During recent years the beef industry has undergone vast changes. These have been made necessary in part by economic conditions and in part by changes in the demands of the American people. The tendency has been toward earlier marketing of steers, so that instead of going to the block as mature individuals at from 3 to 5 years of age, they are now reaching the market at a much younger age. In consuming centers where only heavy carcasses of beef were demanded formerly there is a call today for carcasses of the yearling and long yearling class.
The experiments reported in this bulletin cover a 4-year period from October, 1920 to May, 1924. There were 4 trials, each beginining in October and ending in May. This series of trials were carried on with the object of ascertaining what steers of similar breeding but of different ages would do when fed under like conditions.
