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 ...

Impact of heat stress on dry matter intake and residual feed intake in midlactation dairy cows.

Journal of Dairy Science
The rise in global temperature is affecting livestock production by limiting crop yields and exposing animals to more frequent heat-stress events. Heat-abatement technologies are widely used but increase production costs. Therefore, genetic selection for

Feature Selection Stability and Accuracy of Prediction Models for Genomic Prediction of Residual Feed Intake in Pigs Using Machine Learning

Frontiers in Genetics, 2021
Feature selection (FS, i.e., selection of a subset of predictor variables) is essential in high-dimensional datasets to prevent overfitting of prediction/classification models and reduce computation time and resources.

Feed efficiency and surplus feed intake among Norwegian Red dairy cows

Journal of Dairy Science
: Feed in livestock production is a major cost driver and closely linked to GHG emissions from the sector. Hence, there is a great deal of interest to improve feed efficiency of livestock and promote economic and environmental sustainability of livestock

Genome-Wide Association Study of Feed Efficiency Related Traits in Ducks

Animals, 2022
Feed efficiency (FE) is the most important economic trait in the poultry and livestock industry. Thus, genetic improvement of FE may result in a considerable reduction of the cost and energy burdens.

Effects of residual feed intake on the economic traits of fast-growing meat ducks

Poultry Science
Feed efficiency (FE) is a crucial economic indicator of meat duck production. The objective of this study was to assess the impact of residual feed intake (RFI), defined as the difference between the actual and expected feed intake based on animal's ...

Common and diet-specific metabolic pathways underlying residual feed intake in fattening Charolais yearling bulls

Scientific Reports, 2021
Residual feed intake (RFI) is one of the preferred traits for feed efficiency animal breeding. However, RFI measurement is expensive and time-consuming and animal ranking may depend on the nature of the diets.

Feed efficiency estimation from stochastic feed requirement frontier

Journal of Dairy Science
: Feed accounts for 40% to 70% of livestock production cost. Therefore, improving feed efficiency of production animals will promote farm profitability. To this end, precise estimation of animal level feed efficiency is important.
