Abstract

The objective of this proposal is to publish scientific papers related to novel insights on Nellore beef cattle production and training Dr. Leandro Sannomiya Sakamoto in works with methane emission in vivo and in vitro. In addition, the knowledge and training will be key for the development of new research projects to be conducted in Brazil with Nellore cattle. The research will be focused on enteric methane mitigation strategies, mainly feed efficiency (residual feed intake - RFI), whereas the adoption of RFI as selection criteria has extreme worldwide relevance given the need of production techniques to optimize feed utilization by beef animals and reduce environmental impacts of the activity. The use of RFI as selection criteria has been studied in the past decades. However, inconsistent data are still reported in studies with Nellore breed, evidencing the need for further research. Our objectives are (1) to determine the differences in methane enteric emission of Nellore cattle classified by RFI; (2) to elucidate the associations between RFI and enteric methane; and (3) to study enteric methane mitigation strategies. In order to achieve these results, the student will work with Dr. Nicolas DiLorenzo at University of Florida, on a dataset from Instituto de Zootecnia - IZ, Sertãozinho - SP, Brazil. In addition, during the abroad internship, the student will participate in in vivo enteric methane mitigation studies and will receive training in in vitro procedure technique. Thus, by the end of the internship, the student will contribute to nationwide livestock development, visibility and impact of the Brazilian science. (AU)
