Effect of Growth Path on the Tenderness of the semitendinosus Muscle of Brahman-cross Steers

摘要

The growth paths of 36, nine-month-old Brahman-cross steers were modified to determine the effect of their growth history on tenderness of the semitendinosus (ST) muscle. Steers were assigned to one of three treatment groups. One group of steers (uninterrupted group) was grazed on improved tropical pasture for 257 days and had an average weight gain of 0.6 kg day~-1. The other two groups were fed a restricted diet of low-quality grass hay and lost on average - 13 /100 of their initial live weight over 100 days.
