Although yeast supplements have been hard to evaluate because of the slow nature of the effects, it has proven to be one the most reliable and cost-effective performance-enhancing feed ingredients. Live yeast can improve feed conversion efficiency by between 5 and 15%. This results in 1 to 2 liters of milk per cow.
It is often accompanied by other benefits such as improved milk quality, fertility, body condition, and overall herd health. You can also look for the most cost-effective yeast supplement for dairy cows by searching the query “all about feedworks”.

What is the Work of Yeast?
It has been extensively researched that live yeast's mode of action involves taking oxygen from the rumen and removing lactate. Rumen microbes are extremely sensitive to oxygen. Adding live yeast to the rumen can quickly remove oxygen and increase microbial activity. Yeast alters the microbial population of the rumen, stimulating both the growth and activity of lactic acid utilizing and fiber digesting bacteria.
Feeding yeast to dairy cows
To get the best benefits of yeast during the transition, early lactation and when the cows are most vulnerable to them, it is recommended to add yeast to the cows' diet at least three weeks before calving. Continue to feed the cows throughout lactation.
Results from Yeast Dairy Farm
Numerous trials have demonstrated the positive effects of feeding yeast. A team of veterinarians from Valcourt Farms, Dorset, used Yea-Sacc in 2004 to show the long-term benefits of yeast supplements.
