Residual feed intake in beef cattle [PDF]

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 ...

New residual feed intake criterion for longitudinal data [PDF]

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.

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.

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.

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 ...

Comparison of 3-breed rotational crossbreds of Montbéliarde, Viking Red, and Holstein with Holstein cows fed 2 alternative diets for dry matter intake, production, and residual feed intake

Journal of Dairy Science, 2022
: The objective of this study was to compare 3-breed rotational crossbred (CB) cows of the Montbéliarde, Viking Red, and Holstein (HO) breeds with HO cows fed 2 alternative diets for dry matter intake (DMI), fat plus protein production (CFP), body weight

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 ...

Water requirements of beef production can be reduced by genetic selection

Animal, 2021
Growing concerns regarding sustainability in agriculture include the availability of drinking water, which is putting pressure on livestock production, especially the beef sector, for more efficient practices.

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.

Protein synthesis and degradation gene SNPs related to feed intake, feed efficiency, growth, and ultrasound carcass traits in Nellore cattle. [PDF]

, 2018
We looked for possible associations of SNPs in genes related to protein turnover, with growth, feed efficiency and carcass traits in feedlot Nellore cattle.
