文摘
- •
A yeast culture (XPC) or yeast/microbial culture (YST) were added to a Control (C).
- •
Milk yield was higher with YST, but not XPC, and NE output was higher vs. C for both.
- •
There were no impacts of YST or XPC on measures of rumen fermentation.
- •
Lower digestion of organic matter and protein for YST vs. C occurred.
- •
A post-ruminal YST effect improved gut health causing higher absorption efficiency.
