CATTELAM, Jonatas et al. Carcass characteristics and meat quality of feedlot steers finished in different individual spaces. Ciênc. anim. bras. [online]. 2013, vol.14, n.2, pp.185-198. ISSN 1809-6891.

The objective of this study was to evaluate the meat and carcass characteristics of feedlot steers finished in different individual spaces. We used 48 steers, with average initial age and weight of 20 months and 243.4 kg, respectively. The animals were placed in collective stalls and distributed into treatments according to the available individual space, 2.5; 5.0 and 10 m2. The diet contained roughage:concentrate relation of 39:61 (dry matter basis). Individual spaces did not influence hot and cold carcass weight, means of 226.0 and 222.1 kg, respectively, as well their respective carcass dressing, 58.5 and 57.0 kg/ 100 kg live weight. For all treatments, the carcasses showed the minimum fat thickness required, 3 mm, being similar among the different individual spaces evaluated. The weight and percentage of commercial cuts, the absolute weight and the tissue participation in the carcass were similar among the individual spaces. The pH and temperature in Longissimus dorsi and Recto femoralis muscles were not altered by individual spaces. Color, texture, marbling, and the meat sensorial characteristics (tenderness, juiciness and palatability) were not influenced by different individual spaces. The shear force showed mean of 5.06 kgF/cm3. The number of lesions, location and time of occurrence was not influenced by different individual space. The individual space for feedlot steers during finishing did not influence carcass and meat characteristics, when slaughtered at 24 months of age.
