| This trial aimed to evaluate the inclusion of 10% of crude glycerin associated with roughage sources on the quality of meat aged for 1, 7 or 14 days post mortem of Nellore young bulls. Thirty feedlot animals (n = 10) with initial body weight of 416.70 ± 24.74 kg and 18 months of age were assigned to three treatments: corn silage (CS), sugar cane (SC) and sugar cane bagasse (CB), using a completely randomized design. After 85 days of feeding, animals were slaughtered with 554.51 ± 38.51 kg. Samples of longissimus muscle were collected, after carcass chilling, and vacuum-packed. Diets influenced pH, meat color and subcutaneous fat (SF) (p > 0.05). Animals fed CS showed higher values of b* in SF (p < 0.05). Differences were not found in the meat fatty... |
