Fig. 2. Comparison of empirical cumulative distribution functions of partial returns per cow for steer calves born in 2000 through 2002 and sold at time of weaning (Panel A = Weaning) vs. time of feedlot placement (Panel B = Feedlot) and time of finish (Panel C = Finish). Production systems are defined by the number of paddocks and implies rotation frequency (2 is rotating twice monthly and 8 is rotating twice weekly) whereas the letter represents early (E) weaning in April vs. 56 d later (L). The number of observations is presented in parentheses for each production system. PR = partial returns.
