BMR corn silage boosts milk production

In a study at Michigan State University, cows fed brown midrib-3 mutation corn silage produced about 642.4 pounds more solids-corrected milk over one lactation than control cows fed a non-BMR corn silage. While the researchers did not observe an increase in milk fat content, the crude protein content was 3.02 percent for cows fed the BMR silage, compared to 2.87 percent for control cows.

Furthermore, the researchers noted that between 50 and 150 days in milk, the milk production increase during this time was greater for cows fed BMR-corn silage as compared to their herdmates fed a non-BMR diet. That means cows headed toward peak lactation showed the greatest milk production response when fed BMR corn silage.
