Genome-wide association analysis of feed intake and residual feed intake in Nellore cattle [PDF]

BMC Genetics, 2014
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.

Novel genetic parameters for genetic residual feed intake in dairy cattle using time series data from multiple parities and countries in North America and Europe [PDF]

Journal of Dairy Science, 2023
: Residual feed intake is viewed as an important trait in breeding programs that could be used to enhance genetic progress in feed efficiency. In particular, improving feed efficiency could improve both economic and environmental sustainability in the ...

Residual feed intake: A limiting economic factor for selection in poultry breeding programs

Annals of Agricultural Sciences, 2021
The recent breeding programs for livestock and poultry projects have aimed at maximizing productivity and minimizing gross costs. It is well known that feed represents the main variable component affecting the productive process.

Residual Feed Intake [PDF]

, 2004
IntroductionLow rates of return on investment for livestock operations are a fact of life. Producers have little impact on the market price for their cattle; therefore management must be focused on the things producers can actually do something about.

Full-lactation performance of multiparous dairy cows with differing residual feed intake.

PLoS ONE, 2022
Residual feed intake (RFI) is an efficiency trait underpinning profitability and environmental sustainability in dairy production. This study compared performance during a complete lactation of 36 multiparous dairy cows divided into three equal-sized ...

Pedigree and genomic analyses of feed consumption and residual feed intake in laying hens

Poultry Science, 2013
Efficiency of production is increasingly important with the current escalation of feed costs and demands to minimize the environmental footprint. The objectives of this study were 1) to estimate heritabilities for daily feed consumption and residual feed intake and their genetic correlations with production and egg-quality traits; 2) to evaluate ...

Analysis of Body Weight and Feed Intake Curves in Selection Lines for Residual Feed Intake in Pigs

, 2009
A selection experiment for reducing residual feed intake (RFI= feed consumed over and above expected requirements for production and maintenance) in Yorkshire pigs consists of a line selected for lower RFI (LRFI) and a random control line (CTRL). Using 64 LRFI and 87 CTRL boars from generation 5 of the selection experiment, cubic polynomial random ...

Inclusive inheritance for residual feed intake in pigs and rabbits [PDF]

Journal of Animal Breeding and Genetics, 2020
AbstractNon‐genetic information (epigenetic, microbiota, behaviour) that results in different phenotypes in animals can be transmitted from one generation to the next and thus is potentially involved in the inheritance of traits. However, in livestock species, animals are selected based on genetic inheritance only.

Genomic Regions Associated with Feed Efficiency Indicator Traits in an Experimental Nellore Cattle Population. [PDF]

PLoS ONE, 2016
The objective of this study was to identify genomic regions and metabolic pathways associated with dry matter intake, average daily gain, feed efficiency and residual feed intake in an experimental Nellore cattle population.

Genetic Parameters for Different Measures of Feed Efficiency and Their Relationship to Production Traits in Three Purebred Pigs

Life, 2021
Residual feed intake (RFI) gained attention as a potential alternative to the feed conversion ratio (FCR). Thus, this study aimed to estimate genetic parameters for different feed efficiency (FE) traits (FCR, RFI1 to RFI5) and their genetic correlation ...
