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 F14, F28, F42, F56, and F70 d of the test and reverse-records were split into the last R14, R28, R42, R56, and R70 d of the test.
