¹Slick-cattle managed with slick bunk feed protocol, adlib-cattle had access to ad libitum feed, all–all groups were combined.

²Forward-records were split into the first F7, F14, F21, F28, F35, F42, F49, F56, F63, and F70 d of the test and reverse-records were split into the last R7, R14, R21, R28, R35, R42, R49, R56, R63, and R70 d of the test.
