“…Significant (P<0.05) increase in IVDMD and IVOMD with yeast supplementation was also observed by Harikrishna et al (2012), Elmasry et al (2016) and Elanthamil et al (2018). Elanthamil et al (2018) noticed highest IVDMD in 0.5  10 8 CFU level (56.42%) against non-supplemented group (48.09%). Regarding the effect of added chromium to yeast (1.5Cr+Y), higher cumulative degradability (at 12 h, 24 h and 48 hr) and effective DM degradability was observed in comparison to control and the values were comparable with yeast supplemented group (Y) (Table 3, 4).…”

“…However inconsistent results were observed regarding TVFA concentration with yeast supplementation compared to previous studies. Enjalbert et al (1999) and Bayat et al (2015) observed no effect of yeast on TVFA concentration and their molar proportions whereas higher concentration of TVFA was reported by Mao et al (2013), Elghandour et al (2014a) and Elanthamil et al (2018) on forage based diet. As per Wallace and Newbold (1992), the variable response in VFA production and patterns is a consequence of the effects of yeast culture on microbial numbers in the rumen rather than a direct effect on ruminal fermentation.…”

Background: Yeast (Saccharomyces cerevisiae), widely used probiotics, was found to increase the utilization of fiber and improve the production in ruminants. The concept of chromium (Cr) supplementation has also received a great deal of attention since past decade, as Cr could have supra-physiological benefits for domestic livestock. The present in vitro experiment was conducted to investigate the effect of dietary chromium and yeast supplementation on in-vitro dry matter degradability and rumen fermentation by rumen simulation technique. Methods: The yeast (Saccharomyces cerevisiae) (Y) (5 x 109 CFU /kg) and chromium (Cr) (1.5 mg/kg) supplementation to sorghum stover based complete diets (Basal diet: 10.58% CP) either alone or in combination on in vitro nutrient degradability and rumen fermentation was assessed by rumen simulation technique. Result: Chromium supplementation alone did not affect the cumulative degradability and effective dry matter degradability in vitro compared to BD. Yeast supplementation enhanced (P less than 0.01) in vitro DM degradability on 12, 24 and 48 h, effective DM degradability and lowered (P less than 0.01) ammonia nitrogen level in comparison to control. When compared to control, combination of yeast and Cr positively affected rumen fermentation pattern and in vitro nutrient degradability but no further improvement was observed compared to only yeast supplementation in diet.

The purpose of this study was to determine how ruminal Crabtree-negative yeast affects the nutritional characteristics of winged bean (Psophocarpus tetragonolobus) tubers (WBT), in vitro gas and digestibility, and rumen fermentation. The experiment was carried out in a randomized complete design with a 5 × 2 (+1) factorial arrangement. Factor A determined the WBT products (a1 = dry WBT, a2 = fermented WBT without yeast in media solution, a3 = fermented WBT with Pichia kudriavzevii KKU20, a4 = fermented WBT with Candida tropicalis KKU20, and a5 = fermented WBT with Saccharomyces cerevisiae), whereas factor B determined the level of fermented WBT replacing cassava chips (b1 = WBT at 50% and b2 = 100% levels). The results of the experiment showed that the fermentation approach could increase the crude protein (CP) content of WBT by around 7% (p < 0.01). The WBT fermented with yeast lowered the number of aerobic bacteria during the fermentation process (p < 0.01). P. kudriazevii KKU20 yeast strain had a 17.3% higher final asymptotic gas volume (Vf) than the C. tropicalis KKU20. Crabtree-negative yeast had a higher in vitro dry matter digestibility (IVDMD) than Crabtree-positive yeast after 12 h of incubation (p < 0.01). Fermented WBT with yeast had a higher IVDMD after 24 h of incubation than fermented WBT without yeast in the media solution (p < 0.05). The fermented WBT with C. tropicalis KKU20 enhanced propionic acid (C3) concentrations when cassava chips were replaced for half of all of the diet (C3 ranged from 26.0 to 26.4 mol/100 mol; p < 0.01). Furthermore, Crabtree-negative yeast isolated from the rumen stimulates rumen bacteria more effectively than Crabtree-positive yeast (p < 0.01). According to our findings, nutritional enrichment with yeast might increase the in vitro gas production and digestibility of WBT. The study also demonstrated that Crabtree-negative yeast has a promising lead in terms of improving rumen fermentation quality. However, further research is required before deciding on an effective approach for optimizing the potential of WBT as a feed source.
