Residual feed intake and blood variables in young Nellore cattle
Journal of Animal Science, 2015This study was conducted to evaluate associations of performance traits, feed efficiency, and blood variables with residual feed intake (RFI) in growing Nellore cattle. A total of 118 growing Nellore animals, 62 males and 56 females, were used. A diet containing 2 Mcal/kg was offered ad libitum and individual DMI was measured over a period of 84 d ...

Investigation of Residual Feed Intake in Dairy Cows
2013This thesis research was aimed to develop a residual feed intake (RFI) prediction equation in dairy cattle while accounting for the animals’ multifunctional lactation non-linear energy requirements profiles. The possibility of shortening RFI test period and finding indicator traits for RFI selection were also investigated.

Residual feed intake and breeding approaches for enteric methane mitigation.
2015Abstract The expanding world human population will require greater food production within the constraints of increasing societal pressure to minimize the resulting impact on the environment. Breeding goals in the past have achieved substantial gains in environmental load per unit product produced, despite no explicit inclusion of environmental ...

Because feed is the major input in pork production, conversion of feed into lean tissue at minimum costs has been a focus for improvement. Several researchers have proposed using residual feed intake (RFI) rather than feed conversion ratio (FCR) for genetic improvement of feed efficiency. Little is known about the variation in RFI in pigs.
