Yeast solutions show great promise in combatting heat stress damage

Published: June 6, 2018
The use of three different yeast solutions to reduce the damaging effects of heat stress in dairy cows has shown highly promising results according to Phileo Lesaffre Animal Care, France. The company’s solutions, fed as supplements to heat stressed dairy cows, were yeast probiotic, yeast paraprobiotic* and selenium yeast, with all three successfully helping to promote improvements i...

What is the difference between probiotic and prebiotic yeast products?

I think that high ambient temperature and feed in heat stress periods have negative impacts of efficiency of live yeast in the rumen. That's because live yeast is highly sensitive in high temperature and humidity conditions.

Hazem Hassanien , Probiotics interact with the microflora directly in many different ways. Certain probiotic yeast strains can suppress the growth of pathogenic bacteria, while supporting the beneficial bacteria. They may also have anti-inflammatory effect in the gut which is strain specific. On the other side prebiotics are certain molecules that are indigestible for the animal and used as a nutrient by the gut flora. They can help the growth of the gut flora, but their effect is more limited and less specific.
Live yeast is indeed sensitive to humidity and temperature but at Phileo we have developed technology to create stable form of live yeast that can resist up to 92 degrees Celsius and is adapted to the field application in ruminant farm conditions. You may notice that Actisaf is the only probiotic yeast that doesn't need vacuum bag.

Valentin Nenov Thank you for valuable comment. Are there company in egypt has agency for phileo company? I think that Actisaf could be used in pellets factories and no problem? Heat stable probiotic yeast is more important in pellets manufacturer. Regards Hazem Hassanien

I am yet to come into contact with yeast though I reside in the tropics near equator still heat stress can be realised during drier seasons of the year

Yes, specific yeasts are efficient against heat stress in dairy cows and ruminants. The statement of '...only probiotic yeast that doesn't need vacuum bag' is not correct; other yeasts sources can be found without vacuum bag ; it is also to be mentioned that some very stable yeasts can, in addition, be packaged under very protective atmosphere in order to extend the shelf-life beyond 12 months, as example 24, 36 months.

How did heat-stressed cows get the benefits of the products at the same time?

Imad Abdulmoniem Ahmad Let me know more. What is your dairy farm location? How about your cows nutrition? Are you using rumen protected amino acids? Regards Hazem

Can any one on this forum tell me who cultivates the yeast strains and where are they located? I would dearly like to do some trials under local conditions.

Levucell yeast by Lallemand animal nutrition, France which is also available in Punjab,India is a great product in this regard. I am dairy farming with 200 HF and Jersey cows in Punjab ,where temperature is soaring 44 degree centigrade in these days. Levucell always showed positive milk production results. It helps in maintaining the good dry matter intake of dairy cows even in harsh summer of Punjab. It is a great product and any dairy farmer can see differences in milk production. I can say this from my two year experience with Levocell yeast.

Can somebody explain how can this product be used on the farm level?
If it is included in the feed on the feed plant, what is the shelf life and stability of the feed?
How about dairy sheep? Can we feed it to the sheep?

dr. jamil .m. Actisaf can be fed to all ruminates and is suitable for dairy sheep as well. Its stability in mineral premix is 6 months and another 3 months in the feed during which period we can guarantee survivability of the live yeast.

Valentin Nenov how do I order and purchase this product for local trials?

I just want to ask, what stress markers do you use to see the oxidative/heat stress in ruminants? Kindly share the trial results, what parameters do you use that yeast is working well in reducing heat stress in ruminants?
