The effect of Saccharomyces cerevisiae on digestion and mortality in the volcano rabbit (Romerolagus diazi)

Saccharomyces cerevisiaeas a probiotic feed additive to non and pseudo‐ruminant feeding: a review

“…). However, (Campos‐Morales et al ) reported that inclusion of S. cerevisiae with 2 × 10 8 CFU per day per animal negatively affects digestibility of dry matter, organic matter and neutral detergent fibre, as well as increased mortality rate of rabbits.…”

The Review on the Function of Intestinal Flora and the Regulatory Effects of Probiotics on the Intestinal Health of Rabbits

“…Yakabe et al [29]suggested Lactobacillus brevis KB290 improves gut health and stimulates immune function., Which would be safe for pregnant females and their offspring.Simonova et al [30]conclude that administration of Enterococcus faecium CCM7420 (5.0 × 10 8 CFU/animal/day in their drinking water) strain to rabbits may improve weight gain due to better utilization of feed and larger absorption surface in the gut and also may positively influence the health status via enhancing the gut health in rabbits.Live yeast Saccharomyces cerevisiae NCYC Sc 47 was added to the diet of weaning rabbits (35d old) to analyse the effects on the caecal ecosystem (biotope and bacterial community), digestion and health status. The structure of the caecal bacterial community was not modified after 11d of yeast presence in the caecum, while the bacterial diversity tended to be higher [31].Campos-Morales et al [25]conclude that yeast supplementation in the volcano rabbit negatively affects digestion and mortality in captivity.Benato et al [9]investigate the effects of probiotics on faecalmicroflora shown that oral administration of probiotic E. faecium NCIMB 30183 to pet rabbits was associated with an increased level of faecal E. faecium after 2 weeks of dietary supplementation, but did not influence the levels of C. spiroforme, Bacteroides species and F. succinogenes.Oso et al [5]reported that the diet of adult rabbits containing probiotics (Prediococcus acidilactis, Bacillus cereus) enhance the caecal lactobacillus but lower the coliform counts. Meanwhile, the Clostridium count was not affected.…”

“…Probiotics are live microbial cultures of non-pathogenic bacteria or yeast species that help to equilibrate the intestinal microflora. Previous studies with rabbits indicated probiotics supplementation improves growth rate, enhances efficiency of feed conversion in rabbits, and also influences the intestinal microflora through the action of beneficial microbes [8,25]. The stable or improved intestinal environment and gut health directly influence the health status and growth performance of animals due to better nutrient absorption in the gut.…”
