Background The feed conversion ratio (FCR) and residual feed intake (RFI) are common indexes in measuring feed efficiency for livestock. RFI is a feed intake adjusted for requirements for maintenance and production so these two traits are related ...

A procedure to quantify the feed intake response of growing pigs to perturbations
Improving robustness of farm animals is one of the goals in breeding programmes. However, robustness is a complex trait and not measurable directly. The objective of this study was to quantify and characterize (elements of) robustness in growing pigs ...

Genome-wide association analysis of feed intake and residual feed intake in Nellore cattle [PDF]
Feed intake plays an important economic role in beef cattle, and is related with feed efficiency, weight gain and carcass traits. However, the phenotypes collected for dry matter intake and feed efficiency are scarce when compared with other measures such as weight gain and carcass traits.

THE PERFORMANCE OF LAYING HENS FED DIFFERENT CALCIUM SOURCE [PDF]
The research was aimed to evaluate the performance of laying hens fed different calcium sources. Two hundreds of Isa Brown laying hens were used in this study. The hens were raised in individual battery cages units for 12 weeks.

Temperament and performance of Nellore bulls classified for residual feed intake in a feedlot system [PDF]
This study aimed to evaluate the performance in feedlot and temperament of Nellore bulls classified by residual feed intake. The residual feed intake was calculated as the difference between the observed and predicted dry matter intake.

Methane, growth and carcase considerations when breeding for more efficient Merino sheep production
Feed intake, methane and feed efficiency have important genetic correlations with growth, carcase weights and mature size that need to be considered when breeding for production whilst reducing feed requirements and methane production in the Australian ...
