This study evaluated animal performance, carcass characteristics and meat quality of 36-month old Nellore steers finished in pastures (n = 10) and 20-month old Angus vs. Nellore bulls finished in feedlot (n = 10). Final body weight, carcass weight, characteristics, conformation and fat thickness, were higher (p &lt; 0.001) for the Nellore steers than for Angus vs. Nellore bulls. Water losses during chilling (24 hours, 4oC) were lower (p &lt; 0.05) for Nellore steers than for the Angus vs. Nellore bulls. Muscle percentage on the 6th rib was higher (p &lt; 0.05) for the Nellore steers than for Angus vs. Nellore bulls; while bone percentage was lower (p &lt; 0.05) for Nellore steers. After 7 and 14 days of ageing, the L* meat value was higher for the Nellore...

Slaughter weight did not alter carcass characteristics and meat quality of crossbred heifers supplemented and finished in a pasture system
Provedor de dados: 2

This work was carried out to evaluate the animal performance, carcass characteristics and meat quality of crossbred heifers slaughtered at three different body weights. The heifers were slaughtered with 330 (Light), 360 (Medium) and 400 (Heavy) kg body weight. The final weight, average daily gain and carcass weight were greater for HEA heifers, intermediate for MED heifers and lower for LIG heifers. However, carcass dressing and pH were similar for the three heifers groups. Dripping loss, dissection loss and the muscle, fat and bone percentages on the 6th rib did not alter by slaughter weight. Slaughter weight did not affect the colour, shear force and lipid oxidation of meat. In conclusion, heavy heifers finished in pasture and that were...

Concentrate levels of crossbred bulls slaughtered at 16 or 22 months: performance and carcass characteristics
Provedor de dados: 2
Autores: Pinto, Adriana; Passetti, Rodrigo Augusto Cortêz; Guerrero, Ana; Rivaroli, Dayane Cristina; Perotto, Daniel; Prado, Ivanor Nunes do.
This study was performed to assess the animal performance of 97 bulls, ½ Purunã vs. ½ Canchim, that were slaughtered at 16 (16M) or 22 (22M) months with three concentrate levels (0.8, 1.2, and 1.6%) of body weight (BW). The initial body weight was lower for the 16M bulls. The final body weight and hot carcass weights were similar between the two slaughter ages. The hot carcass dressing was higher for 22M bulls. The average daily gain was higher for 16M bulls. The feed intake and dry matter feed conversion were similar between 16 and 22M bulls. The carcass length, marbling, and bone percentage were lower for 16M bulls. However, the Longissimus dorsi muscle area was higher for 16M bulls. The leg length, cushion thickness, fat thickness, conformation, colour,...

How does the dietary cottonseed hull affect the carcass characteristics and meat quality of young bulls finished in a high-concentrate diet?
Provedor de dados: 2
Autores: Eiras, Carlos Emanuel; Ornaghi, Mariana Garcia; Valero, Maribel Velandia; Rivaroli, Dayane Cristina; Guerrero, Ana; Prado, Ivanor Nunes do.
This study evaluated the effects of diets composed by cottonseed hull and meat aging on carcass characteristics and meat quality from young bulls fed on a high-concentrate system. Thirty crossbred bulls were assigned in a complete randomized experimental factorial design with three diets (CH21: cottonseed hull 210 g kg-1on a DM basis, CH27: cottonseed hull 270 g kg-1on a DM basis and CH33: cottonseed hull 330 g kg-1on a DM basis) and different aging times (24 hours and 3, 7 and 14 days). Meat from CH27 diets presented smaller LM moisture content (p &lt; 0.05). Total lipids were smaller in CH33 diet (p &lt;0.05). At 24 hours, CH21 diet presented smaller LM cooking loss than other diets. The increasing aging time reduced the shear force (p &lt; 0.001) on the...
