Kansas Agricultural Experiment Station Research Reports

Objective:The objective of our experiment was to evaluate the effects of bunk allotment on performance of growing beef calves during a 58-day receiving period and investigate possible residual effects of bunk-space allotment on subsequent growth performance during a 90-day grazing season.

Study Description:A group of 385 crossbred steers (initial weight 473 ± 56 lb) were purchased in Texas and transported to the Kansas State University Beef Stocker Unit. Calves were blocked by arrival date, assigned to one of four bunk space treatments (i.e., 10, 15, 20, or 25 in of bunk per head), and limit-fed a high-energy corn …
