Cows that ate brown mid-ribcorn silage during the transition period not only ate more dry matter, but also gave more milk well into lactation, according to research from Cornell University.

Cows fed brown mid-rib silage from about 3.5 weeks pre-freshening to 3.5 weeks post-freshening averaged 6.6 pounds more fat-corrected milk per day during the first 15 weeks of lactation than those fed traditional corn silage. In other words, the production advantage persisted well into lactation after the experimental diet ceased and all of the cows were receiving a common diet.

The persistence in milk production may be due to improved metabolic status in the transition cows.
