Current Research Projects
Maternal and neonatal nutrition and skeletal muscle development of the offspring
Duarte's laboratory is currently investigating the impact of gestational and neonatal nutrition on the skeletal muscle development of offspring in meat animals. A key focus of this research involves the examination of how maternal nutrition influences the mechanisms associated with myogenesis and adipogenesis in skeletal muscle, and the potential implications for the animal's performance, carcass deposition, and meat quality. Gaining insight into the intrinsic and extrinsic effects of maternal nutrition during gestation on the trajectory of an animal's life has the potential to enhance nutritional management in the early stages, ultimately leading to improvements in carcass yield and quality.
Supplementation of functional amino acids to enhance muscle growth and development
The current body of research exploring the effects of industrial amino acids (AA) and intermediary molecules of AA metabolism on the mechanisms influencing muscle growth and development in beef cattle is rather sparse. Notably, a substantial knowledge gap exists in understanding how these functional molecules can be strategically integrated into beef production practices. In response to this gap, our laboratory is actively engaged in the strategic utilization of functional amino acids, employing a combined approach that merges fundamental and applied science. Our aim is to unravel the intricate biology of muscle growth, discerning its impact on carcass yield, and elucidating potential implications for quality traits.
