Eight studies were conducted to evaluate the effect of feeding whey silage on production and digestibility characteristics of growing and finishing cattle and beef cows. Whey silage was produced by combining cereal grain straw, wheat middlings and liquid whey. Growing cattle and beef cow ration costs were decreased significantly without affecting performance or feed digestibility when whey silage was the main or sole roughage source. There was no benefit for feeding whey silage to finishing cattle. These studies confirm that there are value-added opportunities for the use of these residue feeds for beef cattle.
1. Determine production and carcass characteristics of growing and finishing cattle and beef cows under maintenance conditions fed ensiled products that were derived from combining “sweet” or “acid” liquid whey, low-quality roughage sources and a concentrate source.
2. Determine nutrient content of these derived silage products.
3. Evaluate economics of production for whey silage compared to traditional corn silage-based diets and for cattle fed these silages.
4. Disseminate research results derived from these studies to beef producers, extension and industry personnel in the Intermountain West.
