A study published in the November 2012 issue of the Journal of Dairy Science (pages 6665-6676) found that the benefits of feeding dairy cows a corn silage with high fiber digestibility may continue long after the silage is replaced with a silage that has a lower fiber digestibility.
In the study, pre-fresh cows (starting 3 weeks before calving) were fed diets with about 47 percent corn silage, 18 percent straw, 7 percent mixed silage, and 28 percent concentrate (dry matter basis).
In the November 2012 issue of Buckeye Dairy News, Bill Weiss, professor and extension dairy specialist with The Ohio State University, takes a look at the research findings.
"The bottom line to this research is that the milk yield benefits of feeding highly digestible corn silage to transition dairy cows may continue for at least 2 or 3 months after the silage is removed from the diet," Weiss says.
