Dr. Luis O. Tedeschi has gained international recognition for his growth and bioenergetic research and decision-support system in ruminants to help stakeholders achieve profitable animal production. Since the 1990s, Tedeschi has published 282 peer-reviewed manuscripts, 76 editor-reviewed manuscripts, 42 books or book chapters, and more than 289 abstracts, totaling more than 732 scientific publications on the impact of the composition of growth of growing cattle. He postulated that an animal’s body gain composition to its energy deposition efficiency in beef cattle’s tissues rather than the traditional dietary components approach. His forward-thinking approach to partitioning energy in growing cattle led him to develop the fundamentals and calculation logic behind a computer model used to determine the necessary days on feed to achieve the maximum profit for group-fed animals. Tedeschi has received numerous praises from feedlot-related enterprises for his computer models and books.
