Abstract
Felista Mwangi investigated the effect of supplementing tropical beef cattle with desmanthus on performance and meat quality. She found that desmanthus can maintain animal weight gain and plasma metabolite profile without negatively affecting carcass traits and meat quality. Additionally, she identified genetic markers in lipogenic genes for carcass and meat quality improvement. Beef cattle producers are using the results of her study.
