Federally inspected cattle dressed weights averaged 843 pounds in November. Average dressed weights increased annually for the last 5 years, and since 2011, have been up more than 9 percent. However, the rate of increase slowed in 2016, with all cattle dressed weights through November averaging about the same as year-earlier weights for the same period.
Heifer weights increased during this period, but steer weights and cow weights were lower. In addition to genetic advancements and efficiency gains, cattle weights are influenced by feed prices and the price for fed cattle. Since 2014, low feed prices have helped drive more rapid weight gains in recent years.
Additionally, tighter supplies of cattle in 2014 and 2015 put pressure on producers to increase weights. In 2016, cattle numbers rebounded slightly. This recovery potentially reduced the need for added weight per animal. This chart appears in the ERS Livestock Dairy and Poultry Outlook report released in January 2017.
