The introduction of the Single Farm Payment support system sees a change from headage to area payments. The removal of the Beef Special Premium for steers is likely to see a move towards either 12-15 month intensive finishing systems or low input extensive grass based 24-30 month finishing systems. Late maturing breed type cattle reared on the latter system may however require a 2-3 month intensive finishing period to achieve adequate fat cover. With falling cereal prices there is increased interest in their use in beef cattle rations. Antibiotic based feed additives e.g., monensin sodium, have been successfully used for over 40 years to manipulate microbial activity and improve beef cattle performance. The use of monensin sodium will be banned from January 2006 and there is therefore a requirement to find alternative ‘natural’ products that can improve the efficiency of beef production with intensive cereal based rations. Yeast cultures are composed of yeast (Saccharomyces cerevisiae ) and the medium on which it was grown. These products are dried in a manner which preserves the fermenting activity of the yeast. It is suggested that production responses associated with the use of live yeast culture supplements in ruminants may be related to their stimulatory effects on specific groups of micro-organisms in the rumen. The objective of this study was to determine the effect of feeding a live yeast culture (Yea-Sacc1026) on the performance of cereal fed beef cattle.

Effect Of Feeding

There is increasing consumer resistance to feeding antibiotic performance enhancers to beef cattle which has created interest in the use of yeast cultures as an alternative. Yeast cultures such as Diamond V ‘XP’ (Rumenco) are produced by growing selected yeast strains (on a semi-solid medium under stressed conditions) which are then dried. Yeast cultures are now used in a considerable number of North American beef feed lots. The objective of this work was to evaluate the effect of feeding ‘XP’ Yeast to finishing beef cattle on a typical UK grass silage-based diet.

Any method to increase the utilisation of nutrients from feeds given to horses exercised on a regular basis is important. Commercially-available dried yeast cultures, used as supplements to equine diets have been shown to increase the digestibility of gross energy and enhance the retention of N in yearling horses (Glade and Biesik, 1986). There is however, limited information on whether the increase in digestibility of GE or enhancement in retention of N occurs in mature horses (Glade and Campbell-Taylor, 1990). The aim of the research reported here was to determine the effect of a dried live yeast culture on the digestibility of nutrients from a mixed diet given to riding school horses.Six 2 and 3 year old riding school horses (mean live-weight 433 (s.e. 11.1) kg) were allocated to three balanced 2 x 2 Latin squares with two treatments and two periods of 3 weeks. The first 14 days of each period was a preliminary and the last 7 days was for measurement. The horses were housed individually (bedded on saw dust) and given 13.5 kg DM hay and 3.0 kg DM concentrate mix as a base diet. The base diet was either supplemented with 10 g dried yeast culture (S) or not supplemented (N).

Experimental Conditions

In the last twenty years, some probiotics, such as Aspergillus oryzae or A. niger (Pioneer, 1989), yeast culture (Saccharomyces cerevisiae) (Wallace, 1994) and some microbial growth promoters (e.g. thiamine, niacin) (Shield, 1981), were used as feed additives in order to improve rumen conditions and cellulose digestion in the rumen and milk yield of dairy cows. The present study was planned to determine whether dietary supplemental baker's yeast and niacin would have individual and/or synergistic effects on milk yield and milk composition of dairy cows under our experimental conditions.

Performance horses are often fed very energetic diets including large amount of grains. Thus, a important quantity of soluble carbohydrate is bound to reach the hindgut, altering biochemical and microbial composition of the intestinal contents (Julliand et al., 1999) and leading to a wide variety of diseases like colic, laminitis and diarrhoea (Clarke et al., 1990). In high concentrate rations, live yeast cultures have been reported to stimulate specific groups of bacteria, and moderate large ruminal pH decreases (Williams et al., 1991). Therefore, this trial was designed to evaluate the effect of a live yeast culture preparation (Yea Sacc1026™) on the activity of the intestinal ecosystem (caecum and colon) of horses fed high fibre (HF) or high starch (HS) pelleted feeds. This current summary reports only the results of the nutrient digestibility in vivo and the ability in vitro of large intestine fluid contents to degrade straw.

Effect Of Feeding

There is considerable interest in the effect of dietary supplementation with probiotics or yeast cultures on diary cow performance. Yeast cultures such as Diamond V 'XP' are produced by growing selected yeast strains on a semi-solid medium under stressed conditions, which are then dried. Yeast cultures are now used by a majority of the high yielding herds in North America (McCullough 1995). The objective of this work was to evaluate the effect of feeding 'XP' Yeast to a moderate-high yielding (X, 6800kg) herd of dairy cows fed a typical UK diet based on grass silage.72 recently calved Holstein-Friesian dairy cows were allocated to one of two dietary treatments on which they remained throughout 150 days of winter feeding. Both groups received ad libitum grass silage which had a Dry Matter of 224 g/Kg, an estimated ME of 10.8 MJ/Kg DM and a Crude Protein (CP) of 156 g/Kg DM.

Live Yeast

Yeast culture (YC) based on Saccharomyces cerevisiae has been reported to stimulate bacterial activity within the rumen, leading to increases in ruminal fibre digestion and microbial protein flow from the rumen (Wallace and Newbold, 1992). Dawson (1987) suggested that S. cerevisiae might grow in the rumen. Newbold et al (1990) found no evidence for the growth of S. cerevisiae in the rumen of sheep when the numbers of live yeast in the rumen were measured at various times after a diet contain YC had been consumed. The current experiment was designed to investigate further the possibility that S. cerevisiae grows in the rumen and to establish the importance of viable yeast cells in the action of YC in the rumen.

Stimulation Of

It has been suggested that the mechanism by which yeast cultures (YC), based on Saccharomyces cerevisiae, improve ruminant production is by stimulating rumen fibre digestion and microbial protein flow from the rumen. Both of these effects have in turn been related to the increases in bacterial growth in the rumen observed when YC is added to the diet. However, although it is has been shown that the effectiveness of YC in improving productivity is influenced by the composition of the diet fed (Williams and Newbold, 1990), little is known about how the ability of YC to stimulate bacterial numbers in the rumen is affected by diet composition.The effect of diet on the stimulation of bacterial numbers in the rumen by YC was investigated in the rumen simulation technique (Rusitec). Grass silage was prepared from a sward of perennial rye-grass, without the use of a preservative. Fresh grass was collected from the sward prior to ensilage and stored at -20°C. Grass (5.96 g dry matter (DM) /day) and grass silage (6.54 g DM/ day) were compared alone or supplemented with 500 mg / day YC (Yea-sacc, Alltech), in triplicate, in an experiment lasting 21 days.Four rumen cannulated sheep, allowed ad lib access to grass silage, were used to investigate further the effects of YC on bacterial numbers in the rumen in vivo. The effects of YC (4 g/ day) were investigated in a 2 × 2 factorial design with 28 day periods.

Production Technique

Yeast culture (Saccharomyces cerevisiae) has been widely used as a dietary supplement in ruminants. Saccharomyces cerevisiae supplementation in ruminant diets can increase dry matter intake, production performance, cellulose degradation, and nutrient digestibility (Callaway and Martin, 1997). In vitro techniques are routinely used to evaluate the nutritional quality of feeds because of their convenience, adaptability and efficiency. The in vitro gas production technique is an accurate and fast method to evaluate the nutritive value of feeds and it can be a good alternative method instead of in vivo trials to evaluate commercial feed additives. The objective of this study was to evaluate the effects of different levels of inclusion of Saccharomyces cerevisiae on the nutritive value of lucerne hay using the in vitro gas production technique.
