this effect may be partially explained by the relative decreases in blood superoxide dismutase and glutathione peroxidase as well as fecal score.

The aim of this study was to investigate the effects of dietary supplementation with two alternatives to antibiotics (Candida tropicalis and mulberry leaf flavonoids) on intestinal microbiota of preweaned calves challenged with Escherichia coli K99. Sixty Holstein calves were randomly assigned to 5 treatments: fed a basal diet (N-CON); fed a basal diet and challenged with E.coli K99 (P-CON); fed a basal diet supplemented with C.tropicalis (CT), mulberry leaf flavonoids (MLF), and the combination of the two additives (CM), respectively, and challenged with E.coli K99. The MLF and CM groups had significantly higher average daily grain and feed efficiency, and significantly lower fecal scores compared with the P-CON group after E. coli K99 challenge. The supplementation groups increased the relative abundance, at the phylum level, of Bacteroidetes and Proteobacteria, whereas at the genus level, they increased the relative abundance of Prevotella, Lactobacillus, and Enterococcus. Quantitative PCR revealed that the CT, MLF, and CM groups had significantly lower copy numbers of E.coli K99 compared with the P-CON group. The CT, MLF, and CM treatments reduce days of diarrhea, improve intestinal health, and beneficially manipulate the intestinal microbiota in preweaned calves.

“…They proposed that yeast removed the oxygen in the rumen, promoting anaerobic microorganisms' development, and therefore enhance fiber digestion. The positive effects of yeast in the ruminal environment could also be due to the interaction of yeast with the rumen microorganisms, stimulating certain microbial population with its consequent effect (Sirisan et al, 2013;Marrero et al, 2015). Mendes et al (2012) suggested that yeasts are able to degrade simple carbohydrates, which could favor the growth of yeast populations, and also contribute to the regulation of ruminal pH.…”

Molecular techniques are important tools for microbiological studies in different habitats, and the internal transcribed spacer (ITS) has been proved to be useful for analyzing fungal diversity. The aim of this study was to use the ITS region to generate ruminal yeast profile and to identify ruminal yeast. DNA from ruminal digesta was extracted to amplify the ribosomal ITS region. The profile from the PCR products was visualized and the excised bands from the profile were identified as the genera Millerozyma, Pichia, Rhizomucor and Hyphopichia. Overall, the ITS resulted to be a simple, fast and sensitive approach that allowed profiling and identification of ruminal yeast that have not been previously described (Millerozyma and Hyphopichia) in the rumen microbial community.
