Research reveals benefits of straw in dairy rations

According to recent research, incorporating straw into the diets of lactating dairy cows can provide a number of benefits:

1. Helps improve rumen function and fermentability of other feedstuffs in the diet that tend to exit the rumen quickly. 
2. Encourages cud chewing.
3. Aids in the proper development of a healthy rumen fiber mat.

Researchers have also found straw to be a valuable feed ingredient for dairy animals at other stages of their lives:

Pre-weaned calves: Higher ADG and starter intake may lead to improved rumen development.

Growing heifers: Dilutes energy density of the diet and helps prevent excessive body weight gain.

One group dry cow: Allows for high consumption without feeding excessive energy.
