Take Home Messages Dairy or feed efficiency reflects the level of fat-corrected milk yield produced per unit of dry matter consumed with an optimal range of 1.4 to 1.8 pounds of milk per pound of dry matter. Days in milk, age, growth, changes in body condition score, body weight, forage quality, feed additives, and environmental factors will impact feed efficiency values. Dairy managers sho...
Did I interpreted this statement wrong or it is a typo error:
•As NDF (neutral detergent fiber) percent in the ration dry matter increased, DE declined from 1.8 to 1.4 based on Journal of Dairy Science data from 2002 to 2004. DE values remained constant at 35 percent NDF and above
The confusion may be DE stands for dairy efficiency (not digestible energy) which I used instead of feed efficiency. The take home message is as NDF levels increase in the ration up to 35%, feed efficiency declined reflecting less starch and fermentable fiber). Hope this helps! Mike Hutjens
