Genome wide association study of growth and feed efficiency traits in rabbits
World Rabbit Science, 2023 Feed efficiency is a major production trait in animal genetic breeding schemes. To further investigate the genetic control of feed efficiency in rabbits, we performed a genome-wide association study (GWAS) for growth and feed efficiency on 679 rabbits ...

Effects of host genetics and environmental conditions on fecal microbiota composition of pigs. [PDF]
PLoS ONE, 2018 Since microbiota may influence the physiology of its host including body weight increase, growth rate or feed intake, in this study we determined the microbiota composition in high or low residual feed intake (HRFI and LRFI) pig lines, of different age ...

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 in beef cattle
Revista Brasileira de Zootecnia, 2008 Providing feed is a major input cost in beef production, hence improvements in the efficiency of feed utilisation will reduce the cost of production. Residual feed intake (RFI) is a measure of feed efficiency, and is defined as the difference between an ...

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 ...

Phenotypic and Genetic Correlations of Feed Efficiency Traits with Growth and Carcass Traits in Nellore Cattle Selected for Postweaning Weight. [PDF]
PLoS ONE, 2016 This study evaluated phenotypic (rph) and genetic correlations (rg) between 8 feed efficiency traits and other traits of economic interest including weight at selection (WS), loin-eye area (LEA), backfat thickness (BF), and rump fat thickness (RF) in ...

New residual feed intake criterion for longitudinal data
Genetics Selection Evolution, 2021 Background Residual feed intake (RFI) is one measure of feed efficiency, which is usually obtained by multiple regression of feed intake (FI) on measures of production, body weight gain and tissue composition.

Genetic parameters for performance, feed efficiency, and carcass traits in Senepol heifers
Animal, 2021 Improving feed efficiency is a key breeding goal in the beef cattle industry. In this study, we estimated the genetic parameters for feed efficiency and carcass traits in Senepol cattle raised in tropical regions.
