Nutrition: Concentrate Feeds
Nutrition: Yeast metabolites
Live yeast contains active microorganisms that can directly influence rumen microbial populations. It promotes the growth of beneficial bacteria and fungi, aiding in fiber digestion and improving overall rumen function.
Yeast metabolites are derived from the fermentation process and may not contain live microorganisms. Instead, they consist of the byproducts of yeast metabolism, such as organic acids and metabolites. They highly influence microbial activity by providing substrates for microbial growth.
Stability and Shelf Life:
Live yeast products have a limited shelf life and may require specific storage conditions to maintain viability. They need to be handled carefully to ensure the survival of live microorganisms.
Yeast metabolites, being the byproducts of fermentation, are often more stable and have a longer shelf life. They may be easier to handle and store compared to live yeast.
Ease of Handling:
Handling live yeast requires more attention to environmental conditions, and special precautions are needed to protect the viability of the live microorganisms.
Yeast metabolites are generally easier to handle and incorporate into feed formulations. They offer a convenient way to provide some of the benefits associated with yeast without the challenges of handling live microorganisms.
Consistency in Performance:
The performance of live yeast may vary depending on factors like feed composition, storage conditions, and handling practices. Consistency in performance may be influenced by the viability of live microorganisms.
Yeast metabolites can offer more consistent performance since they are standardized products with defined compositions. This can lead to predictable outcomes in terms of animal response.
