Abstract: This work was carried out to evaluate animal performance and carcass characteristics of 45 young bulls of three genetic groups: Nellore, 1/2 Nellore × 1/2 European and 1/4 Nellore × 3/4 European finished in feedlot. At the beginning of feedlot, the average bull was 20 (±2) months old, and average weight body was 356.0 (±7.9) kg. The 1/2 Nellore × 1/2 European young bulls had greater (P b 0.05) initial weight (381.7 kg), final weight (531.6 kg) and hot carcass weight (279.2 kg) than 1/4 Nellore × 3/4 European a… Show more

“…The rump presented 32.5% more cholesterol than the loin. Cholesterol values found in this study (30.9 and 40.1 mg 100 g -1 for loin and rump, respectively) were lower than the values considered normal (58.3 to 83.4 mg 100 g -1 ) for different beef cuts (Macedo et al, 2008;Maggioni et al, 2010;Rotta et al, 2009).…”

“…The greater carcass length for crossbred bulls can be explained by the effect of breed. European cattle have a higher carcass length when compared to Zebu cattle (Maggioni et al, 2010;Rotta et al, 2009). However, leg length was similar (p > 0.05) for the bulls from the two genetic groups.…”

“…In recent years, several studies aiming to evaluate the effects of feed (Fugita et al, 2012;Zawadzki et al, 2011;Valero et al, 2011;Sun et al, 2009;Fernandes et al, 2009;Jorge et al, 2009;Kazama et al, 2008;Silva et al, 2002;Prado et al, 2008b), genetic groups (Ito et al, 2012;Maggione et al, 2009;Rossato et al, 2009;Ducatti et al, 2009;Oliveira et al, 2009;Orellana et al, 2009;Abrahão et al, 2008;Prado et al, 2008a;2008c;2008d), sex (Prado et al, 2009a;2009b;Aricetti et al, 2008, Kuss et al, 2006, slaughter age (Ito et al, 2010), effect of a Luteinizing Hormone-Releasing Hormone (LHRH) fusion protein vaccine vs. surgical castration (Ruiz et al, 2005) and the anatomical location of muscles on meat quality in cattle, quantified the total fat, using gravimetric methods. It has been observed that, in general, if the objective is, beyond the quantification of total lipids, the quantification of fatty acids of meat lipids, mainly of polyunsaturated lipids, the methods used by researchers involve extracting lipids and sampling the "fresh" ones with solvents at room temperature.…”

“…Although recommended for extracting lipids from samples with high water content and low in fat, Maggione et al (2009) and Kuss et al (2006), used the method of Folch et al (1957) with modifications, to extract lipids from beef samples submitted to pre-drying in a forced air oven at 55°C. After the separation of the solvents, the organic layer containing chloroform was subjected to a water bath at 40°C, under a flow of compressed air, in both cases.…”
