Nutritional Benefits of Specialty Grain Hybrids in Beef Feedlot Diets

摘要

The study of grain hybrids with faster or more extensive rates of ruminal starch fermentation has been a key research area. Because grain sorghum starch is generally regarded as less accessible to en- zymatic degradation than starch in other grains, it has received the greatest research emphasis. However, all grains have been evaluated to some Extent. Grain sorghum hybrids appear to be more Variable in digestibility, in vitro and in vivo, and in Rate of starch fermentation than are corn hybrids.
