This work was conducted with the objective of verifyingthe effects of increasing the corn silage harvest height from 16 to46 cm, associated to 16 or 30% of concentrate level on total drymatter offered, on carcass and meat characteristics of young steers.Twenty-four Braford calves, weaned at three months of age, werefinished in feedlot from seven to twelve months, when they wereslaughtered. The commercial carcass cuts, metric carcass measurements,such as the bone, muscle and fat percentages and carcasstissues ratios were not affected by the silage harvest height anddiet concentrate level used. On the other hand, meat of steers fedwith low concentrate level had lower thawing loss (5.05 vs. 8.03%)resulting in higher juiciness (7.14 vs. 6.74 points), although themeat showed darker coloration than the meat of the other steers(3.17 vs. 4.00 points). The comparison between harvest heightsshowed that meat of steers fed with silage harvested at 16 cm fromthe soil had higher juiciness (7.18 vs. 6.69 points), as the resultshowed lower thawing loss (4.70 vs. 8.38%) and lower cookingloss (17.11 vs. 22.33%).
