Summary: Growing concerns about the availability of drinkable water have increasingly pushed pressure on livestock production. Thus, the objective of this study was to evaluate the residual water intake (RWI) as an indicator of water use efficiency in beef cattle and its relationship with water consumption, feed intake, feed efficiency and growth. Records on 749 Senepol heifers, of approximately 17 months of age, involved in feedlot performance tests, were used. Traits studied included body weight (BW), RWI, residual feed intake (RFI), average daily feed intake (ADFI), average daily water intake (ADWI), average daily gain (ADG) and feed conversion ratio (FCR).
