Mouthing a two tooth grass-fed Murray Grey heifer prior to sale. The age of cattle is determined chiefly by examination of the teeth, and less perfectly by the horn rings or the length of the tail brush; due to bang-tailing, which is the act of cutting the long hairs at the tip of the tail short to identify the animal after management practices, the last method is the least reliable.
The United States grades feeder cattle that have not reached an age of 36 months on three factors: frame size, thickness, and thriftiness. [7]Frame size evaluates feeder cattle' height and body length as determined by their skeletal size in relation with their age; frame size affects the animals' mature size and weight gain composition as they are fed into fed cattle.
