Protein turnover and infrared thermography in Nellore bulls classified for residual feed intake

  • Chapter
Energy and protein metabolism and nutrition in sustainable animal production

Abstract

Residual feed intake (RFI), the difference between actual and expected intake, is an efficiency trait that is independent of BW and BW gain. The RFI might be related to a lower protein turnover and a lower heat production in efficient animals (Arthur et al., 2004). The aim of this study was to evaluate the relationship of RFI with protein turnover and temperature of eyes and skin.
