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.

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 ...

Phenotypic evaluation of feed efficiency, growth and carcass traits in native turkeys [PDF]

Journal of Central European Agriculture, 2023
Improving feed efficiency decreases feed intake, total cost, and the environmental emission of poultry production. This study aimed to investigate different feed efficiency, growth and carcass traits between high and low feed efficiency birds in Iranian ...

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 ...

Effects of Feeding and Drinking Behavior on Performance and Carcass Traits in Beef Cattle

Animals, 2022
Feed and water efficiency are important traits to improve beef cattle production’s economic and environmental sustainability. This study evaluated residual feed intake (RFI) and residual water intake (RWI) and their relationship with performance ...

Alterations in nutrient digestion and utilization associated with different residual feed intake in Hu sheep

Animal Nutrition, 2023
Improving feed efficiency is crucial to the animal industry. Residual feed intake (RFI) is now regarded as an index of feed efficiency evaluation and is independent of growth characteristics.

Association of residual feed intake with intestinal microbiome and metabolome in laying period of ducks

Frontiers in Microbiology, 2023
Introduction Residual feed intake (RFI) is a indicator to evaluate animal feed. This experiment was explored to study the relationship between intestinal microbiome and metabolome of ducks with different residual feed intake during laying period. Methods

Metagenomic insights into the relationship between gut microbiota and residual feed intake of small-sized meat ducks

Frontiers in Microbiology, 2023
Introduction The objective of this study was to determine the regulatory effects of gut microbiota on the feed efficiency (FE) of small-sized meat ducks by evaluating correlations between gut microbiota and residual feed intake (RFI).

Effect of breed and diet on the M. longissimus thoracis et lumborum transcriptome of steers divergent for residual feed intake

Scientific Reports, 2023
Improving cattle feed efficiency through selection of residual feed intake (RFI) is a widely accepted approach to sustainable beef production. A greater understanding of the molecular control of RFI in various breeds offered contrasting diets is ...
