Last winter we did a side by side test: netwrapped hay and B-Wrapped hay. Both bales came from the same field – they were actually baled the same day. We unrolled the netwrap bale first, just the regular netwrap. Cows went to it. We came back up and unrolled the B-Wrapped bale second, and every cow that was in the netwrap bale went to the B-Wrap™ bale, in a matter of about 30 seconds.
