improvement of feed utilization - improvement of animal health

jbs yeast 5/10 contains: live yeast, inactive yeast, calcium carbonate, wheat bran (thickener)

Packaging: 20-kg-bag

Usage:

jbs yeast 5/10 should be fed regularly in sufficient quantities. We recommend a dosage of 1g per kg  dry matter intake     (e.g. with a TMR / forage ration mixer). The applied carriers enable an accurate  distribution because of their large volume combined with low weight. Main application of  jbs yeast 5/10 should be 1-2 weeks before calving, throughout lactation until the dry period has been reached.

As dry matter intake of cows shortly before calving is low,  less jbs yeast 5/10 is needed. Thus the usual costs of feeding are almost being halved during this period.

jbs yeast 5/10 is also effective with fed cattle and cow breeding (see information chart), so jbs yeast 5/10 is also worthwhile in feed rests. Of course you should as always make sure to feed only rests of immaculate quality.

Feeding fresh forage frequently improves feed intake and therefore also the energy supply  of dairy cows and cattle.

Also our customers confirmed these general results from a jbs-field test run on 111 farms. Daily milk yield increased on all farms by an average of 0,68 kg. On farms with feed groups the daily milk yield even increased by 1,59 kg. Positive effects on animal health were noted especially in the area of acidosis and ketose disorder metabolism. 100 % of the farms with feed groups and 90 % resp. 80% of all farms showed very good results.

Effects of live yeast in the rumen:

1. jbs yeast consumes oxygen in the rumen. Oxygen is toxic for most ruminal microorganisms. By depriving oxygen jbs yeast supports the growth of micro flora. Especially microorganisms which metabolize cellulose increase their activity. This is revealed after a short time in the animal´s faeces; less rests of fiber and grains are visible. In addition more free hydrogen is available, because of oxygen bonding to jbs yeast, which is badly needed for the production of propionic acid.

2. jbs yeast stimulates the production of volatile fatty acids. The performance of  micro flora improves: better digestion of cellulose and the production of volatile fatty acids rises.  Thus more energy is available for muscles and udder.

3. jbs yeast increases microbial synthesis and improves the flow of microbial protein (BCP), by optimising the conditions necessary for the growth of ruminal bacteria. Thus more high-quality bacterial protein is available to the cow. Ruminal microbes produce vitamins and other valuable products which are essential for the cow´s metabolism e.g. vitamin B and C, biotin, essential amino acids and enzymes.

4. jbs yeast keeps the pH-value of the rumen in optimal range.
The risk of acidosis diminishes when feeding high-energy forage rations because of an increased conversion of lactic acid into propionic acid.   Especially bacteria, which are able to converse lactate, are highly stimulated. The ruminal pH-value is kept at the required level and microflora is thus being protected.

Stabilizing pH-values

Stabilization of ruminal pH is of particular importance in high-energy rations (see graphic). When milk production of a cow is low, it is sufficient to feed high-fiber forage to supply the cow with enough energy (yellow curve). When milk performance is rising though, rations higher in energy and starch are needed e.g. concentrated feed or mash. Decomposition of starch / carbohydrates causes an increased production of lactic acids in the rumen so that pH goes down (black curve). 

At pH < 5,8 there is a high risk of necrosis of ruminal bacteria in great quantities so that the mucous membrane of the rumen is irreversably damaged.

jbs yeast avoids this process of taking place and the pH-value stays in its safe range of more than 6 (green curve). Ruminal bacteria and mucous membranes are thus being protected.
