(2012-10-19)Residual feed intake (RFI) is one method to identify feed efficient animals; however, this method is costly and time consuming therefore, identifying an indirect measure of RFI is important. Evaluating the glucoregulatory ...
-
(2010-10-12)These studies were designed to evaluate the relationships between residual feed intake (RFI) and performance of growing heifers and Brahman cows. Residual feed intake was determined for 77 heifers of diverse breedtypes ...
-
(2011-01-11)Identification of feed efficient cattle by determination of residual feed intake (RFI) of individual animals is both laborious and expensive (negative RFI value=efficient; positive RFI value=inefficient). A less costly ...
-
(2010-10-12)Objectives of this study were 1) to characterize the relationship between beef cattle efficiency, namely residual feed intake (RFI), and digestive, microbial, and fermentation parameters in growing beef calves and 2) to ...

(Texas A&M University, 2006-04-12)Objectives of this study were to determine if variation in energy expenditures contributed to differences in feed efficiency between low and high RFI steers. Nine steers with the lowest and highest residual feed intakes ...
