Transcriptome analyses reveal reduced hepatic lipid synthesis and accumulation in more feed efficient beef cattle [PDF]

open access: yes, 2018
peer-reviewedThe genetic mechanisms controlling residual feed intake (RFI) in beef cattle are still largely unknown. Here we performed whole transcriptome analyses to identify differentially expressed (DE) genes and their functional roles in liver ...

Differences in intestinal size, structure, and function contributing to feed efficiency in broiler chickens reared at geographically distant locations [PDF]

open access: yes, 2019
The contribution of the intestinal tract to differences in residual feed intake (RFI) has been inconclusively studied in chickens so far. It is also not clear if RFI-related differences in intestinal function are similar in chickens raised in different ...

Residual feed intake in dairy ewes: an evidence of intraflock variability [PDF]

open access: yesAnimals, 2019
Abstract This study examined the intraflock variability of feed efficiency in dairy ewes, through monitoring residual feed intakes (RFI). Primiparous lactating ewes ( n =43; 57.7±0.91 kg body weight [BW] at lambing), representative of a French Lacaune dairy flock, were allocated in ...

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

open access: yesAnimals, 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.

The influence of feeding behaviour on growth performance, carcass and meat characteristics of growing pigs [PDF]

open access: yes, 2018
This study investigated the effect of the feeding behaviour on growth performance, and car- cass and meat characteristics of 96 barrows fed ad libitum or restrictively with high or low amino acids (AA) diets according to a 2 7 2 factorial design.

Invited review: Improving feed efficiency in dairy production: challenges and possibilities*

open access: yesAnimal, 2015
Despite substantial advances in milk production efficiency of dairy cattle over the last 50 years, rising feed costs remain a significant threat to producer profitability.

Feed efficiency and surplus feed intake among Norwegian Red dairy cows

open access: yesJournal 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

Growth performance, carcass traits, meat quality, and blood variables of small-sized meat ducks with different feed efficiency phenotypes

open access: yesPoultry Science, 2023
: The study investigated the effects of feed efficiency (residual feed intake, RFI and residual intake and gain, RIG) on the production performance of small-sized meat ducks.
