ACADEMIC & RESEARCH INTEREST

Dr. de Mello's research focus on positively impact meat industry operations, production costs, meat quality attributes, and animal welfare.

Current research topics include pre and post-harvest food safety interventions, effects of feeding different sources of energy on meat composition, shelf life stability, added value-fresh cuts, and effects of physiologic parameters on muscle-to-meat transformation.

Effects of different antioxidants on quality of beef patties from steers fed low-moisture distillers grains
Corn Distillers Grains plus Solubles (DGS) are commonly used as a source of protein and energy for finishing cattle and its composition may vary based on moisture levels, fat and protein content. However, the inclusion of DGS in finishing diets alters beef quality attributes when compared to corn-based diets.
