Descrição: dc.descriptionFourteen Nellore and 14 Angus young bulls with BW of 381 ± 11.8 kg were randomly assigned into 2 feeding groups (whole shelled corn without forage (WSC) or corn silage and ground corn (GC)) to evaluate chemical composition and expression of genes involved in lipid metabolism in the longissimus thoracis (LT). We hypothesized that bulls fed the WSC diet have greater amounts of intramuscular fat and Angus have higher expression levels of PPAR and SREBF. Meat from Angus bulls had greater ether extract compared to Nellore (P < 0.05). Muscle from bulls fed the WSC diet had greater expression of PPARA (P < 0.05) and lower levels of SREBF1 expression (P < 0.01). The LT of Nellore fed GC had greater expression of FABP4, ACACA and SCD genes (P < 0.01). In conclusion, the greater concentration of starch in the WSC diet did not increase marbling in the beef of bulls fed this diet due to the reduced expression of SREBF1.-
