¹ADG, average daily gain.

²DD, digital dermatitis; FR, foot rot.

³Reference group used for comparisons.

⁴FPH, fall-placed heifer; WPH, winter-placed heifer; FPS, fall-placed steer; WPS, winter-placed steer.

⁵Pen condition: 1=dry, 2=more bedding than mud, 3=more mud than bedding, and 4=excessive mud.
