Soybean Hulls: Composition and Feeding Value for Beef and Dairy Cattle

---

Kansas’ stature as a dominant agricultural state is attributed heavily to its ranking as
a producer of crops and cattle. Although Kansas often is referred to as the Wheat State,
few realize the significant effects of other crops such as soybeans on the state’s
economy. For example, the approximately $500 million dollars generated annually by
the soybean industry in Kansas ranks 10th in the nation. According to USDA estimates,
there are more than 14,000 identified soybean farmers in Kansas, and each operator
averages 186 acres.

Over the past 5 years alone, Kansas soybean production has increased in terms of
both acres planted and bushels harvested. In 1998, soybean acreage increased to 2.55
million acres from 2.40 million acres planted in 1997. As a result, about 4 million
additional bushels of soybeans were harvested (29 bushels/acre average yield).
K-State agricultural economists predict continued expansion of soybean acreage; more
than 2.60 million acres were planted to soybeans in 1999. This acreage increase
potentially represents an additional 1.5 million bushels of soybeans harvested.

The Kansas beef industry is a dominant one; a combination of more than 4 million
stockers and feeders imported into the state and the calves derived from the 1.5-
million-head resident population of beef cows contribute to the demand created by the
5-million head capacity of the Kansas feedlot industry. Additionally, the Kansas dairy
industry includes about 90,000 cows that produce approximately 1.6 billion pounds of
milk each year. Feed costs, which account for approximately 50% of total costs, are
major considerations for efficient production of beef and dairy cattle. Because of their
location in the Midwest, where large volumes of feed grains and oilseeds are grown
and processed, Kansas beef and dairy producers have tremendous opportunities to
significantly reduce feed costs through the use of by-products such as soybean hulls.

If readily accessible and priced competitively with other feedstuffs, soybean hulls
can reduce feed input costs. The estimated yield of soybean hulls from a 60-pound
bushel of soybeans is about 3 pounds, or approximately 5% of the original raw soybean
weight. Based on this yield, the harvest projections for the 1999 Kansas soybean crop
could result in the production of almost 115,000 tons of soybean hulls. This publication
contains information related to the nutrient composition and feeding management of
soybean hulls, which will help Kansas livestock producers capitalize on the
opportunity to use soybean hulls.
