Multi-omics profiling of hepatic macromolecules in laying hens with difference feed intake: Mechanistic insights into antioxidant capacity modulation [PDF]
Poultry ScienceCurrently, the cost of poultry feed accounts for more than 70 % of the total cost of poultry production. Therefore, it is crucial to find appropriate strategies to reduce feed cost and improve feed efficiency in livestock genetic improvement programs ...

Temperament and performance of Nellore bulls classified for residual feed intake in a feedlot system [PDF]
Anais da Academia Brasileira de Ciências, 2020 This study aimed to evaluate the performance in feedlot and temperament of Nellore bulls classified by residual feed intake. The residual feed intake was calculated as the difference between the observed and predicted dry matter intake.

Methane, growth and carcase considerations when breeding for more efficient Merino sheep production
Animal, 2023 Feed intake, methane and feed efficiency have important genetic correlations with growth, carcase weights and mature size that need to be considered when breeding for production whilst reducing feed requirements and methane production in the Australian ...

Genetics of feed intake traits in Czech Large White pig population [PDF]
Acta Fytotechnica et Zootechnica, 2020 Feed represents a substantial proportion of the variable costs of pig production. Feed efficiency is traditionally expressed as the feed conversion ratio (FCR) and more recently as residual feed intake (RFI).

Impacts of stress-induced inflammation on feed intake of beef cattle
Frontiers in Animal Science, 2022 Livestock animals are often exposed to unavoidable stressful situations during their productive life that triggers stress-induced inflammatory responses, which are known to influence their nutrient requirements and feed intake.
