Rumen microbiome composition and functionality is linked to animal feed efficiency,
particularly for bovine ruminants. To investigate this in sheep, we compared rumen bacterial …

Background Residual feed intake (RFI) describes an animal's feed efficiency independent of
growth performance. The objective of this study was to determine differences in growth …

Energy is a major cost component in diets for poultry. We hypothesized that the
supplementation of emulsifier blends in broiler diets may contribute to the efficient utilization …

The aim was to evaluate growth, carcass traits, feed efficiency reranking, body composition,
calpain system activity and meat quality in Nellore steers that were phenotypically ranked for …

The purpose of this study was to identify genomic regions associated with carcass traits in
an experimental Nelore cattle population. The studied data set contained 2,306 ultrasound …

The objectives of this study were to estimate genetic parameters for indicator traits of feed
efficiency and to recommend traits that would result in better responses to selection for …

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 …

Five hundred and seventy-five Nellore steers were evaluated for residual feed intake and
residual feed intake and gain and their relationships between carcass, non-carcass and …

Abstract Residual Feed Intake (RFI) is an economically relevant trait in beef cattle. Among
the molecular regulatory mechanisms, microRNAs (miRNAs) are an important dimension in …

This study investigated the possible mechanisms for explaining interanimal variation in
efficiency of feed utilization in intact male Holstein calves. Additionally, we examined …
