Physiologically based pharmacokinetic (PBPK) models for chemicals in food animals are a
useful tool in estimating chemical tissue residues and withdrawal intervals. Physiological …

This chapter reviews the molecular physiology of feed efficiency in beef cattle and highlights
significant variation across a variety of metabolic organs and constituent biochemical …

Background The selection of beef cattle for feed efficiency (FE) traits is very important not
only for productive and economic efficiency but also for reduced environmental impact of …

A better understanding of the factors regulating feed efficiency and their potential as
predictors of feed efficiency in cattle is needed. Therefore, the potential of three classes of …

This study examined the relationship between feed efficiency and performance, and feeding
behavior, blood metabolic variables, and various ultrasonic measurements in finishing beef …

The objectives of this study were to quantify the phenotypic variation in residual feed intake
(RFI) in pregnant beef heifers offered a grass silage diet and to characterize their …

ABSTRACT A genome-wide association study using the Illumina 50K BeadChip included
38,745 SNP on 29 BTA analyzed on 751 animals, including 33 purebreds and 718 …

This study examined the relationship of residual feed intake (RFI) with digestion, body
composition, carcass traits and visceral organ weights in beef bulls offered a high …

This study aimed to evaluate whether the host genetic background impact the ruminal
microbial communities of the progeny of sires from three different breeds under different …

Bone weight is critical to affect body conformation and stature in cattle. In this study, we
conducted a genome-wide association study for bone weight in Chinese Simmental beef …
