Too basic? Maybe. However, considering the current challenges with forage because of the drought the key takeaways are about particle size and length plus cow observation.
Cud chewing is the regurgitation of feed that has already been consumed and swallowed. The regurgitated feed is re-chewed to an acceptable particle size and then re-swallowed.
But wait . . . there’s more:
- Dairy cows spend almost eight hours each day chewing their cuds
- Forage particle length is important
- Cud chewing secretes saliva
- The saliva contains a natural antacid that helps buffer the rumen.
- Proper buffering of the rumen allows cows to digest forages better, eat more feed
- More feed consumption helps the cow produce more milk.
