Feed efficiency and enteric methane production of Nellore cattle in the feedlot and on pasture
(Csiro Publishing, 2018-01-01)
The objective of the present study was to assess the relationship between residual feed intake (RFI) evaluated in a feedlot-performance test and on pasture, and to determine the effect of feedlot RFI classification on ...
Relationships of feedlot performance, feeding behavior, rumen morphometrics, and carcass characteristics of Nellore cattle differing in phenotypic residual feed intake
(Amer Soc Animal Science, 2016-10-01)
The objective of this study was to examine the relationship of DMI fluctuation, feedlot performance, feeding behavior, rumen morphometrics, and carcass characteristics in Nellore cattle classified by residual feed intake ...
Association among residual feed intake, residual body weight gain, residual intake and body weight gain and temperament of Nellore cattle
(2014)
A study was conducted to investigate association among residual feed intake (RFI), residual body weight gain (RG), residual intake and body weight gain (RIG) and temperament of Nellore (Bos indicus) young bulls (n = 44; ...
Apparent digestibility and ingestive behavior of Nellore bulls with low and high residual feed intake
(Springer, 2022-10-01)
The objective of this study was to determine the correlation between ingestive behavior, apparent digestibility, and residual feed intake (RFI) of finishing Nellore bulls fed a high concentrate diet. One hundred and twenty ...
Residual feed intake of nellore calves is not repeatable across pre and post weaning periodsConsumo alimentar residual de bezerros Nelore na pré e pós-desmama tem baixa repetibilidade
(2021-01-01)
This study measured milk and solid feed intake in pre- weaning period and feed intake in postweaning period of Nellore calves, and to correlated them with performance traits and ingestive behavior of animals classified as ...
Relationships of the Microbial Communities with Rumen Epithelium Development of Nellore Cattle Finished in Feedlot Differing in Phenotypic Residual Feed Intake
(2022-04-01)
The objective of this study was to examine the relationships among ruminal microbial community, rumen morphometrics, feeding behavior, feedlot performance, and carcass characteristics of Nellore cattle, classified by ...
Genome-wide association analysis of feed intake and residual feed intake in Nellore cattle
(Biomed Central Ltd., 2014-02-11)
Background: 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 ...
Global liver gene expression differences in Nelore steers with divergent residual feed intake phenotypes
(Biomed Central Ltd, 2015-03-25)
Background: Efficiency of feed utilization is important for animal production because it can reduce greenhouse gas emissions and improve industry profitability. However, the genetic basis of feed utilization in livestock ...
