“…Yeast cultures, mainly Saccharomyces cerevisiae, may also improve ruminal fermentation (Newbold et al, 1996) and therefore provide another enhancer for microbial growth. 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 (Strzetelski et al, 1996). However, the results on the use of S. cerevisiae in dairy cows (Dann et al, 2000) and dairy goats (Salama et al, 2002) are also contradictory.…”

The objectives of this study were to determine the effects of adding a mixture of malate and yeast culture (Saccharomyces cerevisiae) on cellulolytic, amylolytic, proteolytic and ureolytic activity in the rumen and on the growth performance of lambs. Eight native breed (Lory-Bakhtiary) lambs aged approximately 7 months (four males and four females) were divided into two groups by sex. They were kept in individual pens and fed a total mixed ration (TMR) based on lucerne hay-wheat straw and concentrate. The two groups of lambs were randomly assigned to each of the dietary treatments in a cross-over design: control (without supplementation) and supplemented (with malate and yeast included in the TMR at a level of 10 g · kg -1 ). The experiment was divided into 2 periods, in which the lambs received one diet in the fi rst three-week period, after which they were transferred to the other diet for another three weeks. Urease, cellulase, protease and amylase activities were determined in rumen fl uid and rumen microbial biomass. Rumen samples were taken 3-4 h after feeding at the end of each period. The weights of lambs were recorded at the beginning and end of each period. RNA equivalents (RNA-e) in rumen fl uid and urine were measured for determination of microbial status in different samples. Supplementation with the malate-yeast mixture increased daily weight gain (from 196 in controls to 259 g/d) but did not affect (P>0.05) feed intake (0.970 vs 0.929 kg DM/d for the control vs the supplemented lambs, respectively). Higher cellulase activity was observed in lambs on the malate-yeast diet compared with the control lamb diet. A signifi cant but moderately positive correlation was found between cellulase and protease activities (r=0.5188; P=0.0395). No signifi cant differences were observed between the two treatments for dry matter, neutral detergent fi bre and crude protein apparent digestibilities (P>0.05). Neither was microbial biomass (based on RNA-e concentrations) affected by the malate-yeast treatments (P>0.05).

When evaluating the effects of yeast culture (Saccharomyces cerevisiae $ ) supplied with or without a vitamin premix and mineral bioplexes on some intermediates and end-products involved in the synthesis of milk constituents in 30 earlylactation Black and White Lowland cows, no significant differences were found in the glucose level, mineral contents and enzyme activities of the blood serum. The effect of yeast culture on the availability of minerals for milk synthesis depended upon the dynamics of degradation of mineral bioplexes in the rumen and the cows mineral status. The insignificant increase found in blood total protein content and the simultaneous small differences in blood urea nitrogen (BUN) and milk urea nitrogen (MUN) values in cows supplied with the yeast culture were probably associated with a high ammonia incorporation into microbial protein in the rumen, which increased protein supply for milk protein synthesis and decreased the nitrogen loss.

Influence of pre-and postpartum supplementatIon of fIbrolytIc enzymes and yeast culture, or both, on performance and metabolIc status of daIry cows* * M a g d a l e n a Ł o p u s z a ń s k a -R u s e k , K r z y s z t o f B i l i k Department of Animal Nutrition and Feed Science, National Research Institute of Animal Production, 32-083 Balice n. Kraków, Poland abstract the aim of the study was to determine the degree to which feeding total mixed rations (tmr) with fibrolytic enzymes and/or live yeast cultures to periparturient dairy cows will affect feed intake and conversion, milk yield and chemical composition, and metabolic and reproductive parameters of the cows. the experiment was conducted from 3 weeks before calving to 10 weeks of lactation on 36 polish red-and-white holstein-friesian (phf red) cows assigned to four analogous groups, 9 animals each. cows from the control group (c) were fed an unsupplemented diet, those from group e received a diet supplemented (15 g/day) with enzyme preparation (fibrozyme tm ) containing a blend of active xylanase and cellulase, cows from group d a diet with yeast preparation (yea -sacc 1026 ) supplemented (10 g/day) with Saccharomyces cerevisiae 1026 live yeast culture, and cows from group ed were fed a diet supplemented with a mixture (25 g/day) of both feed additives. the preparations were added to the concentrate included in the tmr diet. It was found that groups e and d showed a tendency towards higher dry matter and nutrient intake compared to group c. In groups e, d and ed there was also a tendency towards higher milk yield (by about 4-12% in the first 3 weeks of lactation) and slightly higher crude protein content (by an average of 0.16, 0.09 and 0.04 percentage units, respectively), without a clear effect on the other milk constituents. significantly (p<0.05) lower milk urea content was also noted in group e compared to group c. cows from groups e and d compared to group c, were characterized by better (p<0.05) efficiency of feed and nutrient conversion for kg milk production, especially during the first three weeks after calving. the experimental cows also showed a tendency towards improved blood metabolic profile, especially decreased levels of beta-hydroxybutyric acid (bhba) and reduced activity of aspartate aminotransferase (ast). the investigated preparations had no significant effect on the body weight, body condition and reproductive parameters of the cows.
