“…Results obtained in this experiment confirmed the finding of other authors that Yea-Sacc stimulates milk yield in cows (Dildey, 1988;Harris and Lobo, 1988;Williams, 1989;Harris and Webb, 1990;Williams and Newbold, 1990;Wallace and Newbold, 1992;Skorko-Sajko et al, 1993). One of the interesting results is that supplementing diets for cows with Saccharomyces carlsbergensis SK-1 affected not only milk production but also tended to increase protein and decrease fat content in milk.…”

“…The higher milk yield after supplementing diets with yeast preparations was probably caused by higher DM intake compared with the control group (Williams and Newbold, 1990;Wohlt et al, 1991). The advantageous effect of yeast preparation on milk production, which was marked during all periods of the experiment, could also be a result of a better established fermentation pattern in the rumen compared with that in control animals (Harrison et al, 1988;Adams et al, 1995).…”

“…Recent studies have concentrated on new yeast strains and fungi that increase the effects of ruminant nutrition (Fondevila et al, 1990;Williams and Newbold, 1990;Moore and Headon, 1992;Wallace and Newbold, 1992;Dawson, 1993). Strzetelski et al (1995a,b) obtained yeast preparations containing different strains of Saccharomyces carlsbergensis yeast and demonstrated their suitability for feeding calves and fattening bulls.…”

A study was conducted on 28 cows between the third week preceding and fourteenth week after calving. The cows were divided into 4 groups of 7. The animals in the control group (C) were fed a basic ration consisting of maize and beet top silage, meadow hay, soyabean oilmeal, concentrate for extra milk production and mineral mixtures according to the INRA system. This ration was supplemented for the experimental groups with Yea-Sacc preparation (Y) or with preparations containing baker's yeast Saccharomyces cerevisiae Gl produced according to a cell-engineering method (X) or Saccharomyces carlsbergensis brewery strain SK-1 (S).Average milk production during the experimental period in the respective groups was, in kg: 26.7 -C; 28.2 -X and S; 27.7 -Y; the milk-fat content: 4.05; 4.01; 3.99 and 4.29% and protein content, 3.01; 2.98; 3.09 and 3.15%. The persistence of milk yield after the peak of lactation was greater in cows receiving a yeast supplement than in the cows of the control group.

“…These differences cannot be clearly attributed to the species and physiological state of animals or to diet composition. Our results suggest that live S. cerevisiae did not affect digestion in the rumen or that its effect was masked by greater hindgut fermentation in control rams as compared with animals fed live yeast (19). On the other hand, Moharrery and Asadi (16) showed that cellulase activity in the rumen was higher in lambs fed live yeast compared with animals on a control diet.…”

“…No differences were found between the total digestive tract digestibility of feed in control and experimental animals. This suggests that live cultures of Saccharomyces cerevisiae had no effect on the digestion processes in the rumen or that their influence was masked by greater hindgut fermentation in control -as compared with the experimental animals (Williams, 1989;Williams and Newbold, 1990). Due to this, total tract digestibility studies do not characterize the effect of the added yeast on the digestive processes in the rumen.…”

The influence of live Saccharomyces cerevisiae yeast on the fibrolytic activity in rumen digesta and on total digestive tract nutrient digestibility in cows was examined in a 2 × 2 Latin square design. The animals were fed hay-concentrate diet alone or supplemented with yeast at the rate of 5 g/d. Addition of Sacchromyses cerevisiae decreased the activity of CMC-ase and xylanase when measured before feeding but had no effect on the diurnal variations in activity of these enzymes. The digestibility of dry matter, organic matter, crude fibre, ADF and NDF was not affected.
