Give cows extra bunk space

Doubling the amount of bunk space per cow reduces competition at the feedbunk, according to research reported in the May Journal of Dairy Science.

When bunk space increased from 1.6 feet per cow to 3.2 feet per cow, aggressive behavior at the bunk decreased by 57 percent in the University of British Columbia study. Feeding activity also increased 24 percent during the first 90 minutes after feed delivery — particularly among subordinate cows.

Therefore, giving cows more than the current industry standard of 1.5 to 2 feet of bunk space may help subordinate cows get enough to eat — especially during peak feeding times.
