Rice Milling Coproducts as Feedstuffs for Beef Cattle

The objective of this paper was to collectively present literature on the performance, intake, and digestibility of diets containing rice milling coproducts. Rice milling coproducts may be an economical alternative feedstuff in the south-central United States and California; however, limited studies have been published in peer-reviewed journals on the utilization of rice milling coproducts within the United States. Most published research about rice milling coproducts were conducted outside the United States and application of results within the United States may be difficult due to basal dietary differences. Performance between cattle supplemented with corn and rice bran or de-oiled rice bran have been variable. Part of this variability may be due to variation in the nutrient composition of the rice bran among studies and regional differences due to milling procedures and rice varieties. Variability in performance results of rice bran and de-oiled rice bran and limited research with forages and feedstuffs common to the United States warrants a further investigation into how rice milling coproducts can be effectively used in cattle diets in the United States.
