Abstract
Commodities are a necessary purchase in cattle feeding operations; however, due to market fluctuations, costs may increase having a negative impact on the economic efficiency of such operations. Steers recently arrived at feedlot facilities are generally offered diets with elevated inclusions of forages and other commodities. These receiving diets are formulated to transition cattle to a high-grain diet. The receiving period influences performance and is an important phase prior to finishing. Stress can negatively impact cattle performance during the receiving phase, in which molasses may have the potential to mitigate stressors associated with transportation. Additionally, molasses can increase nutrient utilization by improving fiber degradation and has the potential to mitigate methane emissions. The objective of this study is to evaluate the effects of replacing soybean hulls with molasses in the receiving diets of beef steers on performance, nutrient digestibility, enteric methane emissions, blood inflammatory marker, and ruminal fermentation.
