Commerical Feedlot Evaluation of Four Methods of Sorghum Grain Processing¹

Texas A&M University, College Station 77843

Abstract

Two feeding trials were conducted in commerical feedlots of West Texas to study the influence of four grain processing methods upon animal performance and carcass characteristics. Steers fed steam flaked, whole reconstituted and rolled or rolled reconstituted sorghum grain rations (Trial I) gained at similar rates and also produced carcasses with similar characteristics. Similar results were observed for steers fed either steam flaked or micronized sorghum grain rations (Trial II).

In Trial I steers fed whole reconstituted and rolled grain rations consumed less feed than the other two treatments resulting in a more desirable feed conversion. In Trial II steers fed micronized grain rations consumed slightly more feed than those fed steam flaked grain rations and showed less desirable feed conversion. Physical characteristics of the processed grains are described.

The authors wish to express their appreciation to the management of both commercial feedlots, their staffs, other individual cooperators and the Texas Agricultural Extension Service for making these field studies possible.
