“…In the present study, the rumen ammonia concentration was not affected by the yeast addition, as reported by others (Lila et al, 2004;Mwenya et al, 2005), although slight decreases in the ammonia concentration by LYC and YC for the L-NDF diet were observed. Decreased ammonia concentrations in the rumen caused by Saccharomyces cerevisiae were reported by Abd-El-Ghani (2004) and may indicate lower protein decomposition as well as faster flow of undegraded protein to the duodenum.…”

“…Piva et al (1993) observed a reduction of the acetate:propionate ratio when YC was fed to lactating cows, while total VFA was not affected. Mwenya et al (2005) reported increasing VFA concentrations, especially those of acetate and isoacids, in the rumen fluid and this may have indicated increased activity of cellulolytic bacteria. This effect was not observed in the present study.…”

The aim of the study was to determine the effect of live yeast culture (LYC) and dehydrated yeast culture (YC) containing Saccharomyces cerevisiae on fermentation parameters and degradability in the rumen of sheep fed a high-(H-NDF; 56% DM) or low-(L-NDF; 35% DM) NDF diet. Three Polish Merino sheep fitted with ruminal cannulas were used. The effective degradability of maize grain and wheat straw was measured by an in situ procedure. Ruminal pH, ammonia, total volatile fatty acid concentrations, and molar percentages of acetate, propionate and butyrate were not modified by the addition of LYC or YC, irrespective of the applied diet. Compared with control (CON) and LYC supplementation of the L-NDF diet significantly (P<0.05) increased the caproate concentration, but in the H-NDF diet, it increased the lactate concentration (P<0.05). In situ rumen NDF degradability of maize grain and wheat straw was not affected by the treatments. When the sheep were fed the H-NDF diet, however, degradability of dry matter maize grain was significantly higher (P<0.05) than in the CON group. The results of this study did not confirm the hypothesis that NDF in the diet is the main reason for the considerable inconsistencies in the results of experiments with Saccharomyces cerevisiae products.

“…Yeasts, in particular different strains or commercial products of Saccharomyces cerevisiae, have been tested on dairy cows with a number of positive effects such as increased dry matter intake (DMI) and milk production (Wohlt et al,1998;Dann et al, 2000); improved diet digestibility (Erasmus et al, 1992;Marden et al, 2008); stabilized rumen pH (Bach et al, 2007); and stimulated rumen bacteria growth (Newbold et al, 1995). However, there are also many studies with no or negative responses to yeast supplementation (Mwenya et al, 2005;Longuski et al, 2009;Chung et al, 2011), probably related to the strong influence of the basal diet, the variation in yeast strains and the different commercial formulations.…”

Host and dietary interactions with the rumen microbiome can affect the efficacy of supplements, and their effect on the composition of the bacterial population is still unknown. A 16S rRNA metagenomic approach and Next-Generation Sequencing (NGS) technology were used to investigate the bacterial microbiome composition in the liquid fraction of the rumen content collected via stomach tubing. To investigate biodiversity, samples were taken from three groups of four lactating dairy cows given a supplement of either 50 g of potato protein (Ctrl group), or 50 g of lyophilized Saccharomyces cerevisiae (LY group) or 50 g of dried S. cerevisiae (DY group) in a potato protein support. Rumen samples were collected after 15 days of dietary treatments and milk production was similar between the three groups. Taxonomic distribution analysis revealed a prevalence of the Firmicutes phylum in all cows (79.76%) and a significantly (P < 0.05) higher presence of the genus Bacillus in the DY group. Volatile fattyacid concentration was not significantly different between groups, possibly because of relatively high inter-animal variability or limited effect of the treatments or both, and the correlation analysis with bacterial taxa showed significant associations, in particular between many Firmicutes genera and butyrate. Limited differences were observed between dietary treatments, but the lack of microbiome data before yeast administration does not allow to draw firm conclusions on the effect of dietary treatments.Keywords: rumen bacteria community, Saccharomyces cerevisiae, Next-Generation Sequencing, 16S rRNA, dairy cows Implications Next-Generation Sequencing technology offers the opportunity to gather information regarding the rumen microbiome by comparing repository databases of rumen bacteria 16S rRNA gene sequences generated through different experiments. The high extent of sequencing attained through this research provides valuable information on the microbial biodiversity of the liquid phase of the rumen and represents a contribution to research in rumen microbiology and dairy feed supplements. However, the effectiveness of yeast supplements to modify the rumen bacterial microbiome requires further investigation.

“…Although some prebiotics such as scFOS, OF, inulin, mannanoligosaccharides (MOS) and galactooligosaccharides have been supplemented to cows (Mwenya et al, 2005), calves (Masanetz et al, 2011) and lambs (Thayne, 2007) and some information is available on the effects of feeding prebiotics in selected species mentioned above (Swanson et al, 2002a), there is no information on the effects of supplemental inulin in kids.…”

Fifty newborn Saanen kids were used to study the effects of inulin supplementation on faecal score, faecal pH, selected faecal bacterial population, BW, body temperature, haematological traits, selected health parameters and the incidence of diarrhoea. Kids were sorted by parity of their dams and multiple birth (twin or triplet) and assigned to one of the two groups (control: CG, and experimental: EG) at birth. Each group consisted of 25 kids. The groups were similar with regard to sex and birth weight. All kids were fed colostrum for the first 3 days after birth, and then the kids in EG were adapted to inulin supplementation by an increased dosage from day 4 to 7. Each kid in EG was supplemented with 0.2 g, 0.3 g, 0.4 g, 0.5 g and 0.6 g inulin on day 4, 5, 6, 7 and from day 8 to 28, respectively, whereas the kids in CG did not receive inulin. Faecal score and faecal bacterial population were not affected by inulin supplementation (P . 0.05). There were differences in faecal pH on day 14 (P 5 0.01) and 28 (P,0.05), whereas no difference in faecal pH on day 21 (P . 0.05) was detected between groups. No differences (P . 0.05) in BW and haematological traits were found between groups. Body temperature did not differ on day 14 and 21 (P . 0.05), whereas there was a difference in body temperature on day 28 (P 5 0.01) between groups. The numbers of kids with pneumonia and kids treated for pneumonia and diarrhoea were similar for CG and EG. Kid losses during the study were the same for CG and EG. The incidence of diarrhoea was not affected by inulin supplementation (P . 0.05). Inulin supplemented to kids did not adversely affect faecal score. The effect of inulin on faecal pH was not consistent. The results of our study suggested that daily dose (0.6 g) of inulin might not be enough to observe effects of it. Our data will be useful to determine the dose and timing of inulin supplementation in future studies investigating the effects of inulin on the parameters associated with performance and health status in kids and other young ruminants.
